Felo Slides vs Gamma vs Tome: Which AI Slides Tool Is Right for You? (2025 Honest Comparison)
Felo Slides vs Gamma vs Tome — we tested all three AI slides tools head-to-head across design, features, pricing, and multilingual support. Here's who wins what.
You've got a deck to build. The deadline is tomorrow. And you just discovered that three different AI slides tools all promise to finish it in minutes.
Felo Slides. Gamma. Tome.
They sound similar. They market to the same frustrated professionals scrolling Twitter at midnight. But under the hood, they're very different products — and picking the wrong one means wasted hours fighting a tool that wasn't built for your workflow.
We've spent weeks testing all three across real projects: investor pitches, client reports, internal all-hands, webinar decks, and multilingual presentations. This is the no-BS breakdown.

Quick Introductions: Meet the Contenders
Felo Slides
Felo Slides is an AI-powered presentation generator built for people who think in sources, not blank canvases. You feed it a URL, a PDF, a YouTube link, or a block of text — and it produces a structured, designed deck in seconds. It's the newest entrant in this comparison, and it leads with two things: input flexibility and multilingual depth.
Felo Slides is part of the broader Felo AI suite (search, translate, agent), which matters if you work across languages or need to pull content from research before you present.
Gamma
Gamma burst onto the scene in 2023 and quickly became the "design-first" AI slides tool. Its strength is visual polish — the generated decks look like a mid-tier design agency touched them up. Gamma uses a card-based system rather than traditional slides, which gives it a modern, web-native feel. It's popular with startups, educators, and anyone who cares deeply about aesthetics.
Tome
Tome positioned itself as an AI storytelling tool. The pitch: your ideas deserve more than bullet points. It leans into narrative structure, cinematic layouts, and a somewhat artsy design language. Tome works well for pitch decks and portfolio-style presentations, but it has narrower input options and fewer export formats than the other two.

Input Sources: Where Does Your Content Come From?
This is where the three tools diverge most sharply, and it's the single most underrated factor in choosing an AI slides tool.
Felo Slides: The Swiss Army Knife
Felo Slides accepts four input types out of the box:
- URL — Paste a blog post, news article, or research page. Felo fetches and structures it.
- PDF — Upload a whitepaper, report, or academic paper. Felo extracts the key points.
- YouTube — Drop a video link. Felo pulls the transcript and builds a deck from it.
- Plain text — Type or paste whatever you want.
This matters more than you'd think. Most presentation workflows start with existing content — a report someone sent you, a competitor's landing page, a conference talk you watched. Felo Slides eliminates the copy-paste-restructure cycle that eats 30 minutes before you even open a slide editor.
Gamma: Prompt-Driven
Gamma's primary input is a text prompt. You describe what you want, and it generates. You can also paste text or upload basic files, but there's no URL fetching or YouTube integration.
For pure "idea to deck" speed, Gamma's prompt interface is smooth. The AI interprets your intent well and structures content logically. But if your source material lives on the web or in a PDF, you'll need to extract and paste it manually first.
Tome: Prompt-Driven, Narrower
Tome works similarly to Gamma — text prompt in, story-driven deck out. It doesn't support URL input, PDF parsing, or YouTube extraction. You're working from your own words or pasted content.
Verdict: If you regularly build decks from external sources (articles, reports, videos), Felo Slides is the only tool here that handles those natively. Gamma and Tome both require you to bring your own structured text.
Design Quality: Who Makes the Best-Looking Decks?
Let's be honest — this is probably why you clicked on this article.
Gamma: The Design Leader
Gamma's output is genuinely impressive. The layouts feel modern, the typography is tight, and the color palettes don't look like default PowerPoint themes. The card-based format gives presentations a web-page quality that works beautifully for screen-sharing and async viewing.
The downside: that card-based format isn't traditional slides. If your audience expects a 16:9 deck they can flip through, Gamma's format can feel unfamiliar. And since there's no PPTX export, you can't convert it after the fact.
Felo Slides: Clean, Professional, Customizable
Felo Slides prioritizes clarity and structure over artistic flair. The generated decks are clean, well-organized, and immediately editable. The design language is more "consulting deck" than "startup landing page" — which is a feature, not a bug, if your audience is executives or clients who want information density over vibes.
Where Felo pulls ahead is customization. You can adjust templates, swap color schemes, modify fonts, and restructure layouts — all within the editor. Gamma gives you theme-level controls; Felo gives you slide-level control.
Tome: Cinematic but Constrained
Tome's aesthetic is distinctive — moody gradients, full-bleed images, dramatic typography. For the right use case (a founder's story, a product vision deck, a portfolio), it looks stunning.
For everything else? It can feel over-designed. A 20-slide internal status update in Tome's style is like wearing a tuxedo to a standup meeting. The design system also has less flexibility — you're working within preset styles, and deviating from them is frustrating.
Verdict: Gamma wins on raw visual polish for web-native presentations. Felo Slides wins on customization and traditional slide format. Tome wins for niche storytelling use cases but loses versatility.

