Bob gets a GPT brain transplant

What it does

This plugin drops an LLM engine into Bob, a macOS translation and OCR app. It sends text to the OpenAI API and returns translations, sentence polish, or grammar fixes. Set the target language equal to the source and it switches to editing mode, pitched in the README as a Grammarly replacement for any language.

The interesting bit

The author cheerfully admits this is just a small Bob plugin and that the real power is Bob itself. That humility is rare in a repo whose description declares the Tower of Babel obsolete.

Key highlights

• macOS-only; requires Bob v0.50+ and an OpenAI API key
• Handles translation, polishing, and grammar correction in one package
• Polishing is advertised as working for any language, not just English
• A dedicated sibling plugin exists if you want advanced polishing with change explanations
• Licensed under CC BY-NC-SA 4.0 (non-commercial)

Caveats

• Tied to macOS; the author explicitly redirects Windows and Linux users to a browser extension
• Requires a valid OpenAI API key and calls out to OpenAI’s servers
• The non-commercial license may block workplace or commercial use

Verdict

Grab it if you are already a Bob user on macOS and want GPT smarts inside your existing workflow. Everyone else should look at the author’s browser extension or wait for Bob to port elsewhere.
