AI Integration

BabyLog doesn't have a built-in AI assistant. That's intentional. Instead, the Ask AI modal lets you build a structured prompt from your baby's logs and copy it into whichever AI you already trust — ChatGPT, Claude, Gemini, Grok, or any other.

The whole flow is designed to be visible: nothing leaves your device until you tap Copy prompt, and you can see exactly what's about to be copied before you do.

For the longer write-up of why we built it this way, see How baby tracker apps can work with AI.

Opening Ask AI

On the Logs page, tap the Ask AI button. The modal opens with whatever you currently have filtered (date range and log types) already loaded as context.

The Ask AI modal showing four context toggles, a response-language dropdown, quick-question chips, and Copy prompt / Open in AI platform buttons. — The Ask AI modal — see what context will be copied, toggle anything off, pick a question and reply language, then copy or open.

Choosing what to include

The Prompt context section has four toggles. Turn off anything you don't want to share:

Baby basic information — name and birthday, so the AI can reason about age.
Logs of current page — whatever you have filtered (e.g. "past 30 days · all log types").
Daily summary rollups — per-day totals (bottle ml, sleep minutes, nappy counts).
Detailed log rows — exact times, amounts and free-text notes.

What you see in the modal is exactly what gets copied. If you toggle Detailed log rows off, the prompt drops to summary rollups only. If you toggle Baby basic information off, even the name and age go away.

Picking a question and reply language

Under Your question, tap one of the quick-question chips:

General analysis · Sleep patterns · Sleep through the night · Feeding patterns · Poo & wee patterns · Weekly summary · Nanny handoff note

Or tap Your question to type your own.

Use the Response language dropdown to ask the AI to reply in a specific language — useful when a non-English-speaking grandparent or carer is the one reading the answer.

Copy or open in an AI platform

Once the prompt is set up, choose:

Copy prompt — copies the full structured prompt to your clipboard so you can paste it anywhere.
Open in AI platform — opens your chosen AI assistant (ChatGPT, Claude, Gemini, Grok) ready to paste.

When BabyLog is installed as a home screen app, Open in AI platform may not reliably hand off — copy-paste is the most dependable path on a standalone PWA.

What the prompt looks like

The copied prompt is plain structured text — readable by both you and an AI. With everything toggled on, it includes:

A short header with your baby's first name and age
The time range you have filtered
Daily summary rollups (e.g. 2026-04-10 · 1004 ml feeds · 11h 30m sleep · 5 nappies)
Detailed log rows for each day (e.g. 6:34 am Wee · 8:30 am Poo · 5:54 pm Solids — Loved 米饼)
A short compression note if your range is longer than fits in one message
Your question, after a --- separator

The Ask AI prompt pasted into ChatGPT — structured day-by-day rows, a compression note, and a clear "User request" line. Paste straight into ChatGPT, Claude, Gemini, Grok or any AI you already use. The prompt is plain text, so the AI can understand the context immediately.

If your range is large, BabyLog compresses intelligently — older days drop to daily rollups first, then notes, while keeping the most useful recent detail.

Example reply

Because the AI sees a calm, structured prompt, the reply usually comes back the same way — organised by category and easy to skim.

A structured ChatGPT reply covering Big Picture, Feeding Patterns, Sleep Patterns, and Nappies & Digestion based on the pasted logs. A real reply from ChatGPT, organised by category.

You can ask follow-ups in the same chat — "what should I bring up at the maternal health nurse?", "compare this week to last week", "rewrite this as a handoff note for our nanny."

Privacy note

Privacy in Ask AI is visible, not just claimed:

The modal shows the toggles and the prompt preview. Nothing is hidden.
Nothing is sent automatically — you toggle, you tap, you paste.
BabyLog has no backend connection to any AI service. The prompt travels via your clipboard, the same way you'd copy and paste anything else.
Once you send the prompt to a third-party AI, it is processed by their servers under their privacy policy. Use a provider you trust and review their terms; some platforms let you control whether your chats are used for training.
