AI form filling that keeps your layout 100% intact

SnapFill automates your most tedious paperwork:filling forms from research grants to legal docs. Manual entry is slow, and most AI tools break document layouts. SnapFill solves this by building a structured Knowledge Hub from your own files to fill new forms with deep context. Crucially, our engine guarantees Perfect Formatting: your output PDF or Word doc looks identical to the original, with tables, fonts, and styles perfectly preserved.







Hey Product Hunt! 👋
I’m XiangLei, CEO of SnapFill.
I built SnapFill because I hit a breaking point. Last year, while applying for a government grant for our company, I spent 6 hours manually copying numbers from our financial model into a rigid DOCX form.
I tried asking GPT to do it, but the results were messy: the numbers were mostly right, but the table borders were destroyed, the fonts were wrong, and the document was unusable.
The problem wasn't the "intelligence"—it was the "formatting" and the "context."
So, we built SnapFill to solve exactly that. It’s an AI agent designed for the boring (but critical) paperwork that runs the world.
Here is how it works:
🧠 Build Your Brain: Upload your core docs (pitch decks, past filings, spreadsheets). We use a Tree-RAG engine to structure this into a "Knowledge Hub."
📝 Upload Any Form: Drag in that complex PDF or Word doc you’ve been dreading.
✨ Perfect Fill: The AI fills it out using your knowledge base. Crucially, it preserves 100% of the original layout. Tables, checkboxes, and fonts stay exactly where they should be.
Who is this for?
- Founders: For grants (SBIR/R01), accelerators (YC), and due diligence questionnaires.
- Legal Pros: For discovery requests and standardized contracts.
- Ops Teams: For vendor onboarding and security questionnaires.
- And anyone who is tired of tedious form filling :)
We are launching today with a Free Tier so you can try it out.

@lightninglx Congrats. What inspired you to build SnapFill, especially the focus on keeping form layouts 100% intact while using AI to fill data?
Was there a story or specific user problem that made you realise this was a big pain point?

Love how it builds a Knowledge Hub. It’s like having a personal assistant who remembers every past file.
@sshreeey Exactly! It's like a personal assistant who never sleeps and has a photographic memory for all your filings. Thanks for the support!
Finally, an AI that doesn't mess up my tables. Filled a 20-page legal doc in minutes.
Saved us from a weekend of manual data entry for our latest project filing.
