What it solves

LocalStudio is a browser-native slide editor designed to keep presentation decks editable and local-first, avoiding the risks of cloud sync corruption and the slow process of manual translation. It allows users to maintain full control over their project files and assets while integrating AI capabilities directly into the browser.

How it works

The application runs entirely in the browser without a product backend. It leverages Chrome's built-in AI APIs (Prompt, Translator, and Language Detector) and WebGPU-accelerated models from Hugging Face (such as Gemma 4 and SlimSAM) to perform AI tasks locally. Projects are stored as layered documents in local folders or mirrored to S3-compatible storage (like MinIO, AWS S3, or Cloudflare R2) for public sharing and syncing across devices.

Who it’s for

It is for presenters and creators who want a professional slide editor with AI assistance that doesn't rely on a remote workspace, preferring local-first data ownership and privacy.

Highlights

• AI-Powered Content Creation: Generates editable slide layers (text, images, and shapes) from prompts rather than flat images.
• Prompt-to-Image: Creates image assets locally and drops them directly onto the canvas.
• Local-First Workflow: Supports .pptx import, local project history, and local folder persistence.
• Advanced Presentation Tools: Includes a presenter-mode PWA remote control, live speech-to-text transcription for accessibility, and a RAG-based Q&A app for audience members.
• WebMCP Integration: Exposes editor actions as semantic tools for AI agents to drive the editor state.
• S3 Mirroring: Enables public publishing and project syncing using S3-compatible storage.
