Screening at any scale, priced simply

Start free. Move up a plan when you need more credits.

Abstractus screens titles, abstracts, and full texts for systematic literature reviews. Share a project by email, discuss it in the Run log, and, for organizations, set whether sharing is off, limited to the organization, or open to anyone. Every plan includes Search Assist, which turns a research question into search strings, MeSH, and Emtree terms.

Questions

Can I cancel?

Yes. Your plan stays active until the end of the month you've paid for. Upgrades take effect immediately, and downgrades at the end of the month.

What is a credit?

Credits are what you spend to run screening and extraction jobs. The rates above show what one credit buys.

Do unused credits roll over?

Monthly credits don't: they reset on the 1st. Credits you buy in packs carry over and last a year.

How do organizations pay?

By bank transfer (ACH), which we recommend, by card, or by invoice with net 30 terms.

Can I get a refund?

Subscription payments aren't refunded. If a whole job fails, its credits are returned to you.
