There’s a pattern most AI-assisted developers know well. You prompt Cursor or Claude, get back 80 lines of working code in seconds, merge it, and move on. Then three weeks later, a bug surfaces in that exact block and you have no idea how any of it actually works. The code ships fast. The understanding doesn’t.
That’s the specific problem Unvibe is built to fix. It’s a Mac desktop app that sits beside the tools you already use and turns code review into an active learning loop. You highlight code, press ⌘U, and get a focused explanation pitched at your level, right where you’re working, without switching tabs or losing context.
The idea is deceptively simple. But the execution is more thoughtful than most “AI explains your code” tools. Unvibe doesn’t just answer one question and forget it. It saves what you’ve learned and brings it back through spaced repetition, so the knowledge actually sticks over time.
Key Features of Unvibe
On-the-Spot Code Explanations
Select any block of code in Cursor or VS Code, press ⌘U, and an explanation appears immediately beside your work. You can choose your depth level: New, Beginner, Intermediate, Advanced, or Expert. The explanation is pitched to where you actually are, not a generic overview. Beta testers noted the depth controls make learning feel genuinely tailored to the individual.
Active Recall and Spaced Study Queue
Every explanation you save gets added to a study queue. Unvibe surfaces those concepts again later through active recall, the same technique used in spaced repetition flashcard apps. This is what separates it from a simple “ask AI about my code” workflow. You’re not just reading an answer once. You’re building memory that compounds across your whole project.
Git Diff and Agent Change Briefs (Pro)
On the Pro plan, Unvibe goes beyond individual code selections. You can get explanations for entire git diffs, agent change briefs summarizing what an AI coding agent just did, nearby-file context, and since-last-understood compares. This matters a lot if you’re using Claude Code or Cursor agents to make sweeping changes across multiple files at once.
Local Secret Filtering
Before anything leaves your machine, Unvibe scans the selected code for secrets on-device. Environment variables, API keys, and build output are excluded by default. You can also add custom rules via a .unvibeignore file. The cloud analysis only happens after that local filter runs, which is a sensible privacy default for anyone working on real projects.
Marcus at 11pm, Debugging Code He Didn’t Write
Marcus Reyes is a freelance developer based in Austin. At 11:14pm on a Tuesday, he was trying to fix a broken authentication flow in a Next.js app. Most of the auth logic had been generated by Cursor three weeks earlier. He remembered accepting the diff but not reading it carefully. Now a session token wasn’t refreshing correctly and he had no idea why the original function was structured the way it was.
He highlighted the 20-line token refresh handler, pressed ⌘U, and set the depth to Intermediate. Unvibe’s floating panel appeared beside VS Code and walked him through exactly what the function was doing: how it checked for token expiry, why the conditional was structured that way, and where the refresh call was being triggered. It took about 90 seconds to read.
He hit “Got it” and saved the explanation. He found the bug (a missing await on the refresh call) within two minutes of finishing the review. The whole session, from confusion to fix, took under 15 minutes. A week later, Unvibe surfaced that same token logic in his study queue. This time he answered the recall prompt correctly without needing to re-read a thing.
How Unvibe Fits Into Your Workflow
Step 1: Install and Allow Accessibility
Download the Mac app, move it to Applications, and open it once so macOS registers the global keyboard shortcut. You’ll be prompted to allow Accessibility access, which is how Unvibe reads the code you’ve actively selected in any application.
Step 2: Select Code and Press ⌘U
Highlight any block of code in Cursor, VS Code, or another supported tool. Press ⌘U. Unvibe’s floating Island panel appears with a fresh explanation. No tab switching. No separate chat window.
Step 3: Review, Test, and Save
Read the explanation at your chosen depth. You can ask a follow-up question, request a different explanation style, or hit “Test Me” to immediately check your understanding with a quick quiz. Save the concept to your queue and continue building.
Pricing
Unvibe offers a free tier and a paid Pro plan. Here’s what each includes:
- Free ($0, no card required): 50 explanations per month, selected-code explanations, core depth levels, spaced study queue, and saved progress.
- Pro ($8/month or $72/year): 100 explanations per month, git diff explanations, agent change briefs, nearby-file context, since-last-understood compares, and Expert depth level.
Pricing is still being validated during the private beta, and Unvibe says you’ll always see the final price before any paid plan begins. The free tier is genuinely usable for solo projects and learning workflows.
Worth Trying If You Build with AI
Unvibe is a focused tool for a real problem. If you regularly accept AI-generated code without fully understanding it, this fills a gap that no amount of prompting a chatbot in a separate tab actually solves. It’s currently in private beta for Mac, with Cursor and VS Code validated. JetBrains and other workflows are being tested. Request access or download the beta directly at unvibe.site.
