Frequently asked questions
A few practical answers about access, limits, and how the tools library works.
Do I need an account to use the tools library?
Most standard tools can be used without an account. AI tools require login, and Business / SaaS tools stay open without the browser limit except for Invoice Generator.
Why is Invoice Generator treated differently from the other business tools?
Invoice Generator is the one business tool that still follows the anonymous usage limit. The rest of the Business / SaaS tools remain openly accessible.
How do the AI tools work?
AI tools require login and run with the member's own OpenAI API key. Each AI tool page shows a demo first, then unlocks live use inside the authenticated flow.
Are tool inputs stored on the site?
Most tool workflows are designed for direct browser-side or first-party processing on TechChaps. For AI tools, usage stays behind login because the OpenAI API key flow needs an authenticated path.
