How your tender documents are read
Every document you add to a bid is read by our own software. While AI reading is on for your company, it is also read by an AI model, which finds more. This page says how that works, how many pages you are given, what it gets wrong, and how to turn it off.
Last updated 19 October 2026.
What happens to a document
Our own software reads every file you add, whatever plan you are on. It lists the dates and requirements it finds, each with the line it came from.
Each reading finds things another missed, so the buyer's document is read three times and the findings are put together. Something found more than once is listed once. Everything it adds is marked “read by AI” and shows the lines of your document it came from.
A long file is read in sections, all of them, up to 800 pages of one file. A file longer than that says on the document how much was read.
Nothing is ticked off for you, and AI reading does not decide whether you can bid. It is there so that less gets missed. It does not replace reading the buyer's documents.
How many pages you are given
AI reading is included. There is no charge for it on any plan, and nothing to pay for reaching the limit.
| A company on no plan | 600 pages in all |
| Watch | 3,000 pages every month |
| Bid | 12,000 pages every month |
| Win | 40,000 pages every month |
What a page is. 2,500 characters of text. A dense page counts for more than one, and a drawing with no text counts for none. A page read three times counts once.
When you run out. A document that would take you over what is left is not sent to the AI model, and the document says so. Our own software still reads it. On a plan, the count starts again on the first of each month. On no plan, the pages are a total and do not start again.
On no plan, on a busy day. We limit how much AI reading is done in a day for companies on no plan. A document held back that way says so, and you can send it the next day. This never affects a company on a plan.
The number of pages your company has used is shown inside your account, under Company, AI reading.
What it finds, and what it misses
We tested both readers on real public tenders neither had seen. What each tender requires was written down first, separately, and both readers were scored against that list.
| What was looked for | Found with AI reading | Found without |
|---|---|---|
| What an English tender requires | 141 of 149 | 57 of 149 |
| What a French tender requires | 59 of 59 | 13 of 59 |
| The closing date in a French tender | 19 of 19 | 8 of 19 |
| What an English addendum changes | 22 of 23 | 17 of 23 |
| What a French addendum changes | 17 of 29 | 16 of 29 |
It still misses things. French addenda are its weakest result. Read the addendum itself before you rely on what is listed from it.
It sometimes files a real line under the wrong heading. Of 352 things it listed in that test, 36 were not right, most of them a real line of the document under the wrong heading. None of the figures it gave for an English tender was wrong. Check what is listed against the file.
How far to trust these numbers. The lists the readers were scored against were written by a separate AI reader that could not see ours, and so were the rulings on what counted as right. No person has checked them.
Public tender notices are read this way too
A public notice is the buyer’s own summary of a tender. It is the same for every company, so it is read once for everybody and uses none of your pages. We read it ourselves, it is read by AI four times, and a stronger AI model then checks every finding against the whole notice, including the ones our own software found.
What the check confirms is listed on the tender as a requirement, marked as read by AI where a reading found it. What it does not confirm is kept under “Also mentioned in the notice”, with the line it came from, and does not change the result. A notice often says a thing may be required. That is worth seeing and is not a reason you cannot bid.
A reading never closes a tender to you. We cannot tell from a notice whether your company meets something only an AI model read there, so it can make a tender worth a look and no more than that.
What it was measured to do. On 120 public notices none of the readers had seen, 148 of the 152 things the check confirmed were right. Of 200 requirements written down from those notices, 174 were on the screen: 129 confirmed, and the rest as a line to check. Our own software by itself found 57, and was right 66 times in 86. It still misses things, so read the notice.
A notice that has not been read this way yet shows what our own software found. The text sent is the buyer’s published notice. Nothing about you or your company goes with it.
Who the text is sent to
What is sent. The text of each buyer’s document you add to a bid while AI reading is on: a tender, a specification, an addendum, a bid form, a contract. A supplier’s or subcontractor’s quote, a price list, a takeoff, your costs, your company profile and anything about your people are never sent by AI reading. A bid your company wrote is sent only if an owner turns on AI review of bids, a separate switch that is off until they do, and only the files added as the bid.
On the form for a tender you found. When you drop a tender’s documents on that form, their first pages are sent once, to fill in the reference number, the title, the buyer and the closing date for you to check. Those pages are not counted against your allowance. The documents are read in full, and counted, when you add the tender.
Who gets it. Anthropic, PBC, a United States company, which runs the model that reads it (Claude Haiku 5.5). It may be processed in the United States or in another country Anthropic operates in.
What they may do with it. Anthropic's published terms for business customers say it may not train its models on what we send. Anthropic says it deletes what it is sent, and its answers, within 30 days, except where content is flagged as breaking its usage rules or the law requires it to be kept. Those are Anthropic’s terms as we read them on 12 October 2026, and theirs to change: anthropic.com/legal/commercial-terms.
Your documents and what is read out of them stay inside your company. They are never shown to another customer.
Turning it off
AI reading is on from the day a company is set up. A company set up before 13 October 2026 has it off until one of its owners turns it on.
An owner of your company account can turn it off at any time, under Company, AI reading. Nothing further is sent from that moment. What was already sent is deleted on Anthropic’s schedule above, and what was already added to your bids stays, marked as read by AI.
Where a buyer has told you a document may not be passed to anybody else, turn AI reading off before you add it.
