Tomat AI
Tomat AI is a desktop app for Windows and macOS that lets you clean, transform, and analyze Excel and CSV files without writing formulas or code. You download the app, open files locally on your machine, and build visual step-by-step workflows with drag-and-drop transforms like filter, sort, merge, pivot, and branch.
The product is built around two layers: visual data prep and row-level AI. For prep, Tomat offers 20+ visual transforms and 150+ functions to restructure large spreadsheets without uploading them to the cloud. For AI, you write a prompt once and run it across every row in a table, with optional web search for bulk enrichment and research.
Tomat also ships reusable AI templates for tasks like text summarization, address standardization, email personalization, and CRM data cleanup. Workflows can include prompt chains for multi-step jobs, charts for reporting, and exports to PDF. Connectors cover CSV, Excel, PostgreSQL, and Snowflake, with access to 450+ additional sources available on request.

How do I use AI in Tomat?
Download and install the Tomat desktop app, create a workflow, add a Source node to load a CSV or Excel file, then add a Use AI node with your prompt. The AI processes each row individually and only sees columns referenced in the prompt. Enable Web Search in the AI node to research the web in bulk.
How much does Tomat cost?
Tomat offers a free 7-day trial with no credit card required. The Solo plan costs $7 per month for one user. Team pricing starts at three users and requires contacting sales. Additional AI credits can be purchased from the Account page in the app.
How do I buy AI credits?
After the trial, select the Solo plan on the Account page in the Tomat app and add AI credits starting from 100,000 credits for $5. Larger credit packs reduce the per-credit cost.
How many AI credits do I need?
New accounts start with 30,000 trial credits. Each credit equals one token, roughly 3 to 4 English characters. Typical verification, summarization, or sentiment tasks on 10 to 15 datasets with about 1,000 rows each usually need 500,000 to 1,000,000 credits. Simpler extraction or calculation jobs often need 100,000 to 200,000 credits.
Does Tomat work with databases besides CSV and Excel?
Yes. Tomat supports PostgreSQL and Snowflake connectors in addition to CSV and Excel files. Contact Tomat to request access to more than 450 additional data sources.
What operating systems does Tomat support?
Tomat runs on Windows and macOS as a downloadable desktop application.
Is Tomat safe for sensitive data?
Tomat processes files on your local machine, and the company states your files do not leave your laptop unless you choose to send specific data to AI providers. AI enrichment uses the official OpenAI API and only sends the data you ask it to process.
