Crate vectorless 

Vectorless

A reasoning-native document engine for AI.

It will reason through any of your structured documents — PDFs, Markdown, reports, contracts — and retrieve only what’s relevant. Nothing more, nothing less.

Quick Start

use vectorless::{EngineBuilder, IndexContext, QueryContext};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let engine = EngineBuilder::new()
        .with_key("sk-...")
        .with_model("gpt-4o")
        .with_endpoint("https://api.openai.com/v1")
        .build()
        .await?;

    let result = engine.index(IndexContext::from_path("./document.md")).await?;
    let doc_id = result.doc_id().unwrap();

    let result = engine.query(
        QueryContext::new("What is this about?")
            .with_doc_ids(vec![doc_id.to_string()]),
    ).await?;
    println!("{}", result.content);

    Ok(())
}
