Sixth AI

The AI Coding Agent That Works While You Sleep

Install from VS Marketplace · Discord · Twitter · Website

Sixth AI is an autonomous coding agent that lives inside VS Code. Give it a task, and it will plan, write, edit, and debug code across your entire project — then let you review every change before it's applied. No copy-pasting. No context-switching. Just describe what you want and watch it build.

Unlike basic copilots that suggest one line at a time, Sixth AI thinks through problems, spins up sub-agents for parallel work, and can even be controlled remotely from your phone via Telegram. It's the closest thing to having a senior engineer pair-programming with you 24/7.

Edit Files Across Your Entire Project

Sixth AI doesn't just suggest code — it writes and edits files directly in your workspace. Tell it to add a feature, fix a bug, or refactor a module, and it will create, modify, and delete files as needed, presenting you with a clean diff to approve.

• Multi-file edits in a single conversation — no more juggling tabs
• Automatic error detection — catches missing imports, syntax errors, and type mismatches as it works
• Full diff review — see exactly what changed before you accept anything
• Timeline tracking — every change is recorded, so you can always roll back

Deep Planning Mode

Complex tasks need a plan before code. Sixth AI's Deep Planning Mode breaks down your request into a structured, step-by-step strategy before writing a single line — so the agent doesn't just code fast, it codes right.

• Architectural thinking — analyzes your codebase structure, dependencies, and patterns before proposing changes
• Step-by-step roadmap — see the full plan and adjust it before execution begins
• Fewer dead ends — planning up front means less wasted time on approaches that don't work
• Perfect for big tasks — feature builds, refactors, and migrations that span dozens of files

Sub-Agents for Parallel Work

Why do one thing at a time when you can do five? Sixth AI can spin up sub-agents that work on different parts of your task simultaneously — researching, writing, and validating in parallel.

• Parallel execution — multiple agents tackle different files or concerns at once
• Divide and conquer — the main agent orchestrates while sub-agents handle the details
• Faster results — tasks that used to take 10 minutes now finish in 2
• Smart coordination — sub-agents share context so their work doesn't conflict

Remote Control via Telegram

Start a task on your PC, then monitor and control it from anywhere using Telegram. Sixth AI's remote access lets you check progress, give approvals, and steer the agent — all from your phone.

• Start tasks from your desk, manage them from the couch — or the train, or the coffee shop
• Real-time updates — get notified when the agent needs input or finishes a task
• Full control — approve file changes, provide feedback, and redirect the agent remotely
• No port forwarding or VPN needed — just connect your Telegram and go
