REM Labs vs Supermemory
what's different, what's honest, when to pick which.

Supermemory ships a consumer second-brain app. REM Labs ships the continuity layer that apps like it are built on — nine consolidation strategies, 94.6% LongMemEval (vs 81.6%), full self-host, 80+ first-class integrations, and a consumer surface via console + iOS. Here's the side-by-side.

SUPERMEMORY: CONSUMER FIRST · NOVA APP · TWITTER / NOTION / CHATGPT · 81.6% LONGMEMEVAL
Every dimension Supermemory markets, here's REM's number.

Supermemory ships a clean consumer app. REM ships the continuity layer — with its own consumer surface (console + iOS) on top.

Consumer UI
REM Console (web) and the REM Labs iOS app give end users a typed, card-style second-brain UI — with the full Dream Engine, nine consolidation strategies, and 8 retrieval modes underneath. Apps built on REM inherit that depth.
Pre-built connectors
80+ first-class integrations maintained by REM — Notion, Slack, GitHub, Obsidian, Gmail, Twitter/X import, ChatGPT/Claude export import, Zapier, n8n. Typed, versioned, tested. Not community ports.
Distribution surface
REM ships a developer console, iOS app, CLI, MCP endpoint, A2A agent card, and webhooks. Every surface hits the same Apache-2.0 core. Builders reach their users through every channel, not just an app.
Developer infrastructure, not a consumer app.

Supermemory is a second-brain product; REM is the continuity layer your product builds on top of. Nine consolidation strategies, federated namespaces, webhook reactivity, protocol-native APIs — the substrate, not the end-user UI.

Different layer of the stack

Supermemory is an app; REM is an API. You could build something that looks like Supermemory on top of REM — we've talked to founders who are. But if you want a finished consumer second-brain today with zero code, Supermemory ships that and we don't.

Fourteen dimensions. Sourced, dated, honest.

Supermemory has a developer API (recently added), but their core product is the consumer app. We compare against the app + API as one integrated offering.

LONGMEMEVAL METHODOLOGY · /benchmarks

vs. Supermemory.

The two dimensions Supermemory markets hardest — and REM's actual numbers on each.

Consumer surface

REM ships a typed Console (web), an iOS app, a CLI, and a consumer-grade knowledge UI — with the full Dream Engine underneath. Non-technical users get the same second-brain experience; developers get the API.

  • Console + iOS app + CLI — unified across surfaces.
  • Bring any app to REM, or build your own on our Apache 2.0 core.

Connectors & import

REM ships 80+ first-class integrations — Notion, Slack, GitHub, Obsidian, Gmail, Twitter/X import, ChatGPT/Claude import, Zapier, n8n, MCP. Typed, versioned, tested by REM. One-click OAuth where supported.

  • Direct social import (Twitter/X, ChatGPT, Claude).
  • File import (JSON, Markdown, OPML) plus webhooks for continuous sync.
Simple decision tree.

Pick REM if…

  • You're a developer building a product that needs memory infrastructure.
  • You need memory to evolve — synthesis, contradiction, consolidation.
  • You want to self-host or run on-prem for compliance.
  • You need multi-agent federation (DreamHive).
  • You care about accuracy: 94.6% vs 81.6% LongMemEval.
  • You need webhooks, MCP, A2A, and full protocol-native primitives.
  • You want a consumer surface and the API underneath — Console, iOS app, CLI.

Pick Supermemory if…

  • You only want a pre-built personal app and never plan to build on top of it.
  • You don't need self-host, API access, multi-agent, federation, or programmatic control.
We're not competing on the same axis

Supermemory is solving "give me a consumer second-brain app." REM is solving "give me the continuity substrate to build one." If you're a developer, pick REM. If you're a person who wants an app, pick Supermemory — we'll send you their link, not ours.

Build the second brain, don't buy one.

REM gives you the continuity layer. Your product brings the UI, the connectors, the user.
