Myelin: Faster signals, fewer tokens.
Myelin is the stateful infrastructure for humans and agents: persistent context, shared sessions, any agent. No lock-in, no starting over.
Myelin in four primitives
A session to work in, the routing underneath, the cowork between humans and agents, and the spend guardrails on top.
How it works
Use cases
Multi-day migrations
Pick up a week-long refactor exactly where you left off. Context outlives the session.
Cross-agent workflows
Design with one agent, execute with another. The full session state travels between them.
Shift-change handoffs
Pass a live debugging session to the next engineer with every hypothesis and dead end intact.
Batch run recovery
An overnight job fails partway through. Resume from the last checkpoint instead of rerunning everything you already paid for.
Side-by-side fix trials
When two fixes look equally plausible, fork the session and try both. The context the agent already built carries into each branch.
Your data never stays with us
Myelin sits between your apps and the AI provider (Claude, Codex, anything you wire in). Every request is relayed and forgotten. Your keys, your auth, and your audit log live in your cloud.
Your keys, never extracted
Whatever AI provider you use (Claude, Codex, anything you wire in), your keys live in your account. Granica never has them.
Your tenant, never shared
Single-tenant by architecture. No multi-tenant compute, no shared storage, no shared anything between you and another customer.
Your agent, never above you
An agent acts as the human who started it. Same auth scope, same repo permissions, same data visibility. No escalation paths.
Your audit, never in our bucket
Every prompt, every model swap, every action lands in your cloud's audit bucket, hash-chained for tamper detection.
Supported models
Bring your own API key. No new accounts.
Enterprise control,
without infrastructure sprawl.
Spend caps, audit trails, SSO, and a deployment posture that matches your security org. Myelin never holds a copy of your data.
- 01
Private by default
Each session is yours alone, visible to teammates only when you grant them in.
- 02
Enterprise access control
SSO, RBAC, key scoping, per-session permissions. Your security team's controls preserved.
- 03
Compliance ready
SOC 2 in flight, GDPR-ready, immutable audit trail held in your account.
- 04
Single-tenant in your VPC
Helm-deployed into AWS, GCP, or Azure. Your data, your boundary, never shared.
FAQs
How do you handle my code and prompts?
Myelin deploys into your cloud account. Code, prompts, and shared memory never leave the boundary. We don't train on any of it. Cross-customer learning is opt-in only, and only as anonymized structural patterns.
Does data leave my cloud?
No, not by default. You opt in if you want anonymized usage patterns shared back for a usage discount. Every byte that leaves your perimeter has an audit log entry.
How do I keep spend under control?
Set token and dollar budgets per session, per team, or per agent. Myelin throttles before the cap, alerts at user-defined thresholds, and cuts off cleanly when the budget is exhausted. Spend telemetry streams to your existing observability stack.
How does context persist when I switch models or tools?
Myelin holds session context on a layered memory plane that sits underneath the routing layer. When Myelin hot-swaps to a different model mid-task, the new model picks up the same context. No reset, no re-derivation.
Can multiple developers share a session?
Yes. Pair on a Beam session, fork it, or hand it off. The next teammate resumes mid-task; the session already knows the codebase, the constraints, and the recent decisions.
What's the pricing?
$25 per user per month for teams. Enterprise plans for larger orgs with custom budgets, SSO, and dedicated support.
How fast is onboarding?
About five minutes. Log in with your Claude or Codex account, subscription or API, and Myelin starts optimizing from minute one.
Which clouds do you deploy in?
AWS, GCP, and Azure. Myelin runs in your cloud account; the control plane can be Granica-hosted, hybrid, or fully in your cloud depending on your security posture.
What happens if I cancel?
Your sessions, memory, and configuration stay in your cloud account. We turn off the orchestration; your existing Claude or Codex accounts keep working as they did before. No lock-in.
