jebi - A supercharged terminal for Mac with built-in local AI
by•
jebi is a supercharged Mac terminal with built-in local AI — no API key, no subscription, no cloud.
After every command, it suggests what to run next. Hit an error? jebi explains it in plain English and tells you how to fix it. Type /ask to chat with AI right in your terminal.
All AI runs on-device with Qwen, Phi-3, and Gemma — your commands never leave your Mac. Beautiful UI, split panes, tabs, custom themes, grain texture, and slash commands like /ls and /ports.

Running local AI after every command is such a thoughtful UX — it flips the terminal from reactive to proactive. Did you find Qwen vs Phi-3 vs Gemma meaningfully different for the command-suggestion use case, or do they all land around the same quality?

@dannyheng Thanks! Qwen does edge out Phi-3 for this use case — it handles shell context and command names more reliably, especially with less common CLIs. The gap isn't huge for everyday commands; Qwen just tends to hallucinate less when the output is messy or truncated.
Local AI in the terminal is interesting specifically for the privacy angle - no API calls, no data leaving the machine. What model are you running locally, and how did you approach the tradeoff between model size and response latency? Inference speed feels like the main constraint here.

@demi_tan Exactly — privacy was the primary driver. The whole point is that your session context (commands, output, working directory) never leaves your machine, and that only works if inference is local.
On the model side, we support a few options that users can switch between. The latency tradeoff is real — we lean toward smaller, faster models since the use case is suggestion and assistance, not deep reasoning. A 200ms response after every command feels natural; a 2s wait breaks the flow.
