Chat with real context
Attach files, folders, your selection, problems or git changes with @, or paste screenshots and UI mockups for the model to follow. Large content is compressed to fit the model.
AI coding assistant for VS Code
Code with AI on your models. Approve every change.
Kingcurve brings chat, multi-file edits and a coding agent into VS Code. Run local models with Ollama or LM Studio, or bring your own OpenAI, Claude, Gemini or OpenRouter key. Nothing changes until you say so.
Free · MIT License · Requires VS Code 1.106 or newer
Works with
- Ollama
- LM Studio
- OpenAI
- Anthropic Claude
- Google Gemini
- OpenRouter
- Any OpenAI-compatible server
Everything you need in the sidebar
A complete AI workflow inside VS Code, built so that you stay in control of your code.
Multi-file edits you review
Every change appears as a diff. Keep or drop individual files and changes, apply when ready, and roll back at any time.
An agent team that asks first
Agent mode reads code, edits, runs commands and tests, and can hand parts of a task to team members on other models. Edits and commands wait for your approval.
MCP tools
Connect Model Context Protocol servers over stdio or HTTP, with allow, ask or deny for every tool.
History, tokens and cost
Conversations are saved on your computer. See tokens and estimated cost by day, model and feature.
Git and autocomplete
Generate commit messages from staged changes, review uncommitted work, and turn on inline completions if you want them.
How it works
- 1
Install
Add Kingcurve from the Visual Studio Marketplace. It opens in the side bar on the right, next to your other AI chats.
- 2
Connect a model
Ollama and LM Studio are detected automatically. For cloud models, paste your API key.
- 3
Pick a mode
Ask, Edit, Plan or Agent, depending on how much you want the AI to do.
AskAnswers questions about your code. Read-only.
EditProposes changes as diffs. Works with any model.
PlanInvestigates and writes a plan you approve.
AgentEdits, runs commands and tests, and verifies.
Private by design
Your code, your models, your decisions. Kingcurve never sits between you and your provider.
- No Kingcurve server and no telemetry: requests go straight from VS Code to the provider you choose.
- With a local model, your code never leaves your computer.
- API keys are kept in your operating system keychain, not in settings files.
- Nothing is written to disk until you click Apply. Commands ask before they run, and destructive commands are blocked.
- .env files, private keys and other credentials are never read, and secret-looking values are hidden before sending.
- In untrusted folders, only chat is available.
Frequently asked questions
Is Kingcurve free?
Yes. Kingcurve is free and released under the MIT License. Cloud providers bill you for your own API usage; local models through Ollama or LM Studio cost nothing extra.
Does my code leave my computer?
Only to the model provider you select. Kingcurve has no server of its own and collects no telemetry. With a local model, everything stays on your machine.
Which models can I use?
Any model served by Ollama, LM Studio or an OpenAI-compatible server, plus OpenAI, Anthropic Claude, Google Gemini and OpenRouter with your own API key. Agent mode needs a model that supports tool calling.
Can the agent change files or run commands without asking?
Not by default. Every edit is shown as a diff and every command asks for approval. You can relax these rules in Settings, for example to run commands classified as safe.
Does Kingcurve work offline?
Yes, with a local model. Kingcurve has no server of its own, so with Ollama or LM Studio running on your computer, chat, edits and the agent work without an internet connection.
Can I attach a screenshot or UI mockup and ask it to build the same layout?
Yes. Paste, drop or attach PNG, JPEG, WebP or GIF images (and text or code files), then describe what you want. This needs a model with vision, such as GPT-4o, Claude, Gemini, or a local vision model in Ollama or LM Studio.
Can several models work together on one task?
Yes. In the Agent team tab you can add team members, such as Frontend, Tests or Docs. Each has its own model, allowed tools and the files it may change. In Agent mode the lead agent hands parts of a task to them, and every change still needs your approval. You can also choose a Planner model for Plan mode and a Reviewer model that checks changes.
Can Kingcurve share instructions and work with other AI agents like Claude Code or Codex?
Yes. Kingcurve follows the project instructions in AGENTS.md, the file most AI coding tools read, plus .kingcurve/rules and .kingcurve/memory.md. "Write Handoff" saves the state of a task to .kingcurve/handoff.md, so another agent or teammate can continue it. You can also save conversations as Markdown in .kingcurve/sessions and share an agent team through .kingcurve/team.json.
Which editors are supported?
Visual Studio Code 1.106 or newer. Kingcurve is published on the Visual Studio Marketplace.
