Feature Comparison
Kapitol.ai
Comprehensive Politician Monitoring
Kapitol.ai's system continuously surveils all 535 members of the U.S. Congress, including both the House of Representatives and the Senate. It automatically detects and pulls every new financial disclosure filing the instant it becomes publicly available. This 24/7 surveillance ensures no trade, regardless of how obscure the politician or filing database, slips through the cracks, providing users with complete coverage of all congressional trading activity.
Proprietary Signal Scoring System
Not every congressional trade carries meaningful insider insight. Kapitol.ai analyzes each transaction through a multi-factor scoring model that evaluates committee jurisdiction, trade size, timing relative to legislative events, and sector relevance. Trades are then assigned a clear signal strength: Low, Medium, High, or Critical. This systematic filtering ensures users focus only on the most consequential moves with the highest probability of being based on non-public information.
Plain-English Analysis & Context
Raw trading data is confusing. For every high-signal trade, Kapitol.ai provides detailed, easy-to-understand analysis that explains why the trade matters. This includes insight into the politician's committee roles, potential legislative impacts on the traded company, and the historical performance pattern of similar trades. This context transforms a simple buy/sell alert into an intelligible investment thesis.
Real-Time Alerts & Live Feed
Users do not need to manually search for data. When a high-scoring trade is published, Kapitol.ai sends an immediate email alert directly to the user's inbox. Furthermore, the platform maintains a live preview feed of recent congressional trades, allowing members to see the latest activity at a glance and ensuring they can act on information before the broader market reacts.

Use Cases
Kapitol.ai
Retail Investor Edge Seeking
Individual retail investors can use Kapitol.ai to level the playing field against institutional money. By following the high-conviction, scored trades of congressional insiders who consistently outperform the market, retail traders can inform their own portfolio decisions, using the platform's analysis to validate potential investments and identify emerging sector trends before they become mainstream news.
Trading Strategy Validation
Active traders and day traders can incorporate Kapitol.ai signals as a powerful confirmation tool within their existing technical or fundamental analysis frameworks. A "Critical" signal buy from a relevant committee chair can provide strong fundamental conviction to enter a position, adding a unique layer of politically-informed insight that is absent from traditional market data feeds.
Political Risk Assessment
Investors with large holdings in regulated industries like healthcare, defense, energy, or technology can use the platform to monitor the trading activity of key committee members overseeing those sectors. Unusual buying or selling patterns can serve as an early warning system for upcoming legislative changes, regulatory shifts, or government contracts that may affect specific companies and stock prices.
Market Research & Trend Spotting
Financial analysts, journalists, and researchers can utilize Kapitol.ai to identify macro trends. Aggregated data on which sectors politicians are collectively buying or selling can reveal where legislative focus and government spending might be directed next, providing a forward-looking indicator for broader market and economic analysis.
Pure Tax Investigations
Facing a Serious HMRC Fraud Investigation (COP9)
When an individual or business receives a Code of Practice 9 (COP9) letter from HMRC's Fraud Investigation Service, it indicates a suspected serious tax fraud. Pure Tax Investigations provides critical expert guidance through this daunting process, managing the contractual disclosure facility (CDF) process, preparing a robust disclosure report, and negotiating to secure the best possible civil settlement and avoid criminal prosecution.
Managing a Complex HMRC Enquiry into a Large Business
Large corporates undergoing intensive, cross-tax enquiries benefit from the firm's structured approach. Pure Tax Investigations acts as a strategic buffer, analysing HMRC's information requests, coordinating with the client's accountants, and deploying technical expertise to challenge HMRC's positions and achieve a commercial resolution that minimises disruption and financial impact.
Making a Voluntary Tax Disclosure
For clients with undisclosed tax liabilities related to offshore assets, rental property income, or crypto gains, the firm facilitates voluntary disclosures through HMRC's campaigns like the Worldwide Disclosure Facility (WDF) or Let Property Campaign (LPC). They ensure the disclosure is complete, accurate, and presented optimally to mitigate penalties and interest.
Responding to an HMRC Compliance Check or Information Notice
Even routine HMRC compliance checks can be burdensome. Pure Tax Investigations steps in to handle all communications, ensuring client responses to information notices (Schedule 36) are legally compliant and strategically sound, preventing a simple check from escalating into a wider, more invasive investigation.
Overview
About Kapitol.ai
Kapitol.ai is a specialized financial intelligence platform that transforms opaque congressional stock trading data into clear, actionable investment signals. The product addresses a critical market inefficiency: while the 2012 STOCK Act legally requires all 535 members of Congress to publicly disclose their stock trades, these filings are buried in complex government databases, are notoriously difficult to interpret, and are often delayed. Kapitol.ai solves this by automatically monitoring every politician, collecting each filing the moment it is published, and applying a proprietary scoring algorithm to filter out the noise. Each trade is scored as Low, Medium, High, or Critical based on factors like the politician's committee jurisdiction, the trade's position size, and political timing. The platform then delivers only the highest-signal trades to users with plain-English analysis explaining the context and potential market impact. Designed for retail investors, traders, and financial enthusiasts, Kapitol.ai's core value proposition is democratizing access to the "smart money" insights that have historically given Congressional insiders a documented market advantage, all starting with a free account.

