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.

Best for long brain dumps to extract gold from your mind. it can organize all your chaotic dumped in a well put together list. That's just one of many many uses. I also record meetings with this to extract all the to do items. all the details, all the numbers. I'm no longer missing important things cuz I didn't write it. it's ok there. I love love love this app. I use it often.

This is a very awesome application, and I love the updates that it is getting. The only thing we require next is the security certification. If you get it, we are ensured that the data we are storing and providing to Letterly stays secure and private. Can you please get that certification? Do we have any enterprise versions for this planned?

Thank you for your kind feedback! Please rest assured we take privacy seriously: notes are encrypted in transit and at rest, and we never sell your data or use it for AI training or have the access to it. Security certification is currently too costly for our small bootstrapped team, but we hope to pursue it and enterprise options in the future🤍

this app is truly a game changer especially when im writing emails. All I have to do is just speak to the app and it transcribes all that i said and then im able to choose various rewrites that are so on point. I now never have to type another email. This is truly an amazing app. Bravo to the developers for making such an incredible technology marvel. I truly love it. I must add to my review to say, without a doubt, this is probably the greatest app made and known to humankind. Without a doubt!
