Japanese on-premise and offline AI meeting-minutes tool from Nishika for confidential, security-sensitive organizations.
Castmagic is an AI-powered content platform that transforms recorded audio and video into transcripts and a range of derived content. After a file is uploaded or imported, Castmagic transcribes it with speaker diarization and then automatically generates summaries, show notes, timestamps, titles, social media posts, newsletters, and other assets from the same recording. The platform integrates with sources including YouTube, Apple Podcasts, Google Drive, and Zoom, so recorded meetings and interviews can flow directly into a workspace for processing alongside podcast episodes. Castmagic includes semantic search across a media library, brand-voice customization, reusable templates, and commenting and approval workflows aimed at teams and agencies that manage content for multiple brands. While its marketing centers on podcasters and creators, the transcription, speaker labeling, and summary features make it applicable to meeting and interview recordings as well. It is intended for content teams, marketing agencies, podcasters, coaches, and sales organizations that want to convert recorded conversations into transcripts and repurposed written content rather than only a raw transcript. Pricing varies by plan. Check the official website for current pricing.

SecureMemo is an AI meeting-minutes application developed by Nishika, Inc., a Japanese company, and is designed for organizations that handle confidential or sensitive meetings and cannot use cloud-based services. It runs in on-premise, closed-network, or fully offline environments, processing audio entirely within the customer's own infrastructure so that voice data never leaves the organization to an external cloud. SecureMemo is powered by Nishika's in-house speech recognition AI called "shirushi," which the company states maintains high recognition accuracy even with background noise or overlapping speech, and can transcribe audio in roughly 100 languages including Japanese, English, Chinese, and Thai. The product offers five core capabilities: accurate voice recognition, automatic speaker identification, automatic meeting-minutes generation that organizes decisions and key points, translation across about 100 languages, and custom terminology support through word registration for specialized vocabulary. The workflow follows a simple three-step process of transcription, speaker recognition, and summarization. It is offered in standalone, USB-dongle, and client-server deployment models, with case studies spanning police, government agencies, universities, manufacturers, and financial institutions. A two-week free trial of the standalone version is available. Pricing varies by plan. Check the official website for current pricing.
