What Must Remain the Applicant’s Own Intellectual Contribution in an AI-Assisted Grant Application?

How Much of a Grant Proposal Must Be the Researcher's Own Work?

You ask generative AI to help prepare a research grant application. Initially, the tool improves the wording of your objectives and organizes your methodology. Later, it suggests new research questions, proposes an alternative design, develops arguments about the project's significance, and drafts substantial sections of the application.

At what point does AI assistance begin to compromise the applicant's original intellectual contribution?

The issue is more consequential than whether individual sentences were written by a human or generated by a model. A research grant application represents a proposal for scientific work that the applicants are expected to understand, justify, and carry out.

Some funding organizations have also established explicit restrictions concerning applications substantially developed by AI. Researchers therefore need to distinguish assistance with communicating their ideas from delegating the substantive development of the proposed research.

The Applicant Must Retain the Substantive Scientific Contribution

Understanding Intellectual Contribution in AI-Assisted Grant Preparation

What Counts as an Intellectual Contribution to a Research Grant?

A research grant proposal does more than describe a topic. It presents a scientific argument about what should be investigated, why the investigation matters, how the research will be conducted, and what its findings could reasonably contribute.

Intellectual contribution therefore involves substantive decisions that shape the proposed research.

These may include identifying an important unanswered question, developing a defensible conceptual framework, selecting an appropriate research design, establishing analytical strategies, and explaining the contribution relative to existing scholarship.

Such contributions are not always made by one person. In collaborative applications, different investigators may contribute specialized knowledge, methodological expertise, preliminary evidence, or project design decisions.

The important distinction is between intellectual work undertaken by the research team and content produced by an AI system without sufficient researcher-led development or justification.

Why Intellectual Contribution Is Different From Writing the Words

The person who types a sentence is not necessarily the person who developed the idea it expresses.

A researcher might independently design an experiment and use AI to improve the clarity of its description. In that situation, the tool assists with communication rather than originating the experimental design.

Conversely, an applicant might ask AI to invent an entire research project, generate its hypotheses, select its methods, and formulate its expected contribution. Rewriting the resulting text in the applicant's own words would not necessarily transform the underlying intellectual development into the applicant's original work.

This distinction is especially relevant when a funder restricts substantial AI development rather than merely the presence of AI-generated wording.

Researchers should therefore examine who developed and justified the substantive scientific decisions, not simply whether the final prose sounds human-written.

Which Parts of a Grant Proposal Require Applicant-Led Scientific Judgment?

The following distinctions provide a practical framework for evaluating intellectual contribution. They are not universal legal definitions or automatic classifications under every funding policy.

The acceptability of a particular form of assistance must still be determined from the applicable funder policy. A task described as possible AI assistance is not automatically permitted by every funding organization.

What Does NIH Mean by Substantially AI-Developed Applications?

On July 17, 2025, the US National Institutes of Health (NIH) issued Notice NOT-OD-25-132, titled Supporting Fairness and Originality in NIH Research Applications.

The notice states that NIH will not consider applications, or sections of applications, substantially developed by AI to represent the applicants' original ideas. The policy applies to applications submitted for receipt dates beginning September 25, 2025.

NIH acknowledges that AI tools may be appropriate for limited aspects of application preparation or in specific circumstances, while emphasizing risks involving plagiarism, fabricated citations, and research integrity.

The policy does not establish a universal percentage of AI-generated words that automatically determines whether an application is substantially developed by AI.

Consequently, researchers should not assume that replacing a certain proportion of AI-generated text, paraphrasing every sentence, or passing an AI-text detector establishes compliance.

The substantive development of the proposal and the applicable official guidance are more relevant than an arbitrary word-count threshold.

Can AI Suggest Research Ideas Without Becoming the Intellectual Author?

AI-generated suggestions can function as exploratory material. Researchers may encounter alternative research questions, methodological possibilities, or conceptual connections during AI-assisted brainstorming.

However, the acceptability of using those suggestions in a grant application depends on the funding policy and the nature of the subsequent intellectual work.

A researcher who independently investigates a suggestion, evaluates the literature, develops the scientific rationale, and constructs a defensible study may make substantial intellectual contributions to the resulting project.

That does not establish a universal safe harbor under policies restricting substantial AI development. The origin and extent of the AI contribution may still matter.

Applicants should therefore avoid treating AI-generated research ideas as automatically original merely because they subsequently edited or expanded them.

Does Choosing Between AI-Generated Options Count as Intellectual Contribution?

Selection can involve meaningful scientific judgment, but its significance depends on what the researcher actually contributes.

For example, evaluating several methodological alternatives against the research question, available evidence, and practical constraints requires expertise.

Nevertheless, selecting one of several complete AI-generated proposals does not necessarily mean the applicant independently developed the selected research idea.

Researchers should be able to explain why a particular approach was chosen, what alternatives were considered, and how the final design emerged from their scientific reasoning.

Where the funder restricts substantial AI development, the applicant should also verify whether the process itself is permissible.

Can AI Help Develop a Methodology Without Replacing the Researcher's Judgment?

AI may be useful for explaining established methods, identifying assumptions, or suggesting issues that deserve further investigation.

For example, a researcher planning a mixed-methods study might ask AI to explain the differences between explanatory sequential and convergent designs.

