Tomat.AI is a desktop application for people who work with CSV and Excel files. It lets users clean, merge, pivot and restructure data through visual, step-by-step workflows instead of formulas or code. The app runs on Windows and macOS, and files stay on the local machine.
On top of the workflow builder, Tomat.AI adds AI processing for tables. A user writes a prompt, tests it on a few rows and applies it to a full dataset. The site describes uses such as web research, enrichment, extraction, summarization and sentiment analysis.
A user downloads and installs the app, creates a workflow and adds a Source node to load a CSV or Excel file. Further steps, such as filter, sort, group, merge, stack, pivot or branch, are added with drag and drop. Each step shows a preview of the result.
For AI tasks, the user adds a Use AI node and enters a prompt. The AI processes each row one at a time and only sees the columns mentioned in the prompt, so it cannot use other columns or multi-row logic. Turning on Web Search lets it research the web for each row.
The main AI features are bulk prompts, prompt testing on a sample of rows, prompt chains for multi-step tasks, and optional web search. The site says AI can run over datasets from 1 to 1M rows. The workflow side offers merges, pivots, branching and reusable pipelines.
For analysis, Tomat.AI shows data quality, unique values, distributions and key statistics. Users can add charts to workflows and export reports as PDF. The pricing page also lists 20+ visual transforms and 150+ functions, along with PostgreSQL and Snowflake connectors.

Each AI credit equals one token, roughly 3-4 English characters. Usage depends on the number of rows, the data sent to the AI and the response length. The site suggests 500,000 to 1,000,000 credits for verification, summarization or sentiment tasks on 10-15 datasets of about 1,000 rows each.
