The owner pays.
Everyone invited writes free, forever.
Papers are written by groups, so pricing that charges per co-author punishes collaboration, the one thing this tool exists for. Here, one person (usually the PI or the corresponding author) carries the project, and every student, co-author and outside collaborator they invite gets full access at no cost. No collaborator caps, ever.
Every new account starts with 3 months of Researcher, free.
No card. Each collaborator who joins a paper you own adds a month, up to 3. When the free months end, you choose: Researcher, or the Free plan, which keeps one active paper you own and every paper you're invited to. Nothing is deleted and nothing is locked away. Accounts from early access keep 50% off their first year.

Straight answers
Why is it free for people I invite?
Because the value of this tool is what happens between co-authors: the argument that's still attached to the assumption, the Catch Up after two weeks away. A paywall in front of your collaborators would kill exactly that. The person who owns the paper decides to pay once; nobody else ever hits a wall.
What exactly is the AI allowance, and what happens if I hit it?
One AI action is one press of an AI feature: a Catch Up briefing, a thread summary, a compile diagnosis, a reviewer-comment import, a drafted response paragraph. Paid plans include 500 actions per person per month; for scale, our heaviest real users do about 300. We publish the number instead of saying 'unlimited' because unlimited AI is a promise nobody selling it can keep honestly. If you do hit the ceiling, nothing breaks and nothing charges you extra: AI features switch to the free built-in helpers until the 1st, and a note tells you why. Need more? Plug your own API key into a project and pay your provider directly; that path has no ceiling from us. Papers, collaborators, compiles, exports: those are unlimited, full stop.
Can I keep a manuscript away from the AI entirely?
Yes. Any paper can switch the AI off in Settings → AI, and then nothing from that paper is ever sent to a model. With AI off, the paper still remembers everything and still briefs you; it just won't write anything for you. Catch Up, the reviewer tracker and compile help keep working from the record, while Ask the paper and AI drafts are unavailable. The other direction works too: a paper can run on your own API key with your own provider, which nobody here can read, never counts against the allowance, and has no ceiling from us. The plan price is the same either way: you're paying for the workspace and its memory, not for the model.
What is a Lab member, and who counts?
A member is someone the lab puts on the plan: up to ten people, each with everything a Researcher has: unlimited owned papers and their own AI allowance. Everyone a member invites to a paper is a co-author, not a member, and co-authors never count and never pay. So a ten-person lab pays $499 a year however many collaborators its papers have; the eleventh member costs $35 a year. If only one person in the group needs to own papers, a single Researcher plan already covers the other nine as free co-authors.
How do the free months work?
Every new account starts on the Researcher plan for 3 months, free, with no card. Each collaborator who accepts an invitation to a paper you own adds a month, up to 3 (one month per person, however many papers they join). When the months end you pick Researcher or Free. On Free, the paper you created first stays active and the others are paused: you can still read, edit, discuss and export them, but not compile or update them from files, until you archive down to one active paper or upgrade. Upgrading brings every paused paper back at once. You get an email a week before and the day before.
What happens to my free paper when I start a second one?
You'll be asked to upgrade to own a second active paper, or to archive one first; that's the whole business model. Nothing you own is ever held hostage: the export button works on every plan, every day, and your first paper keeps working.
I'm a student.
The free tier is the full product for your first paper, papers you're invited to don't count against anything, and the free months apply to you like everyone else. If your supervisor runs the paper on a Researcher or Lab plan, you never pay at all.
Can I get my work out?
Always. Any project exports as a plain zip of LaTeX files at any time, and you can delete your account and its data from inside the app. Your manuscripts are yours.
