About this app

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

How it works?
• Record your voice
• Get AI-enhanced excellent text

Letterly is a mobile app that allows you to record your voice, and then – voilà! – you get ready-to-use text. The AI will quickly write the text for you in a way that most likely won't need any editing. Perfect for effortless writing of messages, ai notes, social media posts, and much more. So, don't procrastinate! Just talk, and let the AI do the writing for you!

You can use it for whatever you want:
• Messages
• Emails
• Ideas and thoughts
• Notes or notepad
• Social media posts or blogs
• Task lists and plans
• Articles
• Journaling
• Meetings
• Summaries

It is different from regular note-taking, audio recordings, dictation, transcript, speech-to-text services, live transcribe voice to text, or dictation to text tools.
• NO typing, as we live in the era of artificial intelligence.
• NO spending a lot of time composing text.
• NO replaying audio recordings to decode words (if you only transcribe audio).
• NO losing ideas and their details due to lack of time for writing them down Just SPEAK. AI writing is easier. It's like your personal voice AI writer.

Messages:
Write messages to friends or colleagues without using up your valuable resources. It is really fast and effortless.

Audionotes, speech notes or voice memos:
Quickly voice-capture your notes, especially when your hands are busy. You will get your audionote quickly in a beautiful textual format. Such AI note taker can replace regular tools.

Social media posts:
Create high-quality content by voice and free up time for more important tasks.

Ideas:
Capture your unique ideas. Imagine how many brilliant thoughts you've lost because you didn't have time or energy to write them down! Users with ADHD may find value in this.

Emails:
Compose emails effortlessly, freeing yourself from this extra task that should realistically take 30 seconds. The email AI feature is already quite popular among our users.

Meetings:
Summarize meetings. Record what others say without the need to replay. The text summary will be quickly done. Now you won't miss any details of tasks from your boss or recommendations from your doctor.

Tasks and plans:
You won't forget anything from your to-do list because speaking is 3 times faster than typing.

Writing:
Overcome writer's block with your personal AI writer or AI writing tool. Creative writing or story writing can be made using voice. How much went unwritten because no one listened and helped organize your thoughts? Letterly is that friend who's got your back, your private audiopen!

And this is far from the only use case for Letterly. You can come up with your own use case: replace dictation in your routine, turn it into an AI essay writer - anything you want.

Features:
• Type if you can't speak. You can also summarize or structure text inputs.
• Speak in any language, Letterly supports 50+ languages.
• Share your text easily. Quickly send text via WhatsApp, Telegram, Email, and more.
• Dark and light modes. Choose the interface you prefer.
• Transcribe speech to text if you don't need any rewrites.
• (soon) Personalize your style. The app will paraphrase your speech into formal, casual, academic, etc.
• (soon) Translate your speech. Record in your language, translate to any.

Letterly functions as an interpreter and text summarizer simplifying the way we write. You just record your voice, and like magic, it transforms into ready-to-use text. It's an audio converter or speech AI that makes polished text even with corrected grammar. The AI technology ensures the text is crafted well, eliminating the need for editing.

Convert your audio to text, but not just any text – a well-written one! Be efficient! Be effective!

I used to love this app but lately when I go to record something it tells me that the limit has been reached and/or when it allows me to record, it gives me a recording time of 3 minutes instead of 90 minutes even though I'm a paid subscriber. Sometimes, I have to uninstall the app and reinstall it for it to stop telling me, "Limit reached." It's become a hassle and annoying. Especially since I'm paying monthly for something so inconsistent.

I have been searching for a simple, AI assisted dictation solution for a while. I need to provide quick notes to clients several times a day. Regular voice to text doesn't cut it, and I need the notes to follow simple formatting rules. I tried chatGPT and it struggled with the requests and recently got worse. That pushed me to find a new solution, and I couldn't be happier. The ability to add custom formatting rules is wonderful. I will gladly pay the yearly subscription fee for this app❤️❤️

This app is fantastic. The user interface is extremely intuitive. You simply press a button, speak, and when you're done, it offers numerous options to edit your text in different formats, such as emails, lists, summaries or blog posts (these are paid subscription options). I use it almost daily, and find it particularly useful when I'm walking and need to jot down ideas, write emails, or send notes. There are still some bugs, but the developers are very responsive. Just what I was looking for.
