Our story
AI Tax Assistant for CPAs
Feather (askfeather.ai) is an AI Tax Assistant for CPAs, EAs, and tax attorneys: Research, Analyze, Apply. We started Feather after watching practitioners choose between hours in a research platform and pasting client data into a chatbot that invents citations. Tax research should take minutes, not hours - and every answer should be defensible. That's what we built Feather to do - from the first question through to the memo you hand a client or partner.
