What happens when I run out?

Medawar tells you before starting a review it cannot cover and offers a top-up pack or a bigger plan. Nothing is charged automatically beyond your subscription and the packs you buy.

Plans and review credits

What uses credits

A full review: 11 credits, less than its checks one by one.
Selected checks: the sum of their credits, never more than 11.
Extracting a paper on its own (medawar extract): 1 credit.
Uploading a paper in the web app: no credits (it needs an active plan).
Chat messages, questions about a paper and related papers use the chat token allowance, not credits.
Fix, which rewrites the paragraph a finding is about into a new revision, uses chat tokens too: about 2,000 tokens a fix.

If a review fails on our side, its credits are returned.

A check on its own costs, by how much work it takes:

Language: 3 credits.
Acronyms, References: 2 credits each.
Title, Abstract, Keywords, Authors, Headings, Structure, Figures and tables, Statistics, Ethics, Funding, AI signals, Literature coverage: 1 credit each.

Expert reviews

An expert review is read by independent human reviewers in your field, double-blind, over several weeks, and does not use review credits. The Max plan includes one per billing period (unused ones do not roll over); on Pro, and on Max beyond it, each is a one-off payment shown before you confirm. The trial does not include expert reviews.

Top-up packs

Ran out before the period ends? Any account, the trial included, can buy a pack of review credits or chat tokens, with one payment and no subscription:

50 review credits: $29.
200 review credits: $99.
2M chat tokens: $15.
10M chat tokens: $59.

A pack stays valid 12 months from purchase, across billing periods. It is used only once your plan's allowance for the period runs out, the oldest pack first. Credits a failed review gives back return to where they were taken from. Without a plan, packs still work until they are used up. Buy one from the pricing page; your account page shows what is left of each pack and when it expires.

Renewals and cancelling

Credits and chat tokens included in a plan reset at the start of each billing period; unused ones do not roll over (packs keep theirs). You can upgrade, change card or cancel from your account page. A cancelled plan stays active until the end of the period you paid for.
