Fermeon syncs AI memory across ChatGPT, Claude, Gemini

Cross-platform AI memory is a crowded bet, and Fermeon is entering just as the major platforms are closing the gap with native memory features.

• –Core pitch is a single "vault" that follows you across AI platforms — useful for power users who bounce between Claude, ChatGPT, and Gemini daily
• –"Spotlight" feature claims to detect your current stack and fill in context gaps automatically, which is the most interesting differentiator
• –Cloud storage connectors (Google Drive, Notion, OneDrive) add context from beyond chat history, nudging this toward a personal knowledge layer
• –Direct competition from OpenMemory/Mem0 (open-source, already supports the same platforms) and MemoryPlugin is significant
• –Platform-native memory (Claude's free tier, ChatGPT memory) is gradually eroding the core value prop for single-platform users — the cross-platform angle is the only moat
