Loosely inspired by LangChainJs This library seeks to enable core LangChain functionality but using Elixir and OTP idioms. It provides low-level structures you can use to build your own language chain applications as well as high-level GenServers for accomplishing common natural-language processing tasks very quickly.

Scraper holds language chains that extract structured data from natural language text. It has a handy "default_scraper" that can be used out of the box.
In your Application tree:
{LangChain.Scraper, name: :scraper},In your code:
description = "Hi I'm Nermal an 11th-level magic user with 30 hit points, I have a wand of healing and a cloak of protection in my inventory."
character_schema = "{
name: String,
class: String,
hitPoints: Int,
inventory: [String]
}"
{:ok, result } = LangChain.Scraper.scrape(:scraper, description, "default_scraper", %{ outputFormat: "YAML", inputSchema: character_schema })
IO.puts result.text
" name: Nermal
class: magic user
hitPoints: 30
inventory:
- wand of healing
- cloak of protection
"
