DeckEdit vs Gamma: Edit Locally or Generate in the Cloud?
DeckEdit is 100% free and runs entirely in your browser — your decks live on your device, no account, no upload. Gamma generates brand-new slides from a text prompt using cloud AI with freemium credit limits and a required account. The two tools serve different intents: DeckEdit edits and converts your decks locally; Gamma generates new ones in the cloud.
The Fundamental Difference
DeckEdit is a slide editor and converter. You bring a deck (blank, template, NotebookLM PDF, or image), and DeckEdit lets you compose, edit, theme, and export it — all locally in your browser. Gamma is a slide generator. You give it a text prompt or document, and a cloud AI invents a deck for you.
Choose DeckEdit if you already have content (or want to build it block by block) and care about privacy and cost. Choose Gamma if you want AI to invent the deck from scratch and don't mind cloud processing, an account, and credit limits.
How Each Tool Works
DeckEdit: Local Editor + Converter
DeckEdit runs entirely in your browser. Decks are stored in OPFS on your device. You compose with 11 block templates, apply themes, drag elements on a 1920×1080 canvas, and export to real PowerPoint. For NotebookLM PDFs, browser-based OCR reconstructs every text element as an editable PowerPoint text box. No account. No upload. No credits.
Gamma: Cloud AI Generator
Gamma takes a text prompt or document and uses cloud AI to generate a deck. Editing happens in the cloud through a web app. The free tier gates AI generation behind a credit pool; heavy usage requires a paid plan. An account is required to use the product.
Privacy Comparison
DeckEdit: Files are processed 100% locally in your browser. Zero network transmission of deck content. No server logs. No data retention. Works offline.
Gamma: Prompts and documents are sent to Gamma's cloud servers. Subject to their data handling policies. Requires an active internet connection.
