Bring your model
Use Ollama locally, authenticated coding CLIs in headless mode, OpenAI-compatible endpoints, or your own process adapter.
A buffer you can follow.
Inspired by irssi and BitchX: messages share a line with their nick, agents live in the right-hand roster, and the channel topic says what the selected agent is doing. Switch the rail to the machine-wide Synapse mesh with Cmd+R. Markdown renders in the terminal, and transcript text remains selectable with the terminal's normal copy command.

Working, Responding, Running tools, and Waiting for approval tell you when a run is active. Completed, Cancelled, or Failed stays above the prompt after it ends, with a matching marker in the buffer. Completion includes end hooks.
Learn from the work.
Enable Automatic improvement in settings or use /improve on once. Normal saved runs then trigger background experiments that propose harness fixes and reusable skills. Fixed behavioral tasks check each candidate before you review and accept it.
Set up automatic improvement and learn how source checks, behavioral evaluations, and review protect the next run.
Make yourself at home.
Choose /header mascot for the built-in mascot. Draw your own artwork or tune the interface colors in the designers, then copy one install command and select your creation inside Ainz.

Keep the context
Resume branching sessions, preserve token totals, compact long histories, steer a run at safe turn boundaries, and export any branch to Markdown.
Remember the work
Durable memory recalled when a session opens, search across earlier sessions, and skills a session writes for the next one — kept locally, or in Synapse.
Multiply yourself
Delegate durable subagent runs, leave them working in the background, and switch among their transcripts without leaving the main terminal.
Extend carefully
Import the tool servers your other tools already have, then add skills, prompts, and capability-scoped plugins with content-pinned approval.
Embed the engine
Interactive TUI, one-shot prompts, JSON streams, JSON-RPC, or your own Rust host. The core runs without the terminal and lets you choose which plugin runtimes to include. Embedding guide.
Edit like a shell
Walk earlier prompts with Up and Down, edit by word or line, and add a newline with Shift+Enter. @ completes a path, and Esc Esc rewinds to the last one.
Decide once
A permission prompt shows a diff for an edit, or the command for a shell call, and takes y, n, or a to keep the decision for the rest of the run.
Hook the session
A command can run at a session's start, before or after any tool call, and when it ends — a pre_tool hook can block the call outright.
Connect every tool
ainz synapse connect links both products in one step. Synapse shares Ainz's memory, guidance, and skills with your other tools; --mesh gives every subagent its own visible seat.
No model configured? Just run
ainz. The setup screen lists providers and pulls their models straight from each endpoint — no config file, no typing a model name by hand.
