The proof

This site was written by Knave.
So was the email that brought you here.

We run Knave on four of our own businesses before any external customer. Bloodhound. Moss & Tale. Fondness. Amanu. Four verticals. Four voices. Sixty days. The fundraise data is from our portfolio, not a pitch.

How it works

One brand profile.
Every channel.

01

Knave reads your site.

Crawls your homepage, about, services. Shows you what it learned. You correct what is wrong.

Site + PDF + Google Drive ingestion. text-embedding-3-large + pgvector. Three minutes from URL to brand profile review.

02

It writes everything.

Blog. Social. Email. Ad creative. Landing pages. In your voice. On your schedule.

Per-vertical templates. Quality judge gate. Voice match scored 0-100 before anything reaches your queue.

03

You approve. It learns.

Every approval tightens the voice judge. After 20, autopilot per surface unlocks.

Approval queue, edit-and-approve, bulk-approve, reject-with-reason. Voice judge calibrates against your edits.

04

Insights find you.

Rank opportunities, performance anomalies, competitor moves. Dashboard, email, iOS push.

Eight insight categories. Hard cap of 3 push notifications a day. Quiet hours. Empty-state mornings stay empty.

The voice judge

Generic AI writing
never reaches your queue.

Every output is scored on voice match against your brand profile before you see it. Below 70 surfaces with a low-confidence badge. Below 50 regenerates. 85 or above is required for autopilot to send.

The judge calibrates against every edit you make. By approval twenty it sounds like you wrote it.

Common questions

Things people ask.

Will it sound like AI wrote it?+

No. We crawl your site, build a brand profile, and run a voice judge on every output. By your 20th approval, the judge has enough data to keep new drafts in voice. Generic AI writing never reaches your queue. Drafts below voice 50 regenerate before you see them.

Do I need Klaviyo or Mailchimp first?+

No. Knave includes a CRM-lite by default with newsletter signup forms, contact storage, lifecycle automations, and email sending via Resend on your verified domain. Connect Klaviyo or Mailchimp later and your contacts dual-write.

What about regulated industries?+

If you sign up as financial services, legal, medical, or healthcare, we permanently disable autopilot. AI drafts everything; you approve everything. Vertical-specific never-answer rules in the chat widget. We don't hand out advice on your behalf.

What happens at the end of the trial?+

Your account goes read-only on day 14 if you haven't picked a plan. Data stays for 30 days, then we email you twice and delete it. No surprise charges, no card on file, no chasing.

How does the agency reseller tier work?+

£699 a month for 5 client installations, £1,299 for 20. Each client gets their own brand profile, voice judge, and approval queue under your white-label. You set the customer-facing price. We don't talk to your clients.

Can I bring my own LLM keys?+

Yes, at Plus tier and above. Drop in your Anthropic and OpenAI keys, your tier price drops by £200, and your usage runs on your bill instead of ours.
