ErasezoNothing is uploaded
Images and video are decoded, cleaned and saved locally. Your account only ever exchanges sign-in and credit counts.
Remove the watermark.
Keep the pixels.
from images & video
Erasezo strips the stamp from what you generate in Gemini, AI Studio and Google Flow — no manual steps, no second tool, no upload. The work happens on your machine and you get the file back clean.

On your device
Your files never leave the browser.
The removal runs in the page, on your own hardware. There is no upload step, no queue, and no copy of your work on a server — because there is no server in the path at all.
No queue to wait in
Nothing is batched on someone else's GPU. The work starts the moment you click and finishes at the speed of your machine.
Works while you generate
Turn on auto-removal and the watermark is gone as the file downloads, without a second round trip through another tool.
How it works
Three steps, then it stays out of the way.
Install and sign in
Add the extension, open the side panel, and sign in. You get 15 credits a day without paying anything.
Generate as you normally would
Erasezo puts a button on each generated tile in Flow, and cleans downloads from Gemini and AI Studio in place.
Take the clean file
Or drop any image or MP4 straight into the panel — PNG, JPG and WebP for stills, 720p and 1080p for video.
Where it runs
Four surfaces, one panel.
Each of these is a place Google puts a watermark on something you made. Erasezo attaches to all of them from the same install.
| Surface | Images | Video | How it appears |
|---|---|---|---|
| Gemini | Yes | Yes | Cleans the file as you download it |
| Google AI Studio | Yes | Yes | Cleans the file as you download it |
| Google Flow | Yes | Yes | A button on each generated tile |
| Google Docs video | — | Yes | Cleans on insert |
| Anything else | Yes | Yes | Drop the file into the side panel |
Controls
When the automatic pass isn't enough, you get the dials.
Most files need nothing. For the ones that do, the detector is not a black box — every threshold it uses is in the panel, with the defaults it shipped with.
Mask size
Grows the treated area when a stamp sits slightly outside where it was found. Left at 1.00× it treats exactly the detected region.
Gain when the stamp drifts
How hard to push when the mark is not where it usually sits. Lower it if a correction is leaving a soft patch behind.
Accept and trust thresholds
The match scores that decide whether a watermark is really there. Lower the accept threshold to catch fainter marks.
Scan stride
How finely to search when the stamp has moved. Smaller is more thorough and slower; 8 pixels is the balance it ships with.
Pricing
Free every day. Pay only if you outgrow it.
One credit is one cleaned file. Credits refresh daily — they don't expire and they don't roll over.

Questions
The things worth knowing first.
Do my images get uploaded anywhere?
No. Decoding, detection and reconstruction all happen in your browser. The only things that travel to us are your sign-in and your credit balance.
What counts as a credit?
One cleaned file. A free account gets 15 a day, refreshed at midnight UTC. Nothing is deducted when a file turns out to have no watermark on it.
Which video resolutions work?
720p and 1080p MP4. Upscaled 4K exports are not supported yet — the mark lands differently after Flow's upsampler, and a bad correction is worse than none, so the panel tells you instead of guessing.
Google Flow now has its own watermark toggle. Do I still need this?
If your Flow account has the built-in option, use it — the extension will offer to stand down for Flow and keep working on Gemini and AI Studio. Running both is just extra processing.
Can I use it on files I didn't make in Google's tools?
Yes. Drop any PNG, JPG, WebP or MP4 into the side panel. The detector is tuned for Google's sparkle, so results on other marks vary.
What happens to my credits if I cancel?
You return to the free tier and keep getting 15 a day. Nothing you have already cleaned is affected.
