knot records, transcribes, summarizes, and organizes notes entirely on your iPhone. Unlike Plaud and Pocket, it needs no separate recorder, cloud processing, account, or subscription. Notes, recordings, transcripts, prompts, and AI chats stay on your device unless you export them. Your searchable vault is stored as readable Markdown, so you can inspect the source, keep the files, and take them elsewhere. $14.99 once.
