What each one is
txtai
txtai is an all-in-one embeddings database for semantic search, LLM orchestration and RAG, bundling vector indexing, pipelines and workflows in one package.
- Vector search, pipelines and workflows together
- Runs fully locally
- Minimal dependencies
Guidance
Guidance is a programming paradigm for steering LLMs that interleaves control flow with generation, with constrained decoding and rich templating.
- Fine control interleaved with generation
- Constrained decoding cuts token waste
- Works with local and hosted models
Key differences
txtai is embeddings / RAG framework, while Guidance is constrained generation library. Their licenses differ (Apache-2.0 vs MIT), which matters if you ship a commercial product. txtai leans more intermediate-friendly, whereas Guidance is more suited to advanced users. They also differ in how they run (Self-hosted vs Cloud-optional). In short, txtai fits semantic search and RAG in one tool, and Guidance fits developers scripting complex generation logic.
Which should you choose?
Choose txtai for semantic search and RAG in one tool. Choose Guidance for developers scripting complex generation logic.
There is rarely one winner — many setups use both. The right pick depends on your hardware, your team's skills, and whether you value simplicity or control.
