Frequently Asked Questions

Kagi vs Rephrase: which should you choose?

If you spend all day typing in macOS apps and want instant grammar/tone fixes without leaving your workflow, Rephrase’s one-time $49.99 is a steal. But if you need a full privacy-first search engine with AI that answers questions from the web, Kagi’s subscription brings way more breadth. They solve different problems: polish vs search. Choose the one that matches your daily bottleneck.

Can Rephrase be used on iOS or Windows?

No. Rephrase is a native macOS app and only works on Apple Silicon Macs. It does not have a web or mobile version.

Does Kagi replace Google entirely?

For general web search, yes. But Kagi does not integrate deeply with Google services like Gmail or Maps. If you rely on those, you may still need Google.

Does Rephrase work offline?

Yes, core features like grammar fix and tone polish run locally with zero latency and work offline. Translation may require an internet connection.

Can I use Kagi's AI Assistant without search?

Yes. The AI Assistant is a separate chat interface that can be used independently, but it's grounded by Kagi search when you query from search results.

Is Kagi Translate now paid only?

Recent news indicates Kagi temporarily disabled free Translate access and will return as a subscription service. So full Translate is for paid subscribers only.

Does Rephrase support custom AI models?

No, Rephrase uses its own local AI models. You can create custom prompts for transformations, but you cannot choose the underlying model.
