As answered by people managing US GAAP Buddy and React-Ionic.
US GAAP Buddy's answer
Built as the US GAAP counterpart to IFRS Buddy, US GAAP Buddy was created to solve the same problem on the other side of the Atlantic: the ASC codification is notoriously complex to navigate, and general AI tools frequently misattribute or hallucinate paragraph references. The goal was a fast, reliable assistant that any accountant could trust for day-to-day standard lookups.
US GAAP Buddy's answer
US-based accountants, auditors, controllers, and finance professionals who work with ASC standards daily. Also used by international professionals — particularly in Europe and Latin America — who work with US-listed companies or dual-reporting entities.
US GAAP Buddy's answer
US GAAP Buddy is the only AI assistant built exclusively around the ASC codification. Every answer cites the exact subtopic and paragraph (e.g. ASC 450-20-25-2, ASC 842-20-30-1) — never at bare-topic level. Unlike general AI tools, it refuses to answer IFRS questions and redirects them to its sister product, keeping every response strictly within US GAAP scope.
US GAAP Buddy's answer
Enterprise tools like Thomson Reuters Checkpoint or Bloomberg Tax are powerful but expensive and built for large firms. US GAAP Buddy is affordable, instant, and accessible to individual professionals — no contract, no training required. It combines the depth of a codification lookup tool with the conversational clarity of a knowledgeable colleague.
US GAAP Buddy's answer
FastAPI (Python backend), Next.js 14 (frontend), PostgreSQL, ChromaDB for vector search (RAG), and frontier LLMs including Claude and GPT for response generation. Hosted on a dedicated VPS with Cloudflare CDN.
