Replix

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

# Chrome Web Store - Publishing Details This document contains the listing description, required justifications, and other details needed when submitting the Replix extension to the Chrome Web Store Developer Dashboard. --- ## 📝 Store Listing Description ### **Short Description (Max 132 characters)** Reply to X posts in one click with GPT-5.6, Grok or DeepSeek. 10 tones, 3 drafts each, written to sound like you. ### **Detailed Description** **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's the hard part. Ten good replies is an hour of your life. Blank box, cold open, and by post six you're writing "Great point!" like everyone else. Replix puts an AI reply assistant directly 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. --- **PICK YOUR MODEL — NOBODY ELSE LETS YOU DO THIS** Every other reply tool locks you to whatever model they wired up. Replix hands you the keys: - **GPT-5.6 Terra** — the balanced default. Fast, sharp, reads nuance well. - **GPT-5.6 Luna** — lighter and quicker, for high-volume days when you're replying to fifty posts. - **GPT-5.6 Sol** — the heavyweight. Reach for it when the thread is technical or the account is big. - **Grok 4.20** — native X energy. Looser, funnier, more willing to be blunt. - **DeepSeek V4** — a genuinely different voice, and remarkably good at dry humor. Switch mid-scroll from the popup. Same tones, same settings — different brain writing them. Models get added as they ship, and you never wait for an extension update: the list refreshes from our servers. --- **10 TONES, NOT 3** Not every post deserves the same energy. Choose from ten distinct voices, each one a separately tuned writing style — not a label on the same generic output: **Neutral** · **Supportive** · **Contradictory** · **Humorous** · **Analytical** · **Casual** · **Professional** · **Controversial** · **Educational** · **Empathetic** Pick one tone and Replix returns **three different takes** to choose from. Or select several tones at once and compare a witty reply against an analytical one, side by side, before you commit. --- **IT DOESN'T SOUND LIKE AI** This is the part most tools get wrong, and the reason people can smell a bot reply instantly. Replix is tuned aggressively against the tells: no "Great point!", no "Absolutely!", no "it's worth noting", no "at the end of the day", no corporate hedging, no hollow agreement, no hashtag spam. It leads with the interesting part instead of building up to it. It varies sentence length the way real writing does. Most importantly, it reacts 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's generic, and generic gets scrolled past. --- **EVERYTHING IS UNDER YOUR CONTROL** - **Reply length** — eight settings, from a 2-word gut punch to 300+ word long-form for X Premium. Concise, short, medium, long, detailed — whatever the moment calls for. - **Emoji level** — none, minimal, standard, or heavy. If you never use emoji, Replix never uses emoji. - **Voice switches** — all-lowercase mode, minimal punctuation, no @mentions, no # symbols, extra line breaks, natural imperfections. Turn your actual habits into settings and every reply inherits them. - **Force a question** — end replies with a genuine question to pull the author into a conversation. Conversations are what the algorithm rewards. - **Language** — automatically mirrors the language of the post, or locks to one you pick. Reply to Spanish posts in Spanish without touching a setting. --- **LIVE WEB CONTEXT** Models are trained on a snapshot of the past. News moves faster than that. Flip on web search and Replix pulls current information before writing, so your reply to a breaking story reflects what's actually happening — not a confident guess from stale training data. Available on paid plans. --- **BUILT FOR SPEED** - **Keyboard-first** — Ctrl/Cmd+Shift+L generates a reply. Ctrl/Cmd+Shift+E jumps between posts. Work the timeline without ever reaching for the mouse. - **Native rendering** — Shadow DOM isolation means Replix looks and behaves like part of X itself. No broken layouts, no style bleed, no flicker. - **Actually fast** — replies land in roughly 1–2 seconds. Fast enough that you stay in the scroll instead of waiting on a spinner. - **Usage at a glance** — the popup shows exactly how many replies you've generated and posted today. --- **PRIVATE AND SECURE BY DESIGN** - Sign in with **Google OAuth 2.0**, or with **email and password** — passwords are hashed with bcrypt and never stored in plain text. - AI provider keys live on **our servers**, never in your browser, never in the extension bundle. - Replix runs on **x.com and twitter.com only**. It cannot see any other site you visit. - We don't sell your data, and we don't train on your replies. --- **HOW IT WORKS** 1. **Install** — add Replix to Chrome