You're losing relationships on X every week.
You just don't see it.
Relationships you were building. Gone.
tendX tracks every like, reply, and DM you send. One click to keep someone on your radar. You always know who you talked to, and when.
X doesn't track your relationships. Neither do you.
You like their posts. Reply to their threads. DM back and forth. You’re starting to recognize each other.
7:48 PM
You get busy. Miss a few days. Then a few more.
7:49 PM
X stops showing you their posts. You don’t notice.
8:07 PM
Weeks pass. They’ve disappeared from your feed.
8:08 PM
A future cofounder. A friend. You’ll never know what that relationship could have become 😨

How it works
See who you're
engaging with
Spot someone worth connecting with?
Open the tendX side panel and click "Add to CRM." They're on your tracked list. No spreadsheets, no switching apps.
Use X the way you already do
With automatic tracking on, tendX logs your interactions as they happen. Prefer more control? Switch to manual anytime.
See who you've gone quiet with
Your dashboard tracks every interaction with the people you follow. When someone goes quiet, you'll know. Before the silence becomes permanent.
Install once. See everything.
We can't see your data. We built it that way.
Everything tendX records stays in your browser. If you want it in a spreadsheet, it syncs to a Google Sheet you own.
Stored on your device
Your engagement history lives in your browser's local storage. No servers, no cloud.
No access to your X account
tendX never logs in and never requests API access. It watches what you do in your own browser.
We don't see who you track
tendX has no analytics on your activity. We don't know who's in your network or how you engage with them.
Export anytime
Sync to a Google Sheet you own. It's yours to keep.

Tracking runs in the background
