Most teams pick an AI memory product by the model it uses. The more important question is where the memory physically lives.
A cloud memory layer is convenient — until you realize every decision, customer note, and internal context your team produces is now sitting in someone else's database. You traded ownership for convenience.
A local-first layer keeps the store on your own hardware:
- Raw data never leaves the intranet unless you explicitly choose to share it.
- Consolidation and forgetting run on machines you control.
- Sharing is opt-in, per document, per person.
You still get retrieval-augmented memory. You just stop handing the crown jewels to a vendor by default.
I am building HyperMarrow, a local-first memory system for AI agents and coding assistants. The docs and download are here: https://hm.qianshi.cool/api/v2/dl?from=devto.
If you had to pick, where would your team's memory store physically live?
(Disclosure: I build HyperMarrow, the local-first memory system described above.)

the trade most posts skip is cold-start and memory eviction. a local model that stays loaded gives you flat latency every time, but the moment you swap models or run out of ram you eat a multi-second reload. cloud hides that behind a pool. which side bites you depends on how many models your app needs hot at once.
