Your AI can read documents. Now let it work on them.
Meet Leela Workbench. A local-first workspace where AI agents work directly with Word documents, PDFs and everything around them.

For Mac with Apple Silicon. Windows is coming soon.
Open a folder. Fire up Claude Code or Codex. Give your agent the tools to inspect documents, compare versions, make tracked changes and work across entire document packages. Watch the work happen, review the results and stay in control.
Your files. Your agents. Your rules.
Open a folder to see its documents here.
Start a session with the + button.
Put your agents to work.
Not another place to chat with AI. A place to get actual work done.
Negotiate a contract
Open an MSA and ask Claude to review it against your playbook. Identify deviations, explain the risks and propose tracked changes. Review every change in the document itself.
Understand an entire document package
Point your agent at a folder containing an MSA, DPA, security schedule and supporting documents. Ask it to check for inconsistencies, conflicting provisions, missing information and dependencies across the package.
Compare negotiation rounds
Ask your agent what changed between the last draft and the counterparty's latest version. Separate substantive changes from formatting. Find the concessions, new risks and unresolved issues.
Work through hundreds of documents
Use your agent to inspect a folder, extract specific provisions, compare clauses, identify anomalies and produce structured reports. Run scripts and repeat workflows without manually opening every file.
Create and edit real Word documents
Ask your agent to draft a memo, restructure an agreement, repair formatting or update a document. See the resulting changes in a proper document viewer, not a block of generated text.
Build your own document workflows
Write scripts, create custom tools and connect your own agents. The document operations are available through MCP, so you're not tied to one AI provider or framework.
Your agent gets a workspace. Not just a chat window.
Documents deserve better than a text preview.
Open Word documents as paginated pages. Navigate the outline. Inspect tracked changes as Word displays them. Open PDFs alongside your Word files.
A real terminal, not a simulation.
Run Claude Code and Codex in their native environments, signed in with your own accounts. Open multiple sessions, each working in its own matter folder.
Agents that can actually edit Word.
Workbench gives agents document tools that understand Word structure. They can read documents clause by clause and write genuine tracked changes into a separate copy. Your original stays untouched.
See what the agent sees. Review what it changes.
Keep the document and agent side by side. Follow the work, inspect the output and decide what to keep.
Give your agent our superpowers.
Your agent can already think, write and reason. Give it the tools to work with real documents, manipulate Word files, create tracked changes and tackle complex contract workflows.
Bring Claude. Bring Codex. Bring your own agent. Or use Leela.
Document superpowers
Parse, render, compare and redline Word documents.
Legal superpowers
Give agents Leela's specialist skills and contract intelligence.
Workflow superpowersComing soon
Connect to Leela's contract capabilities through its plugin.
Developer superpowers
Build your own tools and workflows on our open-source libraries.
You choose the agent. You choose the tools. You decide how much of Leela you want in the mix.
Local by design. Yours by choice.
Your documents stay in folders on your computer. Workbench doesn't require you to upload your workspace to a proprietary cloud.
Use your own installed agents and their existing authentication. Choose which tools they can access. Review changes before they reach your original documents.
Your AI provider's own data-handling policies still apply to information you send through its agent.
Built on open document infrastructure.
Workbench is also a showcase for the document technology we're opening up.
DOCX manipulation. Document rendering. Redlining. Comparison. Structured document access.
We're building tools that let software and AI agents work with documents as documents, not just blobs of extracted text.
Explore the libraries. Build something with them. Make them better.
Leela Workbench
A better place for humans and agents to work with documents.
For Mac with Apple Silicon. Windows is coming soon.
You need Claude Code or Codex installed. Workbench finds it on its own. Working in a dedicated client workspace? Your workspace builds are under Account, then Desktop apps, once you sign in.
