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

1

Select text in your app

Highlight a commit message, PR section, SQL query, log block, or doc snippet in your current app.

2

Run a RewriteBar command

Trigger RewriteBar and choose a command like Format SQL, Explain This, Summarize, or Improve Writing.

3

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

Commit message

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.

SQL

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

Explain code

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.
