BrrainyA Memory You Use vs. A Memory API You Call
Brrainy vs. Supermemory
Supermemory sells memory infrastructure to developers: namespaces, SDKs, a managed MCP server and coding-agent plugins, on usage-metered plans from $19. If you are shipping a product that needs memory, that is the right shape, and their own docs are blunt that the engine is not your system of record. Brrainy sits on the other side of that line: a memory you use yourself, across the assistants and apps you already work in, served to your agents over MCP. Pricing and product pages checked on 23 October 2026; Brrainy publishes this page.
Side-by-Side Architectural Matrix
Objective comparison based on verifiable technical capabilities and public rate cards.
| Capability | Supermemory | Brrainy |
|---|---|---|
| Who it is for | Developers embedding memory in an application they are building. | People and teams who want their own work remembered, including non-developers, without integrating an SDK. |
| What feeds it | API writes, plus connectors for Drive, Gmail, Notion, OneDrive, GitHub, Granola, S3 and a crawler; Gmail is gated to the $100 Max plan. | Assistant capture, 25 app connectors, and the web, desktop, mobile, browser and IDE surfaces. |
| Retrieval surface | Managed MCP server with nine tools, plus coding-agent plugins. | Hosted MCP server with two tools, brain_recall and brain_remember, for any MCP-capable client. |
| Delivery | Reactive: your application asks, the engine answers. | Proactive as well: a scheduled brief arrives by email, in-app inbox or push without a query. |
| Isolation | Namespaces as a hard boundary; their own docs note that a namespace alone is not authorization. | Spaces with row-level isolation between personal and organisation work. |
| Pricing shape | Usage-metered API plans: $19 Pro, $100 Max, $399 Scale, enterprise custom, metered beyond included usage. | Subscription plans with BYOK on model compute; current plans are on the pricing page. |
When Supermemory is the right choice
You are shipping a product and want a memory engine behind your own API, with a namespace per customer and usage you can meter and resell.
When Brrainy is the right choice
You want the memory for your own work - across the assistants and tools you already use - with a brief that arrives and agents that can read it.
