Write a Manuscript

Draft a scientific manuscript from study data and references, with AI support for structure, section drafting, and synthesis.

~30 min with AI per section, ~2–3 hours without Expert review required. All claims must be verified against source data before submission.

Study data + references → Outline → Section drafting → Synthesis and review → Submission-ready manuscript

Best for

• Drafting original research manuscripts from clinical study data
• Writing review articles or narrative reviews from a defined evidence base
• Preparing conference papers or short communications
• Publication support drafting where the medical writer works from a data package and author input
• Creating first-draft sections (Introduction, Discussion) to accelerate the authoring timeline

Inputs

• Study data (CSR, data tables, statistical outputs, or published results)
• Reference library (full text of key citations)
• Author guidance on narrative direction, key messages, and target journal
• Target journal author guidelines (word limits, section structure, reference style)
• Any existing outline or messaging framework

Steps

1. Confirm the outline and narrative

   Start from an approved outline or build one using the Build a Content Outline workflow. The outline should define what each section covers, which data supports it, and the overall narrative arc. Do not start drafting without an agreed structure.

2. Draft the Methods section

   Methods is the most mechanical section and the safest starting point for AI. Provide the study design details and let AI structure them into standard reporting format. Verify against the protocol or CSR, not just the data tables.

3. Draft the Results section

   Provide the statistical outputs and data tables. AI structures the results into text, tables, and figure legends. Verify every number. This section has the highest density of values that can be transposed, rounded, or misattributed.

4. Draft the Introduction

   Provide the key references and context. AI generates a structured introduction that positions the study within the existing evidence. Check that every contextual claim cites a specific reference and that no background information comes from AI training data.

5. Draft the Discussion

   This is the section requiring the most human input. AI can structure the discussion around key findings, but the interpretation, clinical implications, and limitations require author and medical writer judgement. Use AI for a structural first pass, then rewrite substantially.

6. Compile and verify

   Assemble all sections. Run Verify Claims Against References on the full manuscript. Check internal consistency (do the Results match the Abstract? do the Discussion conclusions match the data?). Confirm the manuscript meets the target journal’s guidelines.

Output

A complete manuscript draft in IMRaD format (or journal-specified structure) with all sections populated, data accurately represented, references correctly cited, and internal consistency maintained. The draft is ready for author review and revision, not for submission. No manuscript drafted with AI support should be submitted without thorough author review and sign-off.

Prompt pattern

You are a medical writing assistant supporting manuscript development. Draft the [SECTION] of a manuscript based on the following materials.

Section to draft: [INSERT: Introduction / Methods / Results / Discussion]
Target journal: [INSERT journal name and any specific formatting requirements]
Word limit for this section: [INSERT]

Key points this section should cover:
[INSERT OUTLINE POINTS FOR THIS SECTION]

Source materials:
[INSERT RELEVANT DATA, REFERENCES, OR STUDY DETAILS]

Rules:
- Base all content on the provided source materials only.
- Reproduce data points exactly as stated in the source.
- Cite references using numbered superscripts [1], [2], etc.
- Do not add background information from your training data.
- If a contextual claim needs a reference you do not have, insert [REF NEEDED].
- Use formal scientific writing style appropriate for peer-reviewed publication.
- Flag any content you are uncertain about with [VERIFY].

Customisation: Draft one section at a time for better control. For the Discussion, provide a list of key findings to address and any author-specified interpretation points. For review articles, adjust the prompt to synthesise across multiple sources rather than reporting a single study.

Why this works

AI accelerates the mechanical parts of manuscript drafting: structuring Methods from a protocol, converting statistical tables into Results text, and organising Introduction references into a coherent narrative. These are time-consuming tasks where the content is largely determined by the source data. The human writer and authors handle the parts that require scientific judgement: interpreting results, contextualising findings, acknowledging limitations honestly, and ensuring the manuscript tells a coherent story that the data actually supports.

Common mistakes

Unsourced claims in the Introduction

AI adds a sentence about disease prevalence or standard of care from its training data, not from a cited reference. Every factual statement in the Introduction must cite a specific source. Insert [REF NEEDED] for any claim that lacks a citation, then find the reference or remove the claim.

Results that do not match the data

AI converts a data table into prose and transposes the treatment and placebo arm results. The Results section has the highest error density in AI-assisted drafts. Verify every number against the original statistical output or data table.

Discussion that overstates findings

AI writes “This study demonstrates that Drug X is superior to standard of care” when the study was powered for non-inferiority. The Discussion must reflect exactly what the data shows, using the same language the statistical analysis supports.

Internal inconsistency across sections

The Abstract reports a different p-value than the Results. The Discussion references a secondary endpoint that is not mentioned in the Results. After assembling all sections, read the manuscript end-to-end and cross-check key values across sections.

Skipping author review

A manuscript drafted with AI support is a working draft, not a finished paper. Authors must review the scientific content, interpretation, and conclusions. The medical writer’s role is to produce an accurate, well-structured draft that gives authors a strong starting point for their review.

Frequently asked questions

Can AI write a full manuscript from scratch?

No — not to a standard suitable for submission. AI can draft sections from source material you provide, but the scientific judgement that holds a manuscript together (what to include, how to frame it, how cautiously to interpret findings) is a human responsibility. Use AI as a drafting tool, not an author.

Which sections of a manuscript are safest to draft with AI?

Methods and Results are the lowest-risk targets — both are largely mechanical translations of the protocol and output tables into prose. Introduction and Discussion carry more interpretive weight and should be drafted with tighter prompts, grounded in specific references, and reviewed line by line.

How should the Discussion section be handled?

The Discussion is where interpretive overreach and overstated conclusions appear most often. Draft it from a structured outline that states each point you want to make, the reference supporting it, and the hedging language to use. Expect to rewrite AI-generated Discussion text more heavily than any other section.

How do I keep AI from inflating results language?

Instruct the model to use the verbs in the source. Ban a specific list of overclaims (“demonstrates,” “proves,” “superior,” “breakthrough”) unless they appear in the original paper. On review, compare each results sentence with its source and check that no hedging has been quietly removed.

Is AI-drafted text acceptable to journals?

Most journals now permit AI-assisted drafting if it is disclosed and if humans are listed as authors. Check the specific journal’s policy — many require a statement describing how AI was used. AI is not an author; the humans who verified and approved the text are.

• The manuscript meets the target journal’s author guidelines (word count, structure, reference format)
• Author review and input has been obtained on interpretation and conclusions
• All [VERIFY] and [REF NEEDED] flags have been resolved
