Hold a key. Speak your thoughts. Keep your flow.

Aqua works in every Superhuman compose window and understands the context of the thread you are replying to.

@0xferruccio

For coding prompting with voice nothing beats @aquavoice All the other transcription apps don't work well with code like tailwind class names

@chiggyAI

just tried out @aquavoice and by far the most accurate voice to text tool i've used!!

@TheNathanRuff

Been using @aquavoice for a few months. Unbelievably better than the other companies that do this

@jamesfong

3 products that have broken into my forever home. And that's not an easy feat for me: @circlebackai, @aquavoice, and @superset_sh

@tzmartin

tbh @aquavoice is a vibe coder's delight.. lowest latency, highest quality STT I've used so far

@juanbuis

this is why @aquavoice is better than all other AI transcription apps it actually writes like you talk

@heyvyner

Mapping @aquavoice to this button on my mouse is a whole different level of productivity.

@nozmen

Aqua Voice: I barely type long prompts now, just talk. Saved ~5 hrs typing in 2 weeks. Much more accurate than macOS dictation.

@gkossakowski

Aqua is a true power tool: quick, reliable and understands your context - they were early at appreciating the value of context engineering.

@jackson_felty

@aquavoice is a prime example of how much better a product can be when the team focuses on making one simple use case incredible

@ArtemR

Aqua Voice @aquavoice is the voice-based text editor I think all of us have always wanted, but no company has been able to deliver so far. The demo is extremely impressive

@jaymehoffman

@aquavoice has saved me over 2 days of typing

@thebuildguy

Unpaid shout out — @aquavoice is probably one of my most used tool that has saved me quite literally a day of time!

@Memetic_Theory

If you're not using @aquavoice you're moving 15% slower than you could

@rickmanelius

Impressed with @aquavoice accuracy in a noisy airport.

@turboblitzzz

Started using @aquavoice a few weeks ago and now I barely type anything. My housemates want to kick me out because i keep talking to my computer. Life is good.
