What will never be behind a plan
Two of these are load-bearing rather than generous, and it is worth saying why while nothing depends on it.
- Archiving, and re-checking
- If the archive were paid, a free user's claims would be less checkable than a paying user's. That is the opposite of the product. Every source anyone cites is captured and watched, on every plan.
- A publisher's right of reply
- There is no site-owner veto here. What a publisher gets instead is the right to answer, attached to the citation. Charging for that turns “publishers may answer” into “we sell publishers the right to answer”, and that sentence loses the argument the whole position rests on.
- A verified badge, at any price
- There will not be one. A paid mark that reads as credibility is a truth score with a price on it, and there is no version of that this site can sell.
- Advertising, at any volume
- Not a tier, not a downgrade, not ever. The reason is the whole of the essay.
Students
Managed accounts, created by a school or organisation, are free. They also cannot reach the AI features or receive money at all — enforced in the database rather than in the interface. A paywall is not going to be the thing that keeps a classroom out.
Why any of this exists at all: Why Critically.
