VAAS-X vs a vector database: what each is for

The short version

Use a vector database when you need general similarity search over documents or other data. Use VAAS-X when what you want is memory: a record of what happened, what was done and how it turned out, with recall that favours what worked.

Side by side

	VAAS-X	a vector database
What it stores	Episodes: what was observed, what action was taken and how it turned out.	Vectors and the data attached to them.
What it returns	The closest matching episodes, ranked toward the ones with the best outcomes.	The nearest vectors to your query.
What you build yourself	Nothing for the memory itself: outcome tracking, recall ranking and a memory per device are included.	Outcome tracking, ranking, per-user or per-device separation and the agent connector.
How you pay	A flat monthly plan, with no per-query bill. Free £0. Personal £9.99 a month. Developer £19. Professional £99. Enterprise from £2,000. Flat monthly price.	Varies by product. Many price on storage and query volume.
Agents	One connector address (MCP) for Claude, Cursor, VS Code and others.	You write the glue between your agent and the database.
Devices and machines	Runs on a standard CPU with no GPU, down to small devices. Bootstrap connects sensors with no schema design.	Depends on the product.
Checking the claims	A reproduction guide for each published result, including search speed on a million vectors.	Depends on the product.

The vector database column describes the category in general, not one product. VAAS-X details are from our pricing page. Details can change: if anything here is out of date, tell us at support@vaasx.com and we will fix it.

Where a vector database is the better choice

General similarity search over documents, product catalogues or any data you want to index yourself.
Full control over the index, the embedding model and the ranking.
You may already run one, and adding memory to it is a smaller step than adding a service.

Where VAAS-X is the better choice

You want memory for agents or devices, not a search index to build memory on.
You want recall that favours what worked, without writing the ranking.
You want a price that does not grow with queries.

Check it for yourself

Every VAAS-X result has a reproduction guide you can run on your own machine. The Free plan needs only an email address and no card, and the pricing page shows every plan and limit.
