Assumptions

30-day month; the same daily load count applies to each selected skill.
Model prices use recorded input prices per 1 million tokens. Output prices are not listed and output tokens are excluded.
Skill costs cover SKILL.md input tokens only, using recorded per-1,000-load estimates; bundled files and execution are excluded.
Token and skill inputs are separate workloads; avoid entering skill-loading tokens twice.
Only structured numeric MCP rates count; text notes are not parsed. Missing per-call prices are excluded.
Seats multiply only recorded per-seat plans; bundled and flat plans remain flat. Annual plans use their recorded monthly equivalent.
Currencies are not converted; totals remain separate. Taxes, hosting, BYOK inference, unlisted prices and other unrecorded costs are excluded.
Zero inputs are your scenario defaults, not recorded usage. Subtotals are not a quote or a usage prediction.

FAQ

What does My AI Stack do?

My AI Stack lets you select AI tools, plans, seats, open-source repositories and skills, calculate listed monthly costs, and see recorded price changes and possible swaps.

Is it free?

Yes. My AI Stack is free to use, with no login required.

How is the cost calculated?

Costs use listed plan prices × seats for per-seat plans; flat-price plans remain flat. Recorded token, per-call and skill prices are included only when listed. Skill loads use a 30-day month. There is no currency conversion, and unlisted prices are excluded.
