Use Case
Improve Developer Writing in Seconds
RewriteBar is a macOS menu bar app that rewrites selected text. Use it in VS Code, Cursor, terminal, or Slack to clean up commit messages, format SQL, explain code, and summarize long logs.
25 MB • Mac Intel & Apple Silicon • macOS 13.0 (Ventura) or later.

Sound Familiar?
Common writing bottlenecks this solves
Commits and PR descriptions are often rushed
One-line commits and unclear PR text slow reviews. You need clearer writing without opening another tool.
Raw SQL and logs are hard to scan
Dense queries and long stack traces hide key issues. You want quick formatting and summaries for faster debugging.
Docs and comments need polish
Your implementation is done, but the explanation is rough. You need cleaner technical writing before sharing.
How It Works
A simple flow to get better results
Select text in your app
Highlight a commit message, PR section, SQL query, log block, or doc snippet in your current app.
Run a RewriteBar command
Trigger RewriteBar and choose a command like Format SQL, Explain This, Summarize, or Improve Writing.
Paste and keep going
Paste the output back into your IDE, PR, doc, or chat and continue working.
Before & After
Real rewrites you can apply in seconds
Before
fix bug in auth
After
Fix null reference in auth flow when session expires. Add a guard in validateSession() and return HTTP 401 with a clear error message.
Before
SELECT * FROM users WHERE id=1 AND active=true ORDER BY created_at DESC
After
SELECT * FROM users WHERE id = 1 AND active = true ORDER BY created_at DESC
Before
const re = /^[a-z]+@[a-z]+\.[a-z]+$/i
After
This regex validates a simple email format: letters before and after "@", then a domain suffix. It is case-insensitive because of the i flag.
