# Versuno

> The universal memory and context layer for AI agents.

Versuno gives AI agents persistent, structured memory and context they can rely
on across sessions and tools. Two products are live today; a shared memory brain
agents write to over time is what we're building next.

## The problem

AI starts every session from zero — forgetting your decisions, docs, and
conventions the moment the context window closes. The hard part of AI isn't the
model, it's memory.

## Products

- **Public Brains** — clean, queryable knowledge graphs for popular libraries and
  frameworks, ready for any AI agent to query for grounded context.
- **Prompt Manager** — a versioned library for the prompts your AI runs on:
  prompts, personas, contexts, system prompts, and skills.

## For agents

Agents can sign themselves up for an API key with one unauthenticated request —
no human, no email inbox required.
