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 in the browser: AI chat, the Marketplace, and widget generation all depend on cloud services. The desktop app can: workspaces connected to a local folder open and edit in the app while offline, and sync back once you're online. Publishing, the Marketplace, and cloud AI chat still need a connection.
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?
Yes, in the desktop app: Export video in the properties panel exports the storyboard with its narration as an MP4, rendered and encoded on your computer, which needs a hardware video encoder (every Mac has one; most Windows PCs do). On the web, the same button guides you to download the app. See Export Overview. PDF, PNG, and SVG export are still unavailable.
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.
11. Can boards play inside Claude or ChatGPT?
Yes. When VizChat is connected to Claude or ChatGPT and the assistant shows a board, it plays right in the conversation — the latest version of a board in your workspace, or the published version of a published board. It is fetched again each time you open it, so reopening an old conversation shows the board as it is now ("Updated since it was shown" when it changed; a notice if it was deleted). Widgets that render their own embedded page (such as the PDF viewer) can't be nested inside Claude's player and show Open in VizChat instead. If the connection has expired, reconnect VizChat in the app's settings. Purchases always happen on the VizChat site.
