Tau Square Studio · Only for our students
Your whole meta-analysis.
Your whole meta-analysis.
One workspace.
Studio takes you from search results to a submitted paper in one place, with guardrails at every step. So you do more meta-analyses, faster, without the mistakes that sink papers.
Every Tau Square student gets Studio Basic with their course. Studio Premium adds AI features that do the slow parts with you, so you finish each review faster.
The usual way
One review. Six tools.
One review. Six tools.
A hundred places to slip.
So here's how most students run a meta-analysis today: screening in one app, extraction in a spreadsheet they built themselves, risk of bias on paper forms, the analysis in a program they're still learning, the PRISMA diagram drawn on a slide, and a co-reviewer's work arriving by email. Every hand-off is a chance for a number to change on its way. And that one wrong number is the one a peer reviewer finds.
Before: six tools, hand-offs everywhere
Numbers copied by hand between them, again and again.
With Studio: one workspace
- Import and remove duplicates
- Screen, blind, with a partner
- Full texts, fetched and matched
- The coding sheet, locked
- Extraction, with sources
- Risk of bias and certainty
- The analysis, in real R
- The write-up pack · ready to submit
Every number travels by itself: from the paper, to your sheet, to your forest plot.
One workflow
Every step of the review,
Every step of the review,
in the order you learned it.
Studio follows the 100-Hour Protocol step by step. Each step hands its work to the next, so nothing is retyped and nothing gets lost.
-
Step 1
Import, and duplicates gone
Bring in your results from PubMed, Embase, Web of Science or any database that exports RIS or CSV. Duplicates are found and set aside, never deleted.
Kills: the afternoon lost to cleaning a messy library.
-
Step 2
Screening, blind and fast
Keyboard shortcuts, a calibration round before the real thing, and agreement (kappa) measured for you. The PRISMA flow draws itself as you go.
Kills: screening that drags on for weeks.
-
Step 3
Full texts, found for you
Free full texts are fetched for you. Drop the rest into a folder and Studio matches each PDF to its study. Retracted papers are flagged, and one trial published twice is caught.
Kills: the PDF chase, and counting one trial twice.
-
Step 4
The coding sheet, built and locked
Your extraction sheet is built from your protocol and the outcomes your papers actually report, the Divergent Data Extraction Protocol way. Approved, versioned and locked before extraction starts.
Kills: changing your sheet halfway and redoing everything.
-
Step 5
Extraction: verify, don't type
With Studio Premium, every value your sheet needs is found and highlighted for you, so you confirm it with a keypress instead of typing it. Two extractors, compared and reconciled.
Kills: typing hundreds of numbers by hand, and the typos that come with them.
-
Step 6
Risk of bias and certainty
RoB 2, ROBINS-I, Newcastle–Ottawa, QUADAS-2 and AMSTAR 2, with each tool's own rules applied for you. Traffic-light plots, and a GRADE summary of findings.
Kills: bias tables that don't match your own judgements.
-
Step 7
The analysis, in real R
Point and click, on R and metafor, the package behind thousands of published meta-analyses. Forest and funnel plots, subgroups, meta-regression, sensitivity analyses, and the R script that reproduces every number.
Kills: the fear of code, and results you can't reproduce.
-
Step 8
The write-up pack
Your Methods and Results drafted from what you actually did, with references. The PRISMA 2020 diagram, the summary-of-findings table, an AI-use statement and a full audit trail.
Kills: writing your methods from memory, weeks later.
Meet Tau, the face of Tau Intelligence.
Studio Premium · AI featuresThe slow parts, done with you.
Your review, done sooner.
Studio Premium adds AI features to Studio. They take on the hours you'd spend hunting through PDFs, mapping outcomes and copying numbers, so your time goes on the decisions only you can make.
Faster
Hours back on every review
Your full texts set up and checked against your criteria, every outcome mapped and every value your sheet needs found for you. The reading that fills weeks of a review moves at your pace, not the paper's.
Easier
No hunting through PDFs
The answer is already highlighted in the paper. Check it, confirm it with one keypress, move on. You stay sharp to the last paper, not just the first.
Safer
Every number you can defend
Nothing enters your data until you confirm it, and every value leads back to its page in the paper. When a peer reviewer asks where a number came from, you show them.
No made-up numbers in your data. A value that isn't in the paper can't slip into your analysis.
Where Studio Premium saves you hours
- Every full text checked against your eligibility criteria, ready for your decision and never swaying it.
- Every outcome in every paper mapped, so your coding sheet starts complete.
- Every value your extraction sheet needs, found and highlighted for you to confirm.
- The facts behind risk of bias gathered for you: randomisation, concealment, the losses in each group, and trial registration.
You stay in charge of every judgement: Studio Premium never calculates your results or decides risk of bias for you. And because journals ask you to disclose AI use, Studio writes your AI-use statement for you.
Guardrails
Guardrails that catch
Guardrails that catch
what reviewers catch.
Studio won't let the classic mistakes through. When something's wrong, it stops you and tells you why, and if you have a good reason to go ahead, your reason goes on the record.
- Blind screeningNeither of you sees the other's decisions until you've both finished.
- Calibration firstA practice round on the same records, before the real screening starts.
- Agreement, measuredKappa on blind decisions only. If extraction agreement drops below 0.8, the Red Light protocol starts.
- Nothing unverifiedNothing reaches your analysis until a person has checked it.
- A locked sheetExtraction starts only after the coding sheet is approved and locked.
- Safe poolingNo pooling with fewer than two studies, and no funnel plot with fewer than ten.
- Number traps caughtA standard error typed as a standard deviation, a shared control group counted twice, randomised and non-randomised studies pooled together.
- A full audit trailEvery decision, who made it and when, kept for good.
The course and Studio
Learn it in 100 hours.
Learn it in 100 hours.
Then keep going.
A systematic review has been measured at about 1,100 hours of work.1 The course and Studio are built to get yours done in under 100. The course teaches you the method, step by step, on your first meta-analysis. Studio is that same method built into software: the same steps, in the same order, with the same rules as the playbooks. So the next one doesn't start from zero. You already know what every step means, and Studio does the fetching, the typing, the formatting and the drawing. You do the thinking.

