Connect your bank via [Teller](https://teller.io) or upload CSVs (Chase, Amex, Venmo), get AI-powered categorization, and see where your money goes.\n\n## How It Works\n\n![Architecture](https://kevinsuh--8ac5067e5aab11f1bb3cee650bb23af1.web.val.run/diagram.png?v=8)\n\nThe tool 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## What's Included\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 with your financial data: _\"what did I spend on travel last quarter?\"_, _\"am I on track for my savings goal?\"_\n- **Settings** — Classification prompt editor, category management with color swatches, Teller bank connection, CSV upload.\n\n## Ideas After You Remix\n\nOnce your transactions are classified, the structured data is yours to build on:\n\n- **Find & cancel subscriptions** — \"Which recurring charges haven't I used in 3 months?\"\n- **Budget guardrails** — Cron that texts you when a category exceeds your monthly budget.\n- **Smart digest emails** — Weekly email: \"You spent $X this month, up 15% from last month.\"\n- **Custom automations** — Val Town crons + Claude + your categorized data = any workflow.\n\n## Setup (5 minutes)\n\n1. **Remix this project** on Val Town.\n2. **Set `ANTHROPIC_API_KEY`** in Settings > Environment Variables ([anthropic.com](https://anthropic.com)).\n3. **Open the dashboard.** Upload a CSV (Chase, Amex, Venmo) or connect a bank via Teller.\n4. Hit **Preview Classification** on the banner to categorize transactions with AI.\n\n### Optional: Teller bank sync\n\nSet `TELLER_APP_ID` to enable automatic bank sync. Get a free App ID from [teller.io](https://teller.io) (free up to 100 accounts, no credit card required). Sandbox mode works without mTLS certificates — just use the test credentials shown on the Settings page.\n\nFor production bank connections, you'll also need `TELLER_CERT` and `TELLER_KEY` (mTLS certificate PEMs from Teller's dashboard).\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**Default categories:** Housing, Food, Transportation, Shopping, Entertainment, Health, Subscriptions, Bills, Travel, Investments, Transfers, Salary, Income, Gifts, Other\n\nCustomizable on the Settings page — add, rename, reorder, assign colors, or remove categories. Removing a category sends its transactions back to unclassified for re-review. Manual overrides on individual transactions are never re-classified.\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\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 |\n| `lib.ts` | script | Formatting, HTML shell, category colors, Settings JS |\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## 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",[199],"pulls","forks","envVars",{"_210":212,"_213":212},"connections",{"_210":56,"_211":56},"count","unfilledCount",4,"emptyCount",{"_20":198,"_13":199,"_141":200,"_143":-5,"_144":21,"_145":30,"_146":52,"_22":248,"_29":56,"_148":159,"_150":202,"_152":40,"_153":-5,"_224":249,"_98":250},{"_20":192,"_13":193,"_141":50,"_143":-5,"_144":21,"_145":30,"_146":52,"_22":245,"_29":56,"_148":195,"_150":196,"_152":40,"_153":-5,"_224":246,"_98":247},{"_20":186,"_13":187,"_141":188,"_143":-5,"_144":21,"_145":30,"_146":52,"_22":242,"_29":56,"_148":159,"_150":190,"_152":40,"_153":-5,"_224":243,"_98":244},{"_20":180,"_13":181,"_141":182,"_143":-5,"_144":21,"_145":30,"_146":52,"_22":239,"_29":56,"_148":159,"_150":184,"_152":40,"_153":-5,"_224":240,"_98":241},{"_20":174,"_13":175,"_141":176,"_143":-5,"_144":21,"_145":30,"_146":52,"_22":236,"_29":56,"_148":149,"_150":178,"_152":40,"_153":-5,"_224":237,"_98":238},{"_20":168,"_13":169,"_141":170,"_143":-5,"_144":21,"_145":30,"_146":52,"_22":233,"_29":56,"_148":159,"_150":172,"_152":40,"_153":-5,"_224":234,"_98":235},{"_20":162,"_13":163,"_141":164,"_143":-5,"_144":21,"_145":30,"_146":52,"_22":230,"_29":56,"_148":159,"_150":166,"_152":40,"_153":-5,"_224":231,"_98":232},{"_20":155,"_13":156,"_141":157,"_143":-5,"_144":21,"_145":30,"_146":52,"_22":227,"_29":56,"_148":159,"_150":160,"_152":40,"_153":-5,"_224":228,"_98":229},{"_20":139,"_13":140,"_141":142,"_143":-5,"_144":21,"_145":30,"_146":52,"_22":223,"_29":56,"_148":149,"_150":151,"_152":40,"_153":-5,"_224":225,"_98":226},["D",1783374254049],"children",[],[140],["D",1783374254049],[],[156],["D",1783374254049],[],[163],["D",1783374254049],[],[169],["D",1783374254049],[],[175],["D",1783374254049],[],[181],["D",1783374254049],[],[187],["D",1783374254049],[],[193],["D",1783374254049],[],[199],["D",1783374254049],["D",1789523429989],{"_11":12,"_96":92},{"_11":12,"_89":90,"_91":92,"_47":48,"_93":94,"_95":40},{"_29":30,"_13":26,"_20":21,"_27":28,"_31":32,"_33":34,"_82":42,"_83":84,"_85":86,"_87":14,"_88":12},"ctx",{"_75":-5,"_120":289,"_290":291,"_292":293,"_294":40,"_295":40,"_296":40,"_297":52,"_298":-5,"_299":-7,"_300":-7,"_301":56,"_302":40,"_303":40,"_304":-5,"_305":40,"_306":40,"_307":40,"_308":-5},"ENV",{"_260":261,"_262":263,"_264":26,"_265":266,"_267":268,"_269":270,"_271":272,"_273":274,"_275":276,"_277":278,"_279":280,"_281":282,"_283":284,"_285":286,"_287":288},"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"]
