Bottom line
Refine.ink is the specialist for econ theory and formal proofs. Fukurō is the generalist for experimental and empirical work across disciplines, at a fraction of the per-review cost, with rebuttal and version comparison on Professional. Theory authors may use both: Refine.ink for logic depth, Fukurō for the full 32-dimension reviewer read.

- No citation DB verification or figure analysis
- No rebuttal or manuscript version comparison
Key limitation: Niche audience. $49.99 per single review. No life-sciences focus. No rebuttal or version comparison workflow.
Frequently Asked
Is Refine.ink worth $49.99 per review?
For theory-heavy manuscripts where logic depth matters most, Refine.ink's niche focus can justify the price. For most empirical papers, Fukurō at $2.99–$1.60/review covers more reviewer dimensions at lower cost.
Can I use both tools?
Yes. Many theory authors run Refine.ink for proof-level critique and Fukurō for structure, methodology, clarity, and citation checks across 32 dimensions.
