Connect your bank via [Teller](https://teller.io) (a developer-friendly bank API — free for personal use, supports Chase, BofA, Amex, and most major US banks) or upload CSVs, get AI-powered categorization, and see where your money goes.\n\n> **Template note** — first time you open the dashboard, it'll be pre-populated with ~40 demo transactions across 3 months so you can see what it looks like without setting anything up. Connect a bank or upload your own CSV to replace them, or hit **Reset to Demo** in Settings any time to start over from the showcased state. Tables use the `sat_` prefix (**s**pend **a**gent **t**emplate + underscore) so the template's data stays isolated from any other personal burn-tracker val you may run on the same Val Town account.\n\n## How It Works\n\n![Architecture](https://kevinsuh--8ac5067e5aab11f1bb3cee650bb23af1.web.val.run/diagram.png?v=8)\n\nThe template handles the boring part — syncing transactions from banks + Venmo and classifying them with AI. Once your data lands as structured rows, **you build** whatever you want on top.\n\n**The feedback loop is the key insight**: more data + prompt refinement = better classification over time.\n\n## Two App Templates Included\n\nThe template ships with two views so you can poke around immediately on day one:\n\n- **Overview page** — Monthly burn at a glance. Stacked bar chart color-coded by category over 12 months. Click any month to drill down to individual transactions with AI reasoning.\n- **Ask Agent chat UI** — A chat interface for natural-language questions over your structured data: _\"what did I spend on travel last quarter?\"_, _\"am I on track for my savings goal?\"_, _\"which subscriptions haven't I used in 3 months?\"_\n\n## From There: Structured Data You Can Remix\n\nThe two dashboards are a starting point. From there, the clean classified transaction table is yours to remix into whatever personal finance workflow you want. Some directions worth exploring:\n\n- **Find & cancel subscriptions** — \"Show me all my recurring subscriptions. Which ones haven't I used in 3 months? Help me cancel them by next billing cycle.\"\n- **Budget guardrails with alerts** — Set up a cron that texts you when a category (restaurants, golf, shopping) exceeds your monthly budget. Proactive, not reactive.\n- **Spending trends & accountability** — \"How much do I spend on food per day on average? How do I trend that down?\" Have the agent check in weekly and keep you honest.\n- **Smart digest emails** — Weekly or monthly email: \"You spent $X this month, up 15% from last month. Top 3 categories that grew: ...\" (Val Town free tier sends emails to yourself via `std/email`)\n- **Custom automations** — Val Town crons + Claude + your categorized data = any workflow you can imagine. Budget forecasting, tax prep summaries, spending comparisons across months.\n\n## Setup (5 minutes)\n\n1. **Remix this project** on Val Town.\n2. **Set `TELLER_APP_ID`** (Settings > Environment Variables). Get one from [teller.io](https://teller.io) — needed to connect a real or sandbox bank. See [Teller setup](#teller-setup) at the bottom for the full walkthrough.\n3. **Set `ANTHROPIC_API_KEY`** (Settings > Environment Variables). Get a key from [anthropic.com](https://anthropic.com) — needed for AI classification + the Ask tab.\n4. **Open the dashboard.** It's already pre-populated with ~40 demo transactions so you can see what the app looks like before connecting anything real.\n5. Click **Connect Bank** in Settings and link an account. Or upload a CSV (Chase, Amex, Venmo).\n6. Hit **Preview Classification** on the dashboard banner to categorize transactions with AI.\n\n## Categories\n\nThe template ships with these defaults:\n\n> Housing, Food, Transportation, Shopping, Entertainment, Health, Subscriptions, Bills, Travel, Investments, Transfers, Salary, Income, Gifts, Other\n\nThese feed directly into the AI classifier's allowed set (tool-use enum) so the model can't invent categories. Edit them on the **Settings page → Categories** card:\n\n- **Add** a new category — type a name and save.\n- **Rename** in place by editing the input.\n- **Remove** any category except `Other` (the universal fallback).