Meet our most overlooked free tool: the Tweet Source Link Extractor

We have a tool that's been live for months, runs in three different surfaces, costs us nothing to operate, and could be useful to anyone who's ever wanted to share someone else's tweet. Almost nobody knows it exists. That's on us.

This post is the introduction we never wrote.

What it does, in 30 seconds

The Tweet Source Link Extractor takes any X / Twitter post URL and pulls out that post's own t.co link — the short URL X uses internally for every tweet. Drop that t.co link into a new tweet, and X expands it into a full embedded card of the original. Add your caption, hit Post: you've shared the tweet, your followers see it big and clean, and the original creator gets the views and click-throughs.

It's the cleanest single-tweet way to repost someone else's content with credit baked in. Better than a screenshot (which strips attribution entirely). Better than a quote-tweet (which buries the original in a tiny preview). Just: a normal tweet that links to the original, the way X was designed to work.

How it's free

Every step happens in your browser or against X's own public syndication endpoint. We don't pay for an X API tier, we don't run a paid scraper, we don't bill against anyone's quota. The Chrome extension does it locally. The web tool fetches the public syndication metadata and returns the embedded t.co. The bookmarklet calls the same endpoint from your phone. No costs, no rate limits, no signup.

Three ways to use it

We built this thing three times because the right entry point depends on where you are when you see the tweet.

From the Chrome extension — the XposterAI extension drops a small Repost with source button next to every tweet's action row. One click → compose window opens with the source link prefilled. This is the version we use ourselves.

From the web — paste any tweet URL into /tools/tweet-source-link-extractor, click the button, land on the X compose window with the source link ready. No login. Bookmark the page for one-click access.

From your phone — save a tiny one-line JavaScript bookmark in desktop Chrome, let Chrome Sync push it to your phone, and tap it on any tweet page in mobile Chrome. The compose window opens with the source link prefilled. Looks fussy written out; about four taps in practice.

The full how-to walkthrough lives here with screenshots for each method.

Why we made it

XposterAI is a Chrome extension for generating AI replies on X. That's the paid product. But the underlying problem — making it easier to engage on X without being a jerk — runs deeper than replies. One of the most common forms of accidental jerkiness on X is repost-without-credit: someone tweets something good, someone else screenshots it or copy-pastes the text, and the original creator gets nothing.

We can't fix the screenshot habit on our own. But we can make giving credit so frictionless that there's no reason not to. That's what this tool is. It's free, and it's going to stay free, because the underlying problem isn't a feature we should monetize — it's a workflow that should just exist.
