Your conversations are encrypted client-side before being stored, and your password never leaves your device.\n\n## Features\n\n- 🔒 **Client-side encryption** - All chats encrypted with AES-256-GCM before storage\n- 🔑 **Master password protection** - Single password protects all your conversations\n- 💾 **Self-hosted on Val Town** - Your data stays in your own Val Town SQLite database\n- 🚫 **No tracking** - No analytics, no third parties\n- 🧠 **Local AI** - Uses WebLLM to run AI models directly in your browser\n- 🎛️ **Multiple AI models** - Choose between light, medium, and large models\n- 🍴 **Fork-friendly** - Easy to remix and run your own instance\n\n## How It Works\n\n1. **Set a master password** on first use to protect all your chats\n2. **Create unlimited chats** with custom names\n3. **Your messages are encrypted** in the browser using your master password\n4. **Encrypted data is stored** in your Val Town SQLite database\n5. **Only you can decrypt** your chats with the correct password\n\nYour password is never sent to the server. Encryption happens entirely in your browser.\n\n## Quick Start: Remix This Val\n\n### Step 1: Fork the Val\n\n1. Click the \"Remix\" button on Val Town (or fork this repository)\n2. This creates your own private copy of the app\n\n### Step 2: Set Up Security\n\nWhen you first run your forked val, check the **console logs**. You'll see a message like:\n\n```\n⚠️ STORAGE_API_KEY not set! Auto-generated key: a1b2c3d4-e5f6-7890-abcd-ef1234567890\n⚠️ Save this key to your STORAGE_API_KEY environment variable!\n```\n\n**Important:** Save this API key! It protects your storage endpoint.\n\n#### To set the environment variable:\n\n1. Go to your Val Town settings\n2. Navigate to **Environment Variables**\n3. Add a new variable:\n - **Name:** `STORAGE_API_KEY`\n - **Value:** (paste the key from console logs)\n4. Save and restart your val\n\n### Step 3: Update the Storage URL\n\nIn `lib/api.ts`, update line 3 with your storage val URL:\n\n```typescript\nconst STORAGE_URL = \"https://your-username--your-storage-val-id.web.val.run\";\n```\n\nYou can find this URL from your forked storage val.\n\n### Step 4: Use Your App\n\nVisit your main val's URL:\n1. Set a strong master password on first visit\n2. Create your first chat with the \"+ New Chat\" button\n3. Select your preferred AI model from the dropdown\n4. Start chatting - all messages are automatically encrypted and saved!\n\n## Security Features\n\n### What's Protected\n\n✅ **SQL Injection Prevention** - All database queries use parameterized statements\n✅ **API Authentication** - Storage endpoint requires API key\n✅ **Client-side Encryption** - AES-256-GCM with PBKDF2 key derivation\n✅ **Master Password Protection** - Single password encrypts all conversations\n✅ **Session Management** - Password stored only in sessionStorage, cleared on lock\n\n### Encryption Details\n\n- **Algorithm:** AES-GCM (256-bit)\n- **Key Derivation:** PBKDF2 with 100,000 iterations\n- **Random Salt & IV:** Generated for each encryption\n- **Password:** Never leaves your device\n\n### What's Stored in the Database\n\nYour Val Town SQLite database stores:\n- Chat ID (random UUID)\n- Chat name (plain text)\n- Encrypted chat data (ciphertext + salt + IV)\n- Timestamps\n\n**Without your password, the encrypted data is unreadable.