Frequently Asked Questions
Answers to common questions about VizChat canvas, AI prompting, widget types, data privacy, browser support, and feedback channels.
This FAQ covers product-level questions. For billing and subscription questions, see the Pricing FAQ.
1. Which browsers does VizChat support?
We recommend the latest two major versions of Chromium-based browsers (Chrome, Edge, Arc). Safari 17+ and the latest Firefox run the core features, but canvas animations and custom widgets perform best on Chromium. IE 11 is not supported.
2. Where is my canvas data stored? Is it private?
All documents, widgets, and conversation history are stored in managed Postgres on Google Cloud (US region) and Cloudflare R2 object storage, with TLS in transit and encryption at rest. VizChat is single-player today: only the account owner can reach the data. Your private content is never used to train models. See Workspace sharing for the handoff paths that do work today.
3. Can I use VizChat offline?
Not today. VizChat is a SaaS product — AI chat and the Marketplace both depend on cloud services. Already-loaded canvases are cached for responsiveness, but new sessions, widget generation, and exports require connectivity.
4. Can I invite team members to a Workspace?
Not yet — VizChat is single-player today. A workspace belongs to one account, and there is no membership, role, or invitation flow. See Workspace sharing for the handoff paths that do work today.
5. What happens to my data if I delete my account?
Deletion takes effect immediately and cannot be undone — there is no grace period. Your documents, workspaces, conversations, and uploaded files are erased in one pass. Widgets you published stay in the Marketplace under your username, which is never reissued to anyone else. Subscriptions are cancelled at deletion and any remaining credits are forfeited.
6. How do AI prompts work best?
Three tips: be specific (describe the data source, audience, and visual intent); break it into steps (let the AI sketch the outline first, then refine widget by widget); ground it in context (select a widget or text before asking — the Agent will attach that context automatically). You can also mention things inline in chat: @ pulls up your documents, and @widget: pulls up widgets.
7. Can I export a storyboard as a video?
Not at the moment. Storyboards play back in the app and in full-screen present mode, and can be packaged as a portable .vizpkg together with the files they reference. Video, PDF, PNG, and SVG export are all unavailable right now.
8. Which AI models does VizChat use?
By default we route through the OpenRouter registry, dispatching each task to an appropriate model (chat, vision, code). You can enable BYOK in settings and use your own key from any of the supported providers — see BYOK for the current list.
9. How do I report a bug or suggest a feature?
Open the account menu in the top-right of the header and choose Feedback. For urgent security issues, email contact@vizchat.ai. We respond within five business days; for privacy rights requests (access, deletion, or a copy of your data) see Contact & Support.
10. Is there an API or CLI?
A widget CLI is already available — see Publish a widget from the command line. A general-purpose public API is not available yet. Custom widgets can call external services from their own code.
