Hey Product Hunt! 👋

Jack is built around a simple idea: your phone should be able to help with your personal content while keeping the processing on your device.

Jack is a native iPhone and iPad assistant for everyday tasks:

💬 Ask questions, brainstorm, and improve a draft.

🎙️ Record and transcribe speech, or import an audio file.

🌍 Read live speech translations.

📷 Ask about a photo or extract its text.

✅ Turn notes into summaries and editable checklists.

You can choose from downloadable local models or use Apple’s on-device model when available. Once the models and languages you need are installed, supported tasks work without an internet connection.

Your prompts, conversations, photos, and recordings stay on your device unless you choose to export or share them. No account is required. Optional usage analytics and crash reporting are opt-in and exclude your AI content.

Jack is available now and free, with no subscriptions or in-app purchases.

You’ll need iOS or iPadOS 26 or later and storage for the models you choose. Performance depends on your device and model.

I’d love to hear what you try first—and where Jack falls short. What’s one task you’d want an offline assistant to handle on your phone?