\n\nRemoving a category sends every transaction classified to it back to **unclassified** so you can re-review and re-classify them from the dashboard banner.\n\nYou can also bias the classifier with natural-language rules in the **Classification Prompt** card:\n\n```\n- DoorDash and UberEats are Food, not Transportation\n- Recurring charges like Netflix are Subscriptions\n- Venmo payments TO someone are actual spend, not Transfers\n```\n\nHit \"Re-classify All\" after updating the prompt. Manual category overrides on individual transactions are preserved.\n\n## Data Sources\n\n| Source | Provider | Cost | Best For |\n| -------------------- | -------- | ------------------------- | ----------------------- |\n| Banks & credit cards | Teller | Free (up to 100 accounts) | Chase, BofA, Amex, etc. |\n| CSV upload | Built-in | Free | Any bank, manual import |\n\nAll sources flow into the same transaction table. Connect N Teller accounts — they all normalize and classify together.\n\n## Classification Engine\n\n**AI classification** — Claude Haiku batch-classifies uncategorized transactions using Anthropic tool use with JSON schema enforcement. The `category` field is constrained to an `enum` — no hallucinated categories possible.\n\n**Interactive flow:**\n\n1. Click \"Review & Classify\" banner — drawer opens with unclassified transactions\n2. Review/edit the classification prompt — click \"Preview Classification\"\n3. Review results with color-coded category pills + confidence scores\n4. Edit prompt inline and \"Retry\" or \"Approve All\" to commit\n\n**Manual overrides** — Click any transaction to re-categorize. Manual changes stick permanently and are never re-classified.\n\n## Files\n\n| File | Type | Purpose |\n| -------------------- | ---------------- | ------------------------------------------------------------ |\n| `app.ts` | http | Dashboard, settings, API routes |\n| `db.ts` | script | SQLite schema, config helpers, default categories, demo seed |\n| `lib.ts` | script | Formatting, HTML shell, category colors, Settings JS helpers |\n| `classify-engine.ts` | script | LLM classification engine (tool use with JSON schema) |\n| `classify-ui.ts` | script | Classification drawer UI |\n| `classify.ts` | interval (daily) | Thin cron wrapper — calls `runClassification()` |\n| `sync-engine.ts` | script | Teller mTLS sync logic |\n| `sync.ts` | interval (15min) | Thin cron wrapper — calls `runSync()` |\n\n## Teller setup\n\nThis template ships with the **author's own Teller App ID baked in as a default** (`app_pr4h9kg679tq045oi0000`) so the Connect Bank button works the moment you remix. **You must replace it with your own** before sharing the val publicly or using it seriously — App IDs are public identifiers tied to a developer account, and sandbox transactions made under someone else's App ID show up in their Teller dashboard.\n\n**Steps:**\n\n1. Sign up at [teller.io](https://teller.io) (free, no credit card, ~30 seconds).\n2. From your Teller dashboard, copy your **Application ID** (format: `app_xxxxxxxxxxxxx` — this is a public string, not a secret).\n3. On your remixed val, add it as an env var: `TELLER_APP_ID = app_yourIdHere`. It overrides the baked-in default automatically (`lib.ts:11`).\n4. Refresh the Settings page — the Connect Bank button now uses your App ID.\n\n**Teller environment modes:**\n\n| `TELLER_ENV` | Certs required? | Real bank data? | When to use |\n| ------------------- | ---------------------------------- | --------------- | ----------------------------------------------------------------------- |\n| `sandbox` (default) | No | No | Default — fake test institutions, sandbox credentials shown in Settings |\n| `development` | Yes (`TELLER_CERT` + `TELLER_KEY`) | Limited | Teller's dev tier — small set of real institutions, no PCI scope |\n| `production` | Yes (`TELLER_CERT` + `TELLER_KEY`) | Yes | Live bank connections — requires Teller paid plan |\n\nFor sandbox, **no mTLS certs are needed.