The honest answers

Pricing questions, answered.

What's actually in Free?

Three foundational tools that ground an AI agent in your codebase: Index (the local knowledge graph the agent queries), Code Search (five modes, symbol, path, content, regex, semantic), and Code Read (symbol slice, file overview, full file). All 26 languages. macOS, Linux, Windows. No signup, no email, no card. Free for ever.

How much is Pro and what is the trial?

Pro is $29.99 USD per month. There's a 14-day free trial, no card up front, every Pro feature unlocked. Start it from the install page or via `twira login`. At day 14 you choose: pay for Pro, or drop back to Free (Graph code intelligence). Nothing breaks; you just lose the Pro features.

I'm a student. How do I get Pro free?

Register with an institutional email address: a .edu address or a recognised equivalent in your jurisdiction. Pro unlocks at $0 under the Education licence in the EULA. We re-verify the address once a year; as long as it's still active and tied to a recognised institution, the licence continues. Use it for coursework, research, supervised projects, or contributions to public open-source. Paid consulting work alongside studies is not Education Use; that needs a paid Subscription.

What happens if I cancel Pro?

You drop to Free, Index, Code Search, and Code Read stay unlocked. The Pro features lock; the data they built for you stays. Audit chain, lore, indexes, masterplan history, all of it sits on your machine, exactly as you left it. Re-subscribe any time and pick up where you stopped.
