Architecture

Three subsystems. One workflow.

Each handles a different layer of your work — from real-time completions to multi-agent architecture planning.

Assistant

Conversational AI

Full project context — files, git diff, terminal, errors. Generates diffs, applies them inline. Chat, slash commands, context menu.

Autocomplete

Inline completions

Real-time code suggestions on a separate model. Independent from chat — zero interference. Type, Tab, done.

Council

Multi-agent planning

Architect, Developer, Reviewer, Tester — four AI agents discuss your task independently, critique each other, then synthesize a plan.

Capabilities

Built for how you actually work

Four interaction modes

Chat with full context. Edit & Apply with inline diffs. Slash commands — /edit, /explain, /test, /council. Right-click context menu for quick actions.

Role-based model system

Seven roles — chat, edit, apply, autocomplete, summarize, embed, rerank. Assign each to a different model. Fast for completions, powerful for planning.

Full project awareness

File structure, open files, selected code, terminal output, error list, git diff, README. The AI sees your entire project — not just the current file.

Local-first, no cloud login

Config lives on your machine in YAML. No accounts, no telemetry. Transfer between PCs with AES-256 encrypted backups.

16 languages — interface and AI responses

Russian, English, Spanish, French, German, Chinese, Japanese, Korean, Portuguese, Italian, Turkish, Ukrainian, Polish, Arabic, Hindi, Dutch. Switch instantly — UI, assistant responses, slash commands, and system prompts all adapt.

Council

Multi-agent planning

A structured 3-phase discussion. No groupthink — each agent thinks independently, then critiques, then a planner resolves conflicts.

1

Independent analysis

Each agent analyzes alone. Proposals, risks, key decisions — without seeing others.

2

Cross-critique

Agents see all responses. Agree, disagree, propose specific changes with reasoning.

3

Plan synthesis

Planner resolves all conflicts. Outputs a step-by-step plan and file structure.
