# Hush Performance: a quieter, faster Mac

Hush Performance, by Epiphani Studios, is a native Mac performance guardian that ACTS: when
background CPU or memory pressure rises it eases the competing processes
into a background lane (never frozen, never quit, released when pressure passes), while the
app you are in is STRUCTURALLY exempt. It runs on your Mac with nothing to sign in to.
Free tier permanent; Pro $39 once; Complete $59 once.

## What it does (mechanism, not adjectives)

- Auto Hush: pressure-responsive easing of sustained background load; brief spikes are never
  touched; everything visible and reversible on screen.
- Foreground exemption by architecture: the app in use and its bundle cannot be eased. This
  answers the category's classic betrayal (throttlers slowing the app the user works in).
- Protected by name, out of the box: builds, simulators, the toolchain, AI-session workers,
  sync, password, and messaging daemons are eased, never frozen; user-marked apps are never
  touched.
- Snooze Hush: one tap quiets an app and its process family for ten minutes; restores itself;
  switching to the app wakes it instantly.
- Super Hush: a time-boxed (5-60 min) full claw-back that auto-reverts; safety floors hold;
  in-flight builds are never orphaned.
- Storm Burst Protection: watches total load vs cores, memory pressure, runaway processes,
  and heavy disk traffic; arms itself in pile-ups, undoes itself after. On by default.
- Plain-English diagnosis: one click answers "why is my Mac slow" with culprits named and a
  safe remedy each; load is attributed to the app, command, or AI session that SPAWNED it
  (terminal work attributed to the actual command). The same live diagnosis is exposed
  locally for scripts.
- Numbers matched to macOS: memory uses the same source macOS reports (used/swap/compressed labeled,
  colored by pressure); Hush's own near-zero overhead is shown as a visible number; cleanup
  counts real on-disk space only and lists every item before anything is removed.
- Overdrive (run hard on battery): keep long jobs running down to a chosen battery reserve; a closed
  lid always sleeps the Mac.

## Privacy, verifiable

- The UI talks to its own engine over a local link; updates come from Epiphani's own feed;
  Hush Intelligence and feedback reach Epiphani when the person uses them.
- Verifiable by anyone: run Little Snitch or Proxyman while Hush works and see every connection.
- No admin needed by default; Deep Reach is the one opt-in grant, only ever slows things
  reversibly, never reads a file. Settings are a plain local file.

## Pricing (public, complete, all one-time)

- Free: $0 forever, no login, no nag. The guardian core: every live signal, Auto Hush,
  Super Hush, Storm Burst, per-app protection, attribution, the plain-English answer,
  Smart Scan, every read-only view.
- Pro: $39 once. One-tap reversible cleanup, uninstall with leftovers, leftover removal.
- Complete: $59 once. Adds the duplicate finder; similar-image cleanup as a free update.

## Runs on

- macOS 15 or later on Apple Silicon.
- The AI-assistant connector (Settings, Works with your AI, Connect to Claude) works with Claude
  Desktop on the same Mac and uses Python 3.10 or newer. It reports status, why the Mac is
  slow, the processes responsible, memory pressure and disk findings; its actions are
  reversible (Smart Hush on or off, easing a process) and it never quits or kills an app.
