Key features
- Image-as-Prompt Input: Accepts user-provided images as the primary input to seed visualizations and guide output generation, enabling idea exploration from existing visuals.
- Visual Storytelling Focus: Provides tools and workflows geared toward arranging and refining visual elements into a coherent narrative or presentation to communicate ideas.
- Rapid Prototyping Experience: Positioned as a Labs experiment, Whisk emphasizes quick iteration and exploratory workflows that let users test concepts without heavy setup.
- Web-Based Accessibility: Delivered as a browser-accessible Labs tool so users can try image-prompt workflows without installing software or configuring environments.
- Refinement & Iteration: Supports iterative editing of prompts and visual outputs so creators can progressively refine visuals and story structure (experimental capabilities may vary).
- Use images as prompts to drive visual outputs
- Visualize ideas and concepts from image-based inputs
- Support for narrative/storytelling workflows using images
- Web-based UI hosted under Google Labs (labs.google/fx)
- Experimental preview — intended for exploration and feedback
Best for
- Concept Visualization: Turn a photo, sketch, or mood image into a set of visual explorations to communicate product, design, or branding concepts during early-stage ideation.
- Storyboarding & Narratives: Use images as seeds to assemble visual storyboards or sequences that illustrate a narrative arc for presentations, pitches, or creative projects.
- Marketing & Content Creation: Rapidly prototype visual assets and scene ideas from reference images to inform campaign creatives or social media content planning.
- Creative Prototyping: Experiment with different visual directions by iterating on image prompts and generated outputs to evaluate style, composition, and mood.
- Educational Visual Aids: Create illustrative visual sequences or concept visuals from real-world images to support lectures, lessons, or explanatory content.
- Rapidly prototype visual concepts from reference images
- Create narrative or storyboards guided by image prompts
- Generate visual assets for presentations or social media
- Explore multimodal creative workflows and ideation
