CNVS.app - Free Collaborative Whiteboard

CNVS.app is a free, web-based collaborative whiteboard platform designed for instant sharing and seamless teamwork. It eliminates the friction of account creation—users can jump straight into a shared canvas with a unique link. The interface is intuitive, supporting typical whiteboard elements like drawing, sticky notes, shapes, text, and freehand sketches, all updated in real-time for all participants. Its standout feature is deep integration with AI: users can embed or connect any AI model directly into the board, enabling on-demand content generation, brainstorming assistance, or data processing. Whether you're mapping out ideas, sketching wireframes, or conducting remote workshops, CNVS.app aims to make collaboration fast, creative, and effortlessly smart. The AI integration is seamless and flexible. Rather than locking users into a single AI provider, CNVS.app allows you to bring your own AI—whether it's a large language model, image generator, or custom model—via API keys or simple widgets. This means you can ask a GPT-style assistant to summarize notes, generate design ideas, or explain complex concepts right on the canvas. Image generation models can visualize concepts instantly, making it a powerful tool for creative workflows. The AI's outputs appear as interactive cards or images that can be moved, edited, and discussed by the team. From a technical perspective, CNVS.app leverages modern web technologies to deliver a responsive, low-latency experience. Changes sync in milliseconds, and the platform handles concurrent edits without conflicts. Since there's no account required, privacy is maintained through ephemeral boards—sessions are accessible only to those with the link and can be discarded at will. For users who want persistence, boards can be exported or saved locally. The AI widgets communicate directly with external APIs, so processing happens client-side or via secure backend proxies, ensuring data doesn't get stored unnecessarily. Overall, CNVS.a

Problem solved

Teams and individuals often need to brainstorm or collaborate visually on the fly, but traditional tools require time-consuming sign-ups, have steep learning curves, or lack built-in intelligence. CNVS.app solves this by offering a zero-setup, instantly shareable whiteboard that works in any browser. It further bridges the gap between human ideation and AI assistance by letting users integrate their preferred AI models directly into the board, making sessions more productive and innovative without switching between applications.

Use cases

Remote design sprints: teams sketch wireframes and get AI-generated UI suggestions and placeholder content on the fly.
AI-assisted brainstorming: writers or marketers use the whiteboard to mind-map while an AI widget generates topic ideas, slogans, or outlines.
Educational workshops: teachers draw diagrams and have an AI explain concepts, generate quiz questions, or translate content in real-time.
Project planning: product managers map timelines and tasks, with AI breaking down complex goals into actionable steps directly on sticky notes.
Creative mood boarding: designers collect visual inspiration and use AI to generate images or color palettes that match a theme.
