Highlights in 0.18.0
  • • A memory you can read and correct — a new You page shows what Mugi kept, in your own words, with Fix and Forget on every line
  • • Only what you said is kept — background guesswork no longer files facts about you; anything half-known comes back as a question
  • • Secrets never reach the model — a number you ask Mugi to keep goes to your Mac’s Keychain, with one Touch ID each time it is used
  • • The engine picker names your engine — mlx-serve, oMLX, Exo, or an External API, with what each one can load said up front
What's included
  • • Native SwiftUI macOS app
  • • Local models via mlx-serve (installed for you)
  • • Sparkle auto-update support
  • • Vault, Knowledge Base, You pane, global Dashboard (⇧⌥D), etc.

Changelog

Every public beta, newest first — the short version. The full notes for a release are what Sparkle showed when it offered the update.

0.18.0 October 2026
  • • Mugi remembers you, and you can see it — the You page shows what it kept, in your own words; correct or forget any line
  • • Only what you said gets kept — background noticing no longer files facts about you, and half-known things come back as questions
  • • Secrets stay out of the model — numbers you ask Mugi to keep go to your Mac’s Keychain, one Touch ID each time
  • • Forget means forget — forgetting something also hides it when it returns in different words
  • • One place to choose your engine — the picker names each engine (mlx-serve, oMLX, Exo, External API) and says what it can load
  • • Come back to your conversation — relaunching returns you where you left off, and Stop keeps the reply you already read
0.17.0 September 16, 2026
  • • Local chat runs on mlx-serve — a small engine Mugi installs for you; no Python model server to set up
  • • Plain sentences when something goes wrong — a model that will not load gets an explanation, not a server log
  • • A new encoder for Library search — older libraries need a one-time re-index
  • • macOS 26.2 or later is now required — the Train and Adapters controls are hidden; this engine does not use chat adapters
0.16.0 September 9, 2026
  • • Folders in the Library — add, move, reading order; originals stay on disk
  • • Change a document where it lives — Word, Excel, PowerPoint, or PDF; a staged copy, then one approval
  • • Chat knows what’s on screen — an open Vault note, Results page, or Library document is what “add a line here” means
  • • Follow-up turns stay fast — the tool list no longer grows mid-thread
0.15.1.1 September 5, 2026
  • • Automatic updates actually run — the update check happens after the chat window is on screen
0.15.1 September 5, 2026
  • • The right tools for the question — asking about your Mac, your notes, or a long recording no longer starts from a blank shell
  • • Long answers are kept — the rest of a result is no longer thrown away mid-sentence
0.15.0.1 September 4, 2026
  • • Fixes for three bad failures — a reply that doubled itself, jobs that could not be deleted, and a “report only” job that received every tool
0.15.0 September 3, 2026
  • • Sort out this Mac — ask in ordinary language; it asks before changing anything, in words, and keeps a list you can undo
  • • Look it up instead of recalling it — a question you would not want to get wrong comes back with sources
  • • A long page comes back as a map — the whole document stays on disk; Mugi queries the part it needs

Releases before 0.15.0 are covered in about this preview.
