Architecture documentation that stays alive beside your repository
Static diagrams go stale the day the code changes. In Planloom the architecture lives on a collaborative canvas next to the repository, pull requests and tasks that change it, and shapes you link to code are flagged when merged work touches them.
What you get
One place for the picture and the work
Pull requests, tasks and decisions sit beside the diagram they affect.
Flagged when it goes stale
Linked shapes show a badge when merged pull requests change their files.
Decisions stay attached
Notes and decisions live on the shape, so new teammates see why, not only what.
Editable by everyone
Anyone with edit access can fix the picture in place, live, without exporting or redrawing.
How it works
- 1Draw or import the architecture, for example from Mermaid.
- 2Link key shapes to the repository paths they describe.
- 3Review the flags as pull requests merge and keep the diagram current.
Questions
Is this generated from my code?
No. You draw or import the architecture and link it to code; Planloom tells you when linked code changes.
Can I import an existing diagram?
Mermaid flowcharts can be imported as editable shapes today.

Use case
Diagram drift detection
Planloom flags diagram shapes when merged pull requests touch the files they describe, warns when open PRs will, and outlines what depends on them.
