Introduction

Sarathi is a local-first, multi-model autonomous coding agent. It plans, writes, and verifies code on your machine — using the models you choose, with the keys you control.

What makes Sarathi different

Most AI coding tools are chatbots that happen to emit code. Sarathi is built around a verification loop: it doesn't just write code, it proves the code works before handing it back to you.

The agent runs as three cooperating roles:

• Planner — decomposes your goal into a directed graph of tasks, each routed to the right model for its complexity.
• Coder — writes files using a streaming state machine that handles reasoning models, markdown blocks, and surgical edits.
• Verifier — starts dependency servers, probes endpoints, runs a real headless browser, and checks imports and SQL. Returns a genuine pass or fail.

Local-first by design

Your source code never leaves your machine. Sarathi talks to model APIs you configure (OpenAI, Anthropic, DeepSeek, MiMo, and more) using keys you supply — it never proxies through our servers for inference.

                  writes + verifies files locally

# What it does NOT do
✗ upload your code to neuralsarathi.io
✗ proxy inference through our servers
✗ phone home with telemetry
