Squirrl home: the orb, a Today card, and the mic prompt

A studio's day is mostly admin nobody wants to click through.

Client notes, meeting follow-ups, files and calendar live in five tools. We built Squirrl for ourselves first: a single orb you talk to that knows every client, can read every doc and acts (schedules, files, drafts) with a human approving anything that leaves the building.

  • ProblemContext scattered across five tools, re-typed daily
  • BetVoice plus agents beats another dashboard
  • ConstraintNothing sent or deleted without a human in the loop

What we built.

Squirrl in four parts, the pieces that carried the product, in the order we shipped them.

  1. (01)

    The orb

    Push-to-talk voice surface with streaming transcription; the whole interface is one conversation with memory per client.

  2. (02)

    Agent + tools

    Claude with MCP tools over calendar, docs, mail and CRM. Every write action is proposed first, executed on approval.

  3. (03)

    Client memory

    Per-client context built from notes, threads and docs, retrieved on demand, never stuffed into one prompt.

  4. (04)

    Quiet UI

    Cards for today, recent clients and documents surface only when relevant, the screen earns attention, it doesn't demand it.

/ ScreensAs shipped
Printed flow: Clients → client detail → Calendar
One flow: Clients, a client's board, the calendar it writes to
Designare client board with To do and Doing tasks
A client board: Designare, tasks and deliverables, kept by the agent

What it did.
