Hjarni vs Context Cloud

Context Cloud stores typed memory chunks for engineering teams. Hjarni is a shared Markdown knowledge base your team and their AI tools read and write.

Free to start. No credit card required.

Quick answer

Context Cloud is an MCP memory server for engineering teams: shared workspaces of typed knowledge chunks, hybrid retrieval, role-based access, automatic deduplication, and support for Claude, Cursor, Codex, Windsurf, and ChatGPT. It is free today. Hjarni is a shared Markdown knowledge base with a built-in MCP server that ChatGPT, Claude, Cursor, and 20-plus MCP clients read and write, plus a web editor and mobile apps, with per-folder roles, per-edit attribution, and one-click revert. Pick Context Cloud if you want a typed chunk store tuned for agent recall inside coding tools. Pick Hjarni if you want team memory that is also readable documentation: notes people open, edit, and export as plain Markdown.

Memory a human can read

A Hjarni note is a document: it doubles as team documentation. Context Cloud's chunks are typed entries (decisions, findings, conventions) you browse and curate in a dashboard, built for agent recall first.

Search

Context Cloud runs hybrid retrieval (vector plus BM25) that can match by meaning. Hjarni's plain-text index is the same one behind the UI, REST, and MCP, so what you can see is what you can search, in any language.

Plain Markdown you own

Hjarni notes export as a Markdown ZIP anytime; the export is the source format. Context Cloud's unit of storage is the typed chunk, not a file you take with you.

Two answers to the same team problem

Both products exist because assistant memory is personal. Claude Code, ChatGPT, and Cursor each remember things for one person, so an engineering team's context stays trapped in individual sessions. Shared team memory is one of the most-requested features on the Claude Code issue tracker, and both Hjarni and Context Cloud answer it the same structural way: put the memory outside the assistant, behind an MCP server every teammate connects to.

From there the two products diverge on what memory is. Context Cloud stores typed knowledge chunks: each is a typed entry (a decision, finding, convention, or piece of state) with an author, which drives hybrid retrieval and automatic deduplication of conflicting or stale context. Hjarni stores Markdown notes in folders: documents with titles, tags, wiki-links, and a revision history, organized the way a team wiki is.

About the "only MCP memory server with shared workspaces" line

Context Cloud markets itself as the only MCP memory server with shared workspaces, RBAC, attribution, and cross-tool support. Read that as a description of the chunk-store category, not the landscape. Every item on that list ships in Hjarni today: team workspaces as shared folders, per-folder roles, per-edit attribution that names the person or the specific assistant, and one hosted MCP server that Claude, ChatGPT, Claude Code, Cursor, and other clients connect to. The category is young and claims move fast on every side, ours included. The practical takeaway is simply that shared team memory over MCP is a choice between shapes, not a single vendor.

Chunks are for agents. Notes are for agents and the people who manage them.

Memory your team can read is memory your team can trust

The deep difference is what happens when a human needs to look at the memory. A chunk store is built for agent recall: the dashboard shows you typed entries, hybrid retrieval does the search, and automatic deduplication manages contradictions. That is a real engineering feature set, and Context Cloud has a web dashboard to browse and curate it. But the unit is still a chunk. When a new hire asks where the deploy runbook is, or a lead wants to review what the agents have been writing all sprint, a folder of documents reads more like the wiki they expect.

A Hjarni note is a document. The deploy runbook is a page a person opens, reads, and edits, and the same page is what every teammate's assistant cites. Every edit is a version attributed to a person or a named assistant, with a diff, a one-click revert, and a recoverable Trash behind it. Your team memory doubles as your team documentation, so keeping it honest is a reading job, not an audit job.

Search follows the same philosophy. Context Cloud's hybrid search, vector matching fused with keyword ranking, can match by meaning across thousands of chunks, which is genuinely useful. Hjarni's search is plain-text over Markdown: less clever, but transparent. It is the same index behind the app, the REST API, and the MCP search tool, it works the same in any language, and what you can see in the app is exactly what your AI can find.

