- Customize formulas, assets, and components down to the engine.
- Use one integration for six office tools, composed and embedded freely.
Office tools, one runtime
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. The Spreadsheet SDK uses a spreadsheet-specific OT collaboration algorithm with conflict handling, history, and support for 200 simultaneous editors.
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 Rust-based formula runtime with 500+ built-in functions calculates one million formulas in seconds. Web rendering of 10 million cells with smooth scrolling. PivotTable aggregation of one million rows in milliseconds.
