Introducing Feather: The Professional-Grade AI Copilot for Technical Tax Reasoning
The modern tax landscape is not just becoming more complex; it is expanding at an exponential rate. For CPAs, in-house tax teams, and tax attorneys, the challenge today isn't just finding information—it's synthesizing thousands of pages of changing regulations, revenue rulings, and multi-state codes into accurate, defensible strategies.
The industry has long awaited a tool that moves beyond simple keyword search or generic automation. Today, we are proud to introduce Feather, the professional-class AI tax assistant built to bring audit-ready precision to your daily workflow.
Beyond Search: True Technical Reasoning
We built Feather because we believe the future of tax work isn't about replacing the expert; it's about empowering them with a tool that thinks like a practitioner.
Unlike general-purpose AI models that can provide vague or outdated summaries, Feather is engineered for technical tax reasoning. It doesn't just read the tax code; it understands the hierarchy of authority—from IRC Title 26, the OBBB Act and Treasury Regulations to IRS guidance and specific court cases, while also referring to expert practitioner commentary.
Why Feather Changes the Game for CPAs
In an era where "doing more with less" is the norm, Feather offers a distinct competitive advantage for firms and finance departments:
1. Accuracy First, Speed Second (But You Get Both)
The fear of AI in tax is inaccuracy. We solved for this by building Authoritative Citations into the core of our platform. Every insight Feather generates is backed by verified references to the tax code. You can click through to the source material immediately, allowing you to verify the logic and move forward with confidence.
2. Multi-State Mastery
Navigating the web of state-specific regulations is often the biggest time-sink for firms. Feather launches with deep support for the Federal Tax Code alongside major state jurisdictions including California, New York, Texas, Florida, and Delaware. Whether you are dealing with a complex nexus issue in New York or franchise tax in Texas, Feather provides localized, relevant answers.
A common scenario: You can instantly contrast California’s mandatory combined reporting rules with Florida’s separate entity filing requirements without leaving the chat interface.
3. Context-Aware Intelligence
Feather goes beyond the prompt. Our Context-Aware Intelligence proactively identifies related risks, exceptions, and filing requirements that might not have been in your original query.
For example, when assessing passive losses, Feather flags material participation tests that disallow deductions despite involvement. Similarly, for firms reviewing IRC 199A QBI deductions, Feather surfaces SSTB phase-outs that might silently eliminate the deduction. It’s the difference between a tool that answers a question and a partner that watches your back.
4. Chat with your files
Tax work is buried in documents. Feather allows you to upload complex tax filings, notices, and letters to instantly extract insights and summarize key data points. This turns hours of manual review into minutes of strategic analysis.
Security You Can Trust
We understand that data confidentiality is critical, whether you are safeguarding client records at a firm or managing sensitive financials within an in-house tax function. That is why Feather is built on an enterprise-grade security infrastructure. We are SOC 2 compliant, and we strictly adhere to a policy where your data is never used to train our public models. Your organization's privacy is absolute.
