Sequel AI

AI post composer for X and LinkedIn, plus post stats on X: views per hour, engagement rate and time left in the feed window.

Prospel is the AI ghostwriter for X and LinkedIn that sounds like you. This extension brings it into the page, so you can draft posts, suggest replies and see post stats without leaving X or LinkedIn. You need a Prospel account (prospel.app). Sign in once on prospel.app and the extension picks up your session automatically. WHAT IT DOES ✍️ Draft a post where you write it Click "Write with Prospel" next to the X composer or on LinkedIn's "Start a post" box, or open the Prospel sidebar from the button in the corner. Describe your topic, choose a single post, a thread or several options, pick short, medium or long, and Prospel drafts it in your voice. Then insert it straight into the composer, add it to your Prospel queue, or copy it. 💬 Suggest a reply in your voice Open a reply on X or a comment on LinkedIn and click "Suggest Reply". Pick a tone (Agree & Contribute, Build On It, Contrarian or Hot Take) and Prospel drafts a reply that reads the post and the thread above it. Edit it, insert it, or bin it. 🔁 Remix any post into your own words Every post gets a "Remix" button. Prospel takes the idea and rewrites it in your voice, without quoting or tagging the original author. Add a note to steer it if you like. Post stats X doesn't show you A small line under each post on X shows: - views per hour since it was posted - engagement rate: replies, reposts, likes and bookmarks divided by views - a "reply-heavy" flag when the conversation is doing the work - hours left in the 48-hour window that X's open-sourced ranking code keeps posts in Everything is read from the page you're already looking at. No extra API calls, and nothing is sent anywhere. Turn it off with one toggle in the popup. Your drafts, wherever you are The Drafts tab shows the posts waiting in your Prospel account for that platform. Insert one into the composer or add it to your queue in a click. Profile insights on X On an X profile, the Insights tab shows follower count, average likes per post, an engagement rate X doesn't display, posting frequency and the best recent post. Add the account to your Target Voices in Prospel from there. A quick look at your day The popup shows how many posts went out today and this week, your posting streak, and links to your dashboard. FITS IN, STAYS OUT OF THE WAY - The sidebar follows X and LinkedIn's own light or dark theme. - Nothing is posted for you. Drafts only go into the composer or your queue when you click. - Your voice comes from your Prospel Persona: your best posts, your style guide for each platform, and your own true stories. Prospel is built not to invent anecdotes, numbers or experiences. ABOUT PROSPEL Prospel learns how you write, drafts posts from things that really happened, and publishes them on a schedule you approve. It's built for founders, creators and coaches on X and LinkedIn. Every plan starts with a 5-day trial.
