Export your iMessages into something AI can actually read
Turn any conversation into a clean, compact file for ChatGPT, Claude, Gemini, etc., then ask it anything. Your texts never leave your Mac.
[2024-03-14 18:02] Mom: are you still coming sunday?
[2024-03-14 18:05] Me: yes, bringing the pie
[2024-03-14 18:06] Mom: perfect, your sister's in too
[2024-03-14 18:09] Me: should I grab anything else?
[2024-03-14 18:11] Mom: just bring yourself

You're sitting on years of conversations. The one thing you can't do is ask about them.
Apple gives you no real way to get your messages out. The tools that exist were built for other jobs:
PDF exporters
Built for lawyers and scrapbooks. They're bloated, full of UI noise, and they blow past an AI's context limit the moment you paste them.
Terminal tools
They work, if you're a programmer who enjoys command-line flags.
"AI analyzer" apps
They read your texts, run their own AI on them, and sell you a report. Your most private conversations, sitting on someone else's server.
Maybe you want to make sense of a difficult relationship, or just find the plan you made last spring. Either way, there's never been a simple, private way to take a thread and hand it to your own AI. Until now.
Pick a conversation
Lembic reads Messages on your Mac and lists every thread by contact name.
Export
It turns Apple's message database into a compact, AI-ready transcript. Reactions, dates, and attachments are handled cleanly, with none of the bloat that eats an AI's context.
Ask
One click copies the thread, or the thread plus a ready-made prompt. Paste it into ChatGPT, Claude, Gemini, etc., and ask.
Made for AI, down to the last token
Everything about the export is tuned for one job: getting a clean, private transcript into the AI you already use.
Built for AI, not for paper
Every other exporter makes a PDF. This makes a token-efficient transcript an AI reads cleanly, so you get better answers and fit far more of the conversation into one chat.
One-click prompts
Comes with prompts you can run in a click: summarize a relationship, trace how someone's tone has shifted over time, build a timeline, or check how your own reply reads before you send it.
Your texts never leave your Mac
There is no server to upload to. The transcript goes straight from your Mac to the AI you pick, on your own account. The engine is open source, so you can check that yourself instead of trusting a claim.
Pay once
A one-time purchase. No subscription on the export app, ever.
Smart about the messy stuff
Reactions, replies, photos, links, and timestamps all get handled: kept when they carry meaning, compacted when they don't.

PRIVACY
The only iMessage exporter that can't read your messages.
We mean that literally. There's no backend. It never connects to a server because there isn't one to connect to. Reading your database and building the transcript both happen on your Mac. When you take that transcript to an AI, you're using your own ChatGPT or Claude account.
And you don't have to take that on faith. The engine that reads your messages is open source, so you can read it or compile it yourself.
It uses the same Full Disk Access permission macOS gives Time Machine and other backup tools. You grant it once, and you can revoke it anytime.
