Tonic.ai
Synthetic data and test data platform: Fabricate, Structural and Textual for generating and de-identifying data.
What is Tonic.ai?
Tonic.ai builds software that gives engineering and AI teams realistic data without exposing real records. Tonic Fabricate uses a chat-based Data Agent to generate synthetic relational databases, PDFs, DOCX files and other unstructured data, plus mock APIs, and it has an API, MCP server and npm package. Tonic Structural turns production databases into privacy-preserving test data that keeps relationships between tables intact, with data connectors for sources such as PostgreSQL, MySQL, Snowflake, SQL Server and Oracle. Tonic Textual detects and redacts sensitive text in unstructured data for AI workflows. Pricing differs by product. Fabricate is $0 per month on Free with $5 of monthly credits, $29 per month on Plus with $25 of credits, and Custom on Enterprise. Structural Professional and Enterprise are custom priced by source data size, and Textual has pay-as-you-go pricing per 1,000 words plus an Enterprise tier. Enterprise options include SSO and self-hosting.
