Persista

Give your AI
a memory.

Persistent memory infrastructure for AI applications. Remember what matters, understand relationships, and retrieve the right context when your AI needs it.

Built for AI agents, copilots, assistants, and applications that learn over time.

AI shouldn't forget
between conversations.

Persista turns conversations into structured, searchable memory and brings the right context back when your agent needs it.

Step 01 / 05
Step 01

Conversation

Persista receives the conversation directly from your AI application.

Persista remembers what matters.

Persista remembers

Turn conversations into useful, persistent memories automatically.

Conversation

“Let's keep using Hono for CodePilot — and I always prefer TypeScript.”

Memory isn't just a vector.

AI needs more than semantic similarity. It needs to understand how things are connected.
