Who should choose BeforeTomorrow?
Teams needing investor-grade pitch decks, research-heavy conference presentations, strategy consulting deliverables, or any presentation where content depth, unique design, and professional copy quality justify 10-15 minutes of generation time and $3-20 cost.
Who should choose Gamma?
Teams needing quick visual decks from brief prompts — internal updates, simple reports, or presentations where speed matters more than research depth and design uniqueness. Gamma generates in seconds at lower cost.
How does content depth compare?
BeforeTomorrow deploys specialized agents for each presentation aspect: a Research Agent gathering domain intelligence, a Storyteller planning narrative via Tree-of-Thoughts (8 structures), a Copy Director writing 4,000+ word professional copy, and a Fact Checker verifying claims against tier-1 sources. A 20-slide deck produces 8,000-12,000 words of researched content.
Gamma generates slides from a single AI model in one pass. Content is suitable for quick visual communication but lacks domain research, narrative sophistication, and verified accuracy. Typical output: 1,500-3,000 words of general-purpose text without citations or verification.
