Kagi Summarize vs OpenBrief

Kagi Summarize creates summaries of web pages, videos and podcasts when a transcript is available. It accepts URLs for web pages, PDFs, PPTX files, MP3s and videos. Output choices include headlines, brief summaries, digests, medium or long summaries, bullet points and ELI5; users can also translate a summary with Kagi Translate. Kagi lists Cecil as consumer-grade, Agnes as consumer-grade and Muriel as enterprise-grade; Agnes and Muriel are available through the browser extension or API. Summarize is accessible in Kagi search results, through the!sum Bang, in Orion on Apple devices, and in Chrome and Firefox extensions. The API supports text pages, PDFs, PPTX and DOCX files, MP3/WAV audio, experimental YouTube URLs, and scanned PDFs or images using OCR. API requests are limited to 1 MB and require a Kagi account and API credits. A trial includes 100 searches and 100 AI interactions with standard models. Starter costs $5 per month plus tax; there is no free plan.

OpenBrief turns long videos, audio, and recordings into briefs with transcripts, summaries, source-grounded questions, and notes for export. It is intended for material such as research calls, lectures, product demos, interviews, and screen recordings. Add local files or supported web links to a library that keeps source details together. The app uses existing captions where available and transcribes when needed; transcript chat answers are tied to the transcript. Summaries, decisions, timestamps, and notes can be exported to Markdown. The desktop app runs on Linux, macOS, and Windows and does not require an account or sign-up. The homepage says files and generated notes stay on the user's device, and the download page says media processing runs locally. Optional API keys let users choose cloud AI providers: OpenAI, Anthropic, Gemini, or OpenRouter. Requirements include macOS 13, Windows 11, or a current Linux desktop, local disk space, and a local inference stack for transcription, voice generation, and voice cloning. The free plan costs nothing, with no paid plan or trial clock.
