What it does
BrainLog is a research notebook that brings notes, papers, reading, and writing projects into one workspace. Its official pages describe page-linked quotations, literature matrices, citation support, and sharing research projects. The pricing page lists a free plan with 1 GB, Storage at €4 per month or €36 per year, Researcher at €9 per month or €84 per year, Researcher Plus at €19 per month or €180 per year, and Lab at €9 per person per month billed yearly.
BrainLog is structured for researchers who want to move from reading sources to producing written work without separating notes from papers. Its product page describes research notebooks and projects; the research workflow includes reading notes with quotations linked to page locations, literature matrices, writing tools, and citations. Shared projects are also described for collaborative research.
The free tier includes up to 1 GB. Paid options include Storage, Researcher, Researcher Plus, and Lab, with the listed monthly and annual prices varying by tier and billing period. BrainLog is a specialized academic research notebook rather than a general notes app. I reviewed its product and pricing pages; I did not upload a paper or test citation output.
