Some second-brain apps build the AI in and pick the model for you. Koru keeps your notes on your device and lets you choose: connect Claude, Claude Code or another MCP-compatible tool when you want one.

Your draft shouldn't stall because the train went into a tunnel. In Koru, every note opens, edits and saves on your device, online or not. Free and open source.

If "is Notion safe" is still on your mind: Notion's advisory is about a vendor incident, not a breach of Notion's own systems. Still, it's fair to ask where AI chat transcripts go. In Koru, you choose the AI, and notes live on your devices.

Evernote lists Starter at $99 a year in the US (1,000 notes, 20 notebooks) and Advanced at $249.99 a year. Personal and Professional are retired. Prices through Apple or Google may differ. Koru is free, open source, and imports ENEX:

If you use Notion on a plane or a bad connection, only the pages you marked for offline are there. In Koru, the whole workspace already lives on your device. There's nothing to download first.

[Koru @korudotdo]

Evernote stores notes in its cloud, with offline access in the apps. Koru starts the other way: notes and docs live on your devices, not our servers, and they work offline first. Sync between your devices is peer to peer and end-to-end encrypted.

You can move a Notion workspace into Koru without signing in to anything. In Notion, export as Markdown & CSV (you get a .zip). In Koru, choose Import, then Notion, and pick the zip, or drop it in. The import runs offline.

If your Evernote archive is bigger than 1,000 notes, the Starter plan will not fit. Koru is free and open source, with no plan cap on how many notes you keep. Notes live on your devices and work offline.

To delete Notion AI chat history: open Chats with Notion AI in the sidebar, click the ••• menu on a chat, then Delete. Deleted chats skip Trash. Notion says they're retained for 30 days by default before permanent deletion. Enterprise owners can change that window.

Mermaid in Koru goes past flowcharts. Sequence diagrams and pie charts draw natively right inside your note, update as you edit the text, and work offline like everything else.

Notion AI is built into the product. In Koru, AI is something you choose: you bring the model you already use, and notes stay on your devices. Our built-in MCP server, koru-mcp, lets compatible AI tools read those notes when you want them to.

Leaving Evernote? Export each notebook as an .enex file from the Evernote desktop app. In Koru, choose Import, then Evernote, or drop the files in. The import runs offline on your computer.

Searching how to turn off Notion AI? On Business or Enterprise, an organization owner can disable it per workspace under Manage organization, then Manage workspaces, then enabled features. The AI chat tab then disappears. On Free and Plus, Notion says that tab stays.

Evernote Starter is capped at 1,000 notes and 20 notebooks. Over the cap, Evernote says you can still view and edit existing notes, but you can't create new ones until you're back under the limit.

@robkramson @NotionHQ I guess the only safe option is local first, keeping your notes and AI subscriptions local.

[Koru @korudotdo]

@marsh_tu If you export your data from Notion, you should be able to import it in @korudotdo, then your notes are local and you can use your own AI subscription.

[Koru @korudotdo]

@ebiken True it can happen to anyone. An alternative would be local notes with local AI.

[Koru @korudotdo]

@shonyan777 An alternative is to keep your notes local and use your local AI subscription, would love if you try us out.
