Use tool ↗About Cluing
Cluing lets a team highlight text from web pages and PDFs through a browser extension, then organizes those highlights into a shared knowledge base instead of leaving them scattered across bookmarks and documents. On top of that captured knowledge, users can run agents to draft things like SEO posts, dashboards, and reports grounded in what the team has saved. It targets content marketers, researchers, consultants, and founders who need a team's collective research to stay searchable and reusable rather than trapped in individual browser tabs. The free plan caps users at 5 clusters and 5 guests; paid plans add more AI models, agent seats, and monthly automation credits. The operating company, Collabwriting Inc., is based in Dover, Delaware.

Pros & cons of Cluing
Cluing solves a specific problem — a team's research and highlights scattering across browser tabs and personal notes — by routing everything into one shared, searchable base that its agents can then draft from. It is most useful once a team is actually capturing enough material for the organizing and agent features to pay off; below that, the free plan's 5-cluster cap will feel tight fast.
Pros
- Browser extension captures highlights directly from web pages and PDFs
- Free tier is usable enough to evaluate the core workflow before paying
- ISO/IEC 27001:2022 certification is a real signal for teams with security requirements
Cons
- Free plan's 5-cluster and 5-guest limits are restrictive for anything beyond a quick trial
- Team plan jumps to $140/month, a large step up from the $12/month individual Pro plan
- Value depends on a consistent team habit of highlighting and organizing, not just occasional use
Best for
- Small research or content teams who highlight a lot of web and PDF material
- Consultants and founders who want shared institutional knowledge instead of individual notes
- Teams that want to turn saved research directly into drafts like SEO posts or reports
Not for
- Solo users who just want a simple personal bookmarking tool
- Teams that need more than 5 shared clusters without upgrading immediately
