# Unum Docs

> Five engineering positions behind Unum’s open-source stack, from 14 languages over one C ABI down to CPUs, GPUs and NVMe, with the mechanisms and code behind each

## Engines

- [USearch | One Index for Every Modality](https://www.unum.cloud/engines/usearch): USearch, Unum’s open-source search engine inside ClickHouse and DuckDB: one proximity graph for search, attention and sparse algebra over texts, genomes, maps and embeddings
- [UStore | One Store for Transactions and Analytics](https://www.unum.cloud/engines/ustore): UStore, Unum’s embedded database for blobs, documents, graphs, strings and pages: one transaction across every modality, scans and random sampling over the same copy, on local NVMe and GPUs
- [UForm | One Model for Every Modality](https://www.unum.cloud/engines/uform): UForm, Unum’s tokenizer-free multimodal encoders trained from scratch in CUDA: raw bytes of text, images, video and audio into one embedding
