Fiscal.ai (formerly FinChat.io) vs Flyfin

Query company financials through a browser terminal, developer API, or MCP connectors that plug into Claude and ChatGPT. Fiscal.ai grew out of FinChat, the conversational stock-data tool launched in 2023, and now packages fundamentals, ratios, and market data for investors who want one workspace instead of scattered screeners. Visiting finchat.io redirects to fiscal.ai, where the current product lineup is published.

The shift from FinChat to Fiscal.ai reflects a broader scope than a chat box. Terminal is the all-in-one research interface, the Data Feed API serves fintech platforms and institutions, and MCP Connectors expose the same datasets inside AI assistants through OAuth or API keys. That stack competes with patchwork setups of separate screeners, spreadsheets, and custom API glue rather than single-feature chatbots.

Self-directed investors, equity researchers, and developers building investing apps are the core audience. Fiscal.ai reports over 350,000 registered users and raised a $10 million Series A in June 2025. Terminal and MCP plans include a 7-day free trial on signup; API access is positioned for platform integrations.

Flyfin helps U.S. freelancers, contractors, and small business owners hunt tax deductions with AI while a CPA files the return. You connect expense accounts, Flyfin scans transactions against 200-plus deduction categories, and human CPAs review and e-file federal and state taxes when you pick a paid plan. The homepage cites 250,000-plus users, a 4.8 out of 5 rating, and average tax savings around $3,700.

Compared with DIY tax software, Flyfin pairs automated deduction tracking with unlimited CPA chat and optional Zoom calls on higher tiers. The Standard plan covers sole proprietors and single-member LLCs, while Premium adds S-Corp, K-1, and partnership filings plus a designated CPA. Flyfin also sells a separate workflow for CPA firms that want to automate client filings, so it is not just a consumer app with a chatbot bolted on.

Flyfin fits 1099 workers, W-2 employees with side income, and owners juggling quarterly estimates who hate spreadsheet math. Features include swipe-to-accept deductions, a quarterly tax calculator, audit insurance on filing plans, and member perks from partner brands. The company operates in the personal finance and tax prep space with headquarters in San Jose, California, and $8 million in venture funding since its 2020 founding.