** When you click \"Connect Bank\" with `TELLER_ENV=sandbox`, Teller Connect opens with a list of fake institutions. Use the test credentials shown in the \"View sandbox test credentials\" accordion on the Settings page:\n\n- Username: `username` (or `otp` / `challenge` for MFA flows)\n- Password: `password`\n- OTP code: `0000` (if username = `otp`)\n- Challenge answer: `blue` (if username = `challenge`)\n\nFor **production**, click \"View production setup (real banks)\" on the Settings page — Teller's dashboard issues your mTLS certificate + private key after you apply for production access (free up to 100 accounts, requires ID verification). Paste both PEMs into `TELLER_CERT` and `TELLER_KEY` env vars and set `TELLER_ENV=production`.\n\nSee the [Teller sandbox docs](https://teller.io/docs/guides/sandbox) and [production docs](https://teller.io/docs/guides/production) for full details.\n\n## Cost\n\n- **Teller**: Free (up to 100 accounts)\n- **Claude Haiku**: ~$0.01/day for ~100 transactions\n- **Val Town**: Free tier works for personal use\n",[202],"pulls",0,"branches","forks","envVars",{"_216":63,"_218":209},"connections",{"_216":209,"_217":209},"count","unfilledCount","emptyCount",{"_43":201,"_32":202,"_30":203,"_142":-5,"_41":42,"_40":204,"_144":25,"_38":253,"_13":156,"_33":34,"_35":206,"_24":25,"_149":-5,"_229":254,"_27":255},{"_43":193,"_32":194,"_30":57,"_142":-5,"_41":42,"_40":195,"_144":25,"_38":250,"_13":197,"_33":198,"_35":199,"_24":25,"_149":-5,"_229":251,"_27":252},{"_43":185,"_32":186,"_30":187,"_142":-5,"_41":42,"_40":188,"_144":25,"_38":247,"_13":190,"_33":34,"_35":191,"_24":25,"_149":-5,"_229":248,"_27":249},{"_43":178,"_32":179,"_30":180,"_142":-5,"_41":42,"_40":181,"_144":59,"_38":244,"_13":156,"_33":34,"_35":183,"_24":25,"_149":-5,"_229":245,"_27":246},{"_43":170,"_32":171,"_30":172,"_142":-5,"_41":42,"_40":173,"_144":59,"_38":241,"_13":175,"_33":147,"_35":176,"_24":25,"_149":-5,"_229":242,"_27":243},{"_43":162,"_32":163,"_30":164,"_142":-5,"_41":42,"_40":165,"_144":25,"_38":238,"_13":167,"_33":34,"_35":168,"_24":25,"_149":-5,"_229":239,"_27":240},{"_43":159,"_32":28,"_30":31,"_142":-5,"_41":42,"_40":14,"_144":25,"_38":235,"_13":156,"_33":34,"_35":37,"_24":25,"_149":-5,"_229":236,"_27":237},{"_43":151,"_32":152,"_30":153,"_142":-5,"_41":42,"_40":154,"_144":25,"_38":232,"_13":156,"_33":34,"_35":157,"_24":25,"_149":-5,"_229":233,"_27":234},{"_43":139,"_32":140,"_30":141,"_142":-5,"_41":42,"_40":143,"_144":59,"_38":228,"_13":146,"_33":147,"_35":148,"_24":25,"_149":-5,"_229":230,"_27":231},["D",1779741957609],"children",[],[140],["D",1779912789596],[],[152],["D",1779985847698],[],[28],["D",1779984514370],[],[163],["D",1779903197447],[],[171],["D",1779901810486],[],[179],["D",1779912789892],[],[186],["D",1779985412407],[],[194],["D",1779983505040],[],[202],["D",1779740379107],["D",1789504908499],{"_100":99,"_107":103},{"_100":99,"_101":-5,"_102":103,"_18":55,"_104":105,"_106":25},{"_13":89,"_32":90,"_43":42,"_91":44,"_92":-5,"_93":-5,"_94":-5,"_95":-5,"_96":-5,"_97":45,"_98":99},"ctx",{"_82":-5,"_127":294,"_295":296,"_297":298,"_299":25,"_300":25,"_301":25,"_302":59,"_303":-5,"_304":-7,"_305":-7,"_306":209,"_307":25,"_308":25,"_309":-5,"_310":25,"_311":25,"_312":25,"_313":-5},"ENV",{"_265":266,"_267":268,"_269":90,"_270":271,"_272":273,"_274":275,"_276":277,"_278":279,"_280":281,"_282":283,"_284":285,"_286":287,"_288":289,"_290":291,"_292":293},"REACT_APP_SENTRY_DSN","https://586020d86f05489db63a554690acf1e9@o1398359.ingest.sentry.io/6724499","RENDER_GIT_COMMIT","e87eb04e707cf64e7e532c8e8ec395f209e17f15","RENDER_GIT_BRANCH","POSTHOG_API_TOKEN","phc_nmoyuAkStEZuUp69rYlg1DZgrIt19Gx0Y4Hwf8tGgJP","POSTHOG_API_HOST","https://wart.val.town","WEB_API_TEMPLATE","https://{val}.web.val.run","APP_URL","https://www.val.town","MODULE_URL","https://esm.town","VANITY_WEB_API_TEMPLATE","https://{label}.val.run/","DENOLS_URL","https://lsp.val.town","NODE_ENV","production","CLOUDFLARE_TURNSTILE_SITE_KEY","0x4AAAAAACtaIZJH7s9rBMZ6","GOOGLE_CLIENT_ID","875989696899-jtsqkhlbdv5jrlsk8631p7ipjg3c6o62.apps.googleusercontent.com","STRIPE_PUBLISHABLE_KEY","pk_live_51N2zvWEpZTTLipIkVEwXrUG9AT0yeOOEYxszarZT1jpsZV58Ly6wlg3SltZpHN26CUalOBmUSY7adQRQiSkCZz2500qSXNkf8Y","API_URL","https://api.val.town",[],"preferencesKeybindings","default","preferencesTheme","light","preferencesFixers","preferencesCopilot","preferencesSelectionAi","preferencesCloseBrackets","preferencesChatPanelState","preferencesDprint","preferencesDenofmt","notificationCount","flagDenols","isBusinessOrgMember","businessOrgHandle","isBusinessOrgAdmin","isHigherTownieTier","navCollapsed","currentOrgId"]
