01 — What's inside

One window.
Every study tool.

The 0.3.5 beta brings a Cloud Drive, PDF Chat, flashcards and a forum into the same calm sidebar — next to the browser, AI and calculator you already use.

AI chat, with your files

Model picker, DeepThink, web search and attachments — with a free starter balance and every conversation saved.

Cloud Drive, built in

680 MB free, 32 GB with Pro. Folders, previews, a storage meter, and Save to Drive from any tool.

Turnitin-style check

Full Wikipedia matching, so a copied passage scores the way it should — sources highlighted, line by line.

UHHHelper

A floating helper that scans any app you're in, then summarises, translates, explains or cites it.

Friends & forum

DMs, group chats and file sharing — plus subject forums with replies and real moderation.

TI-84 calculator

The full scientific keypad, a graphing mode, zoom presets and auto-range. No second window, no phone.

Flashcards, calendar, GPA

Spaced repetition, a real calendar, a GPA calculator, assignments and a focus timer — one study loop.

PDF Chat

Drop in a reading, ask questions, and get answers with the exact passage attached.

Themes & motion

Ocean accent, free and Pro palettes, the theme marketplace, smooth motion and seasonal touches.

Academic mode

One switch turns UHH into UAH: monochrome, chat hidden, risky tools off — locked for an hour.

02 — What's new in 0.3.0

Cheaper to run.
Smarter about you.

AI credit is now measured in ¥ with a cost preview before every action, the assistant remembers your courses and notes, the browser has a real homepage, and startup is ~6× lighter.

1.0

Playtesting with real students, then stability, polish and a custom domain.

See the features
What changed0.3.0 · Oct 2026
  1. 01

    Credit in ¥

    ¥2 buys a million tokens. Every action shows its cost first — AI ≈ ¥0.002, grammar ≈ ¥0.003.

  2. 02

    AI that remembers

    Your courses, recent notes and weak flashcards go into the prompt, with a Patient / Funny / Socratic / Strict tutor style.

  3. 03

    Browser homepage

    New tabs open on a real start page: search, quick links, resume cards and bookmarks.

  4. 04

    Pro in ¥

    ¥48/month or ¥480/year, ¥32 of AI credit included, 32 GB of storage, paid through AfDian.

  5. 05

    Six times lighter

    Startup payload dropped 84% — heavy tools load only when you open them.

03 — First launch

Opening it
the first time.

UHH isn't notarized by Apple yet, so macOS may warn you the first time — or even call it malware. It's a false alarm. Here's the one-time fix.

  1. 1
    Open the downloaded UHH-0.3.5-arm64.dmg and drag UHH into Applications.
  2. 2
    Double-click UHH. If macOS says it can't verify the app, close that dialog.
  3. 3
    Open System Settings → Privacy & Security and scroll to the bottom.
  4. 4
    Next to “UHH was blocked”, click Open Anyway, then confirm with Touch ID or your password.
  5. 5
    Done — UHH opens normally from now on. This is a one-time step.

Updates install themselves after this. No repeat visits, no terminal.

04 — Download

Ready when
you are.

One download, one drag, one first-launch step. Then every tool is waiting in the same window.
