About this app

Subtext is your writing and communication assistant for everyday messages, replies, and difficult conversations.

Write from scratch, paste a draft, or share a screenshot of a conversation. Subtext helps you see how your message may come across, improve your wording, and draft replies that feel clear, thoughtful, and natural.

Use it for texts, emails, dating conversations, work replies, group chats, follow-ups, check-ins, and those moments when you know what you want to say but not exactly how to say it.


WHO IT'S FOR

- People who rewrite the same message five times before sending
- Overthinkers, over-editors, and anyone wondering "does this sound okay?"
- People navigating sensitive conversations, follow-ups, boundaries, or unexpected replies
- Anyone who wants their writing to better match their intention


WHAT SUBTEXT DOES

- Message Analyzer: Review tone, clarity, and how your message may come across. Spot wording that could feel unclear, too harsh, too passive, or easy to misread.
- Writing Coach and Proofreader: Understand why certain phrases need work and how to improve them. Fix grammar, spelling, and sentence structure automatically.
- Smart Reply and Response Generator: Generate or improve replies based on conversation context. Paste a screenshot or type the conversation, and get response options that fit.
- Tone Tuner: Make your message warmer, clearer, shorter, softer, firmer, or more professional.
- Rewriter and Rephraser: Turn rough drafts, scattered notes, and half-finished thoughts into polished messages.
- Context Summary: Paste a full conversation and get a breakdown of the key points, possible tone and intent, and reply options.

Subtext uses AI to analyze tone, suggest improvements, and help you communicate with more confidence, one message at a time.

Ratings and reviews

"I consent to sharing my input texts and screenshots with our Al provider Anthropic and voice records with Deepgram for smart insights, edits and response generation." Not only is it not private, it's also not even a free app. Very misleading. You can't do anything without being forced to subscribe.

I'm writing this before seeing the sticker price which will def effect stars, review. Stay tuned. FREE version, so far? Amazing!! I have ChatGPT pro, and this is wholly different, which is the best test. It edits, sums my ADHD, long-winded texts while retaining the substance with little direction. How, is a mystery to me. Saves me hours! I've not had pesky popups, timed ads, or faux "updates" that mimic the app. Fast, clean, near perfect!

the concept is really awesome! but you can't even get through the first prompt of asking it to analyze messages and give you a clean fixed message to send without it telling you that it's locked behind a paywall. there should definitely be more options on the free tier especially since it's literally $6 a week or $50 a year! that's ridiculous.
