- Fetch directly from S3 or Azure Blob.
- Custom proxy hooks for CORS-free loading.
- Handle files up to 100MB+ with client-side fetchers.

Gemini Built In
Live rewrite pipeline ready for editor actions
Built-In Gemini
for Smarter Slides
Gemini-powered refinement ships as part of the product experience, so teams can rewrite content, generate sharper phrasing, and stay in flow without bolting on a separate AI layer.
- Rewrite, shorten, expand, or reframe selected text without leaving the canvas.
- Use built-in AI actions from the ribbon, slash commands, or context-aware menus.
- Keep API keys server-side through your own secure route while SlideCanvas handles the UI flow.
Custom Image Webhooks
for Visual Generation
Plug SlideCanvas into your own image-generation pipeline with a webhook route that can call internal services, hosted models, or custom creative tooling and return ready-to-place assets.
- Send prompt, style, and slide context to any custom webhook-backed image service.
- Return generated asset URLs straight into the canvas for instant placement workflows.
- Keep your preferred model provider flexible while SlideCanvas owns the editor-side experience.
