Our summary

Jeved is an add-on for a chat program called SillyTavern. It helps you guide an AI assistant automatically during a story. You can use it to keep track of character items, fix the narrator's tone, or ask for new events when the conversation gets boring.

The software sends parts of your chat to Jev, an AI tool that chooses from options rather than writing an answer. You write rules based on these choices. If a rule matches the chat, it can change a list, replace a bad reply, add text instructions, or run executable tools.

This tool helps readers control their chat stories without typing out every direction. It requires a private access code for a chosen provider. Because automatic changes can disrupt a session, you should test your rules in a safe chat first to ensure they work correctly.

Key takeaways

Install the add-on, enter your private access code, and run the built-in test before making rules.
Build rules by combining questions and actions, which only trigger when the conversation matches your conditions.
The software only checks the chat when an active rule needs that specific information.
