Shortlist Amberscript when transcribing interviews, research, and media for accurate records matters most, and Kai for Chrome when generating quick meeting summaries and action items without any setup matters most. Run both through a week of actual calls to see which suits your workflow.
Audio and video to text service offering automatic and human-verified transcripts and subtitles.
A Chrome extension that transcribes and summarizes meetings entirely on-device in the browser, with no bot, no account, and no upload.
Amberscript is a speech-to-text service that converts audio and video into text and subtitles, offering both automatic AI transcription and human-verified options. Users upload recordings and choose between editable automatic transcripts produced by speech recognition or expert-reviewed transcripts refined by professional editors for higher accuracy. The platform similarly provides subtitles in either automated or professionally edited form, including translation services, and offers a transcript editor for reviewing and correcting output. Amberscript supports a large number of languages and additionally provides a speech-to-text API and data annotation services, as well as a meeting transcription offering for capturing and converting spoken meetings into text. The combination of self-serve automatic transcription and a human-review tier lets users trade off speed against accuracy depending on the use case. Amberscript is aimed at researchers, media organizations, businesses, and public-sector users who need reliable transcripts and subtitles, including those with accuracy or accessibility requirements that justify human-reviewed output rather than automation alone. Pricing varies by plan. Check the official website for current pricing.

Kai is a Chrome extension that transcribes and summarizes meetings entirely within the browser, running the full pipeline on the user's own device. Built by Morgen, the team behind the Morgen calendar app, it captures audio from any meeting or audio tab in Chrome, including Google Meet, the Zoom web client, and Microsoft Teams, without sending a bot into the call and without requiring an account or sign-up. Recording is triggered with a keyboard shortcut from the meeting tab. Audio capture happens in an offscreen document inside the extension and is transcribed locally using a Whisper speech-to-text model running via WebGPU or WebAssembly, so the audio never leaves the machine. At the end of a call, a local language model produces a clean summary with decisions, topics, and action items, including who is responsible. A side-panel interface lets users follow the transcript live during the meeting, and notes can optionally be emailed to a team in one click, at which point only the final text is shared. This makes Kai well suited to individuals who want fast, private, browser-based meeting notes without installing a desktop app or adding a visible bot, with an initial focus on English-language meetings. Pricing varies by plan. Check the official website for current pricing.