When Context Cloud is the better fit

If your team's memory is meant to be consumed mostly by agents inside coding tools, and you want typed entries, hybrid recall, and automatic deduplication of stale context, Context Cloud is built for exactly that. Teams standardized on Claude, Cursor, Codex, and Windsurf who think of memory as infrastructure rather than documentation will feel at home. It is free today, so trying it costs nothing; check its export options before you commit a team's knowledge to any store, theirs or ours.

When teams choose Hjarni instead

Teams pick Hjarni when the memory should serve people too, not only agents. It is a full knowledge base you write in directly: a web editor, iOS and Android apps, and a REST API alongside the MCP server, all EU-hosted. The notes your agents read are the wiki your humans read. Folder instructions tell every assistant how to behave in each space. And the exit is always open: notes are plain Markdown, exportable as a ZIP, so a roadmap change on anyone's side cannot trap your team's knowledge. Sharing is asynchronous, like a wiki, not live co-editing, and that is the grain decisions and runbooks actually want.

When to use Context Cloud

  • Your memory is consumed by agents in coding tools, not read by people
  • You want typed chunks, hybrid recall, and automatic deduplication
  • Your team lives in Claude, Cursor, Codex, and Windsurf, and free is the priority

When to use Hjarni

  • You want team memory that is also readable team documentation
  • People write and read notes directly, on web and mobile, not only via a coding tool
  • You want per-edit attribution, one-click revert, Markdown export, and EU hosting

Context Cloud stores memory for your agents. Hjarni keeps a brain your whole team can read.

Common questions

Common questions

What is Context Cloud?

An MCP memory server for engineering teams. It stores knowledge as typed chunks (decisions, findings, conventions, state) in shared workspaces with role-based access control, hybrid retrieval, automatic deduplication, and a web dashboard to curate what the team's AI knows. It works with Claude, Cursor, Codex, Windsurf, and ChatGPT, and is free today. It is a memory store for agents, not a notes app.

Is Context Cloud the only MCP memory server with shared team workspaces?

No. Hjarni teams ship shared workspaces over MCP too: shared folders of Markdown notes with per-folder roles, per-edit attribution naming the person or the specific assistant, and one hosted MCP server that Claude, ChatGPT, Cursor, and other clients connect to. Context Cloud's claim describes the typed-chunk-store category; shared team memory over MCP itself is a choice between shapes, not a single vendor.

How is Hjarni different from Context Cloud?

What memory is, and who reads it. Context Cloud stores typed chunks built for agent recall inside coding tools, browsed through a dashboard. Hjarni stores Markdown documents in folders, so the memory your agents read is also documentation your people read and write directly, in a web app and on iOS and Android, with a full revision history and one-click revert per note.

When should a team pick Context Cloud over Hjarni?

When the memory will be consumed mostly by agents in coding tools and you want typed entries, hybrid recall, and automatic deduplication of stale context. Teams standardized on Claude, Cursor, Codex, and Windsurf who treat memory as infrastructure rather than documentation are its target, and it is free today. Check its export options before committing a team's knowledge to any store.

When is Hjarni the better fit for team memory?

When people need to read and edit the memory too, when part of the team lives in ChatGPT or Claude.ai rather than coding tools, and when you want a visible trail: every edit versioned and attributed to a person or a named assistant, revertable in one click, with the whole knowledge base exportable as plain Markdown. Sharing is asynchronous, like a wiki, which suits decisions and runbooks.

Can my AI's edits to shared team notes be reviewed and undone?

Yes. Every write to a Hjarni note becomes a version attributed to the person or the specific assistant that made it. Teammates can read the diff, revert a bad edit in one click, and recover deleted notes from a 30-day Trash. That does not make agent writes infallible, but it makes them visible, named, and reversible, which is what a team needs to trust shared write access.
