People are noticing.
From lecture halls to boardrooms — Humble Zen meets you where you are.
I recorded every lecture this semester and never once re-read the transcript. I just asked it what I needed to know. First time I've felt actually prepared going into finals.
I used to spend an hour after every client call writing up notes. Now I record, get the summary, and I'm done in two minutes. The chat feature is the part I didn't know I needed.
I tried Otter but I wasn't comfortable with my calls being uploaded. The fact that Humble Zen transcribes on my phone changed everything. I use it for every meeting now.
I cancelled four note app subscriptions this year. Paid $19.99 for Humble Zen once and haven't looked back. The math is embarrassing in hindsight.
I have 60 lecture recordings from this year. I typed 'what did anyone say about supply chain disruptions' and got hits from three different classes. Genuinely useful.
Common questions.
Humble Zen is an AI-powered note-taking app that turns voice recordings, audio files, PDFs, and YouTube videos into summaries, flashcards, quizzes, cheat sheets, and a searchable knowledge base.
Humble Zen uses an embedded Whisper model that runs directly on your iPhone. Your audio is transcribed locally — nothing is uploaded to any server. It works offline too.
You can record live audio, import MP3, MP4, WAV, or M4A files, drop in a PDF, or paste a YouTube URL. One app for every type of source material.
Instead of matching exact keywords, semantic search understands the meaning of your question and finds relevant content across all your notes and folders. Ask in plain English and get precise results.
Summaries, flashcards, quizzes, chat, and cheat sheets use a small amount of AI compute. Credits are purchased in packs — no expiry, no subscription, no surprises. Transcription is always free.
Transcription happens entirely on your device. When you use AI features, only the transcript text is sent to generate the result — never your audio. Humble Zen does not sell your data or use it to train AI models.
$19.99 one-time unlocks Pro for life. AI features run on credits you can buy in small or large packs. The free tier includes unlimited recordings and on-device transcription.
No. Humble Zen is a one-time purchase. No subscription, no annual renewal, no trial that silently charges your card. Pay once, own it forever.
