Frequently asked questions

How does the effort estimation work?

IssueSizer analyzes your repository history, code complexity, and issue descriptions using AI to predict effort in story points or hours based on patterns from your past work.

Does it work with private repositories?

Yes. We connect via GitHub OAuth with the minimum required scopes. Your code is never stored — only metadata and aggregated statistics are used for analysis.

Can it automatically estimate new issues?

Absolutely. Set up our GitHub webhook once and every new issue gets an estimate posted as a comment within seconds, keeping your backlog groomed automatically.
