Compare the actual client, sharing boundary and correction lifecycle rather than assuming one product is solo-only.
An assistant remembers last month’s launch date. A teammate changes the plan. The next useful question is not whether memory exists, but how the new decision reaches the right readers and what happens to the older record. Supermemory offers an API and a managed MCP workflow with team spaces. Consider HeyBrain for a maintained reference workflow, then test the same dated change in each candidate. A comparison should acknowledge shared capabilities before asking which setup fits your team. Method: primary vendor sources reviewed on 6 October 2026; no hands-on head-to-head benchmark. Diagrams and pilot stories are fictional evaluation examples, not screenshots, customers or measured results.
In a fictional launch pilot, share an approved date, then a dated replacement. Ask the same question from the permitted client and record the source edition used. A fresh confident answer is useful only if it reflects the accepted change.
List the exact material and readers for the pilot. Supermemory documents team spaces; evaluate their actual scope alongside the HeyBrain configuration you intend to use. Do not connect a private source merely because a setup flow offers it.
Supermemory is a candidate when its documented managed MCP/team-space workflow or memory API fits the clients you use. Compare actual setup and upkeep for your task; this is not a claim that every listed client behaves identically.
No. Its MCP documentation describes collaboration in team spaces with read/write access, as well as individual use.
Identify the exact space and client grants in your proposed workflow. Test a permitted reference and one excluded fictional item; neither a team label nor a diagram proves the boundary.
Supermemory’s product page distinguishes excluding memories from search from erasing database records. That distinction matters when defining retention requirements.
Write down whether your request is to stop retrieval, remove stored content or remove a source copy. Confirm the supported operation and its result for each candidate; this page offers no deletion-proof guarantee.
Supermemory describes derivations as part of its memory lifecycle. A derived conclusion should be evaluated differently from an explicit approved decision.
In the fictional launch pilot, include a question the references cannot settle. Record whether the answer distinguishes evidence from inference. Do not treat a helpful-sounding inference as a new source fact.
Begin with the smallest approved set that can answer a useful question. Keep unrelated private material out and retain the authoritative original.
Confirm the chosen input or connector and the work needed to keep it current. This comparison does not promise an automatic HeyBrain connection to every source or migration from another memory service.
| Attribute | HeyBrain | Supermemory |
|---|---|---|
| Primary choice | Evaluate a maintained knowledge-reference workflow | Memory API or managed MCP workflow |
| Shared access | Verify the actual identities and supported input path | Team spaces with documented read/write access |
| Lifecycle | Test a dated correction and retrieval outcome | Documented updates, derivations and forgetting |
| Retention check | Verify removal and retention requirements explicitly | Forgetting is described separately from database erasure |
| Pilot | An approved launch date, its correction and an unsupported question | The same fictional change exercise |
| Acceptance | Current evidence, excluded material and manageable upkeep | The same criteria; no performance benchmark reported |

Vendor documentation checked on 2026-10-06. These sources describe published policies and features; they are not independent tests of your configuration. The fictional pilot examples above are not measured results.
Supermemory distinguishes input documents from extracted memories and describes updates, derivations and forgetting. Its product page says explicit forgetting excludes selected memories from search while retaining records in the database.
Supermemory documents an OAuth-based managed MCP server, with team spaces and read/write access. Clients receive tools for memory search/capture and stored-document access.
Select fictional or approved references and confirm the receiving path before transferring anything. Keep the current service intact during the pilot.
Do not assume spaces, client grants, extracted memories or forgotten records map automatically to HeyBrain. Write a small mapping and stop rule before expanding the trial.
