They just overthink it, rewrite it five times, or never hit post. SignalX fixes that. It sits directly inside X and helps you: * turn raw thoughts into sharp replies * respond faster without sounding robotic * focus only on high-signal tweets worth engaging with * highlight tweets related to your niche No rate limits. No switching tabs. ⚡ CORE REPLY MODES ━━━━━━━━━━━━━━━━━━━━━━━━ ① AI Chat Mode (natural & iterative) Chat with SignalX directly on any tweet. * understands the tweet + context * refine your reply in natural language * remembers previous messages in the same conversation * adjust tone, length, or angle until it feels right This feels like thinking out loud, not prompting an AI. ② Intent-Based Replies (one-click speed) Generate replies based on intent. * choose from common intents (agree, challenge, add value, question, funny, etc.) * or write your own custom intent * generate multiple reply options at once * edit and post any reply in one click Perfect when you want speed without sacrificing quality. ③ Rephrase Your Thought (human polish) Already know what you want to say? * paste your raw thought (any language) * SignalX rewrites it into multiple clean English replies * keeps your meaning, removes awkward phrasing You stay in control. AI just sharpens it. 🧠 PRODUCTIVITY & SIGNAL ━━━━━━━━━━━━━━━━━━━━━━━━ SignalX is not just about replies. ✓ High-signal feed ranking – surfaces tweets actually worth engaging with ✓ Niche Highlighter - Visually surfaces tweets containing the topics you care about ✓ Noise & ad hiding – less distraction, more focus ✓ Multiple replies at once – reply to many tweets in parallel ✓ Simple UI – no learning curve, no clutter ✓ Usage analytics – understand what works for you Everything is designed to save time, not add features for the sake of it. ♾️ UNLIMITED & FAST ━━━━━━━━━━━━━━━━━━━━━━━━ * no rate limits * reply as much as you want * works directly on x.com * one-click insert + post Because SignalX does not use the official X API, you’re not artificially limited. 🔒 PRIVACY FIRST ━━━━━━━━━━━━━━━━━━━━━━━━ SignalX is built with privacy as a default, not a checkbox. * we never post without your action * we never sell or share your data You own your data. Always. 💸 PRICING (HONESTLY) ━━━━━━━━━━━━━━━━━━━━━━━━ SignalX is intentionally affordable. You pay for value, not inflated SaaS margins. BTW, Free Trial is also available.