Frequently Asked Questions
Kapitol.ai FAQ
Is it legal to trade based on congressional filings?
Yes, it is completely legal. The trades made by members of Congress are a matter of public record due to the STOCK Act. Kapitol.ai simply aggregates, analyzes, and presents this legally disclosed public information in an accessible format. Users are trading on publicly available data, just like any other market research.
How accurate or profitable are the signals?
Based on Kapitol.ai's tracked record of 157+ curated trades, their scored alerts have achieved a 68% win rate with an average return of +19% after three months. The system is designed to highlight the highest-probability trades, particularly "Critical" signals from committee chairs, which historically represent the strongest insider conviction. However, past performance does not guarantee future results.
What is the delay between the trade and the alert?
By law, Congress members have up to 45 days to disclose their trades. Therefore, there is an inherent delay between when the politician executes the trade and when the filing becomes public. Kapitol.ai's technology eliminates any further delay by alerting you the instant the filing is published online, ensuring you get the data as fast as possible.
What does the free account include?
The free account provides access to a live preview feed of recent congressional trades and basic platform features. It allows users to see the system in action and understand the type of intelligence provided. To receive real-time email alerts for all high-signal trades, along with full context and deep-dive analysis, users need to upgrade to a premium membership.
Pure Tax Investigations FAQ
What makes Pure Tax Investigations different from my accountant?
While accountants handle compliance and routine tax filings, Pure Tax Investigations specialises exclusively in contentious tax matters and HMRC investigations. Their team includes ex-HMRC inspectors with direct experience conducting enquiries, giving them unique tactical and procedural insight to defend clients aggressively, which most general practice firms cannot offer.
What should I do if I receive a Code of Practice 9 (COP9) letter from HMRC?
A COP9 letter is extremely serious and requires immediate, expert attention. You should contact a specialist firm like Pure Tax Investigations immediately and before responding to HMRC. They will advise you on your options, typically involving entering the Contractual Disclosure Facility (CDF) to make a full disclosure and seek a civil settlement, which they will manage on your behalf.
Can you help with disclosures for offshore income or gains?
Yes, Pure Tax Investigations has extensive experience managing disclosures through HMRC's Worldwide Disclosure Facility (WDF) and other offshore campaigns. They ensure all historical income, gains, and related tax liabilities are correctly calculated and disclosed in a manner designed to secure the lowest possible penalties under the relevant legislation.
How do you charge for your tax investigation services?
Given the unique nature of each investigation, Pure Tax Investigations typically operates on a fixed-fee or agreed project-fee basis, tailored to the specific scope and complexity of the case. This provides clients with cost certainty from the outset. An initial consultation is offered to discuss the case details and provide a clear fee proposal.

Others might look for paid platforms with dedicated analyst support or different alert mechanisms that better fit their workflow. When evaluating alternatives, consider the core data source's reliability and timeliness. Look for transparent scoring methodology to gauge trade significance. The platform's usability and the clarity of its analysis are crucial, as raw data without context is of little value.
