Someone sent you a document to review. You can hand the whole job to your AI.

A PitchStation review link — a contract, a proposal, a webpage — lets you comment directly on the document: select text to object to it, propose replacement wording, pin visual issues. No account, no signup. And if you work with an AI assistant — Claude Code or Codex in a terminal, or plain claude.ai / ChatGPT in the browser — you can hand it the link and let it do the reading and the commenting as you. This page shows every path.

§01The 30-second version

That's genuinely all a recipient needs. The rest of this page explains what happens, what your AI can and cannot do, and how to review by hand.

§02What your AI actually does

Every review-enabled share is self-describing to AI agents. The page carries a machine-readable pointer to a guide at /s/<slug>/review-guide — protected by the same access key as the document itself — which teaches the agent the full loop:

1. Read the document. The share URL returns the real HTML (for a multi-file bundle, each file is listed and readable individually).
2. Identify as you. Comments need a human name behind them. The agent registers the name you gave it once; every comment it posts is attributed to that name, marked (unverified) so the owner knows it wasn't a signed-in account.
3. Post comments anchored to exact text. A comment on a clause quotes that clause verbatim. The server verifies the quote against the document before accepting it — if the AI paraphrases, the comment is rejected with instructions to re-read and copy exactly, so a sloppy quote can never produce a comment that points at nothing.
4. Propose replacement wording. For contracts, the strongest move: a suggested edit shows the current wording and the proposed wording side by side, and the owner can accept or reject it with one click.
5. Read the discussion. The agent can poll the thread to see the owner's replies and the status of each point (open / resolved / accepted / rejected).

§03Using web claude.ai or ChatGPT (no terminal)

Browser chatbots can read the shared page (their browsing tools fetch URLs) but cannot post — they have no way to call the comment API. So the flow has one extra step: the AI writes the review as a structured block, and you paste it into the page, where every quote is verified and nothing publishes until you confirm.

§04Reviewing a contract with AI

For a contract or agreement, tell the AI what your position is — it reviews on your behalf, so it needs your instructions, not just the document:

What happens across revision rounds

When the owner revises the document, it stays at the same link and your comments come along:

Your AI can read the changes too: /s/<slug>/changes (same access key) returns every round’s note and a redline — - removed / + added paragraphs — between rounds, so a returning agent knows exactly what moved without re-reading the whole document. The machine guide points agents at it automatically.

Returning to the link after a revision shows an "updated since you read it" banner with the owner's note about what changed — a natural moment to run your AI over it again: "the document was revised — re-read it, check which of my points were addressed, and comment on anything new."

§05Reviewing a webpage or design

Shared webpages (including multi-page sites shared as a bundle) take the same comments, plus visual ones:

• Numbered pins — in Annotate mode, click any element (a button, an image, a heading) to drop a numbered marker and comment on that spot.
• Drawn boxes — drag to outline a region ("too much whitespace here").
• Viewport context — every comment records the screen width it was made at, so "the menu is broken" made on a phone is understood as mobile-layout feedback.
• Per-page threads — on a multi-file bundle, comments attach to the page they're about.

§06Reviewing by hand

Open the link and look for the mode bar in the bottom-right corner. The ? button in the panel header shows this same cheat-sheet — plus a "Copy the AI prompt" button that produces §01's prompt with the link already filled in, and "Paste an AI review" for the §03 flow.

The first time you comment you'll be asked for a name. That's the entire signup. On a translated view (the Translate pill), the widget will ask you to switch back to the original before commenting — comments anchor to the original text so they survive revisions.

§07Good to know

• The owner sees everything in one feed — your comments, your AI's comments, and other reviewers', each attributed. There is no private draft state: posted means visible.
• Check what your AI posted. It signs your name. Open Threads after it runs; you can edit or delete your own comments (same browser/session — your identity lives in a cookie the AI's session also holds if it kept its cookie jar).
• Rate limits are enforced per reviewer per document. If your AI hits one, it should stop and tell you rather than retry in a loop — the guide instructs it to.
• Don't paste the link anywhere public. The URL contains the access key; anyone holding it can read the document and comment. Treat it like the document itself.
• You can review in your own language — comments may be written in any language; only quoted text must match the original document.
• Plain text only in comments (up to 4,000 characters). Markdown isn't rendered.

§08For senders: enabling this

Turn on document review when you publish (or later — same link):

The owner’s AI loop: gather, draft, decide

You don’t read the feedback by hand either. On your share’s analytics page, the Review section has a 🤖 Use your AI button with a ready prompt for whichever AI you use — each one reads the comments, drafts the revision, and keeps you in control of what publishes:

Then tell your recipient one sentence: “Comment directly on the page — or if you use an AI assistant, paste it the link and ask it to review; it will find the instructions itself. Guide: pitchstation.ai/ai-review-guide.html”. Your own AI reads the same discussion via pitchstation_comments and publishes revisions with pitchstation_replace — so a full negotiation can run assistant-to-assistant, on the record, with both principals in control.
