Finchley
For agencies who want to sell AI support, not just build it

Every client is asking for an AI assistant. Now you can say yes, and prove it works.

Finchley turns a client’s documents into a support assistant you can test, show them, and put on their site with one line. Then charge for it every month, on your own model keys, with nothing marked up.

14 days free. No card. Bring your own model keys.

Every client is asking for one.

“Can we have a chatbot?” is now on every brief. Saying yes has meant a one-off build each time.

You could build one. You can’t maintain twenty.

A developer can wire up an API in a week. Then prompts drift, documents change, keys expire, and nobody on the account team can fix it.

Nobody can prove it’s right.

The first time anyone finds out the bot says “14 days” instead of “30” is a customer, on the client’s site.

How it works

Three steps. Under five minutes to the first useful answer.

Step 1
Add what it should know

Drop the client’s documents, a folder, or their website. Finchley reads them straight away and keeps websites fresh every day. Scanned menus and photos are read too.

The assistant said 14 days. You expected 30. Check the returns policy source.
Step 2
Prove it before you invoice

Share a readiness page the client can open across a table: the pass rate, what it gets right, and what still needs a source. Behind it, Finchley proposes test questions from the documents and grades every answer.

Step 3
Put it on the site with one line

Paste one script tag. The widget picks up the name, colours and knowledge from Finchley, so there is nothing else to change on the client’s site, ever.

What you get

Everything an agency needs to run assistants for clients, in one quiet place.

Knowledge from anything

PDF, Word, Excel, PowerPoint, CSV, email, images, whole folders, and websites checked daily. Replace a file and the assistant knows straight away.

A readiness page that closes the deal

A shareable page with the pass rate and what still needs sorting, in plain words. Open it in the pitch, send it before launch, and let the client sign off on evidence.

Tools with a sensible default

Connect Shopify, HubSpot or any MCP server. Every action is Off, Allowed, or Ask first. Anything that writes asks the customer before it acts.

Logs that close the loop

Every real conversation, with citations and tool calls. Flag an answer, add a note, and turn it into a test so it can’t slip again.

Your brand, your domain

Your colours on the dashboard and the widget, your own domain for sign-in and client pages, and no “Powered by” on Studio.

Your keys, your margin

Model usage runs on your own Anthropic and OpenAI keys. Finchley never marks up tokens, and each client has a spend limit you set.

The companion mark

It never speaks. It just tells you how things are.

A small mark lives next to each client and inside every widget. It reads while documents come in, thinks while it answers, looks up when a test fails and closes its eyes when everything passes. Agencies can hide it or use the client’s logo instead.

£1,301
a month in margin, ten clients

Studio is £199 a month for unlimited clients. Charge each client £150 a month for a managed assistant and 10 clients is £1,301 a month in margin, before model usage on your own keys. The subscription is flat, so every client after the first is almost all margin.

Model usage runs on your own Anthropic and OpenAI keys and is billed by them at their rates. Finchley never marks up tokens. Prices exclude VAT. The margin example uses a per-client price agencies commonly charge; yours is up to you.

Questions

Things agencies ask before they start.

Why do I bring my own model keys?

So your costs are your costs. You pay Anthropic and OpenAI directly at their rates and set a monthly spend limit per client. Finchley is a flat subscription and never adds a margin to tokens.

What should I charge my clients?

Most agencies charge between £150 and £300 a month per client for a managed assistant, sometimes bundled into a retainer. The Finchley subscription is flat, so beyond the first client or two the rest is margin. Model usage is on your keys and is usually a few pounds a month per client.

Do I need a developer?

No. Documents in, tests, one script tag on the client’s site. A developer is only needed if you want to connect a custom MCP server or write your own tools.

What happens to a client’s documents?

They are read into a private index for that workspace and used only to answer that client’s customers. Nothing is used to train anyone’s models. Remove a workspace and everything is kept for 30 days, then deleted.

What files can it read?

PDF, Word, Excel, PowerPoint, Markdown, CSV, plain text, email exports, images and zips or whole folders. Websites are fetched and checked for changes every day. Scanned PDFs and photos are transcribed.

How do the tests work?

A test is a question and the behaviour you expect, in plain words. Finchley asks the assistant and a second model grades the answer against your expectation, then explains any miss. Finchley proposes tests from the documents; you keep the ones you agree with.

Can my client see it?

Yes. Share a read-only readiness page that updates every time tests run, and invite people at the client to see logs and tests for their workspace only.

Can I cancel?

Any time from the billing page. The assistant keeps answering until the end of the period you have paid for.
