Tome vs SlideGMM 2026: Migration Guide + 5 Alternatives Ranked

Disclosure first: we make SlideGMM. We ran paid Tome subscriptions in parallel with our own product through 2024 and into 2025 — until Tome sunset its presentation product on April 30, 2025 and pivoted the company to sales automation. This post is the migration guide we wish existed when the announcement landed.

If you're a Tome user trying to figure out what to do next, you're in the right place. We'll cover what happened, what to do with your existing decks, and an honest comparison of the three or four tools you should actually consider migrating to.

What actually happened to Tome

In March 2025 Tome announced it was sunsetting its AI presentation product and rebranding the company toward sales automation — research, meeting preparation, account intelligence. The presentation features stopped accepting new content on April 30, 2025. Existing users can still view decks, but the product is no longer maintained.

The pivot wasn't a surprise to people watching the AI presentation category closely. Tome had raised heavy ($81M cumulative across rounds) and the AI presentation space was getting crowded fast: Gamma, Beautiful.ai, Decktopus, Plus AI, and (yes) SlideGMM all chasing the same surface area. Sales automation has higher revenue per seat and longer customer retention. The math was clear.

What this means for you, the user with a half-built deck on tome.app: nothing breaks tomorrow, but the product won't get better, integrations will atrophy, and at some point support will end. Migrate your active decks. Archive the rest.

What to do with your existing Tome decks

Three paths, in order of preference:

1. Export to PDF, archive

Best for decks you're done with — fundraising decks from a closed round, conference talks already given, archived board updates. Export each to PDF, save to your team drive, move on. PDF is the most durable format Tome supports.

2. Rebuild in a new tool

Best for active decks you'll edit again. Plan ~30–60 minutes per deck for content rebuild — Tome's free-form layout doesn't always map cleanly to other tools' slide grids. The good news: most of your text content can be pasted directly. The bad news: image positioning and animation timings won't carry over.

3. Live with the link until it stops working

Worst, but realistic for low-priority decks (a one-off webinar deck nobody will reuse). Just don't be surprised when the share link breaks in 6–12 months.

Where to migrate: honest comparison of 5 alternatives

We tested Tome alongside Gamma, Beautiful.ai, Plus AI, Decktopus, and SlideGMM throughout 2024–2025. Here's where each lands as a Tome replacement.

If you came to Tome for storytelling: → Gamma

Gamma is the closest spiritual replacement for Tome — narrative-first, scroll-style decks designed to live on the web. The migration friction is lowest here because both tools have similar "deck = doc, scroll to read" mental models. Gamma's weakness is the same as Tome's: PowerPoint export flattens slides to images. If your deck is meant for the browser, this doesn't matter. If you'll ever export to .pptx, it does.

If you need PowerPoint export: → SlideGMM or Plus AI

Tome's .pptx export was a known weak spot — the same way Gamma's is. Both tools render decks as web objects first and try to translate to PowerPoint second. The result: flattened layouts, missing animations, substituted fonts, and editing pain.

Two tools were specifically built around clean PowerPoint round-trip:

• SlideGMM outputs editable .pptx with preserved text layers, real text boxes (not images), and font-fallback logic. Free tier includes .pptx export. Paid tier $4.99/mo. Disclosure: this is our product. Honest take: it's the most affordable option in the category and our PowerPoint export is the differentiator we lead with.
• Plus AI is built on top of Google Slides and PowerPoint directly, so "export" isn't really export — your deck is already a native .pptx or Slides file. If you're already deep in Google Workspace or Microsoft 365, Plus AI feels closer to home.

If you came to Tome for mobile editing: → Gamma (still)

Tome's mobile editor was the best in category through 2024. Gamma's caught up by 2026; Beautiful.ai's mobile is limited; SlideGMM's mobile is currently presenting-only (we're working on it, but it's not closing this gap soon). For mobile-first deck builders, Gamma is the migration.

If you want the cheapest option: → Decktopus or SlideGMM

Decktopus's $6/mo Pro tier is the cheapest standalone AI presentation tool in the category. SlideGMM's $4.99/mo Plus tier is cheaper still and includes more features at that tier (PowerPoint export, multilingual generation). Decktopus's strength is its Q&A-coaching feature for live presenting; if that's a priority, evaluate it first. Otherwise SlideGMM wins on price + feature density.

If you came to Tome for brand-consistent design: → Beautiful.ai

Tome's smart-style features and Beautiful.ai's design automation overlap meaningfully. Beautiful.ai's "smart slides" approach enforces brand kits and design rules in a way that's stronger than Gamma or SlideGMM. The tradeoff: less creative flexibility. If your team's pain is "our decks look inconsistent across reps," Beautiful.ai is the migration. If your team is small and wants flexibility, look elsewhere.

A migration checklist (pragmatic, not exhaustive)

Print this, work through it once per active deck:

1. Export the Tome deck to PDF (File → Export → PDF). This is your safety net.
2. Pick the destination tool based on the section above. Don't agonize — most decisions are reversible if you export-rebuild-reexport.
3. Generate a fresh deck in the new tool with your topic. Use the AI generation as a starting frame, not a 1:1 rebuild — the new tool's structure won't match Tome's.
4. Copy text content over manually, slide by slide. Most AI tools have a "regenerate this slide" button — useful for stuck moments.
5. Re-add custom images and brand assets. None of these carry over from Tome.
6. Test export to .pptx and PDF in the destination tool — verify what you'll actually deliver to clients/investors looks right.
7. Update your share links wherever the old Tome link was embedded (email signatures, sales decks, internal wikis).

Plan ~30–60 minutes per active deck. If you have 5–10 active decks, this is a half-day project, not a week-long migration.

What the Tome shutdown signals about the AI presentation category

A few honest observations from someone who runs one of the alternatives:

The category is consolidating. Tome was well-funded, well-designed, and still couldn't make presentation tools work as a standalone business. That tells you the market is competitive and margins are thin. The survivors are going to be tools that own a clear niche (Beautiful.ai = brand consistency; SlideGMM = PowerPoint export + multilingual; Gamma = storytelling) rather than horizontal "AI presentations" plays.

PowerPoint export quality is the underrated dividing line. Tome and Gamma both ran into the same wall: their decks live great on the web, but export to .pptx is where most business users actually need them. The tools that solved this (Plus AI, SlideGMM, Beautiful.ai to a lesser extent) are positioned better for the long term.

Mobile is real, but a hard moat to maintain. Tome's mobile editor was excellent. It's also expensive to maintain across product surface area. Watch which tools keep investing here.

Where SlideGMM lands in this picture

Honest take: we built SlideGMM around the gap that Tome and Gamma left open — clean PowerPoint export, URL-to-presentation conversion, and multilingual generation across 10 locales. We're cheaper than the rest of the category ($4.99/mo Plus, $49.99/yr) because that's where we want to compete; we're not trying to win on storytelling-narrative decks (Gamma's home turf) or design-consistency-at-scale (Beautiful.ai's home turf).

If you came to Tome for any of: PowerPoint-bound decks, importing PDFs/URLs into a deck, generating decks in Turkish/Spanish/German/Japanese/etc., or just paying less — give SlideGMM a try free. If you came to Tome for any of: web-only narrative decks, mobile editing, sleek brand-kit enforcement — go to Gamma, Plus AI, or Beautiful.ai. We'd rather you pick the right tool than land here and feel like the migration was sideways.

The shutdown is unfortunate. Tome built something good. The pivot is rational. Migration is annoying but doable. And the AI presentation space is, for the first time in a while, genuinely settling into clear positioning categories — which is good for users.
