Quick Answer
Gamma is the current product choice. Tome’s co-founder announced in March 2025 that the company was sunsetting its slides product and becoming Lightfield; in August 2025 he described Tome as shut down. A 2026 “Gamma versus Tome” buying comparison is therefore misleading.
Use this page as a migration and replacement guide: evaluate Gamma for live presentation, document, website, sharing, export, and API workflows. If you have old Tome source material, rebuild from the original outline and assets rather than assuming an old Tome workspace or export path remains available.
Current Status
| Question | Gamma | Tome Slides |
|---|---|---|
| Live presentation product | Yes | No; founders announced the sunset and company pivot |
| Create from prompt or outline | Available | Historical capability only |
| Export | PDF, PPTX, PNG, and Google Slides paths are documented | Do not plan a new workflow around it |
| Live sharing | Gamma link and publishing workflows | Historical capability only |
| API | Gamma documents an asynchronous generation and export API on eligible plans | No current presentation API to evaluate |
| Buying decision | Test the current plan | Choose a current alternative |
This status changes the search intent. The useful question is not “which is better?” but “does Gamma replace the part of Tome that mattered to my team?”
When Gamma Is a Good Replacement
Gamma is a strong candidate when the team needs:
- a fast first draft from a prompt, outline, or imported document;
- a card-based presentation or document that can be shared as a link;
- export to PowerPoint, PDF, or images;
- presentation, document, webpage, and social formats in one workspace;
- brand themes, analytics, advanced sharing, or API generation on an eligible plan.
Gamma’s official export guidance warns that exported PowerPoint or PDF files can differ from the editing view. Always inspect the actual export in the software used by the recipient.
When to Choose Another Tool
Gamma may not be the right replacement when the workflow depends on pixel-exact PowerPoint masters, complex animations, offline-only editing, deep spreadsheet links, or a corporate template that cannot tolerate layout changes. In those cases, test native PowerPoint, Google Slides, Keynote, or another governed presentation system.
The Gamma alternatives guide provides a broader shortlist. For a current plan decision, use the Gamma pricing guide instead of copying credit or price details into this lifecycle page.
A Safe Tome-to-Gamma Migration
1. Recover source truth
Collect the original outline, notes, charts, images, citations, speaker notes, and brand files. Treat a screenshot or old export as a visual reference, not the only editable source.
2. Separate facts from layout
Verify dates, metrics, customer claims, and citations before importing. A visually polished legacy deck can still contain stale business facts.
3. Build one representative deck
Use a real 10–15 slide presentation. Start from the outline or import a document, apply the theme, then edit the story and evidence manually.
4. Test every delivery format
Compare Gamma Present Mode, PDF, PPTX, and Google Slides import if those formats matter. Look for overflow, font substitution, image crop, chart movement, speaker-note loss, and accessibility problems.
5. Decide with measurable criteria
Record draft time, manual repair time, export defects, reviewer comments, brand deviations, and accessibility issues. Choose the workflow with the lowest accepted-delivery cost, not the fastest first draft.
Narrative Quality Still Needs a Human
AI can propose a structure, but it does not know which evidence will persuade a specific audience. A useful business deck still needs:
- one decision or message per section;
- evidence attached to the claim it supports;
- explicit uncertainty and source dates;
- charts that answer a question rather than decorate a slide;
- a final ask that matches the audience’s authority.

FAQ
Is Tome still an AI presentation tool?
No. Tome’s founders announced the slides sunset and a pivot to Lightfield in 2025. Do not start a new presentation workflow on the assumption that the former Tome Slides product is available.
Is Gamma the official successor to Tome?
No. Gamma is a separate company and product. It is a practical replacement candidate because it supports AI-assisted presentations and exports, not because it inherited Tome.
Can Gamma export to PowerPoint?
Yes. Gamma documents PPTX export and a Google Slides path through PPTX. Review the exported file because layout, font, chart, or scaling differences can occur.
Does Gamma have a free plan?
Gamma currently lists a Free plan with starter credits and basic creation/import/export features. Credits, limits, branding, and paid-plan features can change; verify the live pricing page.
