AIVM Brain vs Glean
A mature enterprise work-AI suite, vs a governance-and-proof layer you can start free.
Glean is a mature enterprise search and work-AI suite with 100+ connectors, sold enterprise-first. AIVM Brain is a governance-and-proof layer you can start free and self-serve, with a content-blind, tamper-evident audit, an optional on-chain proof, and bring-your-own-model key. Both are permission-aware. They differ on how you buy, what you can prove, and where your data and model live.

Why teams compare them
Glean is a strong, well-built product. Teams comparing it to Brain are usually weighing two different things: a complete enterprise search and assistant suite bought through sales, versus a lighter governance layer they can turn on today and prove to their auditors. The right answer depends on whether you need breadth and a full suite, or governance, proof and ownership.
Both respect permissions, so what is the real difference
Glean checks each user's permissions in real time before it answers, and so does Brain. The difference is not whether access is governed, it is what you can prove afterwards and how you buy. Brain's log is content-blind and tamper-evident, and it can anchor a cryptographic record on-chain of exactly what the model answered over, which is the kind of proof a board or auditor asks for. Brain also lets you bring your own model key so usage and data stay yours.
Buy it today, or run a procurement
Glean is sold enterprise-first, with custom quotes and roughly a 100-seat minimum. That fits large organizations standardizing on a full work-AI suite. Brain is free to start and self-serve, with transparent tiers from individuals to teams to enterprise, so you can prove the value before you sign anything.
Where Glean is the better fit
Glean is a more mature, more complete enterprise search and answers product, with well over 100 connectors and a broad assistant and agent suite. If you are a large enterprise standardizing on one work-AI platform and you want maximum breadth through a sales-led rollout, Glean is excellent. Brain is the better fit when you want governance, provable audit, model and data ownership, and to start now.
Who each is best for
Questions, answered
Is AIVM Brain a Glean alternative?
Yes, for teams that want governance, provable audit and model ownership without a sales-led enterprise contract. Both are permission-aware; Brain is lighter to adopt and emphasizes proof and ownership, while Glean is a broader enterprise search suite.
Is Brain or Glean more secure?
Both check permissions before answering. Brain adds a content-blind, tamper-evident audit and an optional on-chain anchor of what the model answered over, which is a distinct kind of provability. Glean brings mature enterprise security across a broad suite. The better choice depends on whether provable audit and model ownership or suite breadth matters more to you.
How much does each cost?
Brain is free to start with transparent per-seat tiers. Glean is sales-led with custom quotes, typically around $50+ per user per month and roughly a 100-seat minimum.
