Kagi Summarize
San Francisco, California, United States
What it is
Kagi Summarize turns web pages, documents, videos, and audio into summaries. The website accepts URLs for web pages, PDFs, PPTX files, MP3s, and videos; podcast and video summaries require an available transcript. Readers can choose formats ranging from a headline or brief digest to longer text, bullet points, or an ELI5 explanation, and can optionally translate a summary with Kagi Translate. Kagi lists Cecil as consumer-grade; Agnes is consumer-grade and Muriel enterprise-grade, with the latter two available through the extension or API. Summarize is available in Kagi search results, through the !sum Bang, in Orion on Apple devices, and via Chrome and Firefox extensions. API formats also include DOCX, WAV, experimental YouTube URLs, and scanned PDFs or images processed with OCR. API requests have a 1 MB size limit and require a Kagi account and API credits. A free trial includes 100 searches and 100 AI interactions with standard models. Starter costs $5 a month plus tax; no free plan is listed.
