For researchers, journalists, and knowledge workers who need more than bookmarks
Websites change, go offline, or get paywalled. Your carefully curated research library becomes a graveyard of dead links.
Highlighting in one place, notes in another, connections nowhere. Context is lost.
Tools force you into "folders" or "notebooks" when your research naturally belongs in multiple places at once.
Export is an afterthought. Your knowledge lives in someone else's walled garden.
You need a space to collect and think before you publish. Most tools force you to choose: either a clipping tool or a publishing platform.
Research that's hard to find, impossible to connect, and lost when platforms change.
Built on four core principles that respect how you actually think and work
No other bookmarking tool tracks how web pages change over time. For journalists tracking evolving stories, researchers citing sources, or legal professionals documenting evidence, this is critical.
Use case: Save an article about a political claim. Three months later, the article gets silently edited. Cirro shows you both versions with timestamps.
While Raindrop.io gives you folders and tags, Cirro creates a knowledge graph. Connect related items bidirectionally, see context in both directions, discover unexpected connections.
Use case: Link a research paper to related articles, blog posts, and your own notes. See all connections from any starting point. Your research becomes a living network, not a dead archive.
Your recipe for "Grandma's Lasagna" belongs in "Italian Recipes," "Family Favorites," "Holiday 2025 Menu," and "Public Collection." Traditional tools make you choose one location or create duplicates. Cirro lets items exist in multiple collections simultaneously.
Use case: A research paper about climate policy belongs in your "Climate Research" collection, your "Economics" collection, and your "Public Resources" collection. One item, multiple contexts, no duplication.
Recent captures (30 days) live in hot storage for instant access. Older captures move to cold storage at 1/10th the cost. You get permanent archival without the premium price tag.
Business benefit: Sustainable unit economics even for power users with 10,000+ saved items.
Whether you're building literature reviews, tracking evolving stories, or curating knowledge
Building extensive literature reviews with hundreds of sources. Track citations, preserve exact quotes, maintain context.
Tracking stories that develop over weeks or months. Preserve evidence as it was when discovered. Multiple versions of the same URL.
Saving hundreds to thousands of items with deep annotations. Building personal knowledge bases for reference and discovery.
Research-heavy writing that requires extensive source material. Keep research and writing separate but connected.
Start free, upgrade when you need more
We're building the tool that journalists use to track evolving stories, researchers use to build literature reviews, and writers use to organize sources for long-form work.
We're not building another platform. We're building better research tools.
