About this app

This app saves your time and energy by converting your speech into clear, structured, well-written text. And it's not only voice transcription.

How it works:
* Record your voice
* Get AI-enhanced, ready-to-use text

Letterly is a mobile app that lets you record your voice and quickly turn it into polished text. The AI helps rewrite your speech in a clear, useful format that usually needs little or no editing. It is perfect for effortless writing of messages, notes, social media posts, emails, ideas, plans, and much more. Just talk, and let AI help with the writing.

Android AccessibilityService API disclosure

Letterly Dictation is an optional voice-based input feature that can help users who have difficulty typing on a mobile keyboard, including users with motor impairments or hand-mobility limitations, dictate text directly into other apps such as messages, emails, notes, and documents.

To do this, Letterly uses Android AccessibilityService API to find the text field you are typing in and place your dictated text there.

When you dictate, your audio recording is sent to Letterly servers and transcription/AI service providers to turn your speech into text and create the final result.

Letterly does not use Android AccessibilityService API to read passwords, payment fields, or banking fields, record calls, change your device settings, bypass Android privacy controls, or control your device without your action.

You can turn this feature off anytime in Android Accessibility settings.

You can use Letterly for:
* Messages
* Emails
* Ideas and thoughts
* Notes
* Social media posts and blogs
* Task lists and plans
* Articles
* Journaling
* Meeting notes
* Summaries

Letterly is different from regular note-taking, audio recording, dictation, speech-to-text, live transcription, and voice-to-text tools.

* No typing when speaking is faster.
* No spending extra time composing text from scratch.
* No replaying audio recordings just to understand what was said.
* No losing ideas because you did not have time to write them down.

its so frustrating to use this app to send whatsapp messages! I bought subscription to send whatsapp messages while driving but its impossible. I see the icon but nothing happens on pressing it. after multiple tries, it works in a while. its much easier to type it yourself. the developers have to understand if such an app is not user friendly, its a waste of time.

Sorry about this, and thanks for your review — it helped us find the issue. A small finger movement was sometimes treated as a swipe, so the button didn’t respond. We’ve fixed it and released an update. Please try it and let us know if it works better now.

I've used this a few times to capture notes. It corrects language and slips with clean emails, notes and posts. I must have reached the lifetime threshold payment. my app says nothing about forthcoming renewals. i hope that is the case.

This is a pretty sweet app. Its incredible how accurately it captures/predicts even the blurry phrases. I would like to point out two bugs in the app which Samsung/Google users would primarily face. When you turn ON the diction bubble, it will act as touch/tap blocker while using other apps that have a sensitive popups. Snoozing the diction bubble would not help. I hope this bug is fixed soon. Maybe auto hiding on configured apps from UI would help.
