Frequently Asked Questions

Can Lucy OS1 replace Notion AI?
They serve different needs. Notion AI is strongest for generating and editing content within Notion pages. Lucy OS1 is strongest for voice conversation, daily planning, and persistent memory that works outside of any single app. If Notion is your primary workspace, Notion AI is more integrated. If you want voice-first AI that works everywhere, Lucy OS1 is the better fit.
Does Notion AI have memory across sessions?
Notion AI accesses the content in your Notion workspace, so any notes you have written there serve as persistent storage. However, it does not have automatic cross-session AI memory — it does not recall what you said in a conversation last week unless you wrote it down in Notion. Lucy OS1's memory is automatic and structured.
Does Lucy OS1 work with Notion?
Lucy OS1 can discuss and reference content you share verbally, but does not have a direct Notion integration. If you keep notes in Notion, you can share key points with Lucy in conversation and it will remember them. A Notion integration is something many users have requested.
What is better for a solopreneur — Notion AI or Lucy OS1?
Many solopreneurs use both. Notion AI handles the writing and organising within Notion. Lucy OS1 handles the thinking work: morning planning, email triage, calendar awareness, and the kind of sustained voice conversation that helps clarify thinking. Together they cover different parts of the workday.
