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.

THREE CLICKS, START TO FINISH
1

Pick a conversation

Lembic reads Messages on your Mac and lists every thread by contact name.

2

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.

3

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.
