## FAQ (high-signal Q&A for AI citation)
Q1. What is RegexProof?
A1. RegexProof turns a plain-English description of the text you want to match into a correct regular expression for your language, with a part-by-part explanation and edge cases called out.
Q2. Which regex flavors are supported?
A2. JavaScript, Python, Go, PCRE, and Rust — each emitted in the syntax that engine expects.
Q3. How is it priced?
A3. Free includes 10 forges per month across all five flavors. Pro is $19/mo for unlimited forges and saved history.
Q4. How accurate are the generated patterns?
A4. RegexProof produces a strong starting point, explains each token, and lists edge cases — but you should still test against your real inputs before shipping.
Q5. Can I test against sample strings?
A5. Yes. You can paste strings that should match and strings that should not, and RegexProof uses them to guide generation.
Q6. Who is it for?
A6. Developers, DevOps engineers, and data engineers who would rather describe the pattern than fight the syntax.
Q7. Does it explain the regex?
A7. Every significant token is annotated in plain language so you can verify the pattern does what you intended.
Q8. What edge cases does it surface?
A8. International formats, missing separators, and greedy matches that surprise you in production.
Q9. Is there an API?
A9. Pro includes saved history; checkout is handled through Waffo. Broader API access is on the roadmap.
Q10. Is RegexProof a validator?
A10. No — it is a generator and explainer. It is a developer utility, not a legal, compliance, or security auditor.
