LevelCode.ai
The AI-native editor that codes with you. Six agents in quiet orbit — they plan, edit, run, and verify. On your key, on your machine, no middleman.
no account · no telemetry · bring your own key
Autonomous where it earns it.
Gated where it matters.
Every edit lands as a reviewable change. Every command waits for your approval. Before the agent says done, it diffs its own diagnostics and runs your tests — repairing what it broke, bounded and cancellable.
Generate. Describe the change in plain language — LevelCode.ai writes idiomatic code in your project’s style, right in the buffer.
Keep / Undo on every file
Edits land instantly and await your verdict — per file or all at once, live +/− totals, state survives reloads.
Proves itself before reporting
Diffs diagnostics against a pre-run baseline and runs your verify command; new failures loop back for repair — bounded, never runaway.
Rewind any turn
Every agent turn is a checkpoint. One click rolls files, transcript, and pending reviews back to before it ran.
A live terminal, on your terms
Commands stream real stdout/stderr only after you approve; Stop kills the whole process tree — no orphaned servers.
Servers keep running
Long commands detach and keep streaming while the agent works on; it polls output, sniffs the port, tests against the live process.
Real token accounting
A live context meter with actual usage from the provider — click it for the full breakdown. Cost opacity is the enemy.
Drag a whole system onto the canvas.
Predefined agent topologies, ready to run — exactly as they appear on the real board. Drag the Design a Key-Value Store card onto the canvas and it lays down the eleven wired agents from the ByteByteGo chapter — requirements, architecture, storage engine, consistent hashing, replication + quorum, vector clocks, gossip + failover, integrate + server, tests, build + validate, and a review / run-guide. Or drop the Real-time Gaming Leaderboard card for a full Redis-sorted-set build. Set the goal at the top, hit Run, and watch the agents light up in order.
Drag a card onto the canvas to lay down a fully-configured agent topology.
Drop a template here
Drag a template card in — or just click it — to materialise the full topology.
Four subsystems, one editor.
Autocomplete
Debounced ghost text over every file, cancelled the instant you keep typing. Routed to a fast model per provider.
Chat
Streaming chat that knows your project — pin files or let ripgrep + workspace symbols pull context automatically.
Edit
Select code, state the change, review a true side-by-side diff. Keep or discard — nothing applies behind your back.
Agent
State the goal. It plans, edits across files, runs behind approval gates, and verifies before reporting.
Power-editing pack
Keystroke macros, line ops, column mode with incrementing numbers, encoding/EOL controls, big-file mode, hot-exit.
Init script + packages
Code that runs at boot and hot-reloads on save; a package generator with a live dev loop; Atom / NPP / Sublime keymaps.
Sync + import
Built-in Settings Sync, notify-only updates, and one-click import from VS Code, VSCodium, or Cursor.
Fuse it to any intelligence — from your machine.
One registry, hundreds of models. Anthropic runs on a native adapter with prompt caching and full tool use; everything else flows through one OpenAI-compatible pipe. Requests travel from your machine to the provider — no relay, no logging, keys sealed in your keychain.
