All AI inference runs on your device. Your videos and summaries never leave your phone — no servers, no tracking.
Get the key points of a 1-hour video in under a minute. Choose between Standard or Casual tone to match your style.
Listen to summaries hands-free with built-in text-to-speech and word-by-word highlight for easy reading.
Supports 10 interface languages. On-device translation can produce summaries in a language different from the video.
Paste article text or load a PDF — GistAI summarizes written content just as easily as video.
Every summary is saved locally so you can revisit, re-read, or share any past summary at any time.
Drop in a YouTube URL, Bilibili link, TED talk, Vimeo video, or paste article text directly.
GistAI retrieves publicly available subtitles and runs the Gemma AI model locally to generate a structured summary — no internet required after the first setup.
Get bullet-point key ideas, listen with TTS, or share the summary with one tap.
