Doesnt appear to work with Xiaomi
The letterly bubble rarely appears even though it has granted all the access it needs. I have used whispr flow before and love it. I thought this looked promising. Support has been non responsive.
EDIT The correct settings is to turn the letterly shortcut on as well. then the shortcut can enable the letterly bubble . This means that the bubble does not appear immediately and automatically when you activate the text box, so its a two step process (not like in whispr flow)

If it comes back on App Sumo just get it
I managed to set up a webhook so whatever I want to save in my drive is done at the touch of a button.
I used Albato to configure it ( thanks app sumo for albato) .
I have it on my laptop and mobile phone and find it similar to Otto.ai.
when i, writing my next book i will be using this heavily .. Definitely 5 tacos . I hope they stick around for a long time and add more features

Lifetime deal broken on mobile and desktop — no support reply since January
I bought the lifetime deal through AppSumo. The web interface still correctly shows my lifetime membership — but no other platform does.
In the mobile app I'm prominently prompted to buy a Pro membership, and the Pro features are no longer available to me there. When I try to sign in to the desktop app, I get the message "All slots are in use — 2 of 2 slots occupied", even though I have exactly one mobile app installed. In practice, the deal has been reduced to a single platform.
I reported this three times by email to the "support email" (Appsumo blocked my review for writing the public facing support Email Address of Letterly) on January 7, February 4, and March 17. I have received no reply to any of them — not even an automated acknowledgement or a holding message.
I like the idea behind the product, but a lifetime deal whose licensing doesn't work, combined with a support address that has been silent for months, isn't usable for me. I'll happily update this review once someone gets in touch and the slot/licensing issue is resolved.

Sep 9, 2026Dear Simon,
We're really sorry this happened 🙏
We can see that we did reply to you, but for some reason our messages didn't get through. We've just sent you all the information again by email — please let us know if you see it this time.
Your license is fixed. Please have a look: an "Upgrade to Pro" button should appear on your phone — tap it and your lifetime license comes back.

Good but British English not a supported language.
Letterly integrates smoothly with popular apps and handles multiple speakers well when transcribing conversations. The PC web version, letting me upload audio files directly, is a real bonus. My gripe is that transcriptions default to American English, so British spellings need correcting afterwards. Selecting British English from the Format and Tone prompts doesn't work within phone apps, so it's not a genuine fix. Still a solid tool overall, four stars.

Sep 3, 2026Thank you so much for your feedback! We’ve heard this from quite a few British users too!
The model tends to default to American English, and making British English work consistently is a bit more complex than it may seem — but it’s definitely on our radar and we’re working on it! :)
Thanks again for your support! 💛
