What users praise

Who should pick Bob, and who should pick Gemini?
- Google Workspace power userPick: Gemini
Gemini is the only one of the two that actually reads Gmail, Docs, and Calendar and pulls live Search results into drafts.
- Researcher or translator reading foreign PDFs and contracts on a MacPick: Bob
Select-text and screenshot translation in any app, with 30+ engines and multi-engine side-by-side comparison, is exactly the workflow Bob was built for.
- Developer scripting GUI automationPick: Gemini
Computer-use actions plus the Gemini API let you script click/type/navigate flows; Bob has no automation layer at all.
- Anyone who needs text pulled out of an image offlinePick: Bob
Bob's offline OCR, silent screenshot OCR, Finder image OCR, and continuous recognition with smart paragraphing are the specific tools for that job.
- Non-Mac userPick: Gemini
Bob ships macOS only, so if you're on Windows, Linux, or Android, Gemini is the only option on this page that exists for you.
Frequently Asked Questions
Can Bob do the things Gemini does with Gmail, Docs, and Calendar?
No. Bob has no Google Workspace integrations, no Search grounding, and no generative drafting — it converts and translates text you point it at, and stops there.
Can Gemini replace Bob for translating what's on my screen?
Not the same way. Gemini handles image and audio input and can be scripted through computer-use actions, but Bob's whole design is instant in-app capture on macOS — select-text, screenshot region, or Finder file — without leaving the window you're working in.
Do I need to pay for Bob's translation engines?
Most of them, yes, indirectly. The app is a free download, but you apply for and supply your own API keys for providers like DeepL, Google, Microsoft, and the Chinese engines, and those providers bill you for usage. Offline OCR and the built-in dictionary don't add a bill.
What changed in Bob 1.20.0?
It added standalone OCR mode — using OCR without running the translation pipeline — and original-image translation, which routes image content into translation through an OCR plugin.
Does Gemini work on a Mac the way Bob does?
Gemini is reachable on the web, Android, Chrome, Google Home, and via API, and it's a general assistant rather than a menu-bar utility. If you specifically want OS-level in-app translate/OCR on macOS, that is Bob's niche, not Gemini's.
Is Bob useful for a team with a shared glossary and review workflow?
No. Bob explicitly doesn't do collaboration, shared term bases, or review pipelines — it's positioned as a personal productivity tool for individual users.
