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 rewrite a Slack reply and an email without switching apps.
Music and interface sound effects only; no spoken narration.
- Echoo introduces writing shortcuts that work inside your current app.
- A Slack reply and an email draft are transformed in place, without copying text into a separate chat.
- A comparison shows switching between apps versus invoking Echoo with a shortcut. Local models keep text on your Mac; BYOK sends it to your provider; managed AI uses Echoo’s OpenAI project.
- Command settings show an editable prompt and shortcut. Screen Context attaches a screenshot to help the AI understand a Slack conversation.
- The video ends with the free trial and plan options. Your first 10 credits need no API key or card.
