Complete feature guide

Everything you need for autonomous engineering.

An architectural review of the capabilities powering the AetherSync IDE and its desktop agent — what each subsystem does, and where its boundaries are.

Core Engine

Autonomous Coding Agent & Multi-File Refactoring

AetherSync breaks down complex engineering prompts into concrete execution plans. It autonomously inspects directory structures, reads relevant modules, executes non-destructive edits, and verifies builds through real-time diffs.

Multi-turn reasoning and tool orchestration
Unified git diff previews before applying modifications
Continuous execution watchdog with graceful interruption

Enterprise Security

100% Local-First Sandbox & Zero Telemetry

Your proprietary code, sensitive configuration files, and terminal environment never leave your local hardware. AetherSync does not harvest source code or train centralized models on your workspace.

OS-level secure keyring for API key encryption
Workspace sandbox preventing directory escapes
Zero background telemetry or analytics on file contents

Native Execution

Integrated Sandboxed PTY Terminal Shell

Spawns full-fidelity interactive terminal instances (PowerShell, CMD, Bash) directly inside your editor. Supports background long-running daemons, build logs, and agent command execution with sub-millisecond response times.

Native Windows CMD & PowerShell pipe management
Interactive REPL support with real-time stream echoing
Granular permission prompts before running risky commands

Universal Intelligence

Frontier Multi-Provider Model Hub

Switch between Anthropic Claude 3.7 Sonnet, OpenAI GPT-4o / o3, DeepSeek R1, or local GPU-powered Ollama instances on the fly without changing your workflow.

Native streaming tool-calling support across all major vendors
Instant model switching without losing conversation context
Local offline inference support via Ollama / vLLM

Cloud Sync

Instant Browser Sign-In & Desktop Deep Linking

Authenticate via Google, Discord, GitHub, or Email using Clerk Auth. Seamless desktop loopback deep-linking connects your profile and settings in one click.

OAuth 2.0 with Discord, GitHub, and Google integration
Session storage persistence across browser redirects
Local offline fallback for air-gapped environments

Editor Experience

Monaco-Powered Code Editor & Custom TitleBar

Enjoy VS Code grade syntax highlighting, breadcrumbs, tabbed navigation, and an Antigravity-inspired custom TitleBar with integrated command palette.

High-performance Monaco engine with 60+ language grammars
Quick-open command palette (Ctrl+P / Cmd+P)
Dark obsidian theme with low-contrast eye comfort
