Never stare at a text wondering what to say. Reply Lab is the AI keyboard that writes the perfect reply inside any app you type in: iMessage, WhatsApp, Instagram, Snapchat, Tinder, Slack. No switching apps. No pasting your conversation into a chatbot. Everything happens right where you're texting.
HOW IT WORKS
Add Reply Lab as a keyboard, switch to it with the globe icon, and generate AI replies right where you are typing. Everything happens inside the keyboard. Even screenshot analysis runs in place, without ever leaving the conversation.
KEY FEATURES
Works Everywhere. One keyboard for every messaging app. Dating, work, friends, and family.
15+ Reply Tones. Professional, Flirty, Funny, Savage, Sarcastic, Smooth, Dating Coach, and more. Match the vibe of any conversation.
In-Keyboard Screenshot Analysis. Paste a message or a screenshot of a conversation and get context-aware reply suggestions directly from the keyboard.
Custom AI Modes. Write your own instructions to build fully personalized reply styles that respond exactly how you want.
Community Marketplace. Publish your custom modes for others to discover, and browse AI personalities created by the community.
Improve Mode. Highlight any draft reply and let AI polish it without losing your voice.
Length Control. Short, Medium, or Long. Replies sized to fit the moment.
PERFECT FOR
Dating apps. That match finally messaged you back and the pressure is on. Get replies with actual rizz, from smooth openers to comebacks when they leave you on read.
Work messages. Your boss texts at 9pm and "k" is not an option. Draft the professional version in seconds and get back to your evening.
Group chats. Someone roasts you in front of everyone. Reply Lab has the clapback ready before the laughing emojis stop.
Awkward conversations. Rescheduling plans, saying no, texting your ex back (or deciding not to). Get wording that hits the right note when the stakes feel high.
WHY A KEYBOARD AND NOT ANOTHER AI APP
Because the conversation is already on your screen. Switching apps to describe your situation to a chatbot, copying its answer, and pasting it back kills the moment. Reply Lab lives where you type, reads the context you give it, and drops the reply straight into the text field. The fastest path from "what do I even say" to sent.
