A working system — running live on this page
The knowledge desk that refuses to guess.
Proofdesk answers your team’s questions from your own contracts, policies, and manuals. Every answer opens the exact passage it came from — and an answer the documents can’t prove is declined, never dressed up.
Built for your business · Integrated into your tools · Owned by you
No subscription, no per-seat pricing — we build it around your documents and systems, hand it over, and it’s yours.
How it works
Ask a question. Get a proven answer — or an honest no.
Five stages, every time. The checking cannot be skipped: if any part of the system has a bad day, the desk declines rather than guesses.
- 1
You ask
In plain language, like messaging a colleague.
- 2
It finds
The passages in your documents that bear on the question — with their exact location.
- 3
It drafts
An answer where every part carries its source.
- 4
A second AI checks
A different company’s AI verifies every part against the documents. It never grades its own homework.
- 5
Proven — or declined
Every part proven: the answer ships with its proof. Anything unproven: the desk declines and shows the closest passages.
And it runs itself
Reads
Documents are split into passages that keep their exact place — that’s why a citation can highlight the exact lines.
Records
Every answer and refusal is stored — what was found, what was checked, what it cost, how long it took.
Examines itself
It re-takes a fixed exam of graded questions; every result is stored and traceable.
Never goes dark
If the pipeline is ever down, recorded real runs play instead — you never meet a dead demo.
All of it is running on this page right now — ask it yourself. Open the desk
Watch a real question
Watch the checking happen.
The pipeline you just read, playing back a recorded question — the passages found, the draft, every part checked, the stamp.
As amended, what monthly service retainer does Meridian now charge Brookfield Clinic?
The passages are found, the draft is written, and a second AI checks every part — you are about to watch it happen.
a real recorded run —
The part no other tool does
When the documents don’t prove it, it says so.
A real declined run, at full ceremony. No guess, no error screen — the closest passages, and the decision left with you.
What monthly gym-membership allowance does Meridian offer its staff?
The passages are found, the draft is written, and a second AI checks every part — you are about to watch it happen.

How we know
Every claim here has receipts.
Nothing on this page is asserted by hand. Three things back it up — a fixed exam of graded questions, the recorded trail behind every answer, and a refusal we caused on purpose.
The graded exam
You don’t have to take our word for it: the desk is run against a fixed set of real graded questions — some answerable, some deliberately not — and every result traces to a stored run.
The paper trail
Every answer and refusal is recorded — what was asked, what was found, what was checked, what it cost, how long it took. Open any answer’s proof pack to see the whole receipt.
The kill switch
We broke a key on purpose to see what happens when the checker can’t run — it refused, rather than answer unchecked. That recorded refusal is in the replay bank, clearly labeled.
Scale, stated honestly
A public example to browse. A million-word project used to test the system.
They are separate on purpose. The public example is open to browse. The larger project uses a made-up company only for scale testing. Neither contains client data.

Recorded knowledge state
- DocumentsReady
- ConnectionsReady
- Across documentsReady
These labels describe saved documents and their connections, not answer quality; every answer still has to prove itself from exact passages. The full 73-question comparison between the usual search and the broader across-document search is still pending, so there is no result or better-answer claim yet.
One document was re-read and connection sets for 3 of 997 documents were recalculated. An independent full check still matched all 2,991 nearest-document links.
What we build for you
Your desk is assembled from these blocks.
Proofdesk isn’t a subscription you sign up for. It’s a system we build for your business from proven blocks — the gold-chipped ones are running on this site right now; the rest we add on request, wired to your documents, your rules, and your tools.

The trust core
why this desk cannot lie to you
The honesty check
No confident wrong answer can reach your team: a second, independent AI checks every part of an answer against your documents before you see it.
Checking strictness tuned to your risk — a clinic is not a sales team.
watch it workProof on every answer
Verify in one click: every answer opens to the exact place in the exact document it came from.
Your documents, your numbering, your language.
watch it workThe honest “I don’t know”
Unproven answers are withheld — you get the closest passages instead of a guess.
The refusal message and the escalation path are written for your team.
watch it workThe graded exam
You don’t have to take our word for it: the desk is graded on a fixed exam of real questions — answered, proven, declined — and every result is stored.
A private scoreboard on your own questions comes with every engagement.

Runs on your own machine
The whole desk — including the AI — on a machine in your building. Nothing leaves.
We size and set up the hardware.
Your choice of AI
It runs on the AI you choose.
When we build your desk, you choose what powers each stage — capable AI we run at no per-answer charge, paid frontier AI, or open AI on hardware you own, where your documents never leave the building. One rule holds in every choice: the checker is always a different company’s AI than the writer. Cost is per answer, never per seat — and you never pay inside this app.

Why not just use the big tools?
Use them if they fit — here is the one thing they don’t do. And they are subscriptions to someone else’s system; this one is built for you, and it’s yours.
| Tool | What it does well | What it won’t do |
|---|---|---|
| Glean | Company-wide search and assistant for large enterprises, with strong citations. | Its own docs say ungrounded answers still reach users — it monitors quality afterward; it never refuses. Sales-led, ~100-seat economics. |
| Guru | A verified company wiki — humans stamp documents as trusted. | Verification is a badge on documents, not a check on answers; its guardrails are off by default and fail open when the checker is down. |
| Onyx | Open-source chat over your company tools; you can self-host it. | Bets everything on good retrieval — no check that the answer is actually proven, and the permission layer is paywalled. |
| Do it yourself | Free open tools can chat with your documents on your hardware. | A raw tool, not a service: no checking layer, no scoreboard, and someone in-house has to build, tune, and maintain it. |
| Proofdesk | Answers proven against your documents, or honestly declined — every run recorded. | It will not show you a guess. That is the point. |
The next step
Get it built for your business — with a free test run first.
One door: tell Danylo about your business, get a funded test run, and we build it for you if it fits.
Everything on this page is the live product — not a mock-up, not a slide.
We build and hand over a version of it for your business: wired into your tools, owned by you.
You get $10 of test usage on our infrastructure first — on our prepared example documents, or on your own. The invite code comes from asking Danylo.
Your documents, and your team’s corrections, make it smarter over time — and it refuses to guess. It becomes your system, not a rented tool.

What the manual way costs
For a 20-person firm, digging answers out of contracts and policies by hand runs to roughly $14,000 a year of interrupted time — before counting the one missed clause that auto-renews a bad rate. A worked example, not a measurement: your numbers replace these.
worked example
For a clinic, the bigger cost is risk: one confidently wrong protocol answer is an unbounded liability. Proven-or-refused — never guessed — is the property that makes AI answers usable in that setting at all. A real buyer with $276,000 of spend history was hiring, from scratch, exactly this checking layer. A worked example, not a measurement.
