Histre

Histre is a knowledge system that automatically organizes web research, ideas, and team knowledge, with annotation, highlighting, collections, summarization, search, and sharing. Free trial covers notes and collections; the $7 per user Pro plan adds AI features, unlimited research history, advanced search and team collaboration.

Histre is a knowledge system built around the problem of scattered information. Browser tabs pile up, bookmarks get forgotten, team chats bury decisions, and AI conversations vanish once the window closes. Histre's pitch is that it automatically organizes what you capture, then gives you annotation, highlighting, collection, summarization, search, and sharing tools on top of that organization. The site frames the product as a personal and team knowledge layer rather than another note app. Research is the clearest example of how it works in practice. Histre tracks the research your team does on the web, keeps the surrounding context, and can build comparison tables from what has been gathered. That turns a messy trail of pages into something closer to a decision record: explore, filter, decide. For individuals the draw is keeping internet research and ideas in one place instead of losing them across open tabs and bookmarks. For teams the draw is shared context, so knowledge does not stay locked inside one person's browser. Histre sells itself to people who do a lot of web research and to teams that need tribal knowledge to survive turnover. The pricing page splits a free trial tier (unlimited notes and collections, 7 days of research history, 30 days free) from a Pro tier at $7 per user per month, which adds AI powered features, unlimited research history, advanced search, advanced integrations and org / team collaboration. The AI angle is therefore partly a paid add-on rather than a free default. Alternatives in this space tend to fall into two camps: bookmark and read-later tools that organize links but stop there, and note or wiki tools that require you to do the structuring by hand. Histre sits between them, betting that automatic capture plus light annotation beats manual filing. The privacy promise on the homepage is explicit: no selling data to third parties, deletion available, and a written privacy policy. Worth a look if your research workflow currently lives in spreadsheets and dozens of open tabs.
