Experience of our clients
Really helped me
I was just having a bit of an existential crisis, so I talked about it to Letterly, which provided me with a summary that included very useful category headings. That really helped me figure things out 😍
Transformed how I take notes
It has completely transformed how I take notes! The speech-to-text accuracy is impressive, and the structured output makes organizing my thoughts a breeze. Highly recommend!
2 minutes, and I get a neat email
Usually I’d need around 15 minutes to give a structured feedback but now it’s just 2 minutes of “letterling”, and I get a neat email ready to be sent 🥰
I can let my ideas flow
Letterly is perfect for my forest walks! I can let my ideas flow without stopping. Love it!
Essential tool for content creators
Letterly is amazing. I use it everyday for content. I think it could be an essential tool in the toolkit of content creators, big thinkers, or entrepreneurs.
Very powerful at comprehending
It's very powerful at comprehending and converting audio to text, with no lags. The output quality and the variety of options it provides are also amazing.
I can finally journal every day
Thanks to Letterly, I can finally journal every day. My mind has been so clear from what I’ve been doing each morning with it.
Great app. I've used it many times to transcribe my shorthand notes and then rejig them into format for later use.
