Nina Calloway

Nina Calloway builds the image and video tools at AT USE — the converters, compressors, background removers, crop tools, GIF makers, and the cluster of YouTube helpers and subtitle tools.

She came to tool-building through design work: too many HEIC files to convert after a shoot, too many rounds of "compress this before sending," too many video frames to extract manually. The tools that existed were either good but paywalled, or free but slow and ad-heavy.

Her tools at AT USE reflect what she actually wanted: server-side processing (so files never sit in a browser tab), output formats that cover real-world creative workflows, and an interface that doesn't treat "free" as a business model trap.

Based in Tel Aviv. Working independently.
