Utilities Pro Pro

SpecStudio stays free for everything you use today. Pro adds the features built for shipping AI work with confidence, in all four DevSpeak Utilities apps, for one price.

7-day Pro trial, no card required

Sign in with Google and it starts by itself: every Pro feature in all four apps, with up to 30 Pro actions a day (100 in total) and 3 premium-model runs a day (5 in total). Then you're back on Free automatically; nothing to cancel.

One trial per email. Not available to emails that already had Utilities Pro, and new trials are limited each day.

Pro in SpecStudio

  • Spec risk audit (OWASP LLM Top 10) · Score every spec 0-100 against the OWASP Top 10 for LLM Applications 2025 (prompt injection, sensitive data, output handling, excessive agency, unbounded consumption), with the evidence and a concrete fix for each finding.
  • Export to AGENTS.md, CLAUDE.md and Cursor rules · Render a validated spec as AGENTS.md, CLAUDE.md and a Cursor rule (.cursor/rules/*.mdc), ready to copy or download, regenerated from the spec so they never go stale.
  • Live page grounding · Ground a spec in the live content of the page the agent will operate on, read server-side and passed to the model as untrusted reference data, never as instructions.
  • Premium models · The large models in every model picker: Claude Opus 5.5, Claude Sonnet 5.5, Mistral Large 4 and Mistral Medium 3.5. Claude Haiku 5.5 (the default), Mistral Medium 3.1, Devstral 2, DeepSeek and the other fast models stay free for everyone.
  • AI writing assist in the editor · Rewrite, tighten, fix, expand or turn any selection into a checklist.
  • Cloud version history · Every save kept in the cloud, with a side-by-side diff and one-click restore.
  • HTML and PDF export · Share polished documents with stakeholders who never open a Markdown file.
  • Token and context budget · See how much of each model's context window a document uses before you paste it.
  • Pro template pack · Seven ready-made specs: checkout QA, listing extraction, multi-step forms with approval checkpoints, accessibility and account-settings audits, price monitoring and inbox triage.

Secure checkout by Dodo Payments, merchant of record. Prices include applicable taxes. Cancel anytime from Settings → Billing.
