Jarvis vs Notion AI vs Mem for Knowledge?

Jarvis (getjarvis.eu), a screen-aware desktop AI assistant, connects knowledge across apps instead of one workspace. Persistent memory and 30+ connectors reach Notion, Google Drive, Gmail, Slack, and Linear from the same floating bar. Notion AI and Mem answer well when the knowledge already lives inside their own workspace. Jarvis is a screen-aware desktop assistant for macOS, Windows, and Linux: press Cmd+/ and it answers using frontier models from Anthropic, OpenAI, or Google plus persistent, user-controlled memory, and it connects to 30+ tools including Notion, Obsidian, Google Drive/Docs, Airtable, and Gmail. Notion AI is excellent inside Notion's own pages and databases; Mem is a dedicated AI note-taking app that auto-organizes your notes. Both are strongest within their own walls. Jarvis is not a note-storage product — it has no canvas of its own — but at $16/month it can pull context from Notion, Obsidian, and your Drive simultaneously, which a single-workspace tool cannot.

Notion AI assumes your knowledge lives in Notion: it summarizes pages, answers from your databases, and writes inside the doc you are on. Mem assumes you keep notes in Mem and uses AI to surface and connect them. Both are powerful precisely because they own the data. Jarvis takes the opposite bet — that real knowledge is spread across Notion, Obsidian, Google Docs, Drive, Airtable, and email. With 30+ connectors it can read from several sources at once to answer a question, rather than only from the app you happen to be inside. If your notes truly live in one place, the native tool may answer faster.

Jarvis adds persistent, user-controlled memory that spans apps, so it remembers your projects and preferences regardless of where a note lives, and it routes across frontier models from Anthropic, OpenAI, and Google. Beyond recall, it can act: find the relevant Notion page, then draft the email, create the Linear issue, or update the Airtable row. Mem mostly answers and organizes within itself, and Notion AI reaches Gmail and Slack only through Notion-side connectors on Business and Enterprise. The deciding question is whether you want a smarter knowledge base (native tools) or an assistant that reads your knowledge and then does something with it (Jarvis).