The playbooks, built in
- The Divergent Data Extraction Protocol becomes your coding sheet, with its tabs, its naming and its golden rule: missing means blank.
- The GIGO Protocol becomes your risk-of-bias and certainty steps.
- R-MetaScript becomes the R script you download with your analysis.

Your team
Bring your co-lead.
Every Studio plan, Basic included, comes with one co-lead: the research partner who screens and extracts alongside you. Your co-lead works inside your reviews with you (with the AI features too, on Studio Premium), and every two-reviewer rule in the protocol is covered by the two of you.
Your co-lead must be a Tau Square student too, and can't start reviews of their own. That's what their own Studio plan is for.

Questions
Studio, answered.
Is Studio included in the course?
Yes: every Tau Square student gets Studio Basic with their course, at no extra cost: the whole workspace, with every step done by hand. Studio Premium (Plus, Pro or Pro Max) adds AI features that do the slow parts with you, so you finish faster. It is sold separately: add it at checkout when you join, or later from your dashboard.
If Studio Premium does the slow parts, will I still learn to do it myself?
Yes. The method is the same on both plans, and so are the skills you learn: choosing what to extract, judging risk of bias and making sense of the results. Studio Premium just takes the slow parts off your plate, with up to 90% less time spent on them and automated checks on every number. Every decision is still yours. Want to do it all by hand first? Studio Basic has every step and comes with your course, and you can add Premium later from your dashboard. See one step done both ways.
Can I buy Studio without joining the academy?
No. Studio is only for Tau Square students. It's built on the Tau Square Academy method, and it stays that way.
What is Tau Intelligence, and can I use it for published research?
Tau Intelligence is everything inside Studio: the checks, the guardrails and the features. Studio Basic comes with your course, and Studio Premium adds AI features that do the slow reading of your review with you, so you finish faster. And yes, you can use them for published research. Nothing enters your data until you confirm it, every value leads back to its page in the paper, and Studio writes the AI-use statement journals ask for.
Where are my reviews kept?
Your own reviews are kept in a folder you choose on your computer, with a working copy in your browser. A review you run with a team is also shared through Tau Square's servers, so everyone on it stays in step: each person gets only what they may see, and full texts go to your team only if you choose. Studio runs in Chrome or Edge on a laptop or desktop.
Who can work on my reviews with me?
You and one co-lead, who must be a Tau Square student too. Your co-lead screens and extracts alongside you, with the AI features too on Studio Premium, but can't start reviews of their own. You can also invite other people to screen, extract and assess risk of bias in your review, without the AI features: up to 4 people on a review, you included, on every plan.
How many Tau Intelligence credits do I get?
AI features come with Studio Premium: 300 credits a month on Plus, 900 on Pro and 1,500 on Pro Max. Studio Basic has no AI features, so it has no credits. AI features use credits as they read your papers: usually one credit for a paper of up to about 30 pages, and more for a longer one. A paper uses its credits once a month, however many times it is read.
Does anything renew automatically?
Your course doesn't: it's a one-time payment. In India, Studio Plus and Pro by the month renew until you cancel, and a 12-month or 2-year plan carries on month by month when it ends, once you approve renewal (₹5, which Razorpay refunds). Pro Max, and every plan outside India, doesn't renew by itself yet: you add it again from your dashboard when it ends. Cancel any time from your dashboard: you keep the time you've paid for, and then your reviews carry on in Studio Basic.
What happens when my Studio plan ends?
When Studio Premium ends, your reviews carry on in Studio Basic, without the AI features. Your reviews always stay in your folder, and you can open and export them.
