Problem Ledger – Validate startup ideas with evidence, not assumptions

Summary: Problem Ledger is a browser extension that helps validate startup ideas by capturing real user complaints and pain points from online sources. It uses AI to detect patterns and builds evidence that a problem is worth solving before investing in product development.

What it does

It captures user feedback and problem evidence while browsing, including Reddit threads and blog posts, using AI pattern detection and a passive Watch Mode. It is available as a Chrome extension, with Firefox and Edge versions coming soon.

Who it's for

Solo founders and startup teams seeking systematic validation of problems with proof of user willingness to pay before building solutions.

Why it matters

It addresses the gap between identifying a problem and confirming that users will pay to solve it, reducing wasted time and resources on unprofitable products.
