Vectorless

A hierarchical, reasoning-native document intelligence engine. no vector db, no embeddings.

⭐ Star us on GitHub — it helps the project grow!

Features

• Tree-based indexing — Documents organized as hierarchical trees, not flat vectors
• LLM-driven retrieval — Uses reasoning to navigate document structure
• No vector database — Eliminates embedding infrastructure complexity
• Multi-format support — Markdown, PDF (basic), HTML/DOCX (planned)
• Workspace persistence — LRU-cached storage with lazy loading
• Pluggable retrievers — LLM navigate, beam search, MCTS, hybrid

Quick Start

• Add to Cargo.toml:

[dependencies]
vectorless = "0.1"

• Create vectorless.toml in your project root (auto-detected):

cp config.example.toml vectorless.toml

use vectorless::client::{Vectorless, VectorlessBuilder};

#[tokio::main]
async fn main() -> vectorless::core::Result<()> {
    // Create client (auto-loads config from ./vectorless.toml)
    let mut client = VectorlessBuilder::new()
        .with_workspace("./workspace")
        .build()?;

    // Index a document
    let doc_id = client.index("./document.md").await?;

    // Query
    let result = client.query(&doc_id, "What is this about?").await?;
    println!("{}", result.content);

    Ok(())
}
