Saturn
Saturn sells AI to UK financial advice firms. It turns meetings, documents and scattered records into one client record, drafts the letters advisers must write and checks files for compliance.
Two way integrations connect it to back office, cashflow, portfolio and advice platforms. Workflow tools draft suitability letters and annual reviews, and the Guardian suite automates file checks and meeting observations. CoPlanner brings Saturn into Microsoft Word and the Chrome and Edge browsers.
Saturn says more than 500 advice firms and 3,000 advisers use it, and names Hoxton Wealth, Paradigm Norton and Cooper Parry as clients. It states that client data never trains its models. Saturn Fintech Ltd is based in London.

Turning meetings and documents into structured client data, drafting suitability letters and automating file checks are all model work. Without them, a set of integrations would remain with nothing to carry.
Tools are framed as augmenting advisers, with drafted suitability letters and annual reviews returned to the firm and the Guardian compliance suite running file checks and meeting observations. An approval step required before a drafted document reaches a client is not described.
Accuracy, rework rate and evaluation method are unpublished for drafted letters, data capture and automated file checks. How often advisers materially amend a draft would be the telling figure.
Hoxton Wealth's Jonathon Jay says advisers saved 30 to 45 minutes of note writing per meeting, five to seven hours a week, and Matt Fowler of Paradigm Norton reports about a 50 percent efficiency gain in meetings. More than 500 advice firms and 3,000 advisers are stated as users, and the named figures are the clients' own estimates.
Client data never trains the models, a categorical line, and firms can reach all of their data and set internal permissions.
The privacy policy reaches the service, naming the firm as processor for advice firms on the platform and its add ins, with retention periods for prospect and client contact data. Client record retention and a subprocessor list are unpublished.
External experts audit compliance, privacy and security practices, and a trust center on Oneleet is linked, but no certification or attestation is named on the site.
Compliance automation and visibility of regulatory adherence are described, and a September 2026 report argues for guardrails on AI in advice, but no regulator, rule or regime is named as the platform's basis. Consumer Duty and the conduct rules behind a suitability letter are not mentioned.
Drafted suitability documentation shapes what a client is told to do with their money, and testing of drafting or file checks across client circumstances is not published. The firm's own report found general AI models wrong on 57 percent of 121 financial advice questions, which makes the absence of testing on its own models conspicuous.
Advisers stay the regulated party for the advice a client receives. No guarantee, indemnity or correction route covers a defect traced to the platform.
Models behind drafting, transcription and file checks come from no named provider, and hosting is unstated. Processors appear in the privacy policy only by category: hosting, analytics and communication.
Two way integrations with back office, cashflow and portfolio platforms build a single client record, and the firm ships its own CoPlanner add in for Word and extensions for Chrome and Edge. Its back office and platform partners are not named.
Data is stored in each firm's local residency, configurable to its needs, and encrypted in transit and at rest. Neither a hosting provider nor a region list is published.
Firms are routed to a discovery call, and the bundle of data capture, workflow and compliance tools carries no published price. Charge per adviser, per firm or per module would land very differently on small practices and national firms.
UK financial advice firms of every shape are the market, from independent practices to national and accountancy led firms, with a customers page and solutions across data capture, workflow and compliance. One firm type in one market is a deliberate choice, covered in depth.
