Ask Sage vs Stack AI (2026): which should you pick?

Pick Ask Sage if

• Fits if you buy for a government agency or defense contractor
• Works for teams that want to compare several models in one controlled workspace

Look elsewhere if

• Not for you if you want a price, as none is published and cost follows token volume
• Skip it if you are an individual, since it is aimed at defense, federal and commercial enterprise buyers
• Too light on detail: no integrations or free tier are listed on the pages read

Pick Stack AI if

• Fits if you want to build one or two agents and try them free
• Makes sense if you plan to ask for an enterprise deployment later

Look elsewhere if

• Tight if you work in a team, as Free is 1 seat and 2 projects
• Not for you if you want a self-serve paid plan, because none is published
• Watch out: SSO, access control, VPC and on-prem are Enterprise only
• Watch out: the homepage says Asana acquires StackAI, so ownership and plans may change

Ask Sage

• No prices are published; the How to Buy page lists card payment, cloud marketplaces and government contract vehicles.
• Usage is sold as tokens that teams can distribute among members, so cost depends on volume.
• The vendor positions it for defense, federal civilian, defense industrial base and commercial enterprise buyers.

Stack AI

• Only a Free plan and a custom Enterprise plan are listed; there is no published self-serve paid tier.
• The free plan has 1 seat, 2 projects and 500 runs a month.
• SSO, access control, VPC, on-prem and BAA are Enterprise features.
• Its homepage says Asana acquires StackAI, so plans and ownership may change.
