How it works

How does AgentDoor work?

AgentDoor has two sides. A vendor pastes a website URL, approves what the crawler read, and publishes a door that answers buyers' questions from those sources only, citing the sources it used. A buyer describes a need in plain language; their agent interviews the matching doors with the same five questions, asks follow-ups where answers were incomplete, and returns a fit matrix and an approval document.

Vendor side

Opening a door — six steps

Every screen below is the product's own wording. Company names, dates and counts inside them are examples.

Create a free door

STEP 01

Paste a URL, get a drafted door

You paste your company's website URL. We read public pages on that host and draft an agent that answers buyers' questions. No account is needed. Your management link is shown once, right after creation — save it there and then.

  • Public pages on the same host only, up to 5 of them per run (the homepage plus pages like pricing and security).
  • No credentials are sent with those fetches, so nothing behind a login can be read.
  • What you get is a draft. Nobody sees it until you publish.
  • The Free plan is one door and 30 answers a month. No card is needed to create it. On Free, a card must be on file before you accept a meeting, and the success fee is ¥15,000 (incl. tax) per meeting you accept whose date is fixed; the first one is free.

STEP 02

Approve what it read, then publish

The manage screen lists every page we read, unapproved. Only approved sources are used in answers, and an answer cites the sources it used. Anything your site does not show can be added as a Markdown or plain-text document.

  • A document can be up to 20,000 characters, up to 10 per door; an answer reads at most the first 5,000 characters of each source.
  • A door with no approved source cannot be published.
  • Revoke an approval and that source is not used in later answers.

STEP 03

Find the questions it cannot answer first

We ask your own door the five interview questions and the ten buyers most often ask, on your behalf. Each unanswered one comes with the kind of document that would close it and a box to write the answer straight in. What you write is saved as an approved document.

  • 15 questions per check. It costs none of your monthly answers.
  • Pick the register (plain, polite, formal business) and how the door addresses the asker's company.
  • Tone changes wording only. Silence is never rephrased as "not supported".

STEP 04

The public door answers buyers and their agents

A published door shows its approved-source count, when it was last updated, and its security checksheet tally. Visitors ask there and then, and an answer cites the sources it used. Where the sources are silent, the door says so instead of guessing.

  • The security checksheet answers 25 standard items — the ones common to ISO 27001, SOC 2 and the IPA guidelines — from the approved sources only.
  • The same URL returns Markdown to AI agents. Both views are built from the same data, so nothing appears there that a browser is not shown.
  • "Not stated" is not a "no". It means the sources are silent.

STEP 05

Read the demand signals

What was asked, how the door fared in buyer evaluations, and which requirements it failed, all aggregated. "What no door had" lists the requirements not one of the doors interviewed for that request could meet.

  • The Free plan sees the aggregates. Full question texts and the exact requirements you failed are shown on Pro.
  • What is stored about an asker is a daily-salted hash of their IP address — not the address itself, and no name or email.
  • Contact details appear only for buyers who agreed to disclose them, and only to a paid-plan door.

STEP 06

Accept a meeting

A buyer who evaluated your door proposes a meeting. Accepting brings their name and contact, their candidate times and the list of points their evaluation left open. Reply to the buyer with the time that suits; once the buyer confirms it, you get a notice that the date is fixed. Until you accept, the buyer is not identified.

  • On the Free plan the success fee is ¥15,000 per meeting you accept whose date is fixed. The first one is free.
  • On Free, a card has to be on file before you accept; registering it charges nothing.
  • Proposals, declines, buyer passes and meetings without a fixed date are never billed.
  • Cancel within the same calendar month (JST) as the date was fixed and nothing is charged.
  • The buyer fixes the date: it is fixed when the buyer confirms one of their candidate times.
  • When you accept, AgentDoor sends the buyer one email (if the proposal form showed them this notice), to the address they entered in the form, saying you accepted and how to fix the date on their results page. Your contact details and prices are not in it.

Buyer side

Running an evaluation — five steps

Same rule on this side: the screens carry the strings the product ships. The requirements shown are an example need.

STEP 01

Describe the need in plain language

No RFP template, no procurement portal. One or two sentences — the way you would tell a colleague — become a structured requirement set. Your contact details are stored only if you tick the box.

  • One or two sentences is enough (10–2000 characters).
  • No account needed, and buyers use it free.
  • To prevent abuse, the number of requests is rate-limited.

STEP 02

Interview the matching doors with the same five questions

Your agent knocks on the matching doors at once and puts the identical five questions to each of them — up to 8 doors per request. Answers come from that vendor's approved sources only, and cite the sources they used.

  • 5 fixed dimensions — the same set of questions for every vendor.
  • Only the question text reaches a door's agent. Never your request text, never your contact details.
  • A door that could not answer is shown as "No answer" — that is information too.

STEP 03

Ask again only where it is still open

For requirements the first pass scored partial or unknown, your buyer-side agent writes follow-up questions and puts them back to the door. If any come back answered, that door alone is re-scored.

  • At most 3 follow-ups per door, one round.
  • Only unresolved requirements are re-asked; settled verdicts are left alone.
  • If the follow-up round fails, the first scoring stands.

STEP 04

Compare on the fit matrix

Every requirement, every vendor, in four states. Ruled-out candidates carry the reason; a candidate that missed on a single required item is kept as a near miss. Requirements no door met are shown as such.

  • "—" means not stated in the vendor's sources. It is kept distinct from "does not meet".
  • When a vendor updates its sources, requests from the last 30 days (up to 20) are re-graded, and a request whose verdicts moved shows them as "Corrections". Email goes only to buyers who agreed, when making the request, to be told about result updates.
  • When a vendor answers a question left open, the request is re-scored automatically.

STEP 05

Download an approval document you can circulate

The result exports as a Word ringi document: 7 numbered sections and an appendix of the 5 questions approvers usually ask. Every figure and verdict comes from the interview answers and their citations.

  • Only facts present in the interview results are written. No annualising, no arithmetic of our own.
  • The document states in writing that "not stated" is not a negative finding.
  • Downloading the ringi document has no count limit and no charge.

What agents do, and what they do not do

Agents exchange information; people decide. A door answers only from sources its vendor approved, and says so when the sources are silent — silence is never turned into a no. A buyer's agent asks and compares; it signs nothing, and a door's agent never receives the buyer's request text or contact details, only the question. The vendor gets the questions and the requirement labels; a vendor on a paid plan also sees the first 200 characters of the request text as written, contact details included if you typed them there, whether or not you agreed to share contact details. Contact details you enter in the contact fields reach a vendor only when the buyer agrees to share them, or when the vendor accepts a meeting the buyer proposed. An answer cites the approved sources it used.

Frequently asked questions

How long does an AgentDoor evaluation take?
The interviews run in parallel, and the results page opens as soon as they finish — the form tells you it can take about a minute. How long depends on how many doors match your need and whether their answers are already cached; where a door has answered the same fixed question before, the stored answer is returned without calling the model again.
What if a vendor's door can't answer a question?
The row is shown as "No answer" or as not stated in the vendor's sources — never guessed at, and never read as a no. The vendor sees the same question in their manage screen under unanswered questions; when they answer it, the answer is saved as an approved source and your request is re-scored.
Do I have to sign up to evaluate vendors?
No. Buyers describe a need on AgentDoor with no account, and buyers use it free. Vendors need a door so there is something to interview, and creating one needs no account either — the management link is shown once, right after creation.
