Does this generate a regex from my own examples?

No — true regex synthesis from examples is a much harder problem. This tool offers a curated library of ready-made, correct patterns instead.

Can I tweak a preset pattern?

Yes — pick the closest preset, then edit the pattern text directly to fit your exact needs.

Are these patterns production-ready?

They cover common cases well, but always test against your own real-world data — especially for things like email validation, where edge cases vary widely.
