Family sharing

Everyone who cares for your baby, in one journal

Parents, grandparents, and the nanny each get their own login and join your journal with a family code. Whoever has the baby logs the feed, and everyone else can see it.

Use with AI

Log and check in from your AI chat

Already ask an AI chat for help with the baby? Connect it to your journal, then just ask it to log a bottle or tell you how naps went this week. No need to open another app.

Connect your AI

ChatGPT and Claude can connect with a tataya sign-in where custom connectors are available. Muse can use an agent key. Everything also works in your browser.

Message for your AI

I'm new to tataya. Help me connect it to this AI client and get started with my baby's activity journal.

1. Read the official setup guide first.
   - Guide: https://tataya.co/developers
   - API specification: https://tataya.co/openapi.json
   - Web app: https://app.tataya.co/
   - tataya tracks sleep, milk, solids, and diapers in a shared family journal. It supports English and Chinese and local timezone display.
   - tataya has a hosted remote MCP connector at https://app.tataya.co/mcp. Setup guide: https://tataya.co/connect. It also has a REST API and Node.js CLI. Do not assume there is a marketplace listing or onboarding skill. Do not invent tools or endpoints.

2. Check what this client can do.
   - Prefer the hosted MCP connector for ChatGPT, Claude or another remote MCP client with OAuth. Help me add https://app.tataya.co/mcp as a custom connector, choose OAuth with automatic client registration, then sign in to tataya in my browser. I can create an account during that flow. Choose read-only unless I ask to log care. Access refreshes automatically and I can disconnect it in Settings. Never ask me for a token or password in chat.
   - If MCP is connected, verify it with get_journal and list_activities using limit 1, without adding any care. Then skip API-key setup below. If custom connectors are unavailable on my plan or client, explain that and offer the web app or agent-key alternative.
   - If it can run terminal commands, help me use the official CLI linked in the guide. Inspect the downloaded source before executing it; Node.js 22 or newer is required.
   - If it can make authenticated HTTP requests, use the documented API and its secure credential storage.
   - If neither is available, explain the limitation and guide me to a supported execution environment. Do not claim the connection is working until you have verified it.

3. Help me authorize access.
   - Guide me to sign in or create an account in the web app and set up or join my family journal.
   - Guide me to Settings → Agents & API → Connect your AI → Use an agent key. Use the three-step setup to create a durable agent key, save it in this client's private credential field, and copy the connection message. If I already saved a key, use Use saved key instead of creating another. Agent keys start with ttk_, have no automatic expiry and can be revoked in Settings. Never ask me to paste a key into chat.
   - Use https://app.tataya.co/api/v1 for HTTP requests; send one Authorization: Bearer prefix around the saved raw key. Do not send it to Supabase Auth. For the official CLI, TATAYA_URL=https://app.tataya.co and TATAYA_TOKEN contains only the raw key. A refreshable CLI login with --password-stdin in a private terminal is an alternative; it is not needed when an agent key is configured.
   - Keep passwords, agent keys, access tokens, refresh tokens, and family share codes out of this chat, prompts, source files, and logs. Never ask me to paste credentials into a message.
   - Explain that an agent key is limited to one family and can be read-only or read-and-log. A caregiver CLI sign-in session inherits my account permissions instead.

4. Verify the connection with a read-only request.
   - Use the CLI whoami command or GET /api/v1/me, then read GET /api/v1/events?limit=1. Use only IDs returned by tataya.
   - Confirm that authentication and family access work without printing credentials or unnecessary personal information.
   - If a request fails, report the HTTP status, error.code and request_id without credentials. Check the saved key and API address before asking me to sign in again. If family access fails, help me check my family setup. Read the actual error and guide instead of guessing that a durable key expired.

5. Help me see my first journal entries.
   - Ask which timezone and period I want to view, defaulting to today in my local timezone once confirmed.
   - Use events list or GET /api/v1/events with explicit since/until timestamps including Z or a UTC offset. Follow next_cursor with the same time bounds until all requested entries are read.
   - Summarize the actual entries in my chosen timezone. If the journal is empty, say so; do not create demonstration records in my family's journal.

6. Offer my next step.
   - Ask whether I'd like to log a real activity or review recent care. Before writing, confirm the activity details, time, and timezone from my request.
   - Use a stable Idempotency-Key for each intended new activity and reuse it if retrying. Do not overwrite a completed sleep session or invent an activity from a sleep suggestion.
   - After a write, check the returned result and tell me what was recorded. Sleep suggestions are planning aids, not medical advice.

Start by reading the guide and checking this client's capabilities.

A few things to know

What is tataya?

tataya is a free shared baby journal for parents, grandparents, and other caregivers. Log sleep, milk, solid foods, and diapers together, with nap and bedtime suggestions based on your baby's age and logged sleep.

Is tataya free?

Yes. Creating a journal, inviting family, and nap and bedtime suggestions are all included, with no subscription and no trial that ends.

Do I need to download an app?

No. Use tataya in the browser on your phone or computer. Add it to your home screen if you want it one tap away.

How are nap times suggested?

They use your baby's age and logged sleep, including recent wake times and nap lengths. Suggestions update as you log sleep. They are a planning aid, not medical advice or a diagnosis.

Which AI chats can connect?

ChatGPT and Claude can connect with a tataya sign-in where custom connectors are available. Follow the AI connection guide. Muse and other agents can use a lasting key through our API or CLI. Your AI plan or workspace may limit custom connections.

What can I log?

Sleep, milk feeds and amounts, solid foods, and diaper changes. You can look back by day, by week, or as a list.

Does it work in Chinese, or when we travel?

Yes. The app works in English and Chinese, and entries are shown in the timezone you choose, so the day still lines up when family lives apart or you travel.

Is our journal private?

Yes. Your journal requires sign-in, and public pages never show family activity. If you connect an AI chat, choose read-only or read-and-log access and disconnect it in Settings whenever you want. If your agent uses a key, keep the key private and revoke it when you want access to stop.
