Your Personal AI — speech and reflection models on Wi‑Fi once, then a private intelligence that lives on your phone.
For the thoughts that are too heavy to carry.
When your mind is racing, typing cannot keep up — and the cloud is not safe for your deepest vulnerabilities. Vent is a hyper-private voice diary that lets you speak your mind in the moment. Everything is transcribed on your phone and locked in an encrypted vault. Catharsis for you, hidden from the rest of the world.
The relief loop
Hold to release.
Hold to release.
Record
When you are overwhelmed, friction is the enemy. There are no titles to write or menus to navigate. Just open the app, hold the button, and speak exactly what you are feeling. Your phone processes the words locally as you speak.
Proof it is private.
Vents
True vulnerability requires real safety. The moment you lift your finger, Vent encrypts your text directly into a hidden vault on your device. The raw audio is destroyed. Your diary never touches Vent’s servers — there is no Vent cloud for your vault.
Make sense of the noise.
Conversations
Get out of the mental loop. Vent includes an optional, on-device AI that acts as a gentle, empathetic mirror. It helps you untangle your rambling thoughts, spot emotional patterns, and ask grounding questions — all offline after setup.
Absolute privacy requires real boundaries.
We do not ask you to trust our privacy policy alone; we ask you to trust the architecture. Vent runs on your physical device, so your private reflections belong only to you.
Auto-wipe
Audio destruction
We do not hoard your voice. Once your vent is transcribed, cached audio is permanently removed from your device.
6 GB+
Typical phones
iPhone 14+ or Android with 6 GB+ RAM for the full Personal AI stack.
Offline
After setup
No internet required for everyday use — reflect securely in aeroplane mode, on a commute, or in the middle of the night.

The comparison
Same need — a place to unburden — different architecture and outcomes.
| Feature | Vent | Typical cloud AI journal | Phone voice memos |
|---|---|---|---|
| The input | Low-friction, hold-to-speak release | Often requires typing and formatting | Raw audio only |
| The safety | Encrypted locally, audio destroyed | Data leaves your phone by default | Unsecured, unencrypted files |
| The reflection | Empathetic mirror stored offline | Generic cloud chatbot | None |
| The outcome | Private unburdening and clarity | Data harvesting risk | A disorganised folder of audio |

Frequently asked questions
Privacy, offline use, and what Vent is — and isn’t.
Product & privacy
What is Vent?
Vent is a voice-first diary app for iOS and Android with on-device transcription, an encrypted vault, and optional on-device reflection and coaching-style Conversations. It is designed for private spoken reflection, not cloud chat.
Does Vent send my diary or Conversations to the cloud?
Diary and conversation content are not uploaded to Vent. Network use is mainly for the one-time Personal AI download.
What is Personal AI?
Vent’s on-phone speech and reflection models (On-device speech pack and reflection model, downloaded once on Wi‑Fi.) — not a remote chat service. Vents and Conversations are not sent to Vent for processing.
How is Vent different from ChatGPT for journaling?
ChatGPT is a general cloud assistant. Vent keeps diary content on your phone, deletes raw audio after transcription, and uses on-device models for reflection grounded in your own entries.
Device & offline use
How much storage does Personal AI need?
~3.4 GB one-time on Wi‑Fi for the speech and reflection models, separate from your diary vault (which grows with your entries). The app shows the exact size for your build before download.
Can I use Vent offline?
Yes, after setup. Recording, transcription, and on-device chat do not require internet.
Does Vent work without Wi‑Fi?
After setup, everyday recording, transcription, and on-device conversations do not require internet. The first-time Personal AI download needs Wi‑Fi (~3.4 GB).
What if I reinstall the app?
Reconnect your vault folder and unlock with your passphrase (iOS Files / Android Documents).
What phones support Vent?
For the full Personal AI stack, plan on 6 GB+ of RAM on typical phones — for example iPhone 14 or later, or Android devices sold with 6 GB or more. The app checks installed memory at setup (technical minimum 5 GB).
Does Vent work on iPhone 13?
Standard iPhone 13 models have 4 GB of RAM and usually cannot install the full Personal AI stack. iPhone 13 Pro and Pro Max have 6 GB and typically qualify. iPhone 14 and later standard models also qualify. The app verifies RAM during setup.
What Vent isn’t
Is Vent therapy?
No. Vent is a reflective practice tool, not therapy or crisis care. If you are in danger or need urgent help, contact local emergency services or someone you trust.
Is Vent a mental health app?
No. Vent does not diagnose conditions, score your mood, or replace professional care. If you are in crisis, contact local emergency services or someone you trust.
Can Vent coach me?
Yes. Vent offers optional on-device Conversations, including coaching-style personas grounded in your own vents. It is not therapy, crisis care, or a substitute for licensed professional coaching.
Is the reflection only mirroring?
You can choose reflective modes that mirror your patterns and ask open questions, or coaching-style guidance — always on device and grounded in your entries, not clinical diagnosis.
If anything here feels heavy, speaking to someone you trust is always worthwhile.
