Reply Lab is the AI keyboard that generates replies inside any app you type in - iMessage, WhatsApp, Instagram, Snapchat, Tinder, Slack, and more. No app-switching. No copy-paste. No screenshotting conversations to upload somewhere else.
Unlike standalone AI apps, Reply Lab works as a keyboard - so it functions inside apps like Snapchat where you can't copy-paste at all.
How It Works
Add Reply Lab as a keyboard, switch to it with the globe icon, and generate AI replies right where you're typing. Everything happens inside the keyboard - even screenshot analysis runs in-place without leaving the conversation.
Key Features
Works Everywhere - One keyboard for every messaging app. Dating, work, friends, family - even apps where copy-paste doesn't work.
15+ Reply Tones - Professional, Flirty, Funny, Savage, Gen Z, Sarcastic, and more. Match the vibe of any conversation.
In-Keyboard Screenshot Analysis - Paste a screenshot of a conversation and get context-aware reply suggestions directly from the keyboard.
Custom AI Modes - Write your own system prompts 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.
