Literature review workflow
Map a Literature Review Without a Reference Manager.
Two hundred PDFs in Zotero. A folder structure that made sense in March. A literature gap you can feel but can't see — because a list will never show it to you. Map your sources spatially, surface the clusters, find the gap your thesis fills.
Why this matters
A reference manager catalogs; a mind map synthesizes.
The Thesis Whisperer puts it bluntly: "This is not a tool problem. I say this after trying and discarding almost every digital tool on the market." What she means: the problem isn't where you store the PDFs — it's that storing the PDFs is the easy part. The hard part is seeing how the arguments fit together, where the contradictions live, and where your contribution belongs in the conversation. A list of 200 titles will never show you that.
Dumbnote is built for the synthesis step — not the cataloging step. Each source becomes a node you can tag with a page number, paste a quote inside, and drag into the thematic cluster where it belongs (or leave floating until you decide). The shape of your literature emerges spatially, the way the matrix method emerges on paper — except the matrix can hold quotes, images, and the running marginalia you'd otherwise lose in your offline mind mapping workflow.
And when the literature stops fitting a tree — when Bjork cites Karpicke who contradicts Carpenter and they all loop back to a 1988 Sweller paper — open the same document as a Graph. Force-directed clusters surface the connections a hierarchical view buries.

For your work
For the Lit Review You Can't See the Gaps In.
If you've ever read a paper at 11pm, written a note, and lost the note by morning — this workflow is for you. Mewburn calls it "information indigestion": the gap between the amount of literature in your reference manager and the amount of literature in your head. The cure isn't more storage; it's spatial structure you can scan in a glance.
The float-node pattern is the unlock. Mewburn writes that "if you put all the papers into your reference manager from the beginning, you'll get attached" — and that attachment makes culling impossible. Float nodes are the opposite: a parking lot for sources you haven't committed to. They sit on the canvas, off the tree, until you decide. The ones that never find a home are the ones you don't cite — and you delete them without the psychological cost of "letting go."
How it works
How to map a literature review
-
Start with your research question in the center
One node, one line. The actual question, not the title of the chapter. "RQ: does spaced repetition outperform massed practice for STEM learners?" — that level of specificity. Everything else will radiate out from this.
-
Add sources as nodes — author, year, page
For each source, create a node labeled "Author Year" and attach a page-number tag chip. Don't worry about completeness; you can always pull bibliographic metadata from Zotero later. The goal here is structure, not citation formatting.
-
Paste the quote inside the node
Expand any source node into a rich card. Paste the specific quote you'd cite, plus the page number, plus your marginal note ("contradicts the Roediger position"). The whole context lives with the source — no flipping back to the PDF when you sit down to draft.
-
Group into themes — let some sources float
Drag sources into thematic branches. Crucially, leave the unplaced ones as float nodes — off the tree — until you decide. The float pile IS the literature you haven't synthesized yet, and that's honest information about where the work still is.
-
Switch to Graph mode to find the clusters
When the themes start linking to each other — citations across branches, arguments that loop back — open the same document in Graph mode. The force-directed layout pulls clustered sources together and pushes contradictions apart. The shape of your literature becomes visible.
-
Look for the gap
The gap is where the nodes are sparse — the unanswered question between two clusters, the contradiction nobody resolved, the citation pattern that points to a missing paper. That gap is your contribution. Mark it with a sticky note: "this is where my thesis sits."
-
Export to Markdown when you draft
When the map is done and the gap is named, export to Markdown. The hierarchy becomes your lit-review section's scaffolding. Each branch becomes a paragraph cluster. Drop it into Word, Pages, LaTeX — your final draft inherits the structure of your thinking.
Common questions
Questions visitors ask before they try it.
Do I need to delete my reference manager?
No. Use Dumbnote alongside it. Zotero or Mendeley still does the citation-formatting work at draft-time. Dumbnote is the spatial synthesis layer between "I have 200 PDFs" and "I have a coherent literature review." The two tools serve different stages of the workflow.
How long does it take to set up?
Zero setup. Open dumbnote.app/mindmap in a browser and start mapping. No template selection, no plugin installation, no Dataview queries, no Templater scripts. The 30 days some researchers spend "building their Obsidian vault" — that's 30 days you can spend reading papers instead.
Will my literature map sync to my other devices?
Only if you want it to. By default, it lives in your browser's local storage on the device where you created it. To move it, export the standalone HTML file or the Markdown — both are portable. Optional Google Drive sync is available, but the default is local-only.
What about citations? Can I generate a bibliography?
Dumbnote isn't a citation manager. The pattern in practice: tag each source node with a Zotero/Mendeley citation key (e.g. "@bjork2011"), then on draft-out, your reference manager handles the formatted bibliography. Dumbnote does the thinking; Zotero does the formatting.
Can I share my literature map with my advisor?
Yes. Click Share — Dumbnote generates a link your advisor can open in any browser to see the same map in real time. End-to-end encrypted P2P — nothing's on a server, so your unpublished work stays unpublished. When the session ends, no copy lingers in anyone's cloud.
Does it work for systematic reviews / PRISMA workflows?
It supports them but doesn't enforce them. For PRISMA, you'd use Dumbnote for the conceptual synthesis side (themes, contradictions, gaps), and a dedicated tool like Covidence or Rayyan for the screening/eligibility tracking. The two complement; one doesn't replace the other.
