PUBLIC PREVIEW — JULY 2026

A local Mac agent that gets things done In an app, not a terminal.

Open-source models on your Mac — searches the web, reads and writes files, runs tools, and delegates real work to background workers.

A native Mac app: chat, notes, Settings, and a first-run wizard — not something you assemble from the command line. Your mother could use it; power users still get Kanban, Vault, and every toggle in Settings.

Private by default — no telemetry, no cloud account. Everything stays on disk under your control.

Swap in any model you like — we recommend a few that work great out of the box, but you're not locked in.*

Cloud AI is fast because it's someone else's computer. Mugi is fast on yours.

Mugi runs entirely on your Mac — MLX inference, your workspace, your files. It looks and behaves like the Mac apps you already use: a main window with conversations, an Activity feed, Preferences panes, and voice input — not a developer tool disguised as chat.

Every conversation, note, and memory file lives on disk you control. Nothing is uploaded. Nothing is collected. You review, edit, export, or delete on your terms.

It maintains a working model of you (goals, commitments, recurring threads) and uses it to surface useful background work — always as reviewable proposals or Kanban tasks that wait for your go-ahead.

A real Mac app
Download, drag to Applications, launch — the wizard picks your model and you’re talking. Signed, notarized, Sparkle updates.
Your hardware, your model
Recommended MLX models ship ready to go. Point Mugi at any compatible model — though not every one works equally well on first try.
Your data stays yours
Conversations, notes, and memory files live in your workspace. No cloud sync, no telemetry, no collection.
You stay in control
Background work surfaces as reviewable proposals and Kanban tasks — nothing mutates silently. Accept, reject, or correct anything.
SINCE 0.10.1

Your Mac, at a glance

Press ⇧⌥D from anywhere — a floating panel with live vitals, your calendar, weather, markets, news, and a dedicated agent chat that already knows what’s on screen.

  • CPU, GPU, RAM, disk, and network throughput — updated live
  • Upcoming events from every calendar you’ve shared with Mugi — click to open in your default app
  • Weather hero, market tickers, and RSS news you can customize
  • “What should we do next?” — quick actions and a composer wired to the agent loop

View → Dashboard in the menu · Esc to dismiss · Same privacy as the rest of Mugi — all local.

Mugi global Dashboard panel — system vitals, calendar, weather, markets, news, and agent chat

An agent that gets things done

Under the friendly UI, a real agent loop: the model calls tools, Mugi runs them on your Mac, feeds results back, and keeps going until the job lands — or it needs you.

Files & workspace

Read, write, patch, search, and organize files in your workspace — plus git status and commits when you need them.

Web & research

Local search, page capture, deep multi-source research — Research mode spins a background worker so long investigations don’t block chat.

Documents & OCR

Extract text from PDFs, OCR scans and photos, split and merge documents — without leaving the app.

Work execution

In-thread task plans, durable Kanban workers, Results deliverables — serious multi-step work, not just chat replies.

Memory & knowledge

Persistent memory, a dedicated Vault notebook with hybrid search, and a Knowledge Library you browse, read, and graph — with citations when Mugi draws on what you’ve studied.

Mac & system

Global Dashboard (⇧⌥D) with vitals, calendar, weather, and news; Spotlight search and host diagnostics — optional shell when you explicitly allow it.

Voice & media

Voice input, text-to-speech, and Full Duplex voice (beta) — talk to Mugi like any other Mac app with a mic button.

Extensible

Skills, plugins, and MCP servers add more tools without rebuilding the app — power without turning it into a dev project.

Risky bits (shell, web automation, background autonomy) stay behind explicit Settings toggles and your approval.

Remembers you. Waits for your OK.

Consent-first memory and background work — the parts that make Mugi more than a chat window.

Remembers your context — on your machine

Mugi builds a working model of your projects, preferences, and commitments — stored locally, never uploaded. Background processes extract signals from conversations and notes; they surface as reviewable proposals in the You pane or concrete tasks in Kanban, always waiting for your approval.

  • • Protected personality files (agent can't silently rewrite your identity)
  • • You pane with live diffs, provenance, and accept/reject
  • • Connections journal and pattern observations
  • • Checkpoints so you have a clear record of what it has learned

Vault — your private notebook

Vault now has its own front door in the sidebar: write, organize, and find notes without triage-inbox chrome in the way. Hybrid search (full-text + semantic recall), a related-note inspector, wikilinks, and a recently-deleted list — still encrypted at rest, still on your Mac.

  • • Dedicated Vault workspace with projects sidebar and rich note editor
  • • Hybrid search so older notes are findable, not just the most recent
  • • Related inspector — neighbors and links beside the note you’re reading
  • • Wikilinks, voice memos, attachments, and “Discuss this” into chat
  • • On my mind stays separate — triage queue vs. library you keep
Shipped in 0.11.0 (July 2026). Notes you had before are unchanged — only navigation moved.

Knowledge Library — study surfaces that keep getting better

Feed Mugi folders, documents, codebases, or research collections. The Library is now one continuous workspace — search, reader, inspector, and graph — instead of a pile of subsystem tabs. Source repair, corpus rename, and clearer ingest status landed in 0.11.0.

  • • Unified library workspace + Connections explorer and graph mode
  • • Reader typography controls, source editing, and first-run onboarding
  • • Hybrid search + “Ask the corpus” with citations
  • • Study chat attachments in Knowledge (with your consent)
  • • Trust summary in Activity — manifest health, index drift, reconcile
July 2026 progress

0.11.0 is a big step for the surfaces people live in daily: Vault as its own notebook, Knowledge as a proper library, and a completed kernel cutover so chat and workers share one reliable stack. We’re still in public preview — but the direction is clearer and the rough edges are fewer.

See Settings → Knowledge and the in-app Library for corpus admin, progress, and search.

PUBLIC PREVIEW

This is an early public preview

Not a finished product. A serious attempt at something new, released so real people can tell us if the direction is worth pursuing.

What’s working well

  • • 0.11.0 (July 2026) — Vault as its own notebook; Knowledge Library workspace; kernel cutover complete
  • • Global Dashboard panel — vitals, calendar, weather, markets, news, and agent chat (⇧⌥D)
  • • Native Mac experience with thoughtful surfaces and a first-run wizard
  • • Protected personality files + strong write guards on the User Model store
  • • “You” pane for reviewing what the background has learned
  • • Consent-first background autonomy (Kanban, proposals, Activity)
  • • Vault hybrid search, related inspector, wikilinks, and recently deleted
  • • Knowledge graph, source repair, study-in-Knowledge attachments, trust health
  • • Steady reliability work — migrations, release gates, and fewer silent failures

What’s still early

  • • The background memory system is powerful but new — feedback still shapes it heavily
  • • Not every MLX model works out of the box — recommended models are the smoothest path
  • • Vault semantic search warms up in the background after large notebook upgrades
  • • Very large Knowledge digests remain async — progress and trust health help, but patience still matters
  • • Not every advanced flow is polished end-to-end
  • • Messaging adapters (e.g. Telegram) are not built yet — voice input, TTS, and Full Duplex voice mode (beta) are in the app today
  • • First public release from a solo developer — thank you for bearing with the preview