**\n\n## Environment Variables\n\n| Variable | Required | Description |\n|----------|----------|-------------|\n| `STORAGE_API_KEY` | **Yes** | Protects your storage API from unauthorized access |\n| `FRONTEND_URL` | No | Optional CORS restriction (e.g., `https://yourapp.val.run`) |\n\n## Architecture\n\n```\n┌─────────────────┐\n│ Browser │\n│ (React App) │\n│ │\n│ • WebLLM AI │\n│ • Encryption │\n│ • UI │\n└────────┬────────┘\n │\n │ HTTPS + API Key\n │\n┌────────▼────────┐\n│ Val Town │\n│ Storage API │\n│ │\n│ • SQLite DB │\n│ • Auth Check │\n└─────────────────┘\n```\n\n## File Structure\n\n```\n├── main.ts # Entry point, serves HTML\n├── App.tsx # Main app with master password flow\n├── api/\n│ └── storage.ts # Storage API with authentication\n├── lib/\n│ ├── api.ts # Client-side API calls\n│ ├── crypto.ts # Encryption/decryption logic\n│ └── models.ts # AI model definitions\n├── hooks/\n│ ├── useEncryption.ts # Encryption state management\n│ └── useWebLLM.ts # AI model integration\n├── screens/\n│ ├── MasterPasswordScreen.tsx # Password creation/verification\n│ └── MainScreen.tsx # Main chat interface with sidebar\n└── components/\n ├── MessageBubble.tsx # Message display\n ├── StatusBadge.tsx # AI status indicator\n ├── EmptyState.tsx # Empty state UI\n ├── ModelSelector.tsx # AI model selection dropdown\n ├── OptionsMenu.tsx # Lock/delete options menu\n └── ChatNameModal.tsx # Create/rename chat modal\n```\n\n## Usage Tips\n\n### Strong Master Password\n\nUse a strong, unique master password. Since encryption happens client-side, your master password is the only thing protecting ALL your data.\n\n### Password Recovery\n\n**There is no password recovery.** If you forget your master password, ALL your chat data is permanently inaccessible. This is by design - the server (in this case Val-Town) won't have access to your data or password.\n\n### AI Model Selection\n\nThe app offers three AI models:\n- **Phi-3 Mini (2.3GB)** - Fastest, best for quick responses\n- **Llama 3.2 3B (1.9GB)** - Balanced performance and quality (default)\n- **Llama 3.1 8B (4.7GB)** - Highest quality responses, slower\n\nModels download to your browser once and persist. You can switch models anytime in the chat interface.\n\n\n## Troubleshooting\n\n### \"Unauthorized\" Error\n\n**Problem:** API calls return 401 Unauthorized\n\n**Solution:**\n1. Check that `STORAGE_API_KEY` is set in environment variables\n2. Make sure the key matches in both your main val and storage val\n3. Restart both vals after setting the variable\n\n### \"Wrong Password\" Error\n\n**Problem:** Can't unlock the app\n\n**Solution:**\n- Double-check your master password (passwords are case-sensitive)\n- There is no password recovery - if you forgot it, all your chats are inaccessible\n\n### Chat List Empty\n\n**Problem:** No chats appear on home screen\n\n**Solution:**\n1. Check browser console for errors\n2. Verify `STORAGE_URL` in `lib/api.ts` points to your storage val\n3. Ensure storage val is running and accessible\n\n### AI Model Not Loading\n\n**Problem:** WebLLM status shows error\n\n**Solution:**\n- WebLLM downloads models to browser (can be 1-2 GB)\n- Check your internet connection\n- Try refreshing the page\n- Check browser console for specific errors\n\n## Advanced Configuration\n\n### Change PBKDF2 Iterations\n\nFor stronger encryption, increase iterations in `lib/crypto.ts` (line 25):\n\n```typescript\niterations: 600000, // Increased from 100,000\n```\n\n**Trade-off:** Higher security, slower encryption/decryption.\n\n### Restrict CORS\n\nTo only allow requests from your frontend:\n\n1. Set `FRONTEND_URL` environment variable\n2. Value: `https://your-main-val.val.run`\n3. Restart storage val\n\nThis prevents other websites from calling your API (browser-level protection).\n\n### Add More AI Models\n\nTo add additional AI models beyond the three included:\n\n1. Edit `lib/models.ts` to add model definitions\n2. Add to the `AVAILABLE_MODELS` array with model ID, name, size, and description\n3. Find compatible model IDs in the [WebLLM documentation](https://github.com/mlc-ai/web-llm)\n\n### Lock and Security Features\n\n- **Lock App**: Click the options menu (•••) in the bottom-right to lock the app. This clears your password from the session and returns to the master password screen.\n- **Delete All Data**: Use the options menu to permanently delete all chats from your database. This action cannot be undone.\n\n## Privacy & Data\n\n### What Data is Collected\n\n**None.