Provenance

A funscript outlives the machine that made it. It gets published, shared, forwarded and re-uploaded for years. So every script FunGen generates says that it was generated, in the file itself, in a form anyone can read without asking FunGen and without using the software.

What FunGen writes into a generated script

• creator_software, set to FunGen, and creator_software_version, set to the app version that wrote the file.
• An ai-generated tag, marking a script whose content came from AI generation rather than from hand authoring.
• A fungen-tracker: tag naming the tier and the content kind that produced it, for example fungen-tracker:Pro VR 2.4.3 or fungen-tracker:Free 2D 2.4.3.

The labels stick

The first generator wins. Once a script carries these marks, re-saving it, editing the points, or running a second pass over it does not remove them and does not relabel it as something else. Opening someone else's script in FunGen and saving it never stamps their work as FunGen's.

If you set your own author name or a licence on a script, FunGen keeps them. It only fills those fields when they are empty, so a script you authored stays credited to you.

On export you can add an _ai suffix to the filename, so the disclosure survives even for someone who never opens the file.

Checking a script you did not make

A .funscript is a text file. Open one in any text editor and look for creator_software and the tags array. Everything above is plain, readable and stable across versions, which means a site or a community that asks for AI-generated scripts to be declared can check it mechanically rather than relying on the uploader to be honest.

What is never in the file

The marks say what made the script. They say nothing about who made it or where. A generated script never carries:

• Any identifier for you, your machine, your licence or your pass.
• The path, folder or file name of the video it was generated from.
• Model names, internal tracker names, or any detail of how the generation was tuned.

Tier and content kind are disclosed because a reader has a fair claim to know what produced a script they are about to load. The rest is either nobody else's business or FunGen's.
