Colchix vs. nexos.ai

An AI workspace and gateway: teams move their AI use into nexos, which masks what passes through it. Strong where it stands. Under the X-ray, here's where it breaks, and what Colchix brings instead.

Its benches on the Argo

  4. Nothing outside nexos

The benches

nexos.ai's ship, and ours

Governing AI takes a whole crew: the console, the lookout, the guard, the scribe and the judge.

    One console for every AI tool and every team, with the gap still to cover given as a number.

    Turns everyday AI activity into evidence for the EU AI Act, GDPR and ISO/IEC 42001.

  • THEMISThe judge

    Filled.

    Our own model, in Europe: finds and judges in one pass, a confidence for every value, under 100 ms (target).

Head to head

nexos.ai and Colchix, row by row

How values are foundnexos.ai: PII detection, regex and custom termsColchix: THEMIS finds and judges in one pass over the whole textA separate finder caps what can be protected: regex alone found 59 in 100, a finder then a judge 69.
Exact boundariesnexos.ai: Not publishedColchix: Trained and scored on exact spans (target: ≥ 90 in 100 protected)Half a value leaks: mask “Kestrel” in “Project Kestrel” and the project is still named.
Would masking break the request?nexos.ai: Not documentedColchix: Asked for every value, and learned from examplesMask everything and the answer is useless; mask nothing and it leaks.
Confidence per valuenexos.ai: Not publishedColchix: A calibrated probability for every valueA threshold on an uncalibrated score is a guess.
Real values back in the replynexos.ai: Not documentedColchix: Yes, restored while the answer streamsAnna gets a usable answer instead of [REDACTED].
Whole attachmentsnexos.ai: Not publishedColchix: 16k tokens in 0.8 s (target); refuses rather than cutsPeople attach contracts and exports. A silent cut-off is a silent leak.
Speed on every sendnexos.ai: Not publishedColchix: Under 100 ms per message, median (target)It sits in front of the send button. Slow protection gets switched off.
Where the model runsnexos.ai: In the EU (Lithuania)Colchix: Our own weights, in the EU, or in your own cloudResidency, and no new sub-processor for your DPO to object to.
Evidence for auditsnexos.ai: What passes through nexosColchix: ATHENA files every record under the rule it provesThe EU AI Act, GDPR and ISO/IEC 42001 ask for proof, not policies.
Every AI tool, every devicenexos.ai: Only AI use moved into nexosColchix: ARGUS finds them all, personal accounts includedYou can't protect what you can't see.

Anna asks for a reminder about a late invoice, with an email and an IBAN in it.

Dear jane@acme.com, invoice IT60X0542811101000000123456 is now 14 days late…

Colchix vs. nexos.ai FAQs

What people ask when they put Colchix next to nexos.ai.

What's the difference between Colchix and nexos.ai?

nexos.ai is a place to move your AI use to: it masks what passes through its workspace and gateway. Colchix governs AI where people already use it, the browser, desktop apps, coding agents and MCP, finds the tools nobody moved, and gives the real values back in every answer.

Both are European. What does Colchix add?

Reach and the round trip. Colchix doesn't need staff to change tools, ARGUS shows the AI use outside any workspace, and THEMIS, our own model in the EU, judges each value with a confidence you can set rules on.

Can Colchix govern nexos itself?

Yes. ARGUS sees nexos as one more AI tool in use, and TALOS protects what's sent through it, like any other.

nexos.ai's capabilities from its public documentation (nexos.ai), checked on 30 September 2026. THEMIS figures are release targets. Something out of date? Write to hello@colchix.com.
