Engineers and business teams, in the same place.
A collection of use cases for teams that want document management and version control on GitHub. An AI-powered online editor with GitHub as the backend.
| Situation | Challenge | With PlainHub |
|---|---|---|
| Documents are getting scattered | Can't tell which version is current, too many management tools | Centralize on GitHub. History is recorded automatically. Ask AI to "find it" |
| You want to own your data | Don't want to depend on a specific service | Stored in standard Git format. Data always lives on GitHub. Migrate anytime |
| Need to edit on the go | No PC, no IDE available | Edit and save with just a browser. Accessible from your phone |
| Want to work alongside AI | AI tools and documents are in separate apps | Built-in AI panel. Consult AI while editing |
| Need to edit large files | Other editors slow down at a few thousand lines | Smooth editing even for files with tens of thousands of lines |
A common pain point for teams: "I want to revert that file" or "Who changed it, and when?"
PlainHub automatically creates a Git commit every time you save, so the following works with zero extra effort:
- Automatic change history — every file change is recorded in Git. "When, who, and what changed" is always traceable
- Restore to any point in time — browse and restore past states from Git history
- Visual diffs — see before-and-after differences at a glance
- No branches needed — non-engineers just save to the main branch and version control is done
Most cloud services offer some form of change history, but Git is a distributed version control system — robust and capable of maintaining history over the long term.
- Review and fix documentation in the browser during code reviews
- Analyze with Claude Code → create reports in PlainHub → commit to the same repo
