Bumper — the motion graphics tool I wanted to exist. My
AI video tools charge you per second because they run on GPUs. But a lower third isn't a generation problem, it's a rendering problem — 105 deterministic frames a browser can draw for free. Same input, same 105 frames, every time. So I built the thing that treats it that way: pick a preset, tune it on a real timeline with named layers and visible easing, drop your own footage underneath, then export a transparent overlay for your edit or the finished shot with the footage baked in. No credits. No subscription. No GPU bill to pass on to you.
Built in Flowstep and driven through the Flowstep MCP server from Claude Code — every screen prompted straight onto the canvas instead of pushed around by hand. 8 screens on one design system: New graphic → Add footage → Editor → Brand kit → Export, plus the landing page, sign up, and an alpha variant of the editor.
Attached: the full walkthrough, plus a recording of the Flowstep canvas behind it.
Finished this after the buzzer, so it's out of the running. Posting it anyway — I'd rather it exist here than nowhere.
