Office tools, one runtime

Six tools, one runtime — sharing the same storage and computation, composing and embedding freely
Agents work across every file type — without losing context
Data stays synchronized — sources change, references update

Univer

Not one tool — the whole runtime. Sheets, docs, slides, and canvases live in one .univer file, composing and embedding freely, with humans and agents working side by side.

  • Every block in one place — a slide holds a live sheet, a doc cites its source, a canvas lays it all out
  • Data stays synchronized across every block — sources change, references update
  • Humans and agents co-edit in the same file, every change traceable

Core Features

Full details in the capability matrix.

One Runtime for Every Office Tool

Spreadsheets, docs, slides, canvases, relational tables, and more — on a single runtime. Data stays connected and traceable: a doc references a sheet; the source changes, everything synchronizes.

Human–Agent Co-Editing

Humans and agents edit the same file at the same time. Review, refine, or directly modify agent-produced work — at any point in the workflow.

Multi-Agent Workflows on Worktrees

Run multiple agents on the same file simultaneously — each on its own isolated worktree. Humans review and merge every contribution.

Git-Style Version History

Every change is tracked and reviewable. Restore any version, merge with control.

Agent Self-Verification

Agents set their own validation conditions, test their output, and iterate until requirements are met — before handing it back.

High-Fidelity Import & Export

High-fidelity import and export for XLSX, DOCX, PPTX, CSV, TSV, PDF, and more. See the full format list under Capabilities.

Self-Hosted by Design

Deploy on your own infrastructure. No third-party accounts, no data leaving your environment.

Embed Anywhere

White-label, no watermark. Customizable themes, feature trimming, i18n, and open NPM packages.

Excel-Grade Performance

A formula engine with 500+ formulas and execution — computation speed on par with Excel, capacity up to 10M cells. Changeset sync — collaborators get the diff, not the file. Less to transfer, faster to sync.
