| What it is | Open-source SDK to build office apps (sheets, docs, slides) inside your product | React component (@doconda/editor) with ready-made Word, PowerPoint, Excel and PDF editors |
| Working format | Its own data model (JSON) | The files as they are: .docx, .pptx, .xlsx and .pdf |
| Opening and saving Office files | Importing and exporting .xlsx needs Univer Pro and a conversion service on a server; .docx is not among the import/export formats | Directly in the browser, no server; whatever the editor does not touch is saved as it was |
| PDF | Not an editing format | Fill in forms, sign, annotate, comment and organize pages |
| Server | Not needed to edit its model; needed to import and export Office files | None |
| React | Its UI is built with React (18 and 19) | React 19 or later |
| Collaboration | Real-time co-editing in Univer Pro | One person edits their copy and you decide where to save (onSave, autosave) |
| AI assistant | Built for agents: with Univer Platform spreadsheets are driven in natural language | Built into Word, Excel and PowerPoint: the user asks for changes in plain language, sees them made and accepts or discards them; no API keys, 2,000 edits a month on every plan |
| Licence | Apache-2.0 core; commercial Univer Pro (collaboration, import/export, printing, charts, pivot tables…) | Per organization: monthly, yearly or one-time, 7 days free; unlimited documents and users, up to 5 domains |
