Blackwall - Private AI

AI that works on a plane. The model runs on your phone, so there is no signal to lose and no server to trust. No account, no cloud, free.

Blackwall runs AI entirely on your iPhone. No internet, no account, nothing leaves your phone.

Most AI apps are a thin pipe to someone else's server. Blackwall isn't. The model lives on your device. Your chats, voice notes, and the photos you analyze stay in local storage and are never uploaded.

USE IT WHEN:

• You're on a plane, a subway, a trail, or anywhere with no signal.
• You're handling something private (notes, health, money, work) you don't want sitting on a cloud server.
• You want an assistant with no login, no subscription, and no data collection.

ALL ON-DEVICE:

• Chat with capable local models for writing, summarizing, rewriting, and coding help, now with Markdown and copyable code blocks.
• Talk instead of type. Your voice is transcribed on your phone, and replies can be read aloud.
• Show it a screenshot, receipt, or document. It reads the text locally with OCR and vision.
• Keep every conversation in a private archive you can export or wipe in one tap.

PICK YOUR MODEL. Start with a small one that loads in seconds, download a heavier one for stronger answers, or import your own GGUF file. Qwen, Llama, Gemma, Phi: your hardware, your choice.

Honest about the trade-off: on-device models are smaller than giant cloud models, so they won't beat a data-center model on the hardest problems. What you get instead works with no signal, needs no account, and never uploads a word.

No account. No cloud. No tracking. Free.
