That chosen reply is their voice.\n\n## Why it works\n\nHuman talk is largely `predictable moves` — agreeing, staying neutral,\ndisagreeing, showing interest, keeping it light, steering. AIVoice turns each\nof those moves into a selectable option, so a person who can't speak is\nexpressing the same conversational intent, just by choosing.\n\n## Feature rundown\n\n- **Chat interface** — verbal partner's words on the right, the person's\n chosen replies on the left (tagged with the direction they chose).\n- **Response options** — 4-6 different conversational directions to pick from\n on every exchange.\n- **Typed replies** — a trusted person can type a custom reply on their behalf.\n- **Profile** — name, **age**, closeness, personality traits, likes, a long\n free-form \"about this person\" field (more detail = better responses), and\n which directions to offer.\n- **Age-appropriateness is enforced** — it's written into the system prompt as\n a hard rule. A 20-year-old profile gets 20-year-old language; a 6-year-old\n profile never gets adult language, no matter what the conversation partner\n says.\n- **Multiple LLM providers** — OpenAI, DeepSeek, OpenRouter, Ollama (local),\n Anthropic, and Gemini, plus a built-in no-key demo provider so you can try it\n instantly.\n\n## Try it\n\nLive at **https://aivoice.val.run** — open the **Profile & Setup** tab first to\ndescribe the person (especially **age**), then use the Conversation tab.\n\n## Architecture\n\n```mermaid\ngraph TD\n Browser -->|GET /| Hono[index.ts · Hono]\n Hono -->|serves| Shell[frontend/root.tsx]\n Shell -->|loads| App[frontend/components/App.tsx · React chat UI]\n App -->|POST /api/respond| Hono\n Hono --> generateOptions[llm.ts · provider abstraction]\n generateOptions --> providers[OpenAI · DeepSeek · OpenRouter · Ollama · Anthropic · Gemini]\n Hono --> store[store.ts · SQLite]\n store --> profile[(profile)]\n store --> messages[(conversation)]\n```\n\n## Setup (environment variables)\n\nThe **demo provider works with no configuration**.

Publishing your val bumps its version, which changes every URL, so\ncaches invalidate automatically. Old-version URLs return 404 after a publish\n(like Next.js build assets); a reload picks up the new version.\n\nWhat changed in the template:\n\n- `frontend/index.html` → [`frontend/root.tsx`](/frontend/root.tsx): the HTML\n shell is now JSX and stamps asset URLs with `immutableFileUrl()`\n- [`index.ts`](/index.ts): serves `Root()` at `/`, and one\n `app.get(\"/__immutable/*\", (c) => serveImmutableFile(c.req.path))` route\n serves all frontend files\n\n### Upgrading an existing remix\n\nYour copy of this template doesn't update automatically. Two options:\n\n**Minimal (most of the benefit):** point both routes at `serveImmutableFile` —\nyour existing bare URLs redirect into versioned space, the new route serves\nthem, and the whole module graph gets cached (costs one redirect per page view):\n\n```ts\nimport { serveImmutableFile } from \"https://esm.town/v/std/utils/index.ts\";\n\napp.get(\"/__immutable/*\", (c) => serveImmutableFile(c.req.path));\napp.get(\"/frontend/**/*\", (c) => serveImmutableFile(c.req.path)); // was serveFile\n```\n\n**Full upgrade (also removes the redirect):** three self-contained steps —\nno other files needed. Adjust the ``, favicon, and body of `Root()` to\nmatch your app's existing `index.html`, and stamp anything else your shell\nreferences directly (images, css) with `immutableFileUrl()`.\n\n1. Create `frontend/root.tsx`:\n\n```tsx\n/** @jsxImportSource npm:hono@4/jsx */\nimport { raw } from \"npm:hono@4/html\";\nimport { immutableFileUrl } from \"https://esm.town/v/std/utils/index.ts\";\n\n// The HTML shell for the app. It is never cached, so immutableFileUrl can stamp\n// the current val version into each asset URL — the browser caches those\n// immutably, and publishing the val changes the URLs, refetching exactly once.\nexport function Root() {\n return (\n <>\n {raw(\"<!DOCTYPE html>\")}\n <html lang=\"en\">\n <head>\n <meta charSet=\"UTF-8\" />\n <meta name=\"viewport\" content=\"width=device-width, initial-scale=1.0\" />\n <title>React Hono Val Town Starter\n
