SaaS Library

Browser-based and made for early-stage founders, SaaS Library is a business research tool that collects SaaS product ideas and adds AI tools for writing product descriptions.

Use it when you are still deciding what to build and want to see how other software products are framed before you write any code.

The library covers more than the idea itself.

Entries deal with personas and revenue models, so you can see who a product might serve and how it could earn money.

The AI tools focus on product descriptions, which helps when you need copy for a landing page or a pitch.

Pricing includes a lifetime access option at a discounted price.

That fits you if you expect to return often rather than pay month after month.

The catch is that some features may require unlocking the whole library, so the free view is probably partial.

SaaS Library also looks thin next to established research sources, so use it as a place to find ideas and not as a full market study.
