LINE Voice Dictation

One app, every conversation. Aqua keeps you moving.

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

Write where you work

Line handles everything from casual conversations to business messaging and group chats, but typing across all of them takes effort. With Aqua, you hold a key and speak. Your words appear in the message box, formatted and ready to send, at up to 230 words per minute. No setup required and no interruption to your workflow.

Aqua reads the context of your screen so it understands the nature of the conversation you are in. It shifts your tone naturally: relaxed and friendly in personal chats, cleaner and more considered in business or group threads. Add names, sticker phrases, and the language you use regularly to your custom dictionary so Aqua always gets it right.

@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
