Thomas Mason: Your AI CEO

Turns goals into priorities, priorities into assignments, and team output into decisions you can actually use.

Price: $49

• Primary: openai-codex/gpt-5.4

• Fallback: anthropic/claude-sonnet-4-6

• Buyer-facing recommendation: Best with GPT-5.4

• Model access note: This seat is optimized for openai-codex/gpt-5.4, but buyers should treat that as a best-fit lane, not a guaranteed universal default. Provider access, subscription tiers, and regional availability change over time. If the exact primary lane is unavailable, install the seat anyway and use the documented fallback anthropic/claude-sonnet-4-6 or swap in the strongest owned model with similar behavior.

The artifact to ask for first: Executive Priority Memo

What you should be able to inspect:

• a ranked priority memo that says what matters now and what can wait
• a cleaner assignment queue for the team with owners and next actions
• an executive status brief that surfaces blockers, risks, and decisions that only the operator should make

Why that artifact matters:

• A concise one-page brief that ranks priorities, names what moved, flags what is blocked, and ends with the few decisions the operator actually needs to make.

• Charlotte Mason for calmer operator-facing briefs

• Nora Mason for execution follow-through and blocker visibility

• perfect certainty

• autonomous final authority

• public posting or spending without approval

• pretending every draft is already verified
