DeckGrade - AI Pitch Deck Structure Grader That Thinks Like a VC Partner
You spent three weeks on your pitch deck and the only feedback you got was 'needs more traction' from a friend who has never raised money. DeckGrade analyzes your deck slide by slide against proven VC narrative frameworks and tells you exactly which slides are killing your chances before you send the cold email.

What is it?
Founders raising pre-seed and seed rounds in April 2026 have access to more deck templates than ever but zero structured feedback on whether their specific narrative is compelling to investors. DeckGrade accepts a PDF deck upload, extracts text and slide structure using pdf-parse, and runs each slide through Claude with a VC evaluation rubric covering problem clarity, market sizing, traction signal, and ask framing. It returns a scored report per slide with specific rewrite suggestions. This is not a generic AI writing tool — it is a structured evaluation framework built on actual VC feedback patterns. Buildable right now because Claude handles multi-section document analysis reliably, pdf-parse is stable, and the target audience actively pays for pitch coaching at $500-$2000 per session.
Why now?
The April 2026 vibe-coding fundraising wave has more founders pitching investors than ever while VC partner time per deck has dropped below 3 minutes — founders are desperate for structured pre-submission feedback and willing to pay for it.
- ▸PDF deck upload with slide-by-slide text extraction using pdf-parse.
- ▸Claude evaluation of each slide against a 10-point VC rubric covering narrative, market, traction, and ask.
- ▸Scored report with specific rewrite suggestions per slide, not generic advice.
- ▸One-click Stripe payment to unlock full report after free preview of first three slides.
Target Audience
Pre-seed and seed stage founders preparing pitch decks, roughly 500k+ active fundraising rounds globally per year.
Example Use Case
Jordan uploads her 14-slide pre-seed deck, gets a scored report in 90 seconds showing her market size slide scores 4/10 because it conflates TAM and SAM, rewrites it following the suggestion, and emails the updated deck to investors the same day.
User Stories
- ▸As a pre-seed founder, I want my pitch deck graded slide by slide against a VC rubric, so that I fix weak slides before sending to investors.
- ▸As a first-time founder, I want specific rewrite suggestions not generic tips, so that I know exactly what to change on my market size slide.
- ▸As a solo founder, I want a scored deck report I can share with my co-founder, so that we align on which slides to prioritize in our next revision.
Acceptance Criteria
PDF Upload: done when a 20-slide PDF uploads, extracts text, and triggers analysis within 30 seconds. Scoring: done when every slide receives a numeric score 1-10 and a one-paragraph suggestion. Payment Gate: done when Stripe checkout processes and slides 4+ unlock immediately on success. Report Delivery: done when Resend email with report link fires within 60 seconds of analysis completion.

What's the competition?
Competition Level
Medium
Similar Products
Slidebean (design-focused, no narrative scoring), Tome (deck builder, no evaluation), Pitch.com (collaboration tool, no VC rubric feedback).
Competitive Advantage
Slidebean grades design, Canva AI fixes formatting — neither evaluates narrative structure against a VC investment rubric with slide-level scored feedback.
Regulatory Risks
Low regulatory risk. Deck content may include confidential business data — document that files are not used for model training and offer deletion.
What's the roadmap?

How do you build it?
Tech Stack
Next.js, Claude API, pdf-parse, Supabase, Stripe, Resend — build with Lovable for UI, Cursor for PDF parsing and Claude prompt logic, v0 for report components.
Suggested Frameworks
LangChain, pdf-parse, Claude API claude-3-5-sonnet
Time to Ship
1 week
Required Skills
Claude API prompt engineering, pdf-parse text extraction, Next.js file upload handling.
Resources
Claude API docs, pdf-parse npm docs, Stripe one-time payment docs, Supabase storage docs.
MVP Scope
app/upload page, api/analyze.ts (pdf-parse plus Claude call), api/stripe/checkout.ts, app/report/[id] page (scored slide breakdown), lib/rubric.ts (VC evaluation prompts), supabase storage for PDF files, supabase table for analysis results.
Core User Journey
Upload PDF deck -> free preview of first 3 slides scored -> pay $19 to unlock full report -> read slide-by-slide rewrites -> share report with co-founder.
Architecture Pattern
User uploads PDF -> Supabase Storage -> api/analyze.ts extracts text via pdf-parse -> Claude API evaluates per slide against rubric -> scores stored in Supabase -> report page renders -> Stripe gates full report behind payment.
Data Model
User has many Analyses. Analysis has one PDF file in Storage and many SlideScores. SlideScore has slideIndex, score, category, and suggestion fields.
Integration Points
Claude API for VC rubric evaluation, pdf-parse for text extraction, Supabase Storage for PDF files, Supabase Postgres for analysis results, Stripe for one-time payment, Resend for report delivery email.
V1 Scope Boundaries
V1 excludes: visual slide design scoring, investor CRM integration, team collaboration, mobile app, custom rubric builder.
Success Definition
A founder the founder has never met uploads a deck, pays $19, reads the report, rewrites a slide based on the feedback, and shares the tool in a Slack community.
Challenges
Standing out from generic AI writing tools requires a hyper-specific rubric that actually mirrors VC thinking — the prompt engineering is the product moat, not the UI.
Avoid These Pitfalls
Do not build a deck editor in V1 — grade first, edit later. Do not try to parse visual slide layouts in V1, text extraction is enough for narrative evaluation. Finding first 10 paying founders takes 3x longer than building the analyzer.
Security Requirements
Supabase Auth with Google OAuth, RLS on all user data, PDFs stored in private Supabase bucket with signed URLs, no deck content used for model training documented in privacy policy, GDPR deletion endpoint.
Infrastructure Plan
Vercel for Next.js, Supabase for Postgres and file storage, Sentry for errors, GitHub Actions for CI, no separate backend needed.
Performance Targets
50 DAU at launch, 100 analyses/day. PDF parse and Claude call under 30 seconds per deck. Report page load under 2s. No caching needed at launch scale.

How to build it, step by step
1. Run npx create-next-app deckgrade and install pdf-parse, @supabase/supabase-js, stripe, resend, anthropic. 2. Create Supabase storage bucket for PDFs and analyses table with slide_scores JSONB column. 3. Build app/upload page with drag-and-drop PDF upload that posts to Supabase Storage via signed URL. 4. Build api/analyze.ts that downloads PDF from storage, runs pdf-parse to extract text by page, and batches pages into Claude prompt. 5. Write lib/rubric.ts with 10-point VC evaluation prompt template covering problem, market, traction, team, ask. 6. Build Claude call that returns structured JSON with score and suggestion per slide. 7. Build app/report/[id] page that renders slide scores as cards with color-coded ratings using v0 components. 8. Add Stripe one-time payment checkout that unlocks slides 4 onward after free preview of first 3. 9. Send analysis complete email via Resend with link to full report. 10. Deploy to Vercel, add Sentry, post in r/startups with free analysis offer.
