Content capture and organization
Save links, notes, bookmarks, and files in workspaces with collections and tags. Add context to explain why a resource matters, rather than keeping only its URL.
Stacks
Paid
An AI workspace for individuals and teams to save, search, and share digital knowledge.
What is Stacks?
Stacks is a knowledge and content workspace that brings saved bookmarks, notes, links, and files into one place. AI search helps retrieve material using everyday questions, while a browser copilot summarizes pages and connects new material with saved resources and prior interactions.
Individuals can maintain personal workspaces, teams can use shared spaces, and creators can publish curated collections. Choose public or private collection visibility and review workspace access before sharing. Search works across the material you save and the shared resources available to you.
What can Stacks do?
Natural language search
Search saved bookmarks, notes, files, and resources available to you using everyday questions. Search examines document content as well as titles and metadata and can surface related saved items.
Browser copilot
Ask questions about supported webpages, request explanations, and generate summaries of articles, papers, or documents in the browser. Check important answers against the original material.
Context across websites
Use saved content and previous copilot interactions to connect material across websites. Review what content and context you want to retain rather than assuming every page or file should become part of a shared knowledge base.
Team collaboration
Collaborate in shared workspaces and share pages with annotations and highlights. The Collaborative plan includes roles and permissions for managing access.
Collection publishing
Share curated collections with an audience. The Creative plan includes unlimited public collections, premium collections, a branded search experience, and performance analytics.
Use Cases
“Academic research and study”
Summarize papers, clarify unfamiliar concepts, and generate study questions while connecting readings to saved research. Return to the original paper to verify key findings and citations.
“Product comparison”
Extract specifications and recurring issues from customer reviews, then save candidate products with notes for comparison across several websites.
“Team reference library”
Collect competitor research, industry articles, and working documents in shared workspaces so colleagues can find reference material and discuss it in context.
“Creator resource collections”
Gather resources around a specialist topic and publish selected collections for an audience, using the Creative plan's branding and analytics tools.
