Capsa

Your AI conversations, kept and understood.

Capsa collects your AI conversations from every tool into one archive you own, and reads the reasoning patterns inside them. The tools delete on their own schedule. Your archive does not.

Test environment

Capsa on the web is a test environment.

You can create a login, upload your chat history, and configure your insights. It is an early build, offered so you can try the archive on your own record. What you upload is yours: you can export everything and delete your account at any time.

Open capsa.hammerai.ai

How it works

Three steps.

01

Create a login

Sign up at capsa.hammerai.ai with Google, GitHub, or an email code. Your archive is private to your account.

02

Upload your chat history

Drop in your ChatGPT export, or connect Claude Code and your coding tools. Every file is banked exactly as your tools wrote it.

03

Configure your insights

Choose what the archive reads back to you: how you use AI, how your reasoning moves, what you keep. Every reading cites your own words.

Getting your history in

Where each tool keeps it, and how to bring it over.

ChatGPT

Your history lives on OpenAI's servers, and you can claim a copy. In ChatGPT: Settings, then Data Controls, then Export Data. Drop the ZIP at capsa.hammerai.ai and it is banked byte for byte.

Claude Code and coding tools

Claude Code writes its records on your machine, then deletes them after about 30 days. A free command line tool saves them into a local vault, banks them in your account, and keeps it automatic:

pip3 install hammer-capsa
capsa
capsa sync
capsa schedule

Yours to keep

The record is yours.

Originals, byte for byte

Every file is kept exactly as your tools wrote it. Nothing is interpreted away, so future uses stay open.

Only you see it

Capsa only ever shows you to yourself. No comparisons to other users, and nothing leaves your machine without a deliberate act by you.

Leave anytime

Export all returns your exact bytes in one click. Delete everything removes your account and every file immediately.

Named for the capsa, the Roman box that kept scrolls safe. The command line tool is free and open. Package: hammer-capsa on PyPI.
