Never stare at a blank reply again. Echo is your personal AI writing assistant for everyday messaging. Whether you need to reply to a tricky message or fix something you already wrote, Echo handles it in seconds โ in your voice, not generic AI text. REPLY FOR ME Paste any message you received and Echo instantly generates 3 ready-to-send replies. Each one uses a different tone โ Casual, Professional, Empathetic, Witty, Firm, and more โ matched to the context of the message. A work email gets polished professional options. A friend's text gets warm and natural ones. You pick the one that sounds right and send. REWRITE Type or paste something you already wrote and Echo cleans it up โ fixing grammar, improving flow, and sharpening the wording. Choose your correction style: keep your Original voice, make it Cleaner, more Professional, Friendlier, Shorter, or Grammar only. See a plain-English summary of exactly what changed, then copy and send. COMPOSE BY VOICE Not sure what to say? Just record yourself describing what you want to send. Echo extracts your intent, and writes the message for you โ no typing required. LEARNS YOUR VOICE Echo studies how you actually write and builds a personal style profile. The more you use it, the more the "Sounds Like You" reply sounds like it came from you โ not from an AI. Your vocabulary, your sentence length, your humor, your punctuation habits. All of it. WORKS FOR EVERYTHING โ Text messages and iMessage โ WhatsApp and Telegram โ Emails and Gmail โ LinkedIn and professional DMs โ Instagram, Twitter, and social replies โ Any app where you type Echo requires a subscription to use. Start with a 3-day free trial โ no charge until your trial ends. $4.99/month or $29.99/year. Cancel anytime. Echo does not read your messages, connect to your accounts, or store your conversations. Everything is paste-based and private. Privacy Policy: https://www.dotcomtechlabs.com/echo/privacy-policy Terms Of Use: https://www.dotcomtechlabs.com/echo/terms-of-service

Verdict
The clearest difference is in-app purchases: ReplyLens at none against Echo's 2. Echo's advantage is iOS requirement (15.1 vs 17.0). On price, ads and device support there is nothing between them.
