Questions
What counts as usage?
Each turn uses what it costs to run: the model, plus any web searches, page reads, images or transcription it needs. Short questions use a little; a full round of desk research uses more. Comments and approvals on your prototypes use none. Your remaining usage is always shown in the app.
Is the Crux connector free?
Yes, on every plan, Free included. The Crux connector is the review layer for your prototypes: add it with one line, then comment on, label and approve each block, edit content and tokens in place, and track an approval plan. Setting it up and using it costs nothing. Asking Crux about your research through the MCP, from your prototype, Cursor, Claude or ChatGPT, uses usage like any other turn.
Who can review my prototype?
On Free, you. On Starter and Pro you are the one admin of your projects and can share the ones you publish with up to 5 or 10 people: approvers, who comment and give approvals, reviewers, who comment, and viewers, who look. All are free. Someone the prototype is not shared with can request access from it, and you approve them in Crux. Editors, who work in the projects with you, come with Team.
Can I try Crux without an account?
Yes. You get 3 turns with no sign-up. Create a free account to keep your work and get some free usage to carry on.
What happens when I run out?
Your plan’s usage is spent first, then any top-up balance. When both are empty, Crux asks you to top up or change plan before the next turn. Nothing you’ve made is lost.
How do annual plans work?
You pay for 10 months and get twelve months of usage, all available from the start of the year.
How does Team work?
Your team gets its own space: projects everyone on it can work in, with who wrote what shown on every piece of work. Each editor is a seat at $49 a month, with 2 to start, and each seat adds 1.5× Starter’s usage to one pool the whole team shares. Top the pool up with $50 or $100 whenever you need to.
Can my team discuss the work in Crux?
Yes, on Team. Comment on any note, finding or persona, quote the words you mean, and @mention whoever should look. They’re told in the app, and by email when they’re mentioned. Crux reads the open comments on a piece of work before it revises it.
Who can see a team’s work?
Its editors see every project. Approvers, reviewers and viewers see only the projects you share with them. Reviewers also comment, and approvers also give approvals on the prototype, so clients and stakeholders can sign off. They are free and are not seats: up to 5 for each editor.
Do top-ups need a plan?
No. Top-ups of $5 or $20 work on any account, with or without a plan.
How are payments handled?
Payments go through our billing provider. We never see or store your card number.
