KOTRAIN
Train your models. Run your agents.
Own your machine.
An open-source, local-first AI coding & cowork app. Point it at Ollama, LM Studio, or vLLM in one click, or bring your own cloud keys, and let a model that can actually see and touch your codebases do the work.
No telemetry · no account · your code never leaves your machine unless you say so
SettingsView.tsx and wiring the theme store…01 · THE SURFACE
Everything in one calm window
Unified chat / cowork / code
No mode switching. Ask a question or hand off a task, same window, same thread.
Context inspector
See exactly what enters the prompt, files, guidelines, memory, with live token counts. Toggle and pin anything.
Guardrails by default
Risky commands (rm -rf, force push, curl|sh) prompt before running. Fully configurable: allow, ask, or deny.
Sandbox out of the box
File access jailed to your folders. Optional Docker isolation for shell commands.
Multi-folder index
Add multiple roots. Kotrain indexes files and symbols and searches across them instantly.
Memory management
Global and per-project memory, stored as plain markdown you can read and edit.
Connectors
Linear, Slack, Discord, Gmail, and Google Drive, pull real context into the conversation.
A mascot who trains
Nekko peeks in wearing kendo gear: punches, kicks, and bokken swings while the model thinks.
02 · THE HEADLINE FEATURE
Local models, finally first-class
Most tools bolt local models on as an afterthought. Kotrain is built around them.
- Auto-discover a running Ollama, LM Studio, or vLLM on localhost
- Pull, load, and unload Ollama models from the app
- Manage servers remotely and watch token usage over time
- Bring cloud keys too, Anthropic, OpenAI, OpenRouter, any OpenAI-compatible endpoint
localhost:11434localhost:1234localhost:800003 · WHY KOTRAIN
Not a chat box. Not a blind terminal.
LM Studio runs models. Kotrain runs with your work.
Local model UIs are a chat box around a model, no awareness of your files. Kotrain reads, edits, searches, and runs inside your real codebases: multi-folder index, inline editing, per-project memory, guardrails. Same one-click local setup, but the model actually does the work.
The power of an agentic CLI, with eyes.
Terminal agents are powerful but blind, you can't see what changed without git diff, and editing means leaving the tool. Kotrain gives an IDE-like surface: browse the tree, view files and diffs, edit inline, with every action visible through the Context Inspector and approvals.
04 · SAME APP, ANYWHERE
Run it your way
One engine and one UI across every runtime, pick what fits.
Desktop
Native app for macOS, Windows, Linux.
● AvailableSelf-hosted web
npx kotrain, the same UI in your browser, fully offline.
Docker
docker compose up, workspaces as volumes, local models via host network.
Kotrain Cloud Paid
Hosted, with an always-on Zero-Data-Retention mode, cloud history + files, and your phone driving your local model via a secure E2E relay.
○ PlannedKotrain Cloud keeps inference and tools on your machine, the relay is an end-to-end-encrypted pipe to your own paired agent, so using your local model stays private by design.
