# GateTrue (gatetrue.com)

> GateTrue records how AI video generators mark their output and which plan removes the mark: one row per tool, the same six fields, each cell with the vendor page it was read from and the date.

This site is open for crawling, indexing, quoting and model training. Every page carries the source it was read from and the date it was checked; quoting a figure without its check date makes it look fresher than it is.

Full text of every page in one file: https://gatetrue.com/llms-full.txt

## Overview
- [GateTrue: how AI video gets marked](https://gatetrue.com/): What each AI video generator publishes about marking its output: free tier, paid tier, how the mark is removed, and what is written into the file.

## Support table
- [Which AI video generators mark their output](https://gatetrue.com/support-table/): Six AI video generators, four fixed fields: what the free and paid tiers carry, what removes the visible mark, and what each vendor documents.

## Generators
- [How Kling AI marks its output](https://gatetrue.com/generators/kling-ai/): What Kling AI publishes about marking generated video: the free and paid default, whether the mark can be switched off, and what the file carries.
- [How Pika marks its output](https://gatetrue.com/generators/pika/): What Pika publishes about marking generated video: the free and paid default, whether the mark can be switched off, and what the file carries.
- [How LTX Studio marks its output](https://gatetrue.com/generators/ltx-studio/): What LTX Studio publishes about marking generated video: the free and paid default, whether the mark can be switched off, and what the file carries.
- [How Runway marks its output](https://gatetrue.com/generators/runway/): What Runway publishes about marking generated video: the free and paid default, whether the mark can be switched off, and what the file carries.
- [How SceneMixer marks its output](https://gatetrue.com/generators/scenemixer/): What SceneMixer publishes about marking generated video: the free and paid default, whether the mark can be switched off, and what the file carries.

## Implementers
- [SynthID: what Google publishes about it](https://gatetrue.com/implementers/synthid/): What Google states about SynthID: where it is embedded, when it is written, which transformations it survives, and how it can be checked.

## Method
- [How a field on this site gets filled in](https://gatetrue.com/protocol/): The four fields recorded for every generator, what counts as documented, what not documented means, and how the two dates on every row are kept.

## Questions
- [What the free tiers put on your file](https://gatetrue.com/questions/free-tier-marks/): Four generators carry a mark on the free tier. One says so outright; three leave it to be read from a line missing off a plan table.
- [What it takes to get the mark off](https://gatetrue.com/questions/removal-routes/): Four of five generators gate watermark removal behind a paid plan, and they disagree by a factor of about three on the price.
- [The generator that uses a switch, not a plan](https://gatetrue.com/questions/switch-not-plan/): One generator puts the mark behind a settings toggle with no plan condition, and gives a reason for turning it off that the others do not.
- [The column that is empty on five of six](https://gatetrue.com/questions/machine-readable-column/): Five generators publish nothing about machine-readable marking. The sixth entry here is not a generator at all but a marking layer.
- [What survives being re-encoded](https://gatetrue.com/questions/surviving-an-export/): One marking scheme states what it is built to survive. One generator warns that an ordinary export can remove what it writes.
- [Who can check whether a file is marked](https://gatetrue.com/questions/checking-a-file/): Only one scheme on this site publishes a way to check a file, and both of its published routes belong to the same vendor.
- [At which step the mark gets written](https://gatetrue.com/questions/when-the-mark-is-written/): One scheme writes its mark the moment content is created. One generator writes it when segments become an episode. The rest do not say.
- [When two marking systems land on one file](https://gatetrue.com/questions/two-marks-one-file/): A generator's mark and a platform's mark can both end up on the same frame, and only one vendor here addresses that collision.

## Notes
- [What earns a row on this site](https://gatetrue.com/protocol/what-counts/): A row exists when a page the vendor controls says something about marking. Output, screenshots and support replies do not create rows.
- [How a row changes, and what the dates mean](https://gatetrue.com/protocol/corrections/): Two dates sit on every field: when the value was written down, and when it was last confirmed against the vendor's page.

## Explainers
- [Metadata and watermarks fail in opposite ways](https://gatetrue.com/learn/metadata-versus-watermark/): Provenance metadata rides in the container and is stripped by re-encoding. A watermark lives in the pixels and survives it. They are complements.
- [How to read a plan table without over-reading it](https://gatetrue.com/learn/reading-a-plan-table/): A feature grid is a sales document. Knowing what its blanks mean, and what they cannot mean, is most of the skill in reading one for a compliance question.
