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.

x.com/chat

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.

Install once. See everything.

No servers. No cloud. Just your browser.

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.

Features

Everything you need.

tendX does the tracking. You do the relationship.

Add anyone in seconds

See someone worth knowing? Open the side panel, hit one button, done.

Tracking runs in the background

Nothing slips through. tendX catches your activity while you browse. No extra steps. Prefer to be selective? Switch to manual and track only the interactions you choose.
