Fast, focused, and built for high-volume annotation. No bloat — just the tools you need to label faster.
From solo researchers to enterprise annotation teams — here's what they're saying.
"We annotated 40 hours of dashcam footage in a week. The interpolation tool alone saved us from redrawing boxes on every single frame."
"Finally a platform where my annotators don't burn out. Keyboard shortcuts and frame-skip controls make the workflow actually bearable at scale."
"We moved from CVAT to FrameMark for the review pipeline. Having a QA pass before export cut our re-training cycles by half."
"Our team labels surgical video for medical AI. Data never leaving our servers wasn't optional — self-hosting made FrameMark the only viable choice."
"Polygon and keypoint tools on the same timeline as bounding boxes — no switching tools mid-session. It sounds small but it's massive for throughput."
"I manage 20 freelance annotators across three time zones. Task assignment and per-frame audit trails mean I always know exactly where a project stands."
Everything you need to know before getting started.
