most note apps store what you write. crosmos helps you find what matters.

we write thousands of notes, ideas, tasks, fragments of thought. but when it’s time to recall something important, it’s buried somewhere you can’t reach.

search is slow. context gets lost. and tools built for “storage” fail when you actually need clarity.

crosmos takes a different approach, a fast, local-first knowledge engine designed to help you think, not just take notes.

the problem

most note apps are passive. they collect information, but they don’t help you use it. your ideas sit in folders, pages, and databases that don’t understand meaning or relationships.

and everything lives behind cloud accounts, sync issues, and lock-ins you can’t escape.

the solution

crosmos is built to make your knowledge actually accessible.

a local SQLite engine powers instant search, semantic recall, and agentic workflows. your notes become discoverable, navigable, and truly yours.

what makes crosmos different

built for speed

crosmos opens in milliseconds. no heavy runtimes, no browser layers, no RAM-hungry frameworks.

powered by tauri + rust, everything feels immediate, from switching notes to running searches.

the app stays lightweight as well

your knowledge stays on your machine

crosmos respects data-ownership and hence it is local-first. your entire workspace, notes, blocks, tags, search indexes lives inside a single SQLite database.

  • back everything up by copying one file
  • move your knowledge to another device instantly
  • delete it completely by removing one folder

no forced cloud sync. no subscriptions to access your own data.

made for thinking, not just storing

crosmos uses a clean, block-based editor designed for clarity and flow.

  • slash commands that feel natural
  • AI blocks that help you speed up writing
  • chat that understands your notes
  • semantic search that finds meaning, not just keywords

and soon: MCP integration, get things done without leaving your workspace.

the vision

we don’t need another “second brain.” we need a tool that makes our own brain faster to explore, iterate, and create without friction.

crosmos is a place where your ideas stay alive. where search becomes recall. where your notes grow with you.