Such assistance can support methodological understanding. The researcher must still determine which design is appropriate and justify that decision using relevant methodological literature.

Problems arise when applicants adopt AI-generated procedures they cannot adequately explain, defend, or implement.

A method that appears technically sophisticated in the proposal may be unsuitable for the actual research question or unavailable resources.

Ultimately, methodological decisions must reflect the research team's competence and the scientific requirements of the proposed investigation.

Why Human Verification Is Necessary but Not Always Sufficient

Applicants should verify AI-assisted content for factual accuracy, methodological coherence, and consistency with the funding call.

However, verification and intellectual origination are not identical.

A researcher might carefully check a research plan generated almost entirely by AI and determine that it contains no obvious factual errors. That review does not automatically establish that the applicant originated the underlying scientific ideas.

Conversely, a researcher may independently develop an original project but use AI to improve how it is described.

These situations differ in the nature of the intellectual contribution, even if both involve substantial human editing.

The distinction is particularly important when interpreting funding agency restrictions on AI-assisted applications.

Can AI Be Listed as a Principal Investigator or Research Team Member?

Generative AI systems cannot ordinarily fulfill the institutional, legal, and professional responsibilities associated with serving as a principal investigator or named research team member.

Principal investigators and other responsible personnel must satisfy the funder's eligibility rules and undertake obligations concerning project implementation, financial stewardship, research integrity, and reporting.

An AI system cannot independently assume those responsibilities or be held accountable through the same institutional arrangements.

AI assistance should therefore be distinguished from the contributions and responsibilities of human investigators.

How Does Intellectual Contribution Work in Collaborative Grant Applications?

Collaborative research often involves distributed intellectual contributions. A principal investigator may establish the overall research direction, while co-investigators develop specialized methods, theoretical perspectives, or implementation plans.

The proposal can remain an authentic research-team contribution even when no single applicant originated every component.

However, collaboration does not eliminate the need to identify whether substantive sections were developed by AI in a manner inconsistent with the funder's policies.

Research teams should establish shared expectations about permitted AI assistance and ensure that all responsible investigators understand the final scientific plan.

Why Originality Cannot Be Established by an AI-Detection Score

AI-text detection systems attempt to classify text based on statistical or other indicators. They do not directly determine who originated a research idea, selected a methodology, or made a scientific decision.

A researcher could independently develop a project and then use AI-assisted language editing, producing text that a detector might classify as AI-generated.

Conversely, substantially AI-developed ideas could be rewritten in language that a detector classifies as human-authored.

Therefore, an AI-detection score should not be treated as definitive evidence of intellectual contribution.

Researchers should maintain accurate records of substantive development and follow the funder's actual requirements rather than attempting to optimize a detector result.

Why Disclosure Does Not Resolve Every Originality Concern

Disclosure can make AI assistance more transparent, but it does not automatically establish that the underlying activity was permissible.

If a funding organization restricts applications substantially developed by AI, acknowledging that substantial AI development occurred does not necessarily satisfy the originality requirement.

Similarly, a statement that the applicants reviewed all AI-generated material does not establish that the research idea or methodology originated with them.

Researchers should therefore distinguish disclosing AI assistance in a grant application from demonstrating that the proposal represents the applicants' genuine intellectual contribution.

Distinguishing AI Writing Assistance From AI-Developed Research

Researcher A's use is primarily editorial and evaluative. The substantive scientific decisions were developed independently, although the researcher must still confirm that the assistance is permitted under the applicable funding rules.

Researcher B's application raises more serious originality concerns because AI generated much of the scientific content. Reviewing and lightly revising the result does not automatically establish that the proposal represents the applicant's original intellectual work.

Under a policy such as NIH's restriction on substantially AI-developed applications, the second approach would require particular scrutiny and may be impermissible.

The comparison illustrates why the amount of AI-generated wording alone is an inadequate measure of intellectual contribution. The origin and development of the research decisions matter.

Misconceptions About Originality in AI-Assisted Grant Applications

How to Preserve Your Intellectual Contribution While Using AI

The most defensible approach is to establish the researcher's substantive contribution before using AI for consequential proposal development.

Develop the central research problem, objectives, methodological rationale, and expected contribution through independent scholarly work and collaboration with qualified investigators.

AI can then be considered for permitted tasks that support explanation, organization, or critical examination without replacing the research team's scientific decisions.

Document How the Scientific Decisions Were Made

Researchers may find it useful to retain records showing how the proposal's objectives, design, and rationale developed.

These records can include literature notes, methodological discussions, preliminary analyses, research-team decisions, and relevant AI interactions.

The purpose is not to create an artificial appearance of originality. It is to preserve an accurate account of the work that actually occurred.

Such documentation may also improve collaboration by clarifying which investigators contributed to different components of the application.

Use AI to Strengthen Reasoning Rather Than Replace It

A productive role for AI is to challenge the researcher's existing reasoning.

For example, a researcher may ask AI to identify assumptions in an independently developed methodology or question whether the proposed data can support the intended conclusions.

This form of assistance can prompt useful reflection without requiring the model to originate the entire research plan.

Even then, the applicant must evaluate the criticisms independently and confirm that the activity is permitted.

The same principle applies when using AI to identify weaknesses in a grant proposal. The value lies in supporting the researcher's judgment rather than substituting for it.
