Less noise. More signal. Cut your AI token consumption by up to 90%.

OMNI is a smart terminal layer that intelligently filters and prioritizes command output before it reaches your AI agent. By preventing your AI from getting confused by noisy output, you get accurate answers faster while saving massive amounts of token costs.

Fully transparent. You're always in control.

The Problem: Expensive Tokens & Noisy Outputs

When you use autonomous AI agents (like Claude Code) in your terminal, they read everything. A simple git diff, npm install, or cargo test command can easily dump 10,000 to 25,000 tokens of useless terminal noise into your AI's context.

This causes three huge problems:

1. It's extremely expensive: You pay real money for every single token of that junk output.
2. It makes the AI "dumb": Critical errors get buried under megabytes of warning logs and loading bars, confusing the AI and diluting its reasoning.
3. Model Lock-in: Advanced agent frameworks force you to use their most expensive flagship models just to have a context window big enough to handle all that noise.

The Solution: Omni

I built Omni because I wanted to run AI agents efficiently and cheaply every single day in my own workflow.

Omni acts as the perfect filter between your terminal and your AI.

The result? You can run your AI agent on a super-advanced framework and feed it zero noise. Because the AI is only fed highly focused, straight-to-the-point context, even affordable or ordinary models will perform on-par with expensive flagship models, since they are never distracted by junk data.

My ultimate passion isn't to monetize this—it's to build the ultimate open-source toolbelt for the Agentic AI era. By aggressively saving token costs, I can develop software robustly and cost-effectively today, and you can too.

The Philosophy

OMNI wasn't built just to "cut context" or "save tokens"—those are simply the happy side effects. The true philosophy behind OMNI is Context Quality.

AI agents like Claude are only as smart as the context you feed them. When you flood them with megabytes of dependency logs or loading bars, you force them to sift through garbage to find the actual problem. This dilutes their reasoning and leads to degraded or unhelpful responses.

OMNI's goal is to feed your AI pure, highly-dense signal. This means only grabbing the context that is actually important and meaningful for Claude. We clean up the noise the AI doesn't need, which means:

1. Automatically, the tokens you use are drastically fewer.
2. The AI's response is of significantly higher quality because its context window is laser-focused on the real problem.

Try it for a week. Feel the difference in the quality and speed of your AI's reasoning when it's fed on a diet of pure signal instead of raw terminal noise.

Features Explained

• No More AI Confusion: Omni acts like a smart sieve. If a test fails, it shows the AI only the specific error line and stack trace. Your AI stops getting distracted by loading spinners or noisy dependency logs, allowing it to focus directly on the real problem.
• 90% Token Reduction: By completely eliminating useless terminal noise, you drastically cut your agentic API bills instantly.
• Zero Information Loss: Worried Omni filtered something important? Don't be. Omni saves the raw output in a local archive (RewindStore). If the AI actually needs the full log, it can just automatically ask for it.
• Session Intelligence: Omni remembers what you are doing. It knows which files you are actively editing and stops feeding the AI context it already knows, saving even more tokens over time.
• Distill Monitor: Track your token savings and costs over time. Just run omni stats to see how much money and space you've saved.
• Visual Impact (omni diff): See exactly how much money and space you are saving. Just run omni diff to see the bulky raw output compared side-by-side to Omni's sleek, filtered version.

Loading

Quick Start & Installation

Omni is incredibly easy to set up. It natively integrates into your terminal.

macOS / Linux:

# 1. Install via Homebrew
brew install fajarhide/tap/omni

# 2. Setup Omni (Hooks + MCP Server)
omni init --all

# 3. Verify it's working
omni doctor

# 4. Or auto-fix any issues
omni doctor --fix

# 5. Check Current Status
omni init --status

Universal Installer (macOS / Linux / WSL):

curl -fsSL omni.weekndlabs.com/install | bash

Windows (PowerShell):

irm omni.weekndlabs.com/install.ps1 | iex

How to Use It

Once installed via omni init --all, OMNI works invisibly in the background. Whether your AI Agent runs a terminal command via MCP or you manually pipe output (ls | omni), OMNI automatically jumps in as a transparent layer. It intelligently filters terminal output, removes the noisy logs, and hands the clean signal back to the AI.

To review how many tokens (and how much money) you've saved today, just type:

omni stats

Need to see the filters in action or add your own custom rules? You can easily create your own rules using simple TOML files.

Works Even Better with Heimsense

Omni is part of my personal AI toolbelt. If you use claude-code, I highly recommend pairing Omni with my other project: Heimsense.

Heimsense unlocks restricted environments like claude-code to run with any free or OpenAI-compatible model, rather than forcing you to use expensive Anthropic ones. Omni + Heimsense = Run world-class agent frameworks using affordable models with zero noise and pinpoint accuracy.
