X Post Radar scores each post on your X timeline from 0 to 100 for how likely your reply is to be seen, highlights the ones worth your time, and can hide likely AI-written noise. Reply where it counts and grow your presence on X. The scoring runs in your browser, so your timeline stays on your device.
The waitlist button opens your email app with a ready-to-send message.
Every post on your timeline asks for your attention, and more of the feed is noise, including replies that read as AI-written. X Post Radar marks the posts worth reading and replying to, and can hide likely AI posts, so your time goes to people and conversations that matter to you.
A reply on the right post is read by that post's audience, not only by your followers. The radar points you to fresh, fast-moving posts in your niche, where a thoughtful reply has the best chance of being seen and of making people curious about your profile.
Your timeline shows every post the same way. It does not tell you which ones are still gathering readers and which conversations have already moved on, so you pick by feel.
You spend ten minutes on a careful reply to a post from this morning. By then the conversation is over.
You reply to a large account, but the thread already holds hundreds of replies. Yours lands near the bottom.
A fresh post in your niche is picking up likes fast, and you scroll past it because nothing marks it.
Each reply takes the same effort whether a handful of people see it or thousands. Picking the wrong posts adds up.
X Post Radar reads the posts visible on x.com, scores each one and marks it high, medium or low priority right in your timeline. You decide where to reply; the extension never posts for you.
Reach velocity, the author's audience, how fresh the post is and whether it invites discussion all feed the score, so a fast-moving post from the right account gets the higher score.
Add niche keywords and posts that match none of them are capped at low priority. Mute keywords keep posts you never want ranked off the radar.
Change signal weights and thresholds from the popup. The radar also learns locally from which badged posts you engage with.
Turn on the AI-likelihood check to see how likely each post is AI-generated, and why, and optionally hide posts above a threshold you choose. It runs in your browser with no key.
Bring your own TypeSafe API key to show an AI-based score next to the local one. Off by default.
No X API, no account with us, no tracking.Scoring and settings stay in chrome.storage.local on your device.
Add your niche keywords and mute keywords in the extension popup.
Open x.com and scroll as usual. Each visible post gets a 0–100 badge: high, medium or low.
Reply to the high-priority posts yourself, in your own words.
The score answers one question: how likely is it that your reply to this post is widely seen? Relevance gates, reach scores.
A post with almost no engagement cannot reach High. A reply thread already crowded for the post's reach is pushed down, because a reply landing 800th will not be read.
The score is a decision aid, not a guarantee of reach or engagement.
| Feature | When | What is sent, and where |
|---|---|---|
| Local scoring | Always on | Nothing. |
| TypeSafe score | Off by default. You turn it on and add your own key. | The text of highlighted posts, their public like, retweet and reply counts and age, and your niche keywords, to api.typesafe.ai. |
| AI-likelihood check | Off by default. | Nothing on its own. With the TypeSafe score also on: the text of every visible post, to api.typesafe.ai with your key. |
| Pro license check | Only after you press Upgrade to Pro or Restore purchase. | A random install identifier, to extensionpay.com. No timeline content. |
| Pro product promotion | Only when you press Scan, Find leads or Write draft. | Your product's page text, collected post text or one post, to api.typesafe.ai and your own LLM provider, with your own keys. |
| Key test | Only when you press Test in Settings. | One short fixed test message, to that key's own service. |
Scoring is identical on Free and Pro. TypeSafe uses your own TypeSafe API key on every plan.
