01 / Beyond the dashboard
Take away the interface.
The work carries on.
Finn works through tools and connected services. The dashboard is one way to see and manage that work. Follow an example receipt through the accounting underneath.

Double-entry ledgerHuman oversight
Illustrative workflow using fictional data. This explorer does not process documents or change any books.
Documents & transactions
Extract receipt details, classify transactions and connect documents to the accounting work.
Preparation & review
Prepare month-end work and supported filings, surface blockers and give people the work to review.
02 / Grounded intelligence
An answer should have
something behind it.
Finn brings together facts, working knowledge and official guidance. Country and company context help determine what is relevant to the question.
01
Structured facts
The rule, with its source.
Country rule lookups return a rule and its official source. Structured UK tax facts add numerical data by tax year. Finn is instructed to retrieve these before giving rates and thresholds.
02
Working knowledge
How to apply it.
Skills and wiki knowledge explain accounting workflows. Finn’s Casebook adds practice options and their reasoning after the underlying rule is established.
03
Official guidance
Back to the authority.
Source links let people check the underlying guidance. For supported UK topics, Finn can also retrieve GOV.UK guidance text. The available knowledge varies by country and topic.
Finn is instructed to retrieve facts, cite sources and say when the available knowledge cannot establish an answer. These controls reduce risk; they do not guarantee error-free answers.
03 / Business memory
Your business has context.
Finn can remember it.
How the company works. Decisions you have made. Conversations worth returning to. Company memory gives Finn context that can carry into the next piece of work.
Company knowledgeBusiness details and working preferences in company memory.
Conversation recallEarlier discussions can be retrieved when you need them.
Patterns that inform the next matchSupplier history and saved rules help with recurring work. Changed details still need checking.
Context across conversations
You
We track the studio separately from our client project costs.
f. Finn
I can save that in your company memory so we can refer to it as we work through your books.
Example memory
Studio costs tracked separately from client projects.
Illustrative conversation. Company memory provides context; it does not replace transaction evidence.
04 / Designed for responsibility
The ability to act.
The boundaries to act within.
Accounting needs traceable figures and clear responsibility. Finn combines instructions with tool controls and review workflows.
Retrieve before answering
Financial figures should come from tools. Tax rules should come from the relevant fact sources, with references people can check.
Confirm sensitive actions
Designated tools require confirmation. Access and available actions depend on the user, company and workflow.
Make exceptions visible
Reconciliation and preparation workflows surface items that need attention, so people can apply their judgement.
A person reviews and signs
Finn does the production work. A person reviews and signs every filing. Responsibility stays explicit.
05 / The person you work with
Deep infrastructure.
A straightforward conversation.
Finn’s voice is part of the design: the useful figure first, the explanation where it helps, and a question when something is missing.
Business context, accounting tools and a practical personality, brought together in the same conversation.
