What people say about Echoo.
Read their feedback, or see Echoo featured in VVMac Magazine (opens in new tab).
It is exactly what an AI assistant should be, with the minimum interface necessary and very transparent, I just wrote an article on it in VVMac Magazine.
I've tried many tools claiming to do something similar, but none are even remotely as intuitive and user-friendly.
Love it!
See how it works.
Watch Echoo turn a Spanish draft into clear, natural English in Gmail, then rewrite it to sound like you. One shortcut. No copy-paste.
Music and interface sound effects only; no spoken narration.
- Write in your own language: a Spanish reply is typed in Gmail.
- One shortcut, Option+E, turns it into clear, natural English in place. No copy-paste.
- Tell Echoo about you once: in Personalization you add what you do, who you write for, and how you like to write.
- Same draft, now it sounds like you: Option+R rewrites it in your voice. Rewrite, To English and Translate all use your profile.
- In Slack, Screen Context lets Echoo see the message you are replying to, so the reply names Priya, the Q3 report and the 2pm deadline.
- On LinkedIn, Memory learns your names and terms, so Echoo is spelled right the next time.
- Edit any command’s system prompt and shortcut, and use it in any app: Gmail, Slack, LinkedIn, Docs and your IDE.
- The video ends with: Don’t translate. Just write. Download free for Mac, 10 free credits, no credit card.

Straight from your Mac to the AI provider’s API, on every plan. For the free credits and paid plans, Echoo issues a dedicated API key for your account and the app calls the provider directly with it; your text never passes through Echoo’s servers, which only receive usage counts. Optional Memory keeps command history with the AI provider until reset or its size limit. Memory is off by default.
Move Echoo to Applications, open it, and allow Accessibility access so it can read and replace text. Requires macOS 14 or later.
Most Mac apps, including Slack, Mail, Notion, and Gmail in your browser. Text fields must support macOS Accessibility; some apps and fields do not.
