Focusky vs OpenDeck

Focusky is a presentation maker for online and video presentations, PowerPoint-to-video conversions, mind maps, and product or service displays.

Creation tools include text, images, video, background music, shapes, formulas, charts, screen recording and voice narration. Output formats include HTML, EXE, ZIP, APP, MP4 and PDF; APP output runs on Mac OS. A mobile app can access and present Focusky presentations online or offline. Focusky lists PowerPoint import, source PowerPoint download, presenter mode and customizable encryption settings. The free plan includes 10G cloud storage and 50 uploads per month, with a watermark on published presentations and limited output and online features.

OpenDeck is a free player for self-contained presentation documents in the `.deck` format. An AI agent can build a deck from a talk description, document, or spreadsheet, including its structure, slides, motion, and voice narration. Decks can also contain toggles, drag-to-reorder controls, and tap-to-reveal interactions. Users can export a `.deck` file for OpenDeck apps or a standalone HTML page. A `.deck` file includes what it needs for playback and can run offline without depending on a server. OpenDeck runs on iPhone, iPad, and Mac; exported HTML decks open in modern browsers on any device. The homepage lists browser and Windows apps as available and says Android is coming soon. Setup options are offered for Claude Code, Claude web, Claude desktop, Antigravity CLI, OpenCode, and Codex. OpenDeck is free forever with no in-app purchases. Its privacy policy says the app collects no personal data and makes no network requests, and that imported decks remain on the device. The app is Apache-2.0 licensed, its authoring kit is MIT licensed, and the `.deck` format is CC0 public domain.