Template Customization: How Much Control Do You Actually Get?
Felo Slides
Full template control. You get:
- Custom color palettes
- Font selection
- Layout adjustments per slide
- Template saving for reuse across decks
- Brand consistency across team presentations
If you have brand guidelines (and most teams past a certain size do), Felo Slides lets you work within them.
Gamma
Theme-level customization. You can:
- Choose from preset themes
- Adjust accent colors
- Modify some typography settings
- Rearrange card layouts
But you can't deeply customize individual cards the way you'd customize a PowerPoint slide. Gamma's philosophy is "trust the AI's design judgment," which works until it doesn't.
Tome
Preset-driven. You pick a style at generation time, and that's largely your ceiling. Tome intentionally limits customization to maintain its design consistency — which again, is great for storytelling decks and limiting for everything else.
Verdict: Felo Slides is the clear winner for anyone who needs brand-aligned or heavily customized presentations. Gamma is adequate for teams without strict brand requirements. Tome is the most restrictive.
Export Formats: Where Does Your Deck Go After You Build It?
This is the factor most comparison articles skip — and it's the one that bites you at the worst time.
Felo Slides
Exports to:
- PPTX (PowerPoint) — Edit offline, present in any conference room, upload to any platform
- PDF — Universal, print-ready
- Shareable link — Web viewing with analytics
The PPTX export is a big deal. Most corporate environments still run on PowerPoint. Clients send .pptx files. Investors expect .pptx files. Conference AV systems run .pptx files. Being able to generate with AI and export to the universal standard is a practical advantage that matters the moment you step outside the web-native world.
Gamma
Exports to:
- PDF — Static, non-editable
- Shareable link — Web viewing
- Embed — For websites and docs
No PPTX. No PowerPoint. No offline editing. Gamma is a web-first, web-only tool. If your workflow requires handing off a file someone else can edit — good luck.
Tome
Exports to:
- PDF — Static
- Shareable link — Web viewing
Same limitation as Gamma. No PowerPoint export. No offline workflow.
Verdict: If you ever need to present offline, send a file to a client, or work within a corporate PowerPoint workflow, Felo Slides is the only option here that doesn't force you into a web-only ecosystem.
Pricing: What Does This Actually Cost?
Felo Slides
Felo Slides offers a generous free tier that covers most individual use cases. You can generate, customize, and export decks without paying anything upfront. Pro plans are available for teams and power users who need higher volume and advanced features.
The exact pricing details change, so check Felo's pricing page for current numbers — but the key point is: you can start for free and stay free for a long time.
Gamma
Gamma's free tier gives you limited AI credits — enough to generate a handful of decks and see if you like it. After that:
- Plus: $10/user/month (billed annually) — removes watermarks, adds more AI credits
- Pro: $20/user/month (billed annually) — advanced features, priority generation
For a team of 10, that's $100–$200/month. It adds up.
Tome
Tome's free tier is similarly limited. Paid plans:
- Pro: $16/user/month (billed annually)
- Business: Custom pricing
Tome is the most expensive option on a per-user basis, and it offers the fewest input/export features. You're paying primarily for the design aesthetic and storytelling framework.
Verdict: Felo Slides is the most affordable option, especially for individuals and small teams. Gamma is mid-range. Tome is the priciest relative to what you get.

