Deep focus,
enforced.

FocusForge blocks the apps and websites that break your concentration for the length of a study session. It includes a study tutor that runs on your own machine, so your notes never leave your computer.

What's included

Session blocking

Pick the apps and sites you're allowed to use. Everything else is closed for the length of the session. Overrides are limited and recorded.

Study tutor

Runs locally on your machine. Explains concepts, writes practice questions, and reads problems from a screenshot. It searches the web only when a question needs current information, and cites what it used.

Spaced repetition

Turn notes into a deck in one step. Cards come back on an SM-2 schedule, so you review each one shortly before you would have forgotten it.

Session history

Focus time, completion rate, streaks, and which distractions you reach for most often and at what hour.

Browser extension

Applies the block list at the tab level and adds highlight-to-explain: select text on any page and the tutor explains it in place.

iPhone companion

Uses Apple's Screen Time framework to lock your phone for the same session, with the same list of approved sites.

How it works

Three steps

  1. 1

    Set the rules

    Choose approved apps and study sites, then set your study and break lengths. Save the configuration as a template to reuse.

  2. 2

    Start the session

    Anything outside the list is blocked until the timer ends. Breaks lift the restrictions automatically, then reapply them.

  3. 3

    Review

    Breaks can quiz you on what you just covered. Finished sessions feed your history and flashcard schedule.

The tutor

Answers it can actually support

The tutor decides on its own whether a question needs outside information. For settled material it answers directly. For anything current or specific it searches first and answers from what it found, rather than filling the gap from memory.

  • Runs on your machine; material stays local
  • Optional guardrails keep it on your subject
  • Reads screenshots of problems and diagrams
  • Save any answer as a flashcard

FAQ

Common questions

Where is my data stored?

On your computer. Sessions, notes and flashcards are kept locally, and the tutor's model runs on your own machine rather than a hosted service.

Can I get around the blocking?

You get a small number of overrides per day. Each one is recorded and reduces your focus score. Hardcore mode removes overrides until the session ends.

Does it work offline?

Blocking, flashcards and history work without a connection. The tutor needs its local model running; web search is optional and requires internet.

What are the system requirements?

Windows 10 or later, or macOS 12 or later. The tutor's local model performs best with 16 GB of RAM or a dedicated GPU.

Is there a mobile app?

An iPhone companion app is in development. Android is planned after it ships.
