Talk2Data

Interactive data analysis platform — query your data conversationally. Translates prompts into SQL and renders visual results.

Talk2Data

The challenge

Non-technical team members needed to answer their own data questions without waiting on an analyst to write a query every time.

Our approach

  • 1

    Built a natural-language-to-SQL layer with schema-aware prompting so generated queries match the actual database structure.

  • 2

    Added a validation step that checks generated SQL for safety and correctness before execution.

  • 3

    Rendered results as auto-selected charts (bar, line, table) based on the shape of the returned data.

Capabilities

  • Natural language to SQL translation
  • Automatic chart selection
  • Query history and reuse
