You, your Claude, your documents.Working together.
Lorzi connects your Claude to your documents safely. Claude explains what changed; Lorzi shows the exact diffs. Understand AI edits in seconds, not minutes.
Free tier. Premium features coming soon.
Works with any Claude account — free or paid.
The problem
You're copying content into Claude, getting a response, copying it back out. Over and over. It works, but it's tedious.
And when Claude does edit your document directly? It says "Done! I cleaned it up and improved the flow."
But did it also rewrite your opening? Cut that example you needed? Change the tone you spent an hour getting right?
You won't know until you re-read the whole thing. Even Anthropic's own Cowork warns you to "keep separate backups."
There's a better way.
Think Together.
Two windows. Instant understanding.
Lorzi connects your Claude to your documents with a simple workflow:
Chat with Claude
Tell Claude what you need in your project
Claude proposes
Claude explains what it did in natural language
Lorzi shows the diff
Every word added, removed, or modified
One click to apply
Or reject and iterate until it's right
Claude explains the why. Lorzi shows the what. Both at once. You scroll for the red and green, skim the changes in seconds, and know exactly what you're accepting.
Why Lorzi?
AI as a collaborator, not a tool in the sidebar. You and Claude develop ideas together on shared documents.
Nothing changes until you approve
Every AI edit appears as a visual diff before it touches your files. Accept, reject, or ask for revisions. Full history with restore.
See what changed in seconds
Claude summarizes the why in conversation. Lorzi shows the what in diffs. No more re-reading entire documents to find what the AI changed.
Keep your Claude
Uses your existing Claude subscription. Your AI already knows your style, your preferences, how you think. Don't start over with a stranger.
AI that sees your whole project
Every file is automatically in context. Ask questions that span documents. Multi-file changes proposed as a single reviewable unit.
Context that compounds
Stop re-explaining your project every conversation. Your AI remembers decisions from last week, references documents you forgot you wrote. The collaboration builds over time.
AI as collaborator
Chatbots answer questions. Assistants wait for instructions. Agents work alone while you watch. Lorzi is something else: a collaborator who thinks with you on shared documents.
The result
You stop re-explaining your project. You stop hunting through documents for what the AI touched. You start building on yesterday's work instead of starting from scratch.
It's a different way of working.
FAQ

Free tier. Premium features coming soon.
What file types does it support?

How is this different from Claude Cowork?
Cowork gives Claude direct write access — that's why it warns you to "keep separate backups." Lorzi adds a review layer: you see exactly what will change before anything is written.
Do I need a paid Claude subscription?
No. Lorzi works with any Claude account, including free accounts. Free users may hit Claude's message limits during longer sessions, but full functionality works the same.
