FAQ
Pricing questions, answered.
Is the Free plan really free forever?
+
Yes. You can generate up to 3 architectures and 3 contract audits per day with no time limit and no credit card required. We keep the Free tier permanently available because we believe expert-level blockchain tooling should be accessible to every builder.
When does the Pro plan launch?
+
We are finalizing payment infrastructure and saved-history features. Pro is targeting public launch within the next quarter. Drop your email below to be notified the day it goes live — early subscribers will receive launch pricing locked for life.
What counts as one architecture or one audit?
+
One architecture generation = one prompt submitted to the AI Architect tool (regardless of how many levels — Context, Container, Component — are rendered). One audit = one contract submitted to the AI Auditor. Re-runs of the same prompt count separately.
Can I export my diagrams and audit reports?
+
Free plan: download interactive HTML, static PNG, and inline SVG of any diagram, and export audit reports as plain text. Pro plan: adds PDF (print-ready with header/footer), raw JSON for programmatic use, and persistent saved history accessible from your dashboard.
Do you offer custom enterprise pricing?
+
Yes. Teams needing dedicated rate limits, SSO, audit log access, or a private deployment can email contact@blockhertz.com. We tailor enterprise contracts to your security and volume requirements.
What happens to my data?
+
Free plan: prompts and contract code are processed by Claude and not stored on our servers beyond what is needed for the immediate response. Pro plan: optional saved-history is encrypted at rest and tied to your account; you can delete any entry at any time. We never train models on your input.
