Sharing a solution

Sometimes you want to send a finished solution to a friend, a teacher, or a study group. Share links make this one click.

Create a share link

Open any solution and click Share in the top right. We generate a short URL that looks like ostrol.com/share/abc123. Anyone with the link can view a read-only copy of:

• The original problem
• Every step in the solution
• The verification badge

What we don't include in a share link: your email, your name, the rest of your solve history, or any account information. The recipient sees a clean page with just the math.

Who can view a share

Share links are public-but-unlisted. There is no password and no sign-in wall — anyone with the URL can open it, but the URL is long enough that it can't be guessed.

If you need something stricter (auth-gated sharing, expiry dates, view counters), those features are part of the Pro plan — see Plans and pricing.

Revoke a link

Decided you don't want a solution out there any more? Open the solution and click Share → Revoke link. The URL stops working immediately for everyone, including people who already opened it but didn't reload.

You can also see and revoke every active link in Settings → Shared links.

Editing after sharing

If you edit the original solution after sharing, the share link updates automatically — your friend gets the corrected version when they reload. There's no need to revoke and re-create.

Sharing into Google Classroom or Microsoft Teams

Paste the share URL directly into an assignment, a comment, or a chat message. Most platforms render a preview card with the problem, so students see what they're clicking before they tap.

For exports that don't require an internet connection — PDF, PNG, LaTeX — see Exporting to PDF.
