Gamma Studio

Decks written in your voice, built automatically in Gamma.

You describe what you need. A built-in LLM writes every slide in your brand voice using your uploaded voice samples and brand kit. The finished copy is pushed straight into Gamma, which builds the layout. A polished deck in minutes instead of days.

This is a self-hosted app. You run your own copy with your own keys and your own Supabase project. Nobody shares an instance — your brand, your data, your account.

What it does

1. Brand Kit — upload your logo, colors, fonts, brand voice transcripts, and reference files once.
2. Studio — type a brief ("Client proposal for a social media agency"), attach any source files, pick a Gamma template.
3. The authoring layer (Claude) writes the full deck copy in your voice.
4. The copy is sent to Gamma, which builds the deck. You get a link.

Stack

• Next.js 14 (App Router) + TypeScript + Tailwind
• Supabase (auth, Postgres, storage)
• Anthropic Claude (slide copy authoring)
• Gamma REST API (deck building)

Quickstart

git clone <your-fork-url> gamma-studio
cd gamma-studio

You need a Supabase project, a Gamma API key, and an Anthropic API key. The full walkthrough is in SETUP_GUIDE.md (and the branded SETUP-GUIDE.pdf).
