Cache LangChain.js in your sales enablement tool with Crowkis

Building sales enablement tools on LangChain.js? Add a semantic cache so reps asking the same product questions stop costing full price.

Sales enablement tools built on LangChain.js share one problem: reps asking the same product questions. Each repeat is a full-price LangChain.js call for an answer you already have.

Put a semantic cache in front. Point LangChain.js's base URL at the Crowkis OpenAI-compatible gateway, or wrap the call in get-or-compute, and reworded repeats are served from cache, no rewrite of your sales enablement tools logic.

LangChain.js + Crowkis
base_url = "http://127.0.0.1:6380/v1"   # Crowkis gateway, semantic cache in front
In plain words: The sales enablement tools keep working exactly as before; the repeats just stop hitting the model.

On repetitive traffic this cuts costs up to 60-70% on repetitive workloads, and every hit carries a confidence score so reuse stays safe. Community edition ships at full power, free to run.
