# AI Helper
Folge has a built-in AI helper that can Expand, Rewrite, Shorten, Improve, and Simplify text for you. AI Helper operates with a BYOK (Bring Your Own Key) concept, which means you need to create an API key for AI services Folge supports and register it in the app. This means that Folge communicates directly with the AI providers, avoiding the need to send your data anywhere else besides AI services.
# Getting Started

# Available options

Folge supports the following AI providers:
- ChatGPT via
https://api.openai.com/v1/chat/completionsendpoint - Claude via
https://api.anthropic.com/v1/messagesendpoint - OpenRouter via
https://openrouter.ai/api/v1/chat/completionsendpoint - Custom OpenAI API Compatible — connect any OpenAI-compatible API by specifying a custom host and path
Each API provider accepts two values:
- Model name as free text
- API Key
# ChatGPT
- List of models (gpt-4.1 is recommended)
- Tutorial on how to create an API key
# Claude
# OpenRouter
# Custom OpenAI API Compatible
If you use a self-hosted or third-party OpenAI-compatible API (e.g. Ollama, LM Studio, Mistral, or any other provider), select Custom OpenAI API Compatible from the provider dropdown. You will need to provide:
- Api Host — the base URL of the API, e.g.
https://api.openai.com/v1 - Api Path — the endpoint path, e.g.
/chat/completions - Model — the model name as accepted by your provider
- API Key — your API key (if required by the provider)
# General Instructions
You can provide custom instructions that will be appended to every AI request. This is useful for setting a preferred tone, language style, or any other persistent guidance — for example, instructing the AI to always use formal language or to write in a specific language.
These instructions are sent with every action (Expand, Rewrite, Shorten, etc.) in addition to Folge's built-in prompt.
# Custom Prompt
You can replace Folge's built-in prompt entirely with your own. When a custom prompt is set, it is used instead of the default system prompt for AI Writing actions. This gives you full control over how the AI behaves — useful if you want a specific output format, persona, or domain-specific behaviour.
# Calling AI from the step description editor.
To use AI you need to either select text you would like AI to work with and click the dropdown to choose any action you would like AI to perform. By Just clicking the ✨ icon you will always trigger the Expand action
