Unblocked indexes the knowledge your team already produced — code, PRs, tickets, Slack threads, docs — and answers questions with citations. Contextium is where your team writes down what it has decided, and serves that to every AI tool. Those are different jobs, and plenty of teams want both.

Contextium holds what your team decided, written down on purpose. Someone authors it, someone reviews it, and every change is versioned — so when an agent reads your conventions you know exactly what it read and who last changed it.
Unblocked reads the knowledge you already have and reasons across it, resolving conflicts between sources and ranking what is relevant. Nobody has to write anything new — which is genuinely the fastest way to make scattered knowledge answerable.
Some context is not a fact to look up, it is an instruction to obey: this is our error-handling convention, this dependency is off-limits, this service is owned by that team. Contextium is built to hold that kind of standing decision and serve it to every agent that connects.
Unblocked is a retrieval layer, and a good one — but a search over three years of discussion will surface the argument as readily as the conclusion. It treats your main branch as the source of truth for code; for decisions, the source of truth is whatever thread it finds.
Contextium is deliberately narrower. Your context lives in libraries you write and maintain, and files can be imported — but it does not stand in front of your whole toolchain and index it. If your problem is “our knowledge is spread across a dozen systems”, Contextium alone will not solve it.
Unblocked connects 27 engineering tools — repositories, CI systems, docs platforms, issue trackers, chat, observability and a data warehouse — and reasons across all of them at once. This is the strongest single reason to choose it, and we are not going to argue with it.
Contextium is not SOC 2 certified and we will not imply otherwise. Our SOC 2 Type I programme is underway: policies are written and technical controls are implemented and evidenced, with an AICPA-licensed audit the remaining step. Data is encrypted, authentication runs through Microsoft Entra ID, access is role-based and changes are audit-logged.
Unblocked is SOC 2 Type II certified and CASA Tier II verified, states that it never trains on customer data, enforces your existing source-tool permissions, and offers on-premises or own-cloud deployment on its Enterprise tier. If a security review is gating your purchase this month, that is a real advantage.
Individuals are free — not a trial, and MCP access is included from the free plan. Teams pay one flat per-seat price with no usage meters, so briefing your AI tools does not carry a separate bill.
Unblocked starts at $19/user/month annually ($23 monthly) for its Code Review tier. The MCP integration that briefs Claude, Cursor and Copilot sits on the Platform tier at $29/user/month annually ($35 monthly). There is a 21-day trial with no card required, and no permanent free plan.
The reasons to choose Contextium hold no matter what you're switching from.
Works with any MCP-compatible AI tool — Claude, Cursor, Copilot, Gemini and more. Your context is never trapped in one editor or model.
Relevance-based loading serves the context each task needs — not your whole knowledge base on every request.
Every change is versioned with an event log, so teams can see who changed what and roll back.
Free for individuals, one simple per-seat price for teams. No usage meters or surprise overage bills.
Different jobs — many teams run both
It stays the fastest way to answer “why is this code like this?” across PRs, tickets and threads you are never going to rewrite. Nothing to migrate away from.
Conventions, architecture, ownership and the rules agents must follow go into libraries your team authors, reviews and versions — one current answer instead of a search result.
Add the Contextium remote MCP URL (or run npx @contextium/mcp-server@latest setup) in Claude, Cursor and Copilot. Every teammate’s tools arrive briefed on the same standards.
Sometimes, and it depends on the job. If you need to make years of scattered knowledge searchable across Slack, Jira, Confluence and your repositories, Unblocked is built for that and Contextium is not. If you need one authored, versioned source of truth that tells every AI tool what your team has decided, that is Contextium. Teams comparing the two usually find they want both.
No. Unblocked connects 27 engineering tools and indexes them continuously; Contextium holds context you author and maintain, with imports for existing documents. If a live index across your whole stack is the requirement, Unblocked is the stronger fit and we would say so.
Yes, and it is a sensible pairing. They connect to your AI tools independently over MCP. Unblocked answers questions about what happened; Contextium carries the standards your agents should follow next time. Neither one needs to be removed for the other to work.
Contextium, at the entry point: individuals are free permanently and MCP access is included on every plan. Unblocked has no free plan — a 21-day trial, then $19/user/month annually for Code Review, and $29/user/month annually for the Platform tier that includes MCP. Compare like for like: Unblocked’s code review and CI triage features have no Contextium equivalent, so the cheaper product is also doing less.
Not yet, and we will not claim otherwise. Unblocked is SOC 2 Type II certified and CASA Tier II verified. Our SOC 2 Type I programme is underway — policies written, technical controls implemented and evidenced, with an AICPA-licensed audit the remaining step. Full detail is on our security page, and enterprise buyers can contact us for current documentation.
Give every AI tool on your team one authored, versioned source of truth. Free for individuals.
