Free forever
Your agent's own interface, full height, exactly as it draws itself — with a writing bar underneath it. One truth on screen, and a comfortable place to answer it.
Version 0.2.2 · macOS 15+ · Apple Silicon & Intel · Signed & notarized · updates itself
The Input Bar
Under the terminal sits the bar you write from — and around what you write, the state you keep glancing up for: the branch with the number of files you've changed, the model, how long this turn has been running, and the permission mode.
The permission chip says what your agent says — its own wording, never ours — coloured by what it means rather than how it's spelled. Click it to cycle the mode. It appears only when the mode is actually known, and dims when it's merely inferred.
⌘J is progressive: focus the bar, hide it, bring it back, with a glow on the edge saying which state you're in. The terminal stays fully usable either way — click it, arrow through its menus, or just type straight into it with the bar closed.
Any agent
Claude Code, Codex, Antigravity, Kimi, Grok, and open-source agents that talk to models on your own machine — pick per session and run them side by side. Anything missing installs itself on first start.
The catalog arrives over the air as a signed snapshot, so when an agent ships a new flag, a new model list or a new name, it reaches you without waiting for an app update. Anything that fails its signature is ignored and the app keeps the list it already trusts.
Gemini CLI is listed as API key only — individual Google sign-in was discontinued, and Google's own successor, Antigravity CLI, is in the catalog too.

Your own CLI
Add any command as an agent and it appears in the picker beside the built-in ones, with a name and a mark of your choosing. It runs through your login shell in the session's folder, so pipelines, quotes and shell functions all work.

Runs in the terminal, not on your phone
Your agent works here exactly like the built-in ones. What it can't do yet is appear as a chat in BoxDo on your phone.
Record a support session
So we can build the chat mirror for Aider
The prompt
Read notes.txt, then append a line saying 'reviewed' to it, then run 'wc -l notes.txt'…
An agent of your own runs here, but it can't appear as a chat on your phone yet — that needs code written against a real recording. So there's a button for it: one short exercise in a throwaway folder, every path rewritten, keys and addresses stripped, and a bundle you read before you send it.
One drawing of one truth
BoxDo Terminal used to draw its own chat next to the terminal your agent was already drawing. Two pictures of one conversation can quietly disagree — a line missing on one side, a different order on the other, and nothing to tell you which was right. So the terminal won. What the chat was genuinely better at, writing comfortably, moved into the bar below it.
So a session is four things: a window, your agent's own text, the files it touched, and somewhere to write back.
Ten agents, one app
Identity
Every project gets a colour and wears it. A strip above the field carries the project's name, and that colour runs through the field, the send button and the palette — so you always know which codebase you just told to delete something.
Dress it from the strip: ten Looks, painted or photographic backgrounds, a watermark, an emoji, a pattern, and a rename for the project itself. Hovering a Look tries it on the real bar before you commit to it.
Looks
Files
Files your agent just wrote show up as chips between the terminal and the bar — created told apart from modified, and the files it only pointed at in an answer alongside them, images carrying a thumbnail.
Each one is draggable, so dropping it in Finder copies it and dropping it in a mail composer attaches it. Or Quick Look it, open it, reveal it, or hand it back to your agent as context.
The Studio · ⌘S
⌘S lays a sheet of paper over the session: one column, the sentence you're writing lit, the rest stepped back, and the line holding its width at every text size.
Type @ to reach a file by name or drag one in from the tree, watch the word count, and send with ⌘↩. It's the same draft as the bar, so esc returns to it with your text intact.
Bookmark a prompt worth keeping and it comes back as a /command in any session.
Type @ and a few letters. Ranked matches over the whole project, the plain path inserted — nothing to quote or escape.
⌘F searches the scrollback, which keeps 5,000 lines. Step through matches with the arrows, close with esc.
Reading and copying
⇧⌘C copies your agent's last response as plain text — read from the transcript, not scraped off the screen, so nothing arrives wrapped or truncated.
⌥⌘C enters copy-mode: pick a spot, extend the selection from the keyboard, copy. It drives the terminal's own selection, so it will also pick up and extend one you started with the mouse.
Mission control
The session list reads like an inbox: every session shows its last exchange squeezed into one line — or You: … when your agent is the one waiting on you. ⇧⌘D opens the same picture across every project, sorted by who needs you, who's working, who's done.

Privacy
Diagnostics are off until you turn them on. Two columns spell out what would be sent and what never is — and View Recent Events shows you the actual lines rather than asking you to trust the description.
Export Diagnostics writes a sanitized bundle you can read before you share it. What you and your agent wrote, terminal output, file paths and folder names are never collected at all.
One thing is on by default — which agents you have installed and how many sessions each has, never a name or a path. It has its own switch on the same pane.

Themes
Ten themes, each in a dark and a light variant, applied to the whole app — terminal palette included. Fine-tune any of them and save the result as a theme of your own.
The app costs nothing, and it will stay that way.
Developer ID, checked by Apple. No warnings, ever.
Checked once a day. New versions install and relaunch on their own.
⌘K palette, rebindable shortcuts, everything reachable without the mouse.
