FAQ

What is MasterOS?

A control plane that gives you safe access to multiple AI models, reusable Skills, and (eventually) org knowledge and automation, from a single account. See Overview.

Which model should I use?

Start with the fast tier for most tasks — it's available on every plan. See Switch model tiers for what each tier is for.

Is there a free plan?

Yes — see current pricing and included model tiers on the plans list in the product itself (GET /v1/plans is public, no sign-in required — see API Reference).

Can I use my own OpenAI/Anthropic API key?

Not yet. Bringing your own provider key (BYOK) is planned for a later phase — see Architecture → Components.

Can other people on my team see my files or conversations?

No — in this edition (Personal), files and conversations are private to your own account. Team-shared Knowledge is planned for the Team/Organization editions.

Where do I report a bug or ask something not covered here?

This FAQ is a starting point, not exhaustive — if something's missing, that's a gap in the docs, not necessarily in the product; check Changelog for recent changes first.
