synthBI
The next step after Synth for SQL

Any file in. A dashboard out.

Drop a CSV, JSON, or Excel file and build a dashboard of charts, KPIs, and notes in minutes, by hand or by asking the AI. When it's ready, hand it to Power BI or Tableau. Your data stays in your browser the whole time.

How it works

Upload

CSV, JSON, or an Excel workbook. Each file, or each sheet, becomes a table in a real SQLite database running inside the tab. Related tables are detected so you can join them.

Build tiles

Pick a table, a group-by, and a measure, or write SQL. Choose from 22 visuals, color them your way, and arrange them like slides with text boxes for titles and takeaways.

Export

Download typed Excel tables for Power BI's Get Data, Tableau data sources that open already connected, and an image of the dashboard for decks.

Two ways to use it, both free

Lite Mode (no account)

Everything runs locally. Nothing is sent anywhere.

  • Upload CSV, JSON, and Excel files
  • Build tiles with the visual builder or SQL
  • All 22 chart types, colors, text boxes, layout
  • Table View and relationship detection
  • AI assistant
  • Saved dashboards and export

Normal Mode (free sign-in)

Everything in Lite Mode, plus:

  • AI assistant: ask questions about your data, or describe a chart and fine-tune the draft
  • Save dashboards and open them on any device
  • Export to Power BI and Tableau, plus a dashboard image

Private by design

Runs in your tab

Parsing, queries, charts, and export files are all computed on your computer. There's no server-side database of your uploads.

The AI sees schema, not rows

The assistant gets column names and types. When a question needs numbers, it writes a query that runs locally, and the results never go back to it.

Saving is your call

Nothing is stored in the cloud unless you're signed in and click Save to cloud, and you can delete a saved dashboard at any time.

Turn a file into a dashboard.

No setup, no database, no account needed to start.