and pin it to your toolbar 2. **Sign in** — Google or email, about ten seconds 3. **Set your voice once** — model, tone, length, emoji level 4. **Browse X normally** — timeline, profiles, search, anywhere 5. **Click a Replix button** under any post 6. **Pick a draft**, tweak it if you want, hit send Total time from install to first reply: under a minute. --- **WHO IT'S FOR** - **Content creators** — grow by consistently showing up under bigger accounts in your niche, instead of shouting into your own timeline - **Founders & indie hackers** — build in public and actually talk to potential users, at a volume you can sustain - **Marketers & agencies** — keep several accounts genuinely active without burning a full day on it - **Job seekers & professionals** — become a familiar name in your industry's conversations - **Everyone else** — land the joke in a viral thread while it's still climbing --- **COMMON QUESTIONS** **Will people know it's AI?** Not if you pick well. Replix drafts read like a sharp person typed them fast — and you're free to edit before sending. It's a first draft, not an autopilot. **Does it post automatically?** Never. Replix drops the draft into X's reply box. Nothing sends without you clicking send. **Do I need my own API key?** No. Every model is included — nothing to configure, no separate billing. **Does it work on the X mobile app?** It's a Chrome extension, so it works in Chrome on desktop, including x.com in a mobile browser that supports extensions. **Can I change my mind about the model?** Anytime, from the popup. Your tone and length settings carry over. --- **START FREE — 2 AI REPLIES PER DAY, NO CARD REQUIRED** Upgrade when you want volume, web search, and long-form. Cancel whenever — your plan stays active through the period you've paid for. The accounts growing on X right now aren't posting more. They're replying better. **replix.aigentlabs.org** --- ## 🎯 Single Purpose Chrome policy requires every extension to have one narrow, easily understandable, and clearly defined purpose. > **The single purpose of the Replix Chrome Extension is to provide an AI-powered writing assistant that injects directly into the X (formerly Twitter) platform interface, allowing users to generate and draft context-aware replies to posts with a single click.** --- ## 🔒 Permissions Justification You must justify why the extension requests each permission in the `manifest.json`. ### 1. `activeTab` > **The `activeTab` permission is strictly necessary because the Replix extension needs to read the text of the current post the user is actively viewing on X/Twitter. This text provides the context our AI model needs to generate a relevant reply. Additionally, it allows us to inject our UI reply buttons directly into the DOM of the active tab only when the user is navigating on our supported domains (twitter.com, x.com).** ### 2. `storage` > **The `storage` permission allows us to locally save user preferences (such as preferred language or default response tones) and securely store authentication tokens for interacting with our Replix server. This ensures the user doesn't have to log in every time they open their browser or navigate to X/Twitter.** ### 3. `scripting` > **The `scripting` permission is necessary because the Replix extension must inject specific content scripts (JavaScript code) into the DOM of the supported web pages (twitter.com, x.com). These scripts are essential for reading tweets, injecting the AI reply buttons directly beneath original posts, and inserting the AI-generated text back into the tweet composition box.** ### 4. `tabs` > **The `tabs` permission is required to detect when the user is actively navigating on specific domains like twitter.com or x.com. It allows the extension to know exactly when to activate and properly load our content scripts only on those relevant tabs, ensuring it works correctly without interfering with the user's browsing experience on unrelated websites.** ### 5. `identity` > **The `identity` permission is used exclusively to handle secure user authentication via Google OAuth 2.0. It allows users to log into their Replix account quickly and safely, without needing to create and store new passwords within the extension.** --- ## 🌐 Host Permissions You must justify why the extension needs access to the specific domains listed in the manifest (`twitter.com`, `x.com`, `replix.aigentlabs.org`, etc.). > **Host permissions for `twitter.com` and `x.com` are required for the extension to integrate, read posts, and function correctly within the interface of these specific social platforms. The permission for `replix.aigentlabs.org` is essential to allow secure communication between the Chrome extension and our private backend servers, which is necessary to process AI generation requests, fetch user preferences, and handle API authentication.**
