A live preview plays right in your browser: the lines race, the counters climb, the winner takes the end-card.
Render a finished MP4 sized for TikTok, Reels, Shorts, X or YouTube. No editing, no signup — download and share.

One click loads the matchup — tweak anything before you render.
Adjusted closing prices from Yahoo Finance, including splits and dividend adjustments. Charts show real historical performance — nothing is simulated or projected.
Yes and no. Creating previews and rendering videos is free with no signup. An account (GitHub sign-in) is only for keeping your past renders in a dashboard.
Anywhere that accepts MP4 — TikTok, Instagram Reels, YouTube Shorts, X. Each format option matches the platform's native aspect ratio so nothing gets cropped.
No. Historical data is shown for illustration only, past performance does not indicate future results, and none of the comparisons should be read as a recommendation.
The watermark keeps the tool free and travels with your video when it's reposted — it's how more people find the tool. It sits inside the chart area so it survives cropping.
Renders are kept for 24 hours before they expire. Download the MP4 or sign in to keep them in your dashboard.
