Drop the questionnaire.
See the first ten answers before you sign up for anything.

Most of a security questionnaire is the same twenty controls asked four different ways. Prelude reads yours, shows you exactly how much of it is repetition, and drafts the first ten answers from your own whitepaper — cited, with the gaps flagged rather than guessed.

▸ Your file never leaves this tab

The spreadsheet is parsed in your browser. Not uploaded and deleted — never uploaded. Open the network tab and drop the questionnaire: you will see zero requests.

▸ Nothing you send is stored

When you ask for answers, the questions and your source text are held in memory for that one request and dropped when it ends. No database row ever holds what you send us. We do keep counters, and this page carries analytics like the rest of the site — what those are is on the trust page ↗.

▸ No training, ever

Answers are drafted by Anthropic under a zero-retention agreement. Your content is never used to train a model — ours or anyone else's. The full posture ↗

A PDF or DOCX is read by a parser this page fetches from this site the first time you add one, so you will see a script load. It runs here: your document is opened in this tab and none of its content is sent anywhere.

This is the only thing on this page that sends anything you gave us. When you press it, 10 questions and the text extracted from your documents go to our answering service and on to Anthropic — as text. Your files stay here.

Five steps, and only one of them sends anything you gave us.

Worth reading if you are the person who has to sign off on sending a customer's questionnaire to a vendor's website. This is the whole data flow, including the one step that fetches code from us rather than sending anything to us.

01 · YOUR BROWSER

The file is read locally

The spreadsheet parser runs in this tab. The file itself is never sent anywhere, in any form.

02 · YOUR BROWSER

The analysis is arithmetic

Duplicate clustering and the boilerplate split are deterministic — no model involved, so a visitor who stops here has sent nothing at all.

03 · YOUR BROWSER

Your document is opened here

Adding a PDF or DOCX fetches the matching parser from this site — a script, from our origin, so you will see it load. It runs in your tab; no part of the document is sent.

04 · ONE REQUEST

Text goes, files don't

Press the button and ten question texts plus the text extracted from your document go out — used for that request and dropped when it finishes.

05 · YOUR BROWSER

The run waits here for you

Answers are held in this browser for seven days so signing up can pick them up. Same device only — they never left it.

The other ninety questions
are the same job.

A trial runs the whole questionnaire against your own Vault — your approved answers, your past RFPs, your voice — and exports back into the original spreadsheet, in place.
