Frame Heart
Download
Clean plates,
every frame
Frame Heart finds a generator’s visible corner mark and removes it by itself, on pictures and on video. It works particularly well on images and videos made with Gemini.

Questions
Is it free?
Yes, completely: no ads, no subscriptions and no paid extras.
What can it remove?
Visible corner marks from AI generators: the Gemini sparkle, plus labels from Grok, Doubao, Jimeng, Tongyi, Qwen, Kling, Wenxin and Veo. It works on pictures and video, and particularly well on images and videos made with Gemini.
Does it hide that a picture is AI-made?
No. It removes the visible mark only. Invisible marks such as SynthID stay in the file. Please use Frame Heart on work you made or have the right to edit, and be open about AI work where that matters.
Will it touch a signature or a caption?
It looks for see-through labels placed tight in a corner. Solid text, and text further in, is left alone. Very occasionally a label can be missed, or a see-through signature in the corner can look like one, so check your files with Preview.
Does anything get uploaded?
No. Everything runs on your computer.
Does it need a graphics card?
Removing a mark doesn’t. Upscaling is much faster with one, and it can run on the processor if you choose CPU in Settings.
