Context engine vs. RAG
RAG retrieves relevant text. A context engine builds the right working set. RAG is a retrieval step. A context engine is a complete pipeline replacement.
What RAG does
RAG embeds text as vectors and retrieves chunks by cosine similarity to a query. It answers one question well: what text in the index is most similar to this input?
- Document Q&A
- Knowledge base search
- Single-turn queries
- Staleness — no mechanism to mark information as superseded
- Conflicts — contradictory chunks surface side by side
- Write-back — outcomes are not fed back into the context store
- Compound improvements — each session starts from zero
What a context engine does
A context engine replaces the entire retrieval and assembly layer — not just the similarity search step.
Ingest → structure → rank → assemble → write back. Every stage feeds the next so the working set is always current and coherent.
- Staleness and supersession
- Conflict resolution across sources
- Multi-source coherence
- Outcome write-back to improve future sessions

The migration path
Cilow replaces the retrieval and prompt assembly layer. Your model and app logic stay the same.
Point Cilow at your existing sources. Cilow ingests and structures the data — no manual reindexing required.
Swap the retrieval + reranking + assembly logic for a single API call. The response is a coherent working set, not a ranked list of chunks.
Cilow tracks staleness, resolves conflicts, and writes outcomes back automatically. Each session improves the next.
Frequently asked questions
Can RAG and a context engine coexist?▾
No migration is needed. Cilow replaces the retrieval + assembly layer entirely. You keep your model, your agent framework, and your application logic unchanged.
Does switching from RAG require reindexing?▾
Cilow ingests from your existing sources. You connect your data and Cilow builds the context layer — no manual reindexing required.
Is a context engine harder to set up than RAG?▾
Cilow provides a single API that replaces the retrieval, reranking, and assembly steps you would otherwise build and maintain separately.
Stop patching retrieval with more retrieval. Replace the whole layer in one step.
