About Teaflask
Teaflask is the AI layer for software companies. It lets any SaaS company put an agent inside its product that carries out tasks for its users, with the controls enterprises require. Customers go live in a day, without a rebuild. Calling a model is the easy part of shipping an in-product agent. The hard part is everything around it: streaming, crash recovery, scaling, guardrails, interfaces that match the product, and knowledge that stays current as the code changes. Teaflask handles all of it with no backend changes, and gives product teams visibility into how their users actually use the product.
