Questions & Answers

As answered by people managing ExtendsClass JSON Generator and LaunchDeck.Me.

What makes your product unique?

LaunchDeck.Me's answer:

  • Purpose-built for fundraising decks, not generic slides — narrative, structure, and layouts tuned for investor storytelling.
  • Speed: go from a short brief to a full deck in minutes, not a multi-hour manual build.
  • Large template library (50+) plus layout archetypes the AI fills per slide.
  • Bring your own AI: works with multiple providers (e.g. OpenAI, Gemini, Ollama) and your own API keys when configured that way.
  • Editable outputs: live editing, speaker notes, and export to PDF and PPTX (real decks, not only flat images).
  • Optional web research to ground content in fresher context when you enable it.
  • Open-source core (per your public positioning) for teams that want transparency and control over how presentations are generated.

Why should a person choose your product over its competitors?

LaunchDeck.Me's answer:

  • Faster path to a complete pitch narrative — less time writing and restructuring slides from scratch in a general-purpose editor.
  • Investor-oriented templates and slide patterns vs. starting from blank or generic business decks.
  • Flexibility on AI — use the model stack you prefer (cloud or self-hosted) instead of being locked to one vendor’s assistant.
  • Practical deliverables — PPTX for last-minute edits and PDF for sharing; no design tool learning curve required.
  • Generous way to try it — free tier with 3 decks per month and no card up front (as marketed on-site).

How would you describe the primary audience of your product?

LaunchDeck.Me's answer:

Founders and small teams raising money or explaining traction — especially pre-seed and seed — plus operators who need a credible deck quickly (sales, partnerships, accelerators, demo days). Secondary audience: anyone who wants professional presentations without spending days on layout and copy.

What's the story behind your product?

LaunchDeck.Me's answer:

LaunchDeck exists because building a convincing pitch deck is slow, repetitive work — merging narrative, data, and design — while fundraising timelines are not. The product was built to compress that workflow: describe the company once, let AI propose structure and copy, apply proven presentation patterns, and ship something you can edit and export the same day.

Which are the primary technologies used for building your product?

LaunchDeck.Me's answer:

Next.js, React, TypeScript, Tailwind CSS, Radix UI primitives. Backend: FastAPI (Python) API server (monorepo under servers/). Other notable libs/tools: Redux Toolkit, TipTap, Zod, Puppeteer/related tooling where exports or rendering need headless browser support — plus integrations with LLM providers (OpenAI, Google Gemini, Ollama, etc.) depending on deployment configuration.

Who are some of the biggest customers of your product?

LaunchDeck.Me's answer:

  • Customer names are not publicly disclosed; the product primarily serves individual founders and small teams on a self-serve basis.
