Revio runs your whole systematic review in one place: screening with two reviewers and Cohen's kappa, AI extraction, risk of bias, PRISMA, and a Word manuscript. And its one unbreakable rule: every quote is verified word for word against the source article, so invented citations never survive.
No card needed. Your PDF files never leave your computer.
From the raw database export to the submitted manuscript, without juggling a screener here, a spreadsheet there, and a writing tool somewhere else.
Six things Revio does that make the difference between a fast draft and a defensible one.
Every extracted quote is matched character by character against the source PDF and stamped with its page. What you cite is what the paper says, provably.
Find papers without leaving Revio: search PubMed, Crossref, Semantic Scholar, DataCite, and OpenCitations, merge the results, and remove duplicates by DOI and title in one place.
Pool effect sizes with fixed- and random-effects models, see the forest plot, and read the heterogeneity (I², τ², Cochran's Q) — no separate statistics package.
Independent decisions, a conflicts desk, exclusion reasons, and the agreement statistic your methods section asks for, computed as you work.
RoB 2 and JBI with plain-language guidance on every domain, AI-prefilled suggestions you confirm, and the traffic-light figure ready for the manuscript.
The PRISMA 2020 flow builds from your actual screening counts and exports at print resolution, along with every chart on the analytics page.
Approved answers assemble into a structured report or a flowing draft, with front matter, limitations that name their sources, and references in APA 7 or Vancouver. Arabic translation built in.
Your PDF files are read in your browser and never uploaded. Only the specific text an AI step needs is sent for processing, and your documents are never stored on our servers. It is the way to stay inside publisher and library license terms that forbid uploading full texts to AI tools. Team sync carries decisions and notes, never your documents.
Credits meter the AI: a question or a drafted answer uses 10, processing a full article uses 20 to 60 by length. Everything else, screening, reviewing, exports, and team sync, is unmetered on every plan.

Start with the trialOne shared pool of 5,000 credits per seat for the whole team, one payer, an invite code for colleagues. Minimum 2 seats.
Create your accountA typical 40-study review uses roughly 2,000 credits: about 40 full-text extractions and 40 questions across the evidence. That sits well inside one month of Pro, and if a heavy month runs low a $5 top-up adds 1,000 credits that never expire. Screening, reviewing, risk of bias, the PRISMA diagram, and every export are never metered and never stop. No step ever spends a credit without showing you exactly what it did.
Most reviews take three to six months. Revio is billed monthly and cancels the day you submit, so you pay only for the months you actually work: no annual lock-in and no per-review fee.

Most researchers stitch a review together from a screener, a separate AI extractor, and a manuscript tool. Revio is the one workspace that carries a review from import to a submitted manuscript, with every quote checked against the source.

Comparison reflects each tool's publicly listed features and standard plans as of 2026. Vendors change their offerings, so check their sites for the current details. Revio is not affiliated with, or endorsed by, any product named here.
On your computer, and nowhere else. Revio reads them in your browser; the only things that ever touch a server are the AI requests and, if you turn on team sync, the small collaborative layer: decisions, notes, and edited answers. Articles and evidence travel in a project file you keep and share yourself.
A unit of AI work, priced by size on the server: asking a question or drafting one answer uses 10, a risk of bias prefill or an audit uses 20, and processing a full article uses 20 to 60 depending on its length. Failed calls refund themselves. Screening, reviewing, analytics, and every export cost nothing.
One person starts a Lab plan and shares its invite code; everyone's AI use draws from one pooled balance. Teammates load the same project file and flip on Live sync, and from then on decisions, notes, screening calls, and bias judgments merge in real time, newest wins, every conflict listed.
The complete product, capped at 4 articles and 250 credits: enough to import, screen, process, verify quotes, appraise bias, see your PRISMA, and export a Word report before paying anything.
Any time, from Manage billing inside the app; payments run through a certified payment processor and Revio never sees your card. Yearly plans simply run out their term. Top-up credits never expire, even with no subscription.
Elicit is excellent at searching the literature and pulling data from papers. It is not a systematic-review workflow: there is no dual-reviewer screening with an agreement statistic, no RoB 2 or JBI appraisal, and no PRISMA pipeline into a manuscript. Revio is that pipeline, and every quote it keeps is verified word for word against your PDF.
They manage screening well. Revio takes the same review all the way to a formatted Word manuscript: extraction, risk of bias, PRISMA, and references, with AI extraction that is not locked behind an institutional license, and monthly billing you can cancel when you submit.
Yes, with transparency. Journals ask you to disclose AI assistance and to have a human verify the output. Revio is built for exactly that: every drafted answer is approved by a named reviewer with a timestamp, and every quote is checked against the source, so your methods section can state that all AI output was human-verified.
Revio was built by a physician who could not justify hundreds of dollars per review for software that only screens. So it does the whole review, keeps your PDFs on your own machine, and is priced for people paying out of their own pocket.
