Memo AI

Memo AI is a powerful and privacy-first AI assistant that turns videos, podcasts, and audio files into insightful, translated content with ease. Whether users want to convert YouTube videos, podcasts, or local media files into clean transcripts, subtitles, or condensed notes, MemoAI offers everything needed to streamline the process—all while working completely offline for security.

With video-to-text transcription, MemoAI captures the full content of audio or video in text form, supporting 90+ languages including English, Chinese, and Japanese. Its AI translation is both context-aware and precise, making it easy to switch between languages without losing meaning. The app also features real-time subtitles, speaker diarization for identifying who’s talking, and speech synthesis that turns text into natural-sounding voice output.

MemoAI is designed for speed and performance, powered by GPU acceleration—whether it’s NVIDIA, AMD, or Apple Silicon—making it possible to process a 30-minute file in just 2 minutes. Users can also take advantage of clip segmentation to isolate parts of audio, display floating notes during playback, and generate smart AI summaries (with personal API keys).

MemoAI supports a wide range of formats like MP4, MP3, M4A, AAC, and offers flexible export options including Markdown and Notion integration. It runs smoothly on Windows and macOS, with a beautiful desktop app experience and zero data leakage, ensuring everything stays local and secure.

And the best part? On the free plan, users enjoy unlimited speech-to-text transcription with basic models, unlimited subtitle translations for local files, and unlimited voice synthesis for subtitles and text content—all while experiencing the latest in AI technology, completely for free during the beta.
