There’s a simpler way to ground your AI.

Antfly’s retrieval engine helps apps and agents navigate your knowledge sources.

Loved by developers at

The retrieval pipeline with zero pipes.

Chunking, embedding, indexing, reranking: it all happens inside the engine as data arrives. There’s nothing to wire together and nothing to keep tuned.

On top

Antfly sits on your Postgres, your buckets, your file systems, your docs. Nothing to migrate, nothing to replace.

Any shape

PDFs, screenshots, tables, audio: every context layer becomes food for the retrieval engine.

Unified API

Vector, keyword, and graph search are indexes inside one database, fused in a single query plan. The inference that chunks, embeds, and reranks runs in there too. That’s where the pipes went.

Private

None of that inference leaves your infrastructure. No third-party API ever sees your data.

Built-in models

Retrieval needs a model at every step: embeddings when documents arrive, a reranker when queries run, an extractor to build the graph. Antfly ships them inside the engine, so there’s nothing to deploy and nothing to call out to.
