What you get

Five ways your archive works for you.

A handful of chats, you can track yourself. Hundreds, you can't — the work, the ideas, the threads all scatter. Archessa holds it all and organizes it for you, on your machine.

01 · Work recovered

See every output, directly.

1,306 deliverables were buried across 633 chats. Your gallery lays them out like a doc drive — documents as readable pages, website designs as little rendered windows, data as tables — scroll, and it's all just there.

Who it's for

If you use AI a lot, this is for you.

Archessa reads your history through whichever lens fits how you work — and everyday chatters are just as welcome as power users.

🔨

Builders

The code and prototypes you shipped inside chats, recovered as real files.

✍️

Writers

Your drafts, characters, and the story decisions you worked out — all kept.

🔎

Researchers

Sources and findings across dozens of chats, searchable and cited.

📚

Learners

Study conversations turned into notes and flashcards you'll actually review.

💼

Professionals

The recurring answers and templates you keep re-asking, deduped and to hand.

🌿

Everyday users

Recipes, trips, advice, decisions — the everyday stuff, findable again.

Archessa picks your lens automatically — and you can switch it any time.
How it works

Three steps, about five minutes.

Export your history

One click in ChatGPT (Data controls) or Claude (Privacy). They email you a .zip.

Drop it into Archessa

Drag the file in. It's read and organized on your machine — nothing is uploaded.

It all comes together

Sorted into projects, searchable, your work recovered, insights synthesized.

Private by design

It all happens on your computer. Your chats never leave your machine.

No sign-up, no server, no upload — it all runs on your own laptop, so we never see your chats, and couldn't if we tried.
