Your Mac can run its own private AI — no subscription, no internet. One problem: it reads big stuff slowly, and it gets forgetful in long chats.

Meanwhile your iPhone sits there, bored. 😴

Good news: it can help — with the cable already in your drawer. 👇

The deal, in plain words:

- ⚡ Your Mac’s AI reads big files up to **44% faster** _(the back half of the work runs on the phone’s graphics chip)_
- 🧠 It remembers **~3× more** of long chats — the oldest part quietly moves to your phone
- 🎯 Answers come out **exactly the same** — checked word-for-word, not faked
- 💸 Cost: **$0** — free tool, free models, one cable

And it gets crazier 🤯

- An **old 8GB MacBook** runs the big brain too — the phone carries half of it ([recipe](https://github.com/StayLameBro/backburner/blob/main/docs/SPLIT-DECODE.md))
- **Two phones** = up to **262k memory** — the chat never has to end ([how](https://github.com/StayLameBro/backburner/blob/main/docs/TWO-PHONES.md))
- In testing: a **~180B model spread across a whole house** — Mac + 2 PCs + 2 phones ([roadmap](https://github.com/StayLameBro/backburner/blob/main/docs/ROADMAP.md))
- Works on **iPhone 15 Pro → 18 Pro** and every **M1 iPad**

And the other devices? They can help 🤝

A **Windows PC or Ubuntu box** joins as a helper today ([Ubuntu guide](https://github.com/StayLameBro/backburner/blob/main/docs/LINUX.md) — brand new, first results wanted 👑). Android and even an Apple TV are on the wish list.

Set it up in 3 steps 🔓

**1.** Mac: paste this one line (free, installs everything):

`curl -fsSL https://raw.githubusercontent.com/StayLameBro/backburner/main/install.sh | bash`

**2.** iPhone: free app via [AltStore](https://altstore.io) — no developer account. (AltStore 2.2+, **not** SideStore — SideStore breaks the magic.)

**3.** Plug in. Done. 🎉

> **🗄️ Fine print & secret perks (1 minute, worth it)**
>
> - 🔌 Any fast USB-C cable works — the one in the iPhone box is USB 2, too slow
> - 🌐 First run: allow **Local Network** when iOS asks — until then it fails silently
> - 🔄 After every Mac reboot: `sudo sysctl iogpu.wired_limit_mb=20480`
> - 📵 Keep the app open on screen while it works — an iPhone rule, not the tool’s fault
> - 💾 16–18GB Macs: run a lighter model, recipe in the README
> - 🛡 Keep the app updated (0.0.3+ fixed an early Wi-Fi hole); the phone answers the cable only
> - 🎁 Secret perks: known chats restart in seconds, a third phone can join over Wi-Fi ([doc](https://github.com/StayLameBro/backburner/blob/main/docs/WIFI.md)), per-device speed table in the README
> - 🤓 For the spec-hungry: the iPhone 17 Pro’s new matrix units make its half **2.4× faster** ; layer splits per device live in the README table (17 Pro: 40, older Pros: 52, M1 iPad: 52)
