Mantid: developer tools for small businesses and analysts
Official site link, not an affiliate link. We do not have an approved referral link for Mantid.
Mantid helps you build software by this route: train prediction models and custom LLMs on your own data, locally on a Mac. It is best for small businesses and analysts who want a quick prediction model from their own spreadsheet, without ML skills. People also use it to find answers you can check. A free plan is available.
What it does
Mantid reads a spreadsheet, an export or a folder of documents, suggests questions your data can answer, and trains a model locally: either an ML model that predicts and forecasts, or a custom LLM trained on your documents. Mantid says every model is measured against the simplest guess anyone could make from the same data, and tells you whether it beat that guess and what would help if not. Retraining keeps versions, and models can be exported or called from AI tools through a local MCP.
