Three steps. Under 10 seconds.

1

Click CodeRa

Open the extension on any page. Pick your mode — text, code, or understand.

Hit Capture Video Frame on YouTube or Udemy. Or drag over any code. Or upload a screenshot.

3

Paste anywhere

Code lands in your clipboard. Review in the result panel. Ctrl+V into your editor.

// three AI modes

One click. Three ways to use it.

📄
Default mode

Plain text

Extracts everything visible — subtitles, slide text, captions, UI labels. Exactly as shown, nothing rewritten.

🧠
Understand code

Learn & trace

Claude explains what the snippet does, traces execution line by line, shows expected output. Learn the logic.

"I was retyping code from Udemy for years. One click and I'm done. Wish I had this sooner."

— Frontend dev, Udemy learner

"The code extraction is surprisingly accurate — even preserves my tabs. Finally something that actually works."

— Backend engineer, Python learner

"The Understand mode is what sold me. I don't just copy anymore — I get what the snippet does before I paste it."

— CS student, self-taught dev
// vs alternatives

Why not just use OCR or ChatGPT?

Tool The problem CodeRa wins because
Apple Live Text / Google Lens Destroys indentation, confuses { } => ; Understands syntax — preserves formatting
ChatGPT / Claude.ai 5+ steps: screenshot → save → upload → prompt → copy 1 click, prompts built in, auto-copy
Blackbox / OCR extensions Old models, can't capture video frames Claude Vision + video frame capture

Quick answers

Is it really free?
Yes — completely free during early access. All features unlocked. No account, no credit card.
Is it safe to use at work?
Yes. Screenshots are processed and immediately discarded — nothing stored on any server. Same privacy as typing into Claude directly. Safe for proprietary code.
Does it work on YouTube and Udemy?
Yes. Click Capture Video Frame on any course site — grabs the current frame while the video keeps playing. Works on YouTube, Udemy, Coursera, Skillshare, and any embedded player.
What's the difference between the three modes?
Plain text — extracts everything as-is (subtitles, slides). Extract as code — IDE-ready formatted source. Understand code — Claude explains the logic and shows expected output, built for learning.
Who built CodeRa?
Built by Anton Zakharenka — a developer who got tired of retyping code from tutorials. Not developed by Anthropic.

Stay in the loop

Early access updates — no spam, one email.

Stop retyping.
Start extracting.

Every developer rewatches tutorials to retype code. You don't have to.
