Market intelligence vs. the field · Updated May 2026
| MemoryIntelligence™ | Supermemory | MemPalace | Rewind | Notion AI | Manual (Notion/Obsidian) | |
|---|---|---|---|---|---|---|
| Core approach | Semantic pipeline → Unified Memory Objects. Raw content → structured, receipted meaning. | API-first flat key-value memory store. No semantic conversion. | Beautiful personal knowledge journal. Consumer-focused curation. | Screen + audio recording → searchable history. Passive capture only. | LLM layer on top of existing Notion docs. No external capture. | Manual paste and tag. Fully user-maintained. |
| Receipted provenance | Yes — SHA-256 H₁ hash at capture. Every UMO has a verifiable receipt. | No | No | No | No | No |
| Semantic pipeline | 7-stage: Normalize → Extract → Enrich → Parse → Embed → Validate | Embedding only (no structure) | Basic tagging + embedding | Transcription + keyword index | LLM summarization only | None — manual tagging |
| Multi-user isolation | Full ULID-scoped user isolation, RLS, 4-layer security (May 2026) | API key scoping only | Single user only | Single user only | Workspace-level only | N/A |
| API / SDK | REST API + Python/JS/iOS SDKs. Enterprise ingest wiring in progress. | Strong REST API. Developer-first. | No public API | Mac app only, no API | Notion API only | N/A |
| Target customer | B2B teams (5–200 people), enterprise ingest, knowledge-intensive work | Developers building memory into apps | Individual knowledge workers, students | Individual professionals, Mac users | Teams already using Notion | Individuals, small teams |
| Connector strategy | MI is the filter, not the connector. Customers bring their own pipes. | Building integrations (maintenance burden) | Manual import | Screen recording (passive) | Notion-only (walled garden) | Manual only |
| Self-cleaning memory | Deduplication + version conflict detection in pipeline | No — grows unbounded | Manual archive | Rolling 3-month window | Manual cleanup | Fully manual |
| MemorySpace exists but not polished. somewhere-house is the internal pilot. | Minimal — developer-focused | Strong — best consumer UX in market | Good Mac app, familiar | Familiar Notion interface | Varies by tool | |
| Pricing model | TBD — enterprise contract + per-seat API likely | Usage-based API credits | Freemium consumer | $20/month consumer | Included in Notion plans | Tool cost only |
| Funding / stage | Pre-seed, 5-person team, building | $3.5M seed (Apr 2026) | Bootstrapped / undisclosed | $10M+ Series A | Part of Notion ($10B+ valuation) | N/A |
| Our verdict | Unique on receipts + pipeline. Win on provenance. Build on UX. | Closest API competitor. Watch closely. Differentiate on receipts + B2B. | Not a threat. Different market. Learn from their UX. | Different motion (passive vs. active). Not a direct competitor. | Walled garden. Win by working everywhere they don't. | This is who we're replacing. The status quo. |
What this means for Somewhere
Our moat
Receipted provenance is unique in the market. Nobody else SHA-256 hashes at capture and returns a verifiable receipt. This is the trust layer enterprise buyers need and nobody else has. Lead with it.
Biggest gap to close
Consumer UX. MemPalace has the best UI. Rewind has the most familiar flow. MI's interface (MemorySpace + somewhere-house) needs a meaningful UX upgrade to convert non-technical users. Griffen and Gabbie are the test.
The status quo is the real competitor
Most teams are using Notion + manual paste as their "memory." That's who we're actually displacing. The pitch is not "we're better than Supermemory" — it's "we replace the burden of manual knowledge management."
Supermemory watch
They have funding and are moving B2B. They'll try to build structure on top of their flat store. We need to ship the enterprise ingest wiring (5 CLI tasks) and the SDK before they get there. Timeline: 4 weeks.
Don't build connectors
Connector strategies (SharePoint, Notion, Google Drive) become maintenance prisons. Every competitor who goes this route slows down. Our decision: be the filter, not the pipe. Let customers bring their own connectors.
Demo weapon
Open somewhere-house. Search for anything. Show the receipt hash. Ask "can any of these do that?" Nobody can. The receipt is the demo. Every sales conversation should end with a live receipt being shown.
