Gamma Tool Review: The Post-PowerPoint Tool for Nonprofit Proposals?

Gamma presents itself as an AI-powered alternative to traditional slide decks. But is it just "PowerPoint but faster," or does it offer something genuinely new for time-strapped nonprofits? We took it for a spin to find out.

Core Features

• AI slide generation: Type a prompt, get a full deck in minutes.
• AI web pages: Create lightweight webpages instead of decks, perfect for live proposals or reports.
• Design automation: Layouts and styling are applied instantly.
• Collaboration: Real-time editing and commenting.
• Export options: PDF, PowerPoint (with caveats).
• Embeds: Add charts, videos, and forms for interactive content.

Where It Helps Charities

We tried it for a mock corporate proposal: Gamma built a web-style page with stats, case studies, and a CTA in under 10 minutes. The format felt more alive than a static PDF. Here’s where it shines:

• Corporate fundraising: Replace the heavy PowerPoint with a live, mobile-optimised proposal link.
• Trust & foundation bids: Impact reports and proposals in web format stand out from static decks.
• Volunteer/staff onboarding: Create quick, clean-looking packs without design overhead.
• Training and workshops: Generate structured decks in minutes to brief staff.

Strengths

• Speed: A first draft is ready in minutes.
• Design polish: Looks good even with no design skills.
• Web-native output: The option to deliver live, mobile-ready proposals is a big shift.
• Ease of sharing: Send a link, embed it online, or export.

Weaknesses / Watch-outs

• Branding limits: Colours, fonts, and layouts are rigid.
• Unreliable exports: PowerPoint/Google Slides exports often break formatting or sizing.
• Generic copy: AI text works as scaffolding but needs significant rewriting.
• No offline mode / API: Entirely cloud-based, so you’re tied to Gamma’s platform.

Data Privacy & GDPR

Gamma is US-based, storing data on US servers. It’s not explicitly GDPR-first, and there’s limited transparency about model training.

Our traffic light rating: 🟠 Amber

Safe for general fundraising decks, proposals, and reports. Not suitable for sensitive donor or beneficiary data.

Cost & Plans

• Free plan: Limited decks with a Gamma watermark.
• Paid plans: Start from ~$10/month for more credits and no watermark.

Each deck/page consumes credits. Free credits don’t auto-renew, so charities using it regularly will likely need a paid plan.

Free Prompt Flow to Steal

Don’t leave Gamma guessing. Write your outline first in a tool like Claude or ChatGPT:

Draft a 5-section outline for a corporate fundraising proposal: 1. Introduction 2. Our Impact Stats 3. Case Study 4. ROI for Partner 5. Next Steps

Paste this outline into Gamma, and you'll get a structured deck or webpage instantly. This avoids vague results and saves you from wrestling with Gamma’s internal prompts.

Alternatives

• Canva: Better branding control, but slower for the first draft.
• Beautiful.ai: Similar auto-slides, but with fewer web options.
• PowerPoint + Copilot: Best for organisations embedded in Microsoft, but still slide-centric.

Verdict

Gamma isn’t just “PowerPoint but faster.” Its web-page mode hints at a bigger change: proposals and reports that live online, are mobile-ready, and share like a link, not an attachment.

For charities, that could mean pitching corporates with something that feels fresh and professional—while also saving staff hours. Just be ready to edit the copy, and don’t expect full brand control.

⭐⭐⭐⭐☆ (4/5) – A time-saver and a glimpse of the post-PowerPoint era.
