If your charts need a manual,
no one reads them.
Vizmatiq builds the chart, writes the takeaway, and surfaces the outlier, so the person you’re sharing with gets the answer, not a puzzle.
Everything you need to understand your data, nothing you don’t.
Natural Language Charts
Describe what you want to see in plain English. AI generates the perfect visualization instantly.
AI Anomaly Detection
Automatically surface outliers and unexpected patterns hiding in your data.
Shareable Dashboards
Build interactive dashboards and share them with a link. No accounts required to view.
Calculated Fields
Create derived columns with formulas. Ratios, running totals, conditional logic and more.
Drill-down Analytics
Click any data point to explore the underlying rows. Go from summary to detail in one click.
Data Stories
AI writes narrative summaries of your data, highlighting key trends and takeaways.
Every number shows its work. Unverified figures are flagged, not hidden.
When the AI answers, every figure is compared against statistics computed locally from your actual data: sums, averages, group totals, query results. A number gets the badge only when the math reproduces it.
Click any matched figure to see which statistic carries that value. A figure the check cannot reproduce is marked with a question mark, and one that contradicts your data is marked in red, so you know what to double-check.
Revenue totaled $375,000 across 20 rows. South leads with 60% Region “South” share of total Revenue, computed locally of the total.
All 3 figures match a statistic from your data
Three steps. No learning curve.

Your data stays in your browser — AI features are opt-in and send only what they need to Anthropic, with personal data masked.
We don’t sell it. It leaves your browser only when you choose: signing in to sync across devices, sharing a dashboard, or running an AI feature, which sends what that feature needs to Anthropic with personal data masked by default. Each is optional and visible. How we handle data
Simple pricing. Start free, upgrade when you need more.

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 20 AI calls per day with the agent. Pro (US$5/month) raises that to 200 AI calls/day and unlocks database connectors, AI Deep Clean, Data Story templates, shareable links, PDF export, and presentation mode.
- Does Vizmatiq upload my data to a server?
- Local CSV and Excel analysis runs in your browser while signed out. Signing in enables automatic cloud sync of dashboards and datasets within the sync size limit. AI features send prompts and data context, including samples (personal data masked by default), statistics, and query results, to our server and Anthropic. Samples can include every row of a small dataset. Sharing uploads a snapshot; database and Google Sheets imports use server endpoints. See our privacy policy for details.
- 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 offers spreadsheet import, editable dashboards, local SQL, correlations, and an AI agent in a browser interface. You can try local file analysis without an account. Tableau and Power BI offer their own reporting and deployment options, including free offerings. Compare current official plan details, connectors, sharing, and data handling against your requirements; these products are not feature-for-feature equivalents.
- 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, with 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.