** This app doesn't collect, track, or transmit any data beyond what's necessary for functionality:\n\n- Your chats are encrypted and stored in **your** Val Town SQLite database\n- Your password never leaves your browser\n- No analytics, no tracking, no third parties\n\n### Who Can Access Your Data\n\n**Only you.** When you fork this val:\n\n- You own the Val Town vals\n- You control the database\n- You set the API key\n- You hold the encryption passwords\n\nNo one else (including the original author) can access your chats.\n\n## Contributing\n\nFound a bug or want to improve the code? Feel free to:\n\n1. Fork this val\n2. Make your improvements\n3. Share your enhanced version!\n\nThis is open source - make it your own.\n\n## Security Considerations\n\nWhile this app implements strong encryption and security practices, please note:\n\n- ⚠️ This is a personal project, not audited by security professionals\n- ⚠️ API keys are visible in browser DevTools (use strong, unique keys)\n- ⚠️ Val Town is a public platform - keep your vals private if needed\n- ⚠️ No rate limiting implemented (could be added if needed)\n\nFor maximum security:\n- Use strong, unique passwords\n- Set a strong `STORAGE_API_KEY`\n- Keep your Val Town account secure\n- Consider enabling 2FA on your Val Town account\n\n## Credits\n\nBuilt with:\n- [Val Town](https://val.town) - Hosting & SQLite\n- [React](https://react.dev) - UI framework\n- [WebLLM](https://github.com/mlc-ai/web-llm) - Browser-based AI\n- [Web Crypto API](https://developer.mozilla.org/en-US/docs/Web/API/Web_Crypto_API) - Encryption\n- [Tailwind CSS](https://tailwindcss.com) - Styling\n\n## License\n\nMIT License - Feel free to fork, remix, and make it your own!\n\n---\n\n**Remember:** Your master password is your key.

HTTP Trigger\n\n- Create web APIs and endpoints\n- Handle HTTP requests and responses\n- Example structure:\n\n```ts\nexport default async function (req: Request) {\n return new Response(\"Hello World\");\n}\n```\n\nFiles that are HTTP triggers have http in their name like `foobar.http.tsx`\n\n### 2. Cron Triggers\n\n- Run on a schedule\n- Use cron expressions for timing\n- Example structure:\n\n```ts\nexport default async function () {\n // Scheduled task code\n}\n```\n\nFiles that are Cron triggers have cron in their name like `foobar.cron.tsx`\n\n### 3. Email Triggers\n\n- Process incoming emails\n- Handle email-based workflows\n- Example structure:\n\n```ts\nexport default async function (email: Email) {\n // Process email\n}\n```\n\nFiles that are Email triggers have email in their name like `foobar.email.tsx`\n\n\n## Val Town Standard Libraries\n\nVal Town provides several hosted services and utility functions.\n\n### Blob Storage\n\n```ts\nimport { blob } from \"https://esm.town/v/std/blob\";\nawait blob.setJSON(\"myKey\", { hello: \"world\" });\nlet blobDemo = await blob.getJSON(\"myKey\");\nlet appKeys = await blob.list(\"app_\");\nawait blob.delete(\"myKey\");\n```\n\n### SQLite\n\n```ts\nimport { sqlite } from \"https://esm.town/v/stevekrouse/sqlite\";\nconst TABLE_NAME = 'todo_app_users_2';\n// Create table - do this before usage and change table name when modifying schema\nawait sqlite.execute(`CREATE TABLE IF NOT EXISTS ${TABLE_NAME} (\n id INTEGER PRIMARY KEY AUTOINCREMENT,\n name TEXT NOT NULL\n)`);\n// Query data\nconst result = await sqlite.execute(`SELECT * FROM ${TABLE_NAME} WHERE id = ?`, [1]);\n```\n\nNote: When changing a SQLite table's schema, change the table's name (e.g., add _2 or _3) to create a fresh table.\n\n### OpenAI\n\n```ts\nimport { OpenAI } from \"https://esm.town/v/std/openai\";\nconst openai = new OpenAI();\nconst completion = await openai.chat.completions.create({\n messages: [\n { role: \"user\", content: \"Say hello in a creative way\" },\n ],\n model: \"gpt-4o-mini\",\n max_tokens: 30,\n});\n```\n\n### Email\n\n```ts\nimport { email } from \"https://esm.town/v/std/email\";\n// By default emails the owner of the val\nawait email({ \n subject: \"Hi\", \n text: \"Hi\", \n html: \"

