MainframePunch

MainframePunch turns your words into animated, authentic-looking computer punch cards—complete with classic hole patterns and satisfying punch sounds. Add your own brand caption, preview the animation, then record a crisp video to share anywhere. No accounts, no cloud, just retro messaging made simple. What you can do: * Create true-to-spirit 80-column punch cards with classic row/zone labels. * Preview live with “Punch Cards,” or capture a video with “Record & Share.” * Add a bottom caption (your brand or message) to every card. * Toggle letters on/off above each column; reveal them as the holes are punched. * Enjoy synchronized punch audio timed to each column. * Flow long text across multiple cards automatically (up to 20 cards). * See estimated card count and video length before you punch. * Save a composite image of the stacked cards after a run. * Adjust animation speed and card scale for the perfect look. * Share using the iOS system share sheet (iMessage, Mail, social apps, etc.). * Private by design: all processing happens on your device. How it works: * Type or paste your message in the Punch Contents box. * Tap “Punch Cards” to preview—or “Record & Share” to export a video with sound. * Share the result right from the iOS share sheet. That’s it. Why it’s delightful: * Authentic look & sound: the timing, holes, and motion feel like the mainframe era. * Brandable: add a tasteful caption along the bottom of every card. * Flexible: hide letters for a pure punched-holes look, or show letters as they appear. * Fast: export a clean MP4 in seconds; no sign-in or servers required. Great for... * Geeky greetings, inside jokes, and team shout-outs. * CS classes and museum demos (Hollerith encoding made visual). * Creators who want a distinctive vintage look for Reels/Shorts. * Tech culture moments—release notes, conference promos, easter eggs.
