Why a 4-way comparison matters in 2026
Tome shut down — your migration target affects 3 other choices
If you were considering Tome, you now need to pick a migration target. That decision interacts with how Gamma, Beautiful.ai, and Plus AI compare on the same dimensions.
Plus AI lives in PowerPoint; Gamma lives in browser
These are fundamentally different products. Comparing them on AI generation alone misses the workflow question that drives 80% of churn.
Beautiful.ai is design-first, not generation-first
It locks every slide to a smart-template grid. Great for brand consistency, awkward when you need fast iteration on a pitch.
Free tier limits vary widely
Gamma: 400 lifetime credits. Beautiful.ai: 14-day trial. Plus AI: 7 deck generations. Pick by what you can actually try before paying.

When to pick each tool instead of SlideGMM
Frequently asked questions
There isn't one — pick by use case. Web storytelling: Gamma. PowerPoint export: SlideGMM or Plus AI. Brand-consistent corporate decks: Beautiful.ai. Tome is no longer a viable option (sunset April 2025).
Yes. Tome sunset its presentation product on April 30, 2025 and pivoted the company to sales automation (Lightfield). Existing decks viewable but no new presentation creation.
No. Plus AI is a third-party PowerPoint add-in. Microsoft Copilot is bundled with M365 Pro. Plus AI predates Copilot and has stronger AI generation; Copilot is cheaper if you already pay for M365 Pro.
Gamma's 400 lifetime credits is the most flexible. SlideGMM's free tier is the only one that includes PowerPoint export with no watermark. Beautiful.ai's 14-day trial caps you on calendar time, not features.
SlideGMM is the cheapest standalone ($4.99/mo) with source-to-slides (PDF/URL/document parsing) and editable PowerPoint export. Best for founders + researchers whose decks start from external sources rather than blank prompts.
Not really. Each tool uses its own format. Exporting from one and importing into another loses substantial quality. Realistic answer: commit to a tool for 6 months. Try free tiers of 2 before committing.
