Grant writing is one of the most competitive and resource-intensive processes organizations face. With AI tools flooding the market, many promise to reduce workloads and increase success rates. But do they actually deliver?
At Cogrant, we tested 21 of the most popular AI tools used (or marketed) for grant writing. We examined each against real-world tasks: grant discovery, proposal drafting, research, editing, compliance, and submission. Our mission was to identify which tools save time, which fall short, and ultimately, which one is the best in the world.
Below you’ll find our full results (kept intact), plus expanded context: how we tested, what “good” looks like for grant writing, practical workflows, prompt recipes, risk and compliance checklists, and a buyer’s guide for teams deciding what to adopt next.

Why Cogrant Wins + Next Steps
1) How We Tested (and Why It Matters)
Real proposals, real constraints. Instead of synthetic prompts, we used live or recently awarded calls and realistic organizational profiles (nonprofits, universities, SMEs, municipalities) to see how tools behave when the stakes are high.
Representative tasks across the grant lifecycle:
Discovery: finding relevant opportunities that match eligibility, geography, and thematic focus.
Qualification: scoring fit, extracting requirements, and building a go/no-go rationale.
Drafting: problem statements, theory of change, methodology, work plan, timeline, budget narrative.
Evidence & citations: finding policy references, authoritative statistics, and prior results.
Compliance: word counts, sections, formatting, attachments, eligibility, and required forms.
Editing & collaboration: version control, reviewer workflows, and style consistency.
Submission readiness: completeness checks, cover letters, bios, and appendices.
How we evaluated:
We scored each tool qualitatively across eight dimensions (see next section), captured time saved or lost, noted hallucinations, and recorded where human intervention remained essential.
2) The Grant-Writing Capability Model (8 Dimensions)
Use this as your mental checklist when evaluating any AI tool for grants:
Opportunity Alignment – Can it surface relevant calls and extract eligibility, geography, and thematic fit?
Drafting Quality – Structure, clarity, cohesion, and specificity to funder language.
Evidence & Citations – Ability to find, cite, and summarize credible sources.
Compliance & Controls – Word limits, section mapping, forms, attachments, and formatting.
Collaboration – Role-based workflows, comments, tasks, and version history.
Security & Governance – GDPR alignment, data residency, model privacy guarantees.
Integrations – Docs/Sheets, project tools, reference managers, and submission portals.
Scalability – Handles multiple proposals, complex consortia, and multi-country contexts.
Most general tools score well on #2 (surface-level drafting) but underperform on #1, #3, and #4—precisely where grants are won or lost.

(This section preserves your original data and structure. We’ve added formatting only for readability.)
General AI Assistants
ChatGPT (OpenAI)
Overview
ChatGPT is the most widely known AI assistant, used globally for content creation, Q&A, and drafting. Many grant seekers try it because of its accessibility and low cost.
Strengths
It generates text quickly, can adapt tone, and works well for brainstorming or rewriting. With strong prompts, it can produce usable outlines and initial drafts.
Weaknesses
ChatGPT has no awareness of funder requirements. It often produces generic, superficial content and is prone to “hallucinations” (fabricating facts or references). It lacks compliance support, collaboration tools, and expert oversight. For grants, this makes it risky and unreliable.

4) Why General-Purpose AI Falls Short for Grants
Grant proposals aren’t marketing pages. They are structured arguments backed by evidence, budgets, work plans, and strict compliance. General AI can produce nice sentences but typically fails at:
Funder-specific language. Each call has its own taxonomy, keywords, and evaluation rubric.
Traceable evidence. Reviewers expect real citations, not synthesized facts.
Format discipline. Word/character counts, page limits, templates, and required forms.
Cross-section coherence. The needs statement must align with objectives, methods, team capacity, indicators, and budget narrative.
Without these, proposals sound plausible but don’t score.
5) Practical Workflows: From Discovery to Submission
Here’s a blueprint you can adopt, even if you stick with several tools from the list:
A) Discovery & Qualification
Start with a dedicated grant database (regional + thematic).
Extract eligibility, budget caps, geography, match funding, TRLs (if applicable), deadlines, mandatory partners.
Produce a 1-page Go/No-Go brief with: Fit %, key risks, and required assets (CVs, letters, prior results).
B) Proposal Architecture
Build a section map mirroring the funder’s outline.
For each section: purpose, word limit, required sub-elements, and evidence notes.
Define logical framework / ToC: problem → outcomes → outputs → activities → indicators → assumptions.
C) Drafting & Evidence
Use a general model only for outlines or first-pass narrative.
Pull citations via a researcher (e.g., Perplexity/Scite) and save references in a manager (Zotero, etc.).
Replace generic claims with country- or region-specific statistics and policies.
D) Compliance & Red Team Review
Run word-count and formatting checks.
Cross-check consistency: objectives ↔ indicators; activities ↔ budget lines; roles ↔ CVs.
Conduct a hallucination audit: verify every fact with a source or remove it.
E) Final Assembly & Submission
Convert to funder templates, include annexes (Gantt, risk matrix, ethics, data management).
Conduct a cold read by someone not involved in drafting.
Submit early to avoid portal failures.
6) Prompt Recipes You Can Copy Today
Section Skeleton Builder
“You are a grant proposal architect. Create a section-by-section outline that mirrors the following call’s structure (paste headings here). For each section, list required elements, target word counts, and reviewer expectations in bullet points.”
Evidence Gap Finder
“Scan the following draft (paste text) and list any claims that need citations. For each, suggest the specific data type (e.g., Eurostat unemployment 2023 regional rate), and relevant credible sources.”
Logic Model Consistency Check
“Given objectives A/B/C, indicators X/Y/Z, and activities 1-6, identify any misalignments or missing causal links. Propose revisions so each objective has at least one measurable indicator and related activities.”
Budget Narrative Tightener
“Rewrite this budget narrative (paste) to clearly justify each cost against the methodology and timeline. Reduce fluff and ensure language matches the funder’s cost eligibility guidelines.”
Reviewer Lens Rewrite
“Rewrite this ‘Needs’ paragraph for a reviewer who prioritizes measurable outcomes and cost-effectiveness. Keep it under 180 words, use plain language, and anchor with two verifiable statistics (placeholders allowed).”
7) Compliance & Risk: What Reviewers Actually Look For
Eligibility non-negotiables: legal status, geography, prior track record, match funding, ethical approvals.
Clarity & specificity: numerical targets, baseline data, who-does-what-by-when.
Feasibility: budget realism, team capacity, risk mitigation, and contingency plans.
Evaluation plan: indicators, data collection, sampling, disaggregation, and learning loops.
Sustainability: what happens after the grant; policy uptake or revenue pathways.
Ethics & data protection: GDPR, consent, data minimization, DPIAs if sensitive data is processed.
Formatting discipline: follow templates, font sizes, page limits, file naming, and annexes.
Red Flags to eradicate: inflated claims, missing citations, generic impacts, budget-activity mismatch, last-minute portal uploads, and “one size fits all” prose.

9) FAQ: Cost, Accuracy, Data Security
Q: Can general AI fully write a winning grant?
A: Not reliably. It accelerates drafting but still needs expert oversight, verified evidence, and compliance checks.
Q: Where does AI save the most time?
A: Early structuring, first-pass drafting, evidence triage, and consistency checks across large documents.
Q: How do we protect sensitive data?
A: Use tools that honor GDPR, offer data residency options, and allow no-training modes so your data isn’t used to train public models.
Q: What about global (non-U.S.) funding?
A: Choose platforms with EU + international coverage, aligned to EU AI and data protection standards.
