Can you use AI for bid writing?

Yes, most tenders let you draft a bid with AI, because the buyer judges the response you sign, not the tool that drafted it. For a given bid, three things decide it. They are the buyer's AI instructions, what the tender's terms and data protection allow you to paste into a tool, and whether you can back every claim the tool drafts.

The buyer's instructions decide first

Read the instructions to bidders for anything on AI before a writer drafts in ChatGPT, because the buyer's own terms settle what you may do on that bid. Buyers set their own rules for AI in tender responses. Where a tender sets none, the other two conditions decide.

In UK central government, the Cabinet Office's Procurement Policy Note 017 (PPN 017) says a supplier's use of AI is not prohibited during the commercial process. It tells buyers to weigh the risks as they would if you had used a bid writer. The note's published text also lists asking suppliers to disclose their use of AI in creating their tender as a step buyers may take. Its example questions ask the supplier to confirm that AI-supported answers were checked and verified for accuracy. Elsewhere in Europe, you work from the tender's own clauses.

Those clauses vary by buyer. A tender can cap the share of the response AI may write, or require a person to sign off every element before submission. It can also ask in a qualification questionnaire whether AI was used and what share it wrote. Each of these changes how you staff the draft.

Take a bid manager whose writers have drafted the method statements for a facilities services tender in ChatGPT. If the instructions require sign-off on every element, a named reviewer goes on each answer when the plan is made, not at the final read. If they cap AI's share, the writers need to know which answers may carry AI text before they start.

What the tender's terms let you paste in

The tender's confidentiality terms and your own information security rules decide what goes into ChatGPT, Claude or any other tool. Check both before anyone pastes in the buyer's documents, because tender documents are often confidential, and CVs and case studies carry personal data.

Back on the facilities services bid, a writer wants to paste in the specification and the proposed contract manager's CV to draft the mobilisation answer. The specification is the buyer's confidential information. Ask your security team whether the tool, as your organisation has set it up, keeps pasted material out of model training. Before that, read each part of the tender for what it keeps confidential.

The CV is personal data. Under the EU GDPR, the controller has to build data minimisation into how it processes personal data. The writer therefore pastes in the experience the answer needs, not the contact details or the full career history.

Every AI-drafted claim is yours at sign-off

The bid manager answers for every response, whoever drafted it, so a claim the tool wrote becomes your claim at sign-off. What a response commits you to doesn't change because a model produced the sentence.

The danger is a claim that reads well and is wrong. In the facilities services bid, the case study draft names a certification and describes a past contract. Both read as fact. Neither is fact until someone traces it to a certificate or a contract record.

Where the claim sits decides what it costs you. In a scored answer, an unsupported claim weakens the response. In the selection answers, it can cost you the bid. Under Directive 2014/24/EU, as each member state implements it, a buyer may exclude a bidder for serious misrepresentation in the information supplied to verify the selection criteria or the absence of exclusion grounds. The same applies to a bidder that withholds that information. An unchecked AI claim about turnover, insurance or accreditation is a selection risk as well as a quality risk.

So send the checking where the stakes are. Send certifications, contract references, figures and delivery commitments to the person who owns the evidence before sign-off, not the proofreader.

A rule for using AI on your next bid

Use AI on any bid whose instructions allow it, provided you can say at submission which answers it drafted and who verified each one. If the buyer asks you to confirm that AI-supported answers were checked, a team without that record can't honestly do so.

Work in this order:

1. Clear the tool with security and legal for confidential documents and personal data before the bid starts.
2. Read the instructions to bidders for AI clauses, and assign reviewers to meet any sign-off rule or cap on AI's share.
3. Paste in only what the confidentiality terms allow, and only the personal data each answer needs.
4. Record, per answer, whether AI drafted it and who verified it.
5. Trace every claim of fact to its record before sign-off.

In SEQUESTO's agentic operating system (aOS), each draft answer from James shows the reasoning behind it, and every agent invocation, edit and approval is logged with actor, timestamp and item. The record of what AI drafted and who approved it therefore exists at submission. For what reviewers need to see before they sign, read about auditable AI bid writing. For the process this rule sits inside, read about bid management.

Start with the bid on your desk. Open its instructions, find any AI clause, and name who verifies each answer before the first draft.
