You build an agent. It works great at first. Then — personality drift and hallucinations. We solved this: the first API that keeps your AI agent's character stable indefinitely. Connect in 5 minutes.
3 agents free forever · No card required · No vendor lock-in
The first 50 messages — the agent is sharp, in role, responds correctly. Then the conversation stretches, context grows, and the agent starts: apologising where it shouldn't, shifting tone, forgetting constraints, breaking character. This is personality drift — and it's not a bug in your implementation. It's a fundamental problem with modern LLMs.
Users leave after the agent "breaks" — and don't come back. One broken conversation costs more than it seems.
The team spends days rewriting the system prompt after every drift. Patch on patch, regressions never stop.
"Your bot said X, then Y, then Z — which is true?" Support wastes time explaining AI behaviour.
One screenshot of a broken agent — a thousand lost users. Viral failures are remembered for a long time.
Anthropic, OpenAI, Google haven't solved this at the API level. Memory helps the agent remember facts. Personality keeps the agent who it is. We solved the second one.
A layer between your application and any LLM. It doesn't store facts. It holds character.
5 precise rules hold an agent's role more reliably than 500 lines of system prompt. Fewer tokens — higher stability — cheaper inference.
Configured personality on Claude? It transfers to GPT-4, Gemini, Llama preserving 94% of characteristics. Switching models doesn't mean switching personality.
No vendor lock-in. Migration without losing agent character. One configuration — any provider.
Describe the personality in free form or via parameters. The API builds a stable profile.
One endpoint instead of direct LLM calls. Your code doesn't change — just the URL.
The dashboard shows Personality Stability Score in real time. Alert if anything changes.
// Create an agent { "name": "support-agent", "personality": "Precise, friendly, never promises what can't be delivered", "model": "claude-3-opus" } // Response { "agent_id": "ag_xxx", "status": "stable", "stability_score": 1.00 }

An AI dispatcher handles calls, qualifies leads, books appointments. Runs 24/7. Thousands of messages per week.
Before Personality Persistence: the agent broke character after ~80 messages, confused intake protocols, gave contradictory pricing information.
After: stable across sessions of any length. Protocol followed precisely. Staff stopped reviewing every second conversation.
"The agent finally behaves the way we configured it — always, not just at the start of the conversation."— Alexey, auto service owner
Personality drift is expensive. Fixing it — isn't.
