### 5/5 — Super handy for quick notes

*2026-04-29*

Super handy for dictation. I like that it’s flexible — you can see the words come in as a stream, in batches, or even as bullets depending on how you want to capture thoughts. Makes long messages and quick notes much easier.

### 5/5 — Exceptional

*2026-04-07*

Didn’t expect to love this this much. I just talk normally and it gets almost everything right—even punctuation. Super fast, super easy, and I barely type anymore. Definitely worth it.

### 5/5 — Finally, voice input that doesn't make me switch keyboards

*2026-04-07*

I've tried Apple dictation, and it's fine — until it makes a mistake. Then I have to switch to the regular keyboard, find the error, fix it, switch back. Echo keeps everything in one keyboard. Speak, fix, send. Game changer for messaging.

### 5/5 — Very efficient tool

*2026-04-04*

Very effective tool with lots of customization. Best voice input method ever!

### 5/5 — Super fast and accurate in streaming mode

*2026-04-04*

very smooth and Intelligent. The speed is extremely fast with the stream mode.
