Molecule Notes vs Roam Research
Daily notes and linked pages, in a workspace you can share.
A journal page for every day, [[links]] that gather every mention, and a graph of what you've connected. Invite people in and write in it together.
What a shared page carries with it
Sharing individual pages loads the rest of your graph's data in every visitor's browser. Roam only displays the page you shared, but a technically skilled visitor could dig out the others.
Roam gives you two ways to share. You can invite people to the whole graph by email, with read or edit access, or you can share a single page by link while the rest of the graph stays private. Roam's own help page is plain about what the second way costs: the visitor sees one page, but the rest of your graph's data travels to their browser with it.
Molecule Notes has only the first way. You invite people to a workspace, and there is no link that shares one page. To show someone part of your notes, you put that part in a workspace of its own and invite them to it.
That's a trade-off. Roam can put a single page in front of anyone with the link, and Molecule Notes can't. What Molecule Notes won't do is send the rest of your notes along with a page.
A workspace, not a page.
Invite people to a workspace by email. Everyone in it can open every page in it.
Writing together.
People in a workspace edit the same page at the same time, with each other's cursors on it.
Comments on the bullet.
Threaded, anchored to the bullet they're about, and resolvable.
| Feature | Molecule Notes | Roam Research |
|---|---|---|
| A page for every day | Yes: Every day has a journal page, and you can write onto any day. | Yes: You start on a page with today's date. |
| Links and backlinks | Yes: Every mention of a page gathers on it, under Linked mentions. | Yes: Linked References collect every mention of a page. |
| Block references | No: You link pages, not individual bullets. | Yes: Refer to any block by its ID, and edits reach every reference. |
| Graph of linked pages | Yes: A graph view of the links you make. | Yes: Graph Overview, with nodes you can move, zoom into and open. |
| Comments | Yes: Threaded, on the bullet they're about, and resolvable. | Yes: Discuss a block in a thread without editing it. |
| Sharing with someone else | Yes: Invite people to a workspace by email. No single-page link. | Yes: Invite people to the whole graph with read or edit access, or share a single page. |
| AI in the app | Yes: An agent you name on a line researches, and answers under it. | Yes: Semantic search that matches meaning. |
| MCP server | Yes: Your AI assistant can read, search and update your notes. | Yes: A hosted MCP server, a local one, and a CLI. |
| End-to-end encryption | No: Not offered. | Partly: Encrypted graphs, for new graphs only. Backups and exports aren't encrypted. |
| On your phone | Partly: A web app you can install on your phone. No native app. | Yes: Native apps for iPhone, iPad and Android. |
| Export | Partly: One page at a time, with Copy as Markdown. | Yes: Markdown, JSON, EDN or MessagePack. |
The habits you already have
Roam's idea is that it doesn't matter which page you wrote a note on: mention an idea, and every mention gathers on that idea's page. Molecule Notes is built on the same idea, because deciding where a note goes is what makes people give up on notes. It takes longer than writing the note.
So the day's page is where you write, and every note on it is dated without you doing anything. Type [[ and name a person, a book or a project, and that page gathers every mention of it, under Linked mentions. Nothing needs filing, and the graph view shows the connections you've made.
Some things are different. Molecule Notes links pages, not blocks, so there are no block references. Hovering a link shows the page it points at, and shift-clicking opens it in the margin beside the page you're on, where you can keep writing.
An agent you name on a line
Roam's AI work is real: semantic search that finds notes by meaning, a hosted MCP server, a local one, and a CLI. Molecule Notes has an MCP server too, so the AI assistant you already use can read your notes and update them.
Inside the app, Molecule Notes adds one thing more. Name an agent on a line and it goes to find out: it reads the pages around that line, searches the web, and writes what it found under your line. It answers when you ask. It never writes your notes for you.
Taking your notes back out
Molecule Notes stores your notes as bullets in a database, not as files on disk. Any page comes out as Markdown with Copy as Markdown, from the page itself.
There's no one-step export of a whole workspace in the app. An AI assistant connected over MCP can read every page and hand each one back as Markdown.
Bringing your Roam graph in
There's no import screen. Import runs through MCP: export your graph from Roam as Markdown, connect an AI assistant to Molecule Notes, and point it at the export. It writes the pages in bulk.
A page titled with a date, like 2026-09-13, is that day's journal page, so ask your assistant to retitle your daily notes that way and they land on their days. Block references have nowhere to go, so ask it to write the referenced text in their place.
