Mutters VS godot-ink

There are two types of chatbots -- unreliable freeform ones (e.g. GPT-3) and reliable script-based ones (e.g. Alexa). I believe that what you're looking to do (dynamic rewriting) is moreso an active research topic!

The script-based chatbots are very similar to those in the 80s, with one major addition -- the options at each choice point are now "intents" instead of exact text (e.g. "the user intends to order a taxi"). Machine learning is then used to classify whatever the user says/writes as an "intent," then the script is followed to the next choice point.

See this open-source project for an example of using Ink to drive a script-based chatbot similar to Alexa: https://github.com/rabidgremlin/Mutters

There's an Ink integration for Godot that works fairly well: https://github.com/paulloz/godot-ink

Haven't used it but this ink plugin exists if you're looking to stay within what you know.

It can be found on a dedicated branch on GitHub. Feel free to try it, break it and reach out to me.

Did you use ink (via godot-ink or similar) to author the visual novel? Or some other interactive fiction tool? Or something entirely custom?

Godot Ink

There's also a plugin for ink https://github.com/paulloz/godot-ink.

You could have a look at ink integration in Godot. Here is a repository for example: https://github.com/paulloz/godot-ink

I would say something like Inkle's Ink could do this easily, though it can be overwhelming to look at from the start. There are a couple of Godot integrations with Ink, both a C# one here and a pure GDScript one (though they warn it might be slow on large games). InkGD has a couple examples that use simpler Ink stories, so you might just look through that for the examples to start.
