Stop Googling the Same Thing Twice.

Save code snippets as you learn. CodePulse schedules your reviews using the SM-2 algorithm so you actually remember them.

How it works

Save once. Review smart. Never forget.

Save your snippet

Paste code and write what you learned. Tags and language are auto-detected.

SM-2 schedules your review

The algorithm calculates exactly when you'll start to forget — and reminds you.

Rate and retain

Quick flashcard review. Forgot it? Review again sooner. Nailed it? See you in 3 weeks.

The science — Ebbinghaus Forgetting Curve

Features

Everything your memory needs. Nothing it doesn't.

SM-2 Algorithm

Never forget with spaced repetition

The SM-2 algorithm — same science behind Anki — schedules each snippet at the exact moment your memory starts to fade.

useCallback optimizationTypeScript

const memoized = useCallback((deps) => {
// avoid re-renders
})

Find anything instantly

TF-IDF semantic search ranks results by relevance — not just keyword match. Built from scratch.

>useCallback optimization

useCallback with deps94%

useMemo vs useCallback87%

React.memo performance71%

No duplicate clutter

Levenshtein edit distance catches near-identical snippets before you save.

"useEffect cleanup pattern"

Your snippets auto-organize

K-means clustering groups related snippets into topics — no manual tagging required.

Turn clusters into content

Generate a dev tip thread from any topic cluster with one click.

🧵useCallback vs useMemo — a thread

2/useCallback memoizes functions, not values.

3/useMemo is for expensive computations.

Under the hood

Built from scratch. No black boxes.

All 5 algorithms implemented in pure Python — no scikit-learn, no NLTK, no pre-trained models. Because we wanted to understand every calculation that touches your memory.

“I used to re-Google the same Tailwind flex trick every week. After 3 weeks of CodePulse reviews, it's just in my head.”

Rahul K.

@rahulk_js · Junior Developer, Delhi

“The SM-2 algorithm is shockingly good. I reviewed a tricky useEffect cleanup once, and I still remember it 6 weeks later without touching it.”

Aisha M.

“The cluster view is my favorite part. I didn't realize how many React performance patterns I'd saved until they appeared as a group.”

“The duplicate detection saved me from saving the same useRef pattern three times. Small feature, huge quality-of-life improvement.”

Sujal B.

“My retention rate went from 40% to 78% in six weeks of daily reviews. The data in the dashboard is weirdly motivating.”
