Pricing
Kantaja is an AI spreadsheet editor in the browser: edit workbooks, import and export .xlsx files, and use AI to write formulas, fill cells with =AI(), and make changes through an assistant. Every plan includes the full editor; paid plans raise the daily AI usage allowance, measured in credits.
A credit is 5¢ of AI model usage; every call spends by what it actually costs. Pinned =AI() results are free. Yearly is charged once a year with two months free.

Organizations share workbooks with every member. AI usage is covered by the subscription and metered in credits, with optional admin-set caps per organization and per member; there are no separate usage charges. Seats follow the member count automatically as people join and leave. Create an organization from the Kantaja menu in the editor and subscribe in the Organizations section.
