Comparison

BrainTube vs Supermemory

Both give your AI persistent memory over MCP. Supermemory is a memory API developers build with. BrainTube is the finished product — save a video, article or podcast, and any AI can query it, no code.

Quick verdict

Pick Supermemory if you're a developer embedding memory into your own AI product. Pick BrainTube if you want your own watched, listened and read knowledge queryable by every AI you use, with zero code.

Where Supermemory fits

Supermemory positions itself as a memory layer and context-engineering platform for AI agents — a developer API/SDK with a newer personal app and an MCP server on top. If you're building an AI product and need long-term memory primitives you control, that's the lane.

Where BrainTube fits

  • Multimedia auto-capture — YouTube transcripts, podcasts, articles, PDFs, EPUBs, screenshots. Things you'd never sit down and type into a memory API.
  • Cited recall — answers point back to the exact segment in the original source.
  • MCP-native across Claude.ai (one-click OAuth), Claude Desktop, Cursor, and any MCP client.
  • No-code from day one — install, save, query. No SDK to wire up.

Same MCP bet, different shape

Both teams agree memory shouldn't live inside one chat app. The disagreement is who fills it. Supermemory hands developers the primitives. BrainTube compiles your own knowledge base from what you already consume — and exposes it to every AI you'll use.

Frequently asked

Are BrainTube and Supermemory solving the same problem?
They share a wedge — give AI persistent memory over MCP — but sit at opposite ends. Supermemory is primarily a memory API developers build with. BrainTube is a finished product: save a video, article or podcast and any AI can query it over MCP, no code.
Who should pick Supermemory?
Developers and teams embedding long-term memory into their own AI product, with a memory SDK, API, and infrastructure they control.
Who should pick BrainTube?
Individuals and operators who want their own watched, listened and read knowledge queryable by every AI they use — Claude, ChatGPT, Cursor — without writing code.
Do both speak MCP?
Yes. Both expose an MCP server, so MCP-compatible AI clients can read from either. The difference is who fills the memory: your code (Supermemory) or your saves (BrainTube).
