Replix by AigentLabs

The fastest way to reply to tweets using AI and the easiest way to boost your tweet impressions.

REPLY LIKE THE SMARTEST PERSON IN THE THREAD — IN ONE CLICK Everyone tells you to post more. The accounts actually growing are the ones replying: showing up under bigger posts, day after day, with something worth reading. That is the hard part. Ten good replies is an hour of your life, and by post six you are writing "Great point!" like everyone else. Replix puts an AI reply assistant inside your timeline. Click once under any post, get three drafts written in your voice, pick one, send. No new tabs, no copy-paste, no staring at an empty box. CHOOSE YOUR MODEL Most reply tools lock you to a single model. Replix offers fourteen, from the quickest small ones to the sharper general-purpose ones, and you can switch between them from the popup. Same tones, same settings — a different voice writing them. The list is served by our servers, so a new model appears without waiting for an extension update. TEN TONES Neutral, Supportive, Contradictory, Humorous, Analytical, Casual, Professional, Controversial, Educational, and Empathetic. Each is a separately tuned writing style. Pick one tone to get three different takes, or select several tones and compare them side by side. IT DOESN'T SOUND LIKE AI Replix is tuned against the usual tells: no "Great point!", no "Absolutely!", no corporate hedging, no hashtag spam. It leads with the interesting part instead of building up to it, and it varies sentence length the way real writing does. Most importantly, it responds to what the post actually says, not to the topic in general. If a reply would work equally well under a different post about the same subject, it is generic — and generic gets scrolled past. SETTINGS YOU CONTROL Reply length — eight options, from a two-word response to 300+ words for X Premium Emoji level — none, minimal, standard, or heavy Voice options — all-lowercase, minimal punctuation, no @mentions, no hashtags, extra line breaks, natural imperfections Force a question — end replies with a genuine question to start a conversation Language — mirrors the post's language automatically, or locks to one you choose LIVE WEB SEARCH Turn on web search and Replix pulls current information before writing, so replies to breaking news reflect what is actually happening. Available on paid plans. BUILT FOR SPEED Keyboard shortcuts — Ctrl/Cmd+Shift+L to generate, Ctrl/Cmd+Shift+E to move between posts Shadow DOM isolation — Replix renders natively inside X without breaking layouts Replies typically arrive in 1–2 seconds The popup shows how many replies you have generated and posted today PRIVACY AND SECURITY Sign in with Google OAuth 2.0, or with email and password (passwords hashed with bcrypt) AI provider keys stay on our servers, never in your browser and never in the extension bundle Replix runs on x.com and twitter.com only, and cannot see any other site you visit WRITTEN WITH CARE Replix writes under explicit rules: a claim is reported as the claim of the person who made it, nothing is asserted about a private individual, and missing evidence is asked for rather than implied. Dissent, sarcasm and hard criticism are all allowed — the rules aim the edge at the argument, not at a private fact about the person. You always read the draft before it goes anywhere. HOW IT WORKS 1. Install Replix and pin it to your toolbar 2. Sign in with Google or email 3. Set your model, tone, length and emoji level 4. Browse X as usual 5. Click a Replix button under any post 6. Pick a draft, edit if you want, and send WHO IT'S FOR Replix is for anyone who replies on X and would rather send a reply worth reading than a quick one. If you have ever closed the tab instead of writing the reply you had in your head, this is built for that moment. COMMON QUESTIONS Will people know it's AI? Replix produces a first draft, not an autopilot. You can edit anything before sending. Does it post automatically? No. Replix places the draft in X's reply box. Nothing sends until you click send. Do I need my own API key? No. All models are included. Does it work on the X mobile app? It is a Chrome extension, so it works in Chrome on desktop and in mobile browsers that support extensions. Can I change models later? Anytime, from the popup. PRICING Start free with 6 replies a day, no card required. Plans start at €3.99 a month for higher volume, web search and long-form replies.
