SlimPPT

Overview

SlimPPT is a browser-based presentation tool that lets you import existing .pptx files for online or offline editing and presenting. Built on a local-first architecture, drafts and generated pages are stored in your current browser. Cloud sync is optional, and core operations require no account registration. **Key Capabilities** - **OOXML Standard Compliance**: Parses and renders files according to the Office Open XML specification, supporting 56 transition effects and original animations. - **Multiple Export Formats**: Export to PPTX, single-file HTML, ZIP HTML, PDF, PNG archives, and experimental video formats. - **AI-Assisted Generation**: Uses a BYOK (Bring Your Own Key) model. You configure API Keys from providers like OpenAI, Anthropic, or Google yourself. Keys are stored locally in your browser, and usage fees are charged by the provider. AI can generate slide drafts with charts and transitions across 17 page types. - **Real-Time Collaboration & Presenting**: After logging in, use experimental collaboration features to co-edit shapes, text, slides, and animations via invite links. Live presenting lets audiences follow the presenter's page turns; edits made during a presentation don't affect the audience view. - **Media & Recording**: Record narration and camera footage (Lecture feature). Capture your screen, camera, or microphone and insert the media into the current slide, or export as video following a preset flow. - **Fine-Grained Editing**: Over 90 built-in tools covering masters, backgrounds, fonts, WordArt, animations, and more, plus one-click brand color replacement. SlimPPT is currently in an invite-only Beta, ideal for users who need to work with existing .pptx files in the browser, value privacy, and want AI-assisted editing.
