What It Is

Cosense, formerly Scrapbox, is a team knowledge-sharing and collaborative documentation tool from Helpfeel Inc. It is positioned as a way to turn individual and team experience into connected, reusable organizational knowledge. The product emphasizes fast writing, page linking, and collaborative editing, making it suitable as a knowledge base, R&D notes space, project documentation tool, and repository for accumulated know-how.

Core Features

At its core are bidirectional links and two-hop links: once a page is linked, backlinks are displayed automatically, and second-degree related pages are shown in the footer to help users discover context between pieces of knowledge. It also supports quick outlining, real-time collaborative editing, line-level links, media paste and embedding, link autocompletion, full-text search, presentation mode, a sketch board, and developer-oriented features such as code highlighting, mouse-free editing, CSS, and Userscript. On the admin side, it offers public/private projects, role-based access control, Google/G Suite SSO, Slack integration, and recent edit notifications.

Pricing

Public projects are free. Personal, educational, and non-profit use is also free, with unlimited pages and members. Commercial private projects are paid, priced at ¥1,100 JPY per user per month, with unlimited pages and members. The first 100 pages can be used for free; inviting every 10 additional members adds another 100 free pages, up to a maximum of 300 pages. Multi-project usage may be billed by users multiplied by the number of projects, and projects with more than 200 users can contact the company for discounts.

Pros and Cons

Its strengths include powerful knowledge-linking capabilities, a low barrier to writing, and a free policy that is friendly to public projects, education, and individual users. It also includes enterprise features such as SSO, access control, SSL/TLS encryption, and Slack integration. The downsides are that publicly available information does not clearly specify API support, import/export options, mobile apps, SLA, or data residency choices. Costs may also rise for commercial use across multiple projects, and support appears to rely mainly on help documentation and a contact form.

Who It’s For

Cosense is a good fit for R&D teams, research groups, creative teams, educational communities, non-profits, and companies that want a lightweight way to capture experience and build an internal knowledge network.
