Jazz is an AI agent that lives in your terminal and actually does things. Not a chatbot. Not a wrapper around an API. A personal assistant you control, that reads your files, manages your git, searches the web, handles your email, and automates the workflows you’re tired of doing by hand.

​
Why Jazz?

Because your terminal should be smarter than a blinking cursor. Jazz is a personal assistant that lives where you already work. It can read your filesystem, manage your git repos, search the web, handle your email, run shell commands, talk to APIs—and it does all of it autonomously, step by step, without you having to hold its hand.

​
What can Jazz do?

The short answer: almost anything you can describe. Jazz understands your filesystem, your git history, your shell, HTTP APIs, the web, PDFs and it can connect to external services through MCP. But capabilities are just the foundation. What makes Jazz different is how it combines them to solve your actual problems.

​
Real examples, real workflows

Development 
> review the last 5 commits and flag anything that looks risky
> find all TODO comments, group them by priority, and create a summary
> refactor this function to use async/await and update all callers
> generate a PR description from the current branch diff
Email and communication 
> check my unread emails, summarize anything important, archive the rest
> draft a reply to the latest email from Sarah about the project timeline
Research and analysis 
> research the latest developments in WebAssembly and write a 2-page summary
> compare React Server Components vs Astro islands architecture with pros and cons
> analyze this PDF report and extract the key financial metrics

​
Built to be reliable

Jazz is 100% TypeScript with Effect-TS under the hood. That means every error has a recovery path, every side effect is tracked, and nothing silently fails. It manages its own context window (auto-summarizes when things get long), delegates deep tasks to sub-agents, and gracefully recovers from timeouts and failures. You can throw complex, multi-step problems at it and trust that it won’t fall apart halfway through.
