Describe the mod. Get the files.
VibeModder puts an AI coder to work on your game's mod files. Say what you want changed, upload what you have, and get the files back with a note on what was checked and what still needs a test in game.
Log in with your Astropond account. Same login, same balance.

- Your files backAs downloads, kept in your file manager until you delete them or they expire.
- What is still untestedThe coder cannot play the game, so it tells you what to try in game.

Halve the FP cost of my Moonveil's skill. My regulation.bin is attached.

How it works
-
Pick a game and a coder
Choose one of six AI models, each rated by Luka for modding. Switch coders whenever you like; the new one gets the conversation so far.
-
Describe it, attach your files
Say what you want in plain words. Attach the mod files you have, a crash log, or a short video of the problem.
-
Get your files back
The coder edits, checks and sends the files as downloads, with what it verified and what you should try in game. Rewind the session if a turn went the wrong way.
Pick your game
Elden Ring is open to every account. Minecraft is in beta with testers. More games will follow.
Six coders, graded by Luka
LR is Luka's Rating: how he rates each model overall for modding, cost included. Power is his rating of the model's own intelligence when it makes mods, price left out. Luka built the coder; the notes are his words.

Questions
Anything else? Ask in the workbench's support chat once you are logged in.
Do I need a new account?
No. Log in with your Astropond account. If you do not have one yet, signing up here creates an Astropond account that also works on astropond.com.
What do I pay for?
Only the AI model's usage, at Astropond's prices, from your Astropond balance. The modding tools, the knowledge base and the box they run on cost nothing. The workbench shows each coder's live price before you send a message.
Are mods sold here?
No. VibeModder never sells mods or puts them behind a payment. You pay for the AI model the coder runs on, the same way you would on Astropond.
Does the coder test my mod in the game?
No, it cannot play the game. It runs the checks it can (a param verify and a diff against your upload for Elden Ring, a sandboxed build and GameTests for Minecraft) and tells you exactly what is still untested. You try it in game and tell it what happened.
What files can I upload?
For Elden Ring: regulation.bin, HKS scripts, binders, other mod files, zips and video clips. For Minecraft: mod jars, modpacks and crash logs. Each file can be up to 2 GB, and your account keeps up to 10 GB of files.
How long are my files kept?
The file manager in the workbench shows the deletion date of every file, and you can delete any of them earlier yourself.
Can I undo a turn?
Yes. Rewind the session to an earlier message and carry on from there.
Which games can I mod?
Elden Ring, on every account. Minecraft is in beta with testers. The workbench shows the games your account can use.
Is VibeModder official?
No. VibeModder is not affiliated with FromSoftware, Bandai Namco, Mojang or Microsoft.
