Individual developers and 1–5 person teams building agents
Indie devs & small teams
Three lines to a memory that doesn't gaslight you.
Correct a fact and watch the old one stay on record instead of vanishing.
The problem
You shipped an agent. It forgot something, or contradicted itself, and you spent an afternoon trying to figure out why — with no audit trail. Vector-first memory makes it worse: if the embedder hiccups, the write looks fine but the fact is silently gone.
Silent memory loss when the embedder fails — the write succeeds, the fact is unretrievable.
Documented in mem0 #5245How CLS++ handles it
Persistence comes from the engine's own tokenization, not the embedding — so a dead embedder degrades ranking but loses nothing. The SDK is three calls: learn, ask, correct. Swap it in over mem0 / LangGraph / CrewAI without a rewrite, get a free key, and run it against your own agent in minutes.
Under the hood — the real script
From clsplusplus import Brain — your first auditable memory in three lines.
pip install clsplusplusfrom clsplusplus import Brain
brain = Brain("my-agent")
brain.learn("Customer is on the Pro plan")
brain.correct("Customer is on the Pro plan", "Customer upgraded to Enterprise")
brain.ask("What plan is the customer on?")
# -> current belief; the old one is archived, not goneThe consumer benefit is indirect but real: the apps you ship give your users an AI that remembers correctly and can explain itself.
