Smithers· the multi app

Smithers / multi

A home for your
coding agents.

Chat to build. Watch the work happen live. Review every change, rewind any run, and pair with teammates and an AI in the same room — all in one app you can open anonymously and deploy to the edge.

Just say what you want built.

No dashboards to learn. One calm prompt: “Ask Smithers to build…”. Pick a model, talk or type, and go. The whole control plane unfolds from this one line.

Smithers home — the build composer
One composer, every mode

One line in. A live workspace out.

Type a slash command and a card appears in the chat; click it and the matching surface slides in beside you. Chat, Store, Concierge — the same box switches modes as you work.

See the work

Watch every step, as it happens.

A live run tree shows the agent planning, editing files, and queuing tests in real time. Open any node to read its exact prompt, tool calls, and props — nothing is a black box.

Review

See exactly what changed.

Every run produces a real, syntax-highlighted diff — file by file, additions and deletions counted, new and deleted files flagged. Review the agent’s work like a teammate’s pull request.

Time travel

Rewind, replay, or fork any run.

Scrub a run’s snapshots like a video. Jump back to any frame, hit Replay, or Fork from here to try a different path — without losing the original. Approval gates are marked right on the track.

Nothing ships without your say-so.

Agents pause at the gates you set and wait. Approve, deny, or cancel from one review inbox — human-in-the-loop is a first-class surface, not an afterthought.

Model-agnostic

Bring any model.

Smithers isn’t tied to one provider. Register agents on Codex, Gemini, Kimi and more — drive them from your own subscriptions and route each task to the right brain for the job.

Smithers Pair

Build together — with an AI in the room.

A shared workspace where two people and one model edit the same document live. Every keystroke and cursor syncs instantly; prompt the shared AI and its reply lands in everyone’s console and the doc.

Realtime, by default

Presence, cursors, and a shared brain.

See who’s online, follow their cursors, and browse the real repo file tree together. Flip on “collaborate on one prompt” and you co-author a single request to the model — synced to every collaborator over ElectricSQL.

Find anything. Instantly.

One palette for files, commands, slash actions, and “ask AI”. Fuzzy-search your way to any surface or action without lifting your hands off the keyboard.

Workflow Store

A store of ready-to-run workflows.

Install reusable workflows and drop into a guided task in one click. The catalog is the live set registered on your gateway — launch any of them straight from the composer.

Concierge

Turn a rough idea into a real plan.

Describe a task in plain words and the concierge builds a context contract — goal, scope, non-goals, open questions — then routes it to the right workflow once the readiness checks pass.

And a surface for everything else.