Hi

\"\n});\n```\n\n## Val Town Utility Functions\n\nVal Town provides several utility functions to help with common project tasks.\n\n### Importing Utilities\n\nAlways import utilities with version pins to avoid breaking changes:\n\n```ts\nimport { parseProject, readFile, serveFile } from \"https://esm.town/v/std/utils@85-main/index.ts\";\n```\n\n### Available Utilities\n\n\n#### **serveFile** - Serve project files with proper content types\n\nFor example, in Hono:\n\n```ts\n// serve all files in frontend/ and shared/\napp.get(\"/frontend/*\", c => serveFile(c.req.path, import.meta.url));\napp.get(\"/shared/*\", c => serveFile(c.req.path, import.meta.url));\n```\n\n#### **readFile** - Read files from within the project:\n\n```ts\n// Read a file from the project\nconst fileContent = await readFile(\"/frontend/index.html\", import.meta.url);\n```\n\n#### **listFiles** - List all files in the project\n\n```ts\nconst files = await listFiles(import.meta.url);\n```\n\n#### **parseProject** - Extract information about the current project from import.meta.url\n\nThis is useful for including info for linking back to a val, ie in \"view source\" urls:\n\n```ts\nconst projectVal = parseProject(import.meta.url);\nconsole.log(projectVal.username); // Owner of the project\nconsole.log(projectVal.name); // Project name\nconsole.log(projectVal.version); // Version number\nconsole.log(projectVal.branch); // Branch name\nconsole.log(projectVal.links.self.project); // URL to the project page\n```\n\nHowever, it's *extremely importing* to note that `parseProject` and other Standard Library utilities ONLY RUN ON THE SERVER.\nIf you need access to this data on the client, run it in the server and pass it to the client by splicing it into the HTML page\nor by making an API request for it.\n\n## Val Town Platform Specifics\n\n- **Redirects:** Use `return new Response(null, { status: 302, headers: { Location: \"/place/to/redirect\" }})` instead of `Response.redirect` which is broken\n- **Images:** Avoid external images or base64 images. Use emojis, unicode symbols, or icon fonts/libraries instead\n- **AI Image:** To inline generate an AI image use: `

`\n- **Storage:** DO NOT use the Deno KV module for storage\n- **Browser APIs:** DO NOT use the `alert()`, `prompt()`, or `confirm()` methods\n- **Weather Data:** Use open-meteo for weather data (doesn't require API keys) unless otherwise specified\n- **View Source:** Add a view source link by importing & using `import.meta.url.replace(\"ems.sh\", \"val.town)\"` (or passing this data to the client) and include `target=\"_top\"` attribute\n- **Error Debugging:** Add `` to HTML to capture client-side errors\n- **Error Handling:** Only use try...catch when there's a clear local resolution; Avoid catches that merely log or return 500s. Let errors bubble up with full context\n- **Environment Variables:** Use `Deno.env.get('keyname')` when you need to, but generally prefer APIs that don't require keys\n- **Imports:** Use `https://esm.sh` for npm and Deno dependencies to ensure compatibility on server and browser\n- **Storage Strategy:** Only use backend storage if explicitly required; prefer simple static client-side sites\n- **React Configuration:** When using React libraries, pin versions with `?deps=react@18.2.0,react-dom@18.2.0` and start the file with `/** @jsxImportSource https://esm.sh/react@18.2.0 */`\n- Ensure all React dependencies and sub-dependencies are pinned to the same version\n- **Styling:** Default to using TailwindCSS via `` unless otherwise specified\n\n## Project Structure and Design Patterns\n\n### Recommended Directory Structure\n```\n├── backend/\n│ ├── database/\n│ │ ├── migrations.ts # Schema definitions\n│ │ ├── queries.ts # DB query functions\n│ │ └── README.md\n│ └── routes/ # Route modules\n│ ├── [route].ts\n│ └── static.ts # Static file serving\n│ ├── index.ts # Main entry point\n│ └── README.md\n├── frontend/\n│ ├── components/\n│ │ ├── App.tsx\n│ │ └── [Component].tsx\n│ ├── favicon.svg\n│ ├── index.html # Main HTML template\n│ ├── index.tsx # Frontend JS entry point\n│ ├── README.md\n│ └── style.css\n├── README.md\n└── shared/\n ├── README.md\n └── utils.ts # Shared types and functions\n```\n\n### Backend (Hono) Best Practices\n\n- Hono is the recommended API framework\n- Main entry point should be `backend/index.ts`\n- **Static asset serving:** Use the utility functions to read and serve project files:\n ```ts\n import { readFile, serveFile } from \"https://esm.town/v/std/utils@85-main/index.ts\";\n \n // serve all files in frontend/ and shared/\n app.get(\"/frontend/*\", c => serveFile(c.req.path, import.meta.url));\n app.get(\"/shared/*\", c => serveFile(c.req.path, import.meta.url));\n \n // For index.html, often you'll want to bootstrap with initial data\n app.get(\"/\", async c => {\n let html = await readFile(\"/frontend/index.html\", import.meta.url);\n \n // Inject data to avoid extra round-trips\n const initialData = await fetchInitialData();\n const dataScript = ``;\n \n html = html.replace(\"\", `${dataScript}`);\n return c.html(html);\n });\n ```\n- Create RESTful API routes for CRUD operations\n- Always include this snippet at the top-level Hono app to re-throwing errors to see full stack traces:\n ```ts\n // Unwrap Hono errors to see original error details\n app.onError((err, c) => {\n throw err;\n });\n ```\n\n### Database Patterns\n- Run migrations on startup or comment out for performance\n- Change table names when modifying schemas rather than altering\n- Export clear query functions with proper TypeScript typing\n\n## Common Gotchas and Solutions\n\n1. **Environment Limitations:** \n - Val Town runs on Deno in a serverless context, not Node.js\n - Code in `shared/` must work in both frontend and backend environments\n - Cannot use `Deno` keyword in shared code\n - Use `https://esm.sh` for imports that work in both environments\n\n2. **SQLite Peculiarities:**\n - Limited support for ALTER TABLE operations\n - Create new tables with updated schemas and copy data when needed\n - Always run table creation before querying\n\n3. **React Configuration:**\n - All React dependencies must be pinned to 18.2.0\n - Always include `@jsxImportSource https://esm.sh/react@18.2.0` at the top of React files\n - Rendering issues often come from mismatched React versions\n\n4. **File Handling:**\n - Val Town only supports text files, not binary\n - Use the provided utilities to read files across branches and forks\n - For files in the project, use `readFile` helpers\n\n5. **API Design:**\n - `fetch` handler is the entry point for HTTP vals\n - Run the Hono app with `export default app.fetch // This is the entry point for HTTP vals`\n\n",[],[274],"39fb6a8c-ea79-11f0-b20b-42dde27851f2",".vtignore","019b8ff3-e09d-72fb-9858-732c309d7ca9",["D",1767646683299],".git\n.vscode\n.cursorrules\n.DS_Store\n.claude\nnode_modules\nvendor",[],[281],"43f9b464-ece8-11f0-9d7c-42dde27851f2","MasterPasswordScreen.tsx","019b8ff3-e09d-72fb-9858-6984d64e5407","019b8ff3-e09d-72fb-9858-6dcfd06146b2",50,["D",1767914276458],"/** @jsxImportSource https://esm.sh/react */\nimport React, { useState } from \"https://esm.sh/react\";\nimport type { MasterPasswordMode } from \"../types.ts\";\n\ntype Props = {\n mode: MasterPasswordMode;\n onUnlock: (password: string) => void;\n onCreate: (password: string) => void;\n error?: string | null;\n isLoading?: boolean;\n};\n\nexport function MasterPasswordScreen({\n mode,\n onUnlock,\n onCreate,\n error,\n isLoading,\n}: Props) {\n const [password, setPassword] = useState(\"\");\n const [validationError, setValidationError] = useState(\"\");\n const [hasWebGPU, setHasWebGPU] = useState(true);
