OneShot – Create annotated demo HTML files from screenshots with a one-time payment

Summary: OneShot is a pay-once tool for indie hackers to create demos by uploading screenshots, adding annotations, and exporting HTML files. It offers core demo creation features without subscription fees, targeting occasional users who need 2-3 demos per year.

What it does

Users upload screenshots, add annotations such as arrows, text, and hotspots, then export the result as an HTML file they can own and use indefinitely.

Who it's for

Indie hackers and founders who need occasional demos for Product Hunt launches, landing pages, or pitch decks without ongoing subscription costs.

Why it matters

It eliminates recurring fees for infrequent demo creation by providing a one-time $20 purchase with lifetime ownership of exported demos.
