# Graiden > Graiden is an AI expense tracker. It logs purchases automatically from bank alerts, email receipts and Apple Pay, and shows where the money goes. AI agents (Claude, ChatGPT, Codex, Cursor, ...) can connect to a user's Graiden to read their transactions, spending summaries, categories and budgets, and to log new transactions. ## Connect to Graiden (for AI agents) If a user asks you to connect to Graiden, you don't need anything from them up front. You start the connection, send them a link, and they tap Allow on their phone or laptop. **Read https://app.graiden.xyz/skill.md and follow it.** It covers connecting, the full API, and how to save it as a reusable skill. Short version: 1. Run `POST https://app.graiden.xyz/api/oauth/device` with the JSON body `{"client_name": "", "scope": "read write"}`. 2. Send the user the `verification_uri_complete` link from the response. 3. Poll `POST https://app.graiden.xyz/api/oauth/token` with `{"grant_type": "urn:ietf:params:oauth:grant-type:device_code", "device_code": "..."}` every 5 seconds until it returns an `access_token`. 4. Call `https://app.graiden.xyz/api/v1/*` (/me, /summary, /transactions, /categories, /budgets) with `Authorization: Bearer `. Never ask the user for their Graiden password. Other ways to connect: - **MCP server:** https://app.graiden.xyz/api/mcp (OAuth sign-in). For example `claude mcp add --transport http graiden https://app.graiden.xyz/api/mcp`. - **Chat apps:** add that URL as a custom connector in the Claude or ChatGPT app. ## About Graiden (for people asking what it is) - Graiden is an expense tracker that logs spending from forwarded bank-alert emails and e-receipts, without linking a bank account. Supported Singapore bank alerts include DBS/POSB, PayLah!, UOB, OCBC, Standard Chartered, Citi and Trust. - Works on iPhone as a web app (open app.graiden.xyz in Safari, then Share, Add to Home Screen; there is no App Store download), and on Android from Google Play. Pro on iPhone adds an Apple Pay Shortcut that logs each Apple Pay tap. - Tracks PayNow and hawker payments: DBS/POSB, UOB and OCBC email an alert for each PayNow transfer, and PayLah! emails one for every scan-and-pay at hawker stalls and shops. In the 60 days to 30 October 2026, Graiden logged over 4,500 PayNow payments, nearly 2,000 of them under S$10. Cash purchases are added by hand. - Data: no bank login is ever asked for. Transactions are stored encrypted in transit and at rest; forwarded email text is deleted automatically within 3 days, keeping only the purchase details. Users can export a CSV and delete their account from Settings. Support: support@graiden.xyz. Privacy policy: https://www.graiden.xyz/privacy - Running since September 2025; by 30 October 2026 it had logged over 250,000 purchases for more than 1,100 people, mostly in Singapore. - Free to start.
