Selected codejavascriptfunction debounce(fn, wait) { let timer; return (...args) => {

debounce wraps a function fn so it only runs after calls stop for wait milliseconds.

Each call cancels the pending timer with clearTimeout and starts a new one with setTimeout. So if calls keep coming quickly, fn waits, then runs once with the most recent args.

Useful for search boxes, where you only want to react after someone stops typing.

clearTimeout on line 4 cancels the call scheduled by the previous invocation, and setTimeout on line 5 schedules a new one. Together they restart the countdown on every call.

That restart is what makes this a debounce: fn runs only after wait ms pass with no further calls.

Selected codejavascriptfunction debounce(fn, wait) { let timer; return (...args) => {

debounce wraps a function fn so it only runs after calls stop for wait milliseconds.

Each call cancels the pending timer with clearTimeout and starts a new one with setTimeout. So if calls keep coming quickly, fn waits, then runs once with the most recent args.

Useful for search boxes, where you only want to react after someone stops typing.

clearTimeout on line 4 cancels the call scheduled by the previous invocation, and setTimeout on line 5 schedules a new one. Together they restart the countdown on every call.

That restart is what makes this a debounce: fn runs only after wait ms pass with no further calls.

Test me

Calls arrive 50 ms apart and wait is 300 ms. When does fn run?

A✓On the first call

B✓Every 300 ms while the calls continue

C✓Once, 300 ms after the last call

D✓Never, the timer keeps resetting

(FAQ)

Short answers.

Every question and answer

A free desktop app for Mac and Windows. Select code in any app and press Control+U (Ctrl+Alt+U on Windows). A panel beside your editor explains it at the depth you pick. Ask follow-ups, check yourself with Test me (up to 3 questions about that code), and save the lesson to your Library. The Today page sets a small daily goal: explain one piece of code and answer one question.

Any app where you can select code: Cursor, VS Code, Xcode, Terminal, your browser and more. In Cursor and VS Code, an optional editor bridge adds ⌘U (Ctrl+U on Windows).

Only what you ask about: the selected code and its language, the file's path inside your project when Unvibe knows which file it came from (like src/lib/retry.ts), and the name of the project folder you last worked in with Unvibe. With Pro, some nearby code is added for context, and Briefs send the git changes you ask the AI to explain. Any question you type is sent too. Unvibe checks the code for keys and tokens on your computer first, and from version 0.1.44 your questions and Ask Vibe chat messages too. A known key stops the request. Your repo is never uploaded. If you add your own API key in Settings, the app sends the request straight to that provider instead.

Yes. New, Beginner, Intermediate and Advanced are free. Expert is part of Pro. Switch any time and the same code is explained again at that depth.

Yes. Free covers explanations at New through Advanced, follow-ups, Test me and your Library: 50 explanations in your first 30 days without signing in, then 50 explanations a month when you sign in. Briefs of your Git changes and “Why does this exist?” are free too and run on your computer. No card and no API key.

Yes. Download the .exe from the Download page, or paste irm https://unvibe.site/install.ps1 | iex into PowerShell. The app isn't signed yet, so SmartScreen may warn the first time. Then select code in any app and press Ctrl+Alt+U.

Yes. AI can be wrong even when it sounds sure. Each explanation sits next to the code it describes so you can check it, and Test me helps you spot what doesn't add up.
