Ask once. The answer stays.

A question you answer well is worth more than a post you write well — so CHiiRO keeps the answers and lets the posts scroll away.

The half-life problem

A good answer in a chat room has a half-life of about four hours.

Somebody explains, carefully, why a 2% option pool top-up at the seed round is normal and a 12% one is a signal — and then the room moves on and it's gone. The next person asks the same question next month and gets a worse answer from whoever happens to be awake.

The knowledge archive is the fix: a question has a page, an answer has a permanent home, and the version everyone agreed was right is marked as accepted and sits at the top. The work of answering only has to be done once.

How a question works

Context is what gets a specific answer.

You ask with enough context to be answerable — the stage, the constraint, what you already tried. People answer. Answers can be voted on, and the person who asked can mark one as accepted, which is the strongest signal in the system because it comes from the only person who knows whether the answer actually worked.

You can follow a question to hear when it moves, and pass on one you can't help with so it stops surfacing for you. Media attaches to both questions and answers, because sometimes the answer is a screenshot of a clause.

The correct ordering for a reference, not a feed.

Ranked by usefulness, not by recency

The archive is ranked, not chronological. A question from three months ago with an accepted answer and strong votes outranks one from this morning with none — which is the correct ordering for a reference and the wrong ordering for a feed, and it is why the two are separate products.

Topics sit in a real hierarchy, so a question about convertible notes is reachable from fundraising, and reachable by someone searching for the plain-English phrasing rather than the term of art.

Read it without an account

The strongest SEO asset the product has.

The archive's read paths are open. You can land on a question from a search engine, read the question and the answers, and decide whether CHiiRO is worth installing — without a signup wall in front of the one thing that would convince you.

That is also why the archive is the part of CHiiRO a search engine and an answer engine can actually see.

What's AI-written, and how you know

Labelled at the source. Every time.

Part of the archive is AI-authored seed content. Every piece of it is recorded as AI-authored in the database at the moment it's created — not tagged afterwards, not inferred.

Where an answer's origin is genuinely unknown, CHiiRO shows nothing rather than letting the absence of a label imply a human wrote it. You can read the full record on the disclosures page.

Questions and answers

Q.What is the CHiiRO knowledge archive?

It is a question-and-answer archive for people building companies. Questions have permanent pages, answers can be voted on, and the person who asked can mark one as accepted. It is ranked by usefulness rather than recency, and its read paths are open without an account.

Q.Can I read CHiiRO questions without signing up?

Yes. The question and answer read paths are open, so you can arrive from a search engine, read the full question and every answer, and decide afterwards whether to install the app. Asking a question or answering one requires an account.

Q.How are answers ranked on CHiiRO?

By usefulness rather than by time. Votes and an accepted-answer mark from the person who asked carry the ranking. That ordering is right for a reference archive and wrong for a feed, which is why CHiiRO keeps the archive and the discussion feed as separate things.

Q.Are CHiiRO answers written by real people?

AI-written material is recorded as such in the database when it is created. Content whose origin is unknown is never shown as human-written.

Q.What makes a good question on a startup forum?

Context. The stage you are at, the specific constraint, and what you already tried. A question with those three things gets a specific answer; a question without them gets generic advice that was already free everywhere else. CHiiRO's archive is built to reward the first kind.
