Why does my AI assistant forget everything the moment the session ends?
Context window is RAM, not storage, no window size survives a session restart. Every Cursor / Claude / Perplexity / personal-copilot user re-explains their preferences, project conventions, and personal context every single session. Cross-device identity is unsolved. Indie hackers building "AI assistants for X" hit this wall in week two.
Who has it: Founders building personal AI assistants, agent products, vertical copilots. Anyone shipping a multi-session AI product.
Evidence
Users describe an assistant that knows their codebase and style in one session, then greets them as a stranger in the next, so they rebuild the same context again and again.

Mem0 "Context Window Is RAM, Not Storage" (May 2026), Cloudflare Agent Memory launch (April 2026), Oracle developers blog "Agent Memory: Why Your AI Has Amnesia".Scoring breakdown
Existing players
- Mem0 · Best-in-class; YC-backed; but framework, not a drop-in product for end-users
- Letta (MemGPT) · Strong for agent memory; requires self-host + integration work
- Supermemory · Personal memory; one ecosystem, no cross-device identity story
- ChatGPT memory · OpenAI-only; doesn't help if you use multiple LLMs
What they are missing
An LLM-agnostic personal memory layer: install once, attach to Cursor + Claude Code + Perplexity + Notion AI + the chatbot of the day. Cross-device identity resolution (same person on phone + laptop). Decay scoring (which memories are still accurate). Exportable so the user owns it.
