Open dashboard
Sign out
Try it — click "Send this page to Preplani"
You save a tutorial, bookmark a long-read, add a talk to Watch Later — and never see them again.
The extension captures learning at the moment you find it, files it under a goal, and turns it into steps you'll actually complete.
How it works
From open tab to study plan in three steps
No copy-pasting links. No switching apps.
-
STEP 01
Install & connect
Add Preplani to Chrome and sign in once. The popup confirms you're connected.
-
STEP 02
Choose a goal
Pick a default goal — or name a new one right inside the extension.
-
STEP 03
Send the page
Hit "Send this page" from the toolbar, or use the launcher floating on the page.
On-page launcher
Send it without leaving the page
A small Preplani launcher sits in the corner of every YouTube video and article. Click it, confirm where it belongs, done — your reading or viewing never gets interrupted.
- Works on YouTube videos and web articles
- Choose or create a goal in the same dialog
