Frequently asked questions.
- Is Vizmatiq free to use?
- Yes. The free plan covers CSV and Excel import, all chart types, dashboards, natural-language queries, correlation analysis, and PDF export. Pro (US$5/month) unlocks database connectors, AI Deep Clean, Data Story templates, shareable links, and presentation mode.
- Does Vizmatiq upload my data to a server?
- No. Vizmatiq is browser-first — your CSV, Excel, or database rows are processed locally in your browser with DuckDB WASM. Nothing is sent to our servers unless you explicitly click Share to publish a dashboard, in which case only that dashboard payload is uploaded.
- What file formats can I import?
- CSV, TSV, Excel (.xlsx, .xls), Google Sheets links, and direct connections to PostgreSQL, MySQL, BigQuery, and Snowflake (Pro plan). You can also join multiple files on a common column.
- How is Vizmatiq different from Tableau or Power BI?
- Vizmatiq runs entirely in your browser with no install, no server, and no account required to try it. Upload a CSV and get charts, dashboards, and AI-generated insights in under 10 seconds. It targets individual analysts and small teams who don't want Tableau's US$70/user/month price tag or Power BI's Microsoft account requirement.
- Can I share dashboards with people who don't have an account?
- Yes. Pro users can generate a public share link that renders the dashboard for anyone with the URL — no signup needed to view. You can also embed the dashboard in an iframe on your own site.
- What AI features does Vizmatiq include?
- Auto-Mode profiles your dataset on import and suggests charts, KPIs, and a narrative. Data Story generates a PDF report across executive, deep-dive, trend, and comparison templates. Natural-language query lets you ask questions like "which region drove the most revenue in Q3?" and get an instant answer.
- How large a dataset can I load?
- Up to roughly 2 million rows work smoothly in the browser, depending on your device's memory. For larger datasets, connect a live database (Pro plan) and Vizmatiq will push aggregation down to the database instead of loading everything into memory.
