Lembic Reviews — Discover what people think of this product.

Lembic takes a different path. It reads the Messages history already synced to your Mac and turns any thread, whole or by date range, into a token-efficient transcript an AI can actually read, handling reactions, timestamps, and attachments cleanly instead of dumping noise.

One click copies the conversation, or the conversation plus a ready-made prompt, so you can paste it straight into your own ChatGPT, Claude, or Gemini account and ask. Because these are your most personal conversations, safety is built in: Lembic flags passwords, account numbers, and one-time codes as you read, so you can redact them before anything leaves your Mac, and you stay the final reviewer. Nothing is ever uploaded, because there is no server and no account; the export engine is open source, and Lembic is a one-time purchase, not a subscription.
