Maestra

Japanese-first AI transcription and meeting notes across web, mobile, and Chrome.

An AI transcription platform from Tokyo-based Notta Inc. that captures live meetings, uploaded recordings, and in-person conversations, then produces summaries and action items. It is strongest in Japanese — the market it was built for — with support for dozens of other languages, real-time translation, and capture via web, mobile apps, and a Chrome extension. A free tier exists but caps recording length per session.

Real-time AI dubbing, translation, and voice for content, entertainment, and live sports.

A localization AI platform for real-time dubbing, translation, and multilingual voice generation. Its in-house MARS speech models power live commentary for broadcasters and on-demand dubbing for film and OTT, preserving each speaker's voice and emotional tone. Spans live and file-based dubbing, text-to-speech, subtitles, and image translation across 50+ languages.

Podcast + audio editing where the transcript is the timeline.

Audio and video editing built around an editable transcript — cut words, get cut audio. Add AI cleanup, overdub voice clones, and screen-recording for podcasts and tutorials in one tool.

AI translation and writing for text, documents, and apps via API.

A translation service known for fluent, natural output across text, full documents, and a developer API. Pairs the consumer translator and DeepL Write with the DeepL API for adding translation to your own apps. Uses specialized in-house language models rather than a repurposed general-purpose LLM.
