I've found this to be the best for identifying statistical and methodological issues.
A remarkable review of a complicated paper, especially noteworthy for the depth of the methodological comments. I do not often see reviews by statisticians that are as detailed.
I've tried other AI tools aimed at improving science, but this was my first experience with something like this, and it feels truly different… it actually challenges you and helps you grow as a scientist.
90%of our users rate the outputs as equal to or better than human peers.
An evaluation for science.
Most quality signals arrive too late to act on, but the Calibre score doesn't. A 0-100 number broken down by where the work is strong and where it needs revision. So you have the specifics to improve, and see the weak points before a reviewer does.
What a Calibre score measures.
Allignment of design and question.
How well your study's approach can actually answer the question it sets out to ask.
Statistical and analytical soundness.
How well the analytical work behind your results - statistics, models, reasoning - holds up.
Conclusions sized to the evidence.
How well your claims are matched to the data behind them, measured against the standards of your field.

Three unique elements.
A mixture of models, better than any one.
Every frontier model orchestrated: Claude, GPT, Gemini, Mistral, Grok, alongside our Explorer One model. Single-model bias removed by design.
An in-house science stack, scaling discovery.
The scientific method, automated with durable memory, verification at the source, and drawing from external data, not an LLM talking to itself.
Scientific agents that think like the field.
Enhanced with principles from human cognition to reason and act like scientists do. Specialised with tools, dynamically constructed to meet task complexity. Built and proven to do science.
The architecture underlying our tools runs science autonomously.See research →
