Hmmm by Cormac

Hmm..? underlines magnitude claims as you read — statistics, percentages, comparatives and provides a skeptical question. It is not a fact checker, its a tool for testing your understanding of the magnitude claims you are reading.

Requires a local qwen3:4b model ('ollama pull qwen3:4b'). Ollama must be started with OLLAMA_ORIGINS=moz-extension://* so it accepts requests from the extension.

A setup page opens when you install and walks you through each step. Without Ollama running, the extension does nothing.

All processing happens on your machine. Paragraph text is sent only to the Ollama server running on your own computer at localhost:11434. There is no telemetry and no analytics. Webmail, banking and health sites are excluded by default; you can turn any site on or off from the toolbar button.

Analysed paragraphs are cached, so revisiting a page is instant. The first question on a fresh start takes up to a minute while the model loads into memory.
