Roam Research vs Heptabase

Roam Research is the pioneering outliner that made bidirectional links and daily notes famous; Heptabase is a visual learning tool where notes are cards you arrange and connect on infinite whiteboards. Here’s how they compare on pricing, platforms, linking, search, capture and collaboration — and how to decide between them.

What is Roam Research?

Roam Research kicked off the modern “tools for thought” wave in 2020. Every note is an outline of blocks; any block can be referenced, embedded and linked from anywhere else, and the daily-notes page makes capture frictionless. Bidirectional links — see every place a page is mentioned — were its signature idea, since adopted by nearly every tool in this list.

Roam runs as a cloud-hosted graph with web, desktop and mobile apps, and supports multiplayer shared graphs. It costs $15/month or $165/year (no free plan beyond a 31-day trial), with a $500 five-year “Believer” plan. Development has visibly slowed since its heyday — recent years brought mostly backend work rather than new features — which is worth weighing against its still-excellent core outlining model.

What is Heptabase?

Heptabase is for people who think spatially. Notes are cards; understanding happens by laying them out on infinite whiteboards, drawing connections, grouping into sections and mindmaps, and annotating PDFs alongside. It’s a deliberate take on learning deeply — less “capture everything” and more “make sense of what you’re studying” — and nothing else in this list matches its canvas experience.

Cards support Markdown, backlinks, tags with table views, and journals, so it still functions as a complete note system off the whiteboard. It runs on desktop, web and mobile with offline support and cloud sync. There’s no free plan (7-day trial); 2026 pricing is AI-credit-tiered — Pro at $8.99/month (annual) with Premium tiers above it for heavier AI use.

Where Roam Research shines

• The block-reference model remains best-in-class: reference, embed and remix any bullet anywhere, with transclusion that keeps everything in sync.
• Daily notes as the default entry point suits journaling and interstitial note-taking.
• Powerful queries and roam/js customization for advanced users.
• Multiplayer graphs allow real shared workspaces.

Worth knowing: At $15/month with no free plan, it’s among the priciest tools here. Development pace has slowed markedly, and the mobile experience lags competitors. It’s cloud-hosted and proprietary, with no local-first storage for standard graphs.

Where Heptabase shines

• The best whiteboard-native note experience available — cards, sections, mindmaps and connections feel built-in, not bolted on.
• PDF annotation on the same canvas as your notes suits deep study workflows.
• Tags double as tables, giving light database views over cards.
• Solid offline support with sync across desktop, web and mobile.

Worth knowing: No free plan — only a 7-day trial. Collaboration is limited to shared whiteboards; it’s primarily single-player. Spatial organization is the point — if you don’t think in maps, the canvas is overhead rather than insight.

Which should you choose?

Choose Roam Research if:

• Your thinking is outline-shaped and block references are central to how you write.
• You live in daily notes and build structure bottom-up.
• You’re already invested in a Roam graph and its query workflows.

Choose Heptabase if:

• You learn by arranging ideas spatially and drawing the connections yourself.
• You study from PDFs and want annotation living next to your notes.
• A visual overview of a topic matters more to you than fast capture.

A third option: Dexi

If what you actually want is one searchable place for notes, bookmarks, newsletters and RSS — with tags, @mentions and [[wiki links]] that organize themselves as you write, semantic search that finds ideas even when the words don’t match, and an MCP server so Claude and other AI assistants can work with your notes directly — take a look at Dexi. It’s free for up to 1,000 notes, with no app to install.
