# Versuno

> Building the universal memory and context layer for AI agents.

Versuno gives AI agents persistent, structured memory and context they can rely on.

Today we have 2 live products:

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

Our next goal is to give any agent a persistent, structured, evolving memory brain it can read from and write to across sessions and tools.

## Access

- REST API
- MCP server: Claude Code, Cursor, VS Code, Windsurf, OpenCode, Codex, Cline, and any MCP-compatible agent
- CLI: sync prompts to your terminal and CI

## FAQ

### General

### What is Versuno?

Versuno is an all-in-one AI Assets management platform where you create, manage, test, evaluate, and collaborate on your prompts, personas, contexts, and system prompts.

### Who is Versuno for?

Versuno is for anyone working with AI on a regular basis - prompt engineers, marketers, content creators, product teams, and AI enthusiasts. It's built with simplicity in mind, so you don't have to invest 5 hours learning it before using it. Whether you're using AI for productivity, managing prompts for your team, or want to create your own AI Assets library for various use cases, Versuno helps you save time, work faster, and more reliably.

### Is there a free plan available?

Yes! Versuno offers a free plan that's perfect for getting started and exploring the platform. The free plan includes:

• 10 projects

• Unlimited public assets

• Up to 10 private assets

• Access to all core features

For full details on what's included and to see paid plan options, visit our [pricing page](/pricing).

### How is Versuno different from other prompt management tools?

Most prompt libraries just store your prompts. Versuno goes beyond storage with:

• **Automatic version control** so you never lose a working version

• **Real-time testing** across 50+ AI models side-by-side to compare outputs instantly

• **Expert-based evaluation** with detailed quality scoring and improvement insights

• **Four asset types** (prompts, personas, contexts, system prompts) organized in one place

• **AI-assisted building** with Sage to create high-quality assets faster

### What AI assets can I manage with Versuno?

Versuno supports four types of AI assets:

• **Prompts** – Instructions for specific tasks

• **Personas** – AI personalities and roles for consistent behavior

• **Contexts** – Background knowledge and guidelines

• **System Prompts** – Foundation-level instructions that define AI behavior

You can organize all of them in projects, tag them, version them, test them, and evaluate them - all in one platform.

### Does Versuno support version control for prompts?

Yes! Every time you save changes to any asset (prompts, personas, contexts, or system prompts), a new version is created. You can:

• See exactly what changed with inline diff views

• Add optional notes to describe each change

• View full version history with timestamps

• Restore any previous version with one click (requires confirmation)

Version control is automatic and included from day one.

### How does the AI testing playground work?

The Testing Playground lets you test your prompts across 50+ AI models in real-time:

1. Type or select the prompt from the library in the playground

2. Select models you want to test (GPT, Claude, Gemini, Grok, and 50+ others via OpenRouter)

3. Run the test and see all outputs appear side-by-side in real-time

4. Compare results to find which model performs best for your use case

5. Results auto-save to your library for future reference

You can test text-based models now, with image model support coming soon.

### Pricing

### How does usage-based pricing work?

Versuno meters three independent kinds of usage, each with its own monthly allowance:

- **Basic Brain Queries**: fast vector search and retrieval

- **Chat Messages**: in-app brain chat

Each meter is counted separately and resets every month. You pay only for what you use: upgrade for higher base limits, or buy a usage top-up when you need more.

### Do all plans include API and MCP access?

Yes. **Every plan, including Free, includes full API and MCP access.** You never need a higher tier just to connect Versuno to your agents — the plans differ only in how much monthly usage they include.

### What happens if I exceed my monthly limit?

You have two options:

- **Buy a usage top-up**: one-time credit packs (Starter, Growth, Developer) that add capacity across all three meters. **Credits never expire.**

- **Upgrade your plan**: Pro and Team include higher base allowances every month.

Limits are tracked per meter, so if you run out of just one (say re-ranking), a top-up refills all three.

### How does Team pricing work?

The Team plan is **pooled across your whole team**. The base plan covers **5 seats**, and you can add more as you grow.

Every seat contributes to a shared monthly pool - at the 5-seat baseline that's 60,000 basic queries, 20,000 re-ranking operations, and 2,500 chat interactions per month, shared by everyone.

Work in a **personal workspace** draws from your personal allowance; work in the **team workspace** draws from the shared team pool. The two are never mixed.

### Does unused usage roll over?

Subscription usage resets monthly. Top-up usage you purchase never expires. It's in your balance until you use it.
