Every language,
on your terms.

Run any AI model you like — a frontier one in the cloud, or your own running locally via Ollama. 112 languages, translated exactly how you decide, with keys that never leave your Mac.

Say it in every language.

Pick a phrase — watch it land in a dozen tongues at once.

Any model,
your choice.

Revayo never locks you to one engine. Provider and model are just two fields — swap them whenever you like and keep translating without missing a beat.

  • Switch models in a click. Trade OpenAI for Claude, or a frontier model for a tiny fast one — mid-sentence, no restart.
  • Cloud or on your Mac. A hosted model when you want power, or a private one via Ollama when you want it to stay home.
  • Your keys, your rules. A key per provider in the Keychain, no account, no lock-in. Tweak the prompt too, if you feel like it.

A key is remembered for each provider — flip between them freely.

Small window. Whole world.

112 languages, sorted for you

From Arabic to Zulu. The ones you actually use float to a Frequent section up top — the app learns from every translation.

Bring your own AI

OpenRouter, OpenAI, Claude, a local Ollama model — or any OpenAI-compatible endpoint. Kimi, DeepSeek, your call.

Private by design

API keys live in the macOS Keychain, one per provider. Nothing sits in a plist. Your text goes only where you point it.

Swap in a keystroke

Flip source and target — and the text along with them — in one click, then carry the conversation back the other way.

Streams as it thinks

Auto-detect the source, translate on ⌘↩ or as you type. Watch the answer arrive word by word.

Know what it costs

Every translation logs prompt and completion tokens — plus the dollar cost when your provider reports it. History keeps the last hundred a click away.

Bring your own intelligence.

A frontier cloud model when you want the best, a private model on your own machine when you want it to stay there. Same window, your choice — every time.