Multilingual Support: Who Else Speaks Your Language?
This is where Felo Slides laps the competition — and it's not close.
Felo Slides
Supports 20+ languages with deep, native-quality output. You can:
- Generate decks in Japanese, Korean, Chinese, Spanish, French, German, Portuguese, and many more
- Input source content in one language and generate the deck in another
- Leverage Felo's built-in translation engine (part of the broader Felo AI platform)
For global teams, multinational companies, or anyone who presents to non-English audiences, this isn't a nice-to-have — it's a requirement.
Gamma
Primarily English-focused. Some European languages are supported, but the depth isn't there. Asian language support is limited, and the AI's cultural/contextual understanding in non-English languages can produce awkward results.
Tome
English-first. Minimal multilingual capability. If you need a deck in Mandarin or Japanese, Tome isn't built for that.
Verdict: If you work in multiple languages — or your audience does — Felo Slides is the only serious option in this comparison.

Migrating From Gamma or Tome to Felo Slides
If you're currently using Gamma or Tome and considering a switch, here's what the transition looks like.
From Gamma to Felo Slides
- Export your existing Gamma decks as PDF (your only export option)
- Import content into Felo Slides — paste the text from your PDFs, or better yet, feed Felo the original source URLs
- Rebuild using Felo's templates — you'll find the customization options significantly more flexible
- Export to PPTX for any offline or corporate needs Gamma couldn't serve
The biggest adjustment: Gamma's card-based layout maps to traditional slides differently. Think of it as gaining structure rather than losing freedom.
From Tome to Felo Slides
- Export your Tome decks as PDF
- Identify your core content — Tome's narrative structure often has great storytelling buried in cinematic formatting
- Recreate in Felo Slides using the text/paste input, or feed it the original source material
- Apply custom templates that match your brand (something Tome couldn't do)
General Migration Tips
- Don't try to replicate your old decks exactly. Use the migration as an opportunity to leverage Felo's input sources — feed it the original research, articles, or data that informed your old presentations.
- Test the multilingual features if you haven't used them before. Many teams discover they need this capability only after switching.
- Start with the free tier. Build a few decks, compare the output quality to what you were getting in Gamma or Tome, and then commit.

Yes. Felo Slides offers a free tier that lets you generate, customize, and export decks without paying. Pro plans are available for higher usage limits and team features.
Can I export AI-generated slides to PowerPoint?
Felo Slides supports PPTX export. Gamma and Tome do not — they're web-only tools with PDF as their most portable export format.
Which AI slides tool is best for non-English presentations?
Felo Slides supports 20+ languages with deep, native-quality generation. Gamma and Tome are primarily English-focused with limited multilingual capability.
Can I use a YouTube video as the source for a presentation?
Yes — Felo Slides accepts YouTube URLs as input and generates a structured deck from the video content. Gamma and Tome don't support this.
Is Gamma better than Felo Slides for design?
Gamma has stronger default visual polish for web-native presentations. Felo Slides offers more customization control and traditional slide formats. The "better" choice depends on whether you value out-of-the-box aesthetics (Gamma) or flexibility and editability (Felo Slides).
Can I collaborate on presentations in real time?
Gamma and Tome both offer real-time collaboration. Felo Slides supports sharing via link, with collaboration features continuing to expand.
What's the best AI slides tool for startups?
It depends on your use case. For investor pitch decks with cinematic flair, Tome works well. For web-native presentations with strong design, Gamma is solid. For everything else — especially if you need PowerPoint export, multilingual support, or content sourced from research — Felo Slides is the more practical choice.
How do these tools handle large documents as input?
Felo Slides handles PDF uploads and long-form URL content, extracting key points and structuring them into a presentation. Gamma and Tome require you to provide condensed text input, meaning you'll need to summarize long documents before generating.

The Bottom Line
Here's what we'd tell a friend who asked "which AI slides tool should I use?"
If you need one tool that handles everything — research input, multilingual generation, custom templates, PowerPoint export, and doesn't break the bank — Felo Slides is the answer. It's the most versatile, the most practical, and the most forgiving on pricing.
If design is your only priority and you never need to leave the browser, Gamma is genuinely beautiful. Just know you're locking into a web-only workflow.
If you're a founder building a short, cinematic pitch deck, Tome still has a niche. But that niche is narrow, and the pricing is steep for what you get.
The AI slides landscape is moving fast. A year from now, these tools will look different. But today, the choice comes down to this: do you want a tool that generates pretty decks, or a tool that fits into how you actually work?
