async function verifyToken(token) { try { const decoded = jwt.verify( token, process.env.SECRET ); return { valid: true, decoded }; } catch (err) { return { valid: false }; } }
This function checks whether a login token is genuine. If valid, it returns the user's info. If fake or expired, it returns "invalid" — so the app can block access.
Protects your app from unauthorized access. This is your authentication gate.
Error is silently swallowed — failed logins aren't logged. Ask your dev to add monitoring.
No learning curve. No setup. Just answers.
Highlight any code snippet, error message, or PR diff on any webpage — GitHub, GitLab, Jira, Confluence, anywhere.
Open CodeBabel from the context menu, or hit the keyboard shortcut. Pick your language and audience mode.
Instant, structured explanation — summary, step-by-step breakdown, red flags, and a follow-up Q&A in your chosen language.
Not just a translator. A full code comprehension layer for non-technical people.
What does this code actually do? Explained in one paragraph, jargon-free, as if you asked a brilliant friend.
Each logical block explained in sequence — so you can follow the flow of the code from start to finish.
For devs who want full depth — algorithms, patterns, complexity, and implementation notes. Toggle on demand.

"This is a function that acts like a security guard at a club. It checks your ID (the token). If your ID is real, you get in and it remembers who you are. If it's fake or expired, you're turned away."
"This is the login verification system. It protects user accounts. There's a potential risk — failed logins aren't being tracked. That means you can't detect brute-force attacks. Worth raising with engineering."
"This controls who can access your app. It has a security gap: failed access attempts aren't logged, so you'd have no visibility if someone tried to break in."
"JWT verification with try/catch — stateless auth pattern. Issue: catch block swallows errors silently, preventing audit logging. Consider: structured error logging (Winston/Pino) + error classification for rate-limiting downstream."
No credit card needed to start. Pro unlocks unlimited clarity.

Not at all. CodeBabel is built specifically for people who don't code — founders reviewing PRs, PMs decoding Jira tickets, students learning, or anyone staring at an error they don't understand. You just select the code and hit explain.
CodeBabel supports 21 languages: English, Hinglish (Hindi + English mix), Hindi, Marathi, Bengali, Telugu, Tamil, Gujarati, Kannada, Punjabi, Spanish, French, German, Portuguese, Russian, Arabic, Chinese, Japanese, Korean, Indonesian, and Turkish.
The selected code is sent to our Gemini AI proxy to generate the explanation. We don't store your code snippets after processing. We recommend not submitting code containing sensitive credentials or PII. See our Privacy Policy for full details.
Each time you ask CodeBabel to explain a new snippet of code, that's one snap. Follow-up questions on the same snippet don't use additional snaps. Free plan gets 25 snaps per month. Pro users get unlimited snaps. You can also buy top-up packs if you need extra without going Pro.
