Fabric vs. Roam Research

Last updated April 2026

Roam Research pioneered bidirectional linking and the "tools for thought" category. Fabric takes the same underlying idea, that your content should be connected, and does it automatically across all file types with AI. Roam asks you to build the graph. Fabric builds it for you. Here's how they compare.

Comparison table

What is Roam Research?

Roam Research is an outliner-based note-taking tool built on a graph database. You write in a bullet-point structure, create bidirectional links between notes, and the graph view shows how everything connects. It launched in 2020 and defined the "tools for thought" category. Since then, development has slowed and many users have moved to free alternatives like Obsidian and Logseq that offer similar linking features. Roam costs $15/month with no free tier. It has no built-in AI, limited mobile support, no API, and a narrow integration ecosystem.

What is Fabric?

Fabric is an AI workspace that combines file storage, note-taking, search, tasks, collaboration, and publishing.

The Fabric Memory Engine automatically extracts, enriches, and maps relationships between everything you save. Where Roam requires you to manually create connections between notes, Fabric understands your content and builds connections automatically, across all file types, not just text.

Key differences

Manual connections vs automatic understanding

Roam's core idea is that you create links between notes, and over time those links form a knowledge graph you can navigate and query. It's a powerful concept. It also requires sustained effort. Every connection exists because you made it. If you forget to link something, it's invisible to the graph. The system is only as good as the work you put into maintaining it.

Fabric's Memory Engine maps relationships automatically. You save content. Fabric extracts it, enriches it, and figures out what's related without you creating a single link. This works across all content types, not just text notes. A PDF connects to a saved article connects to a meeting recording, without you manually linking any of them.

If you enjoy the ritual of linking and building a graph by hand, Roam offers that. If you'd rather the system handle it, Fabric does.

AI

Roam has no AI. No assistant, no summarisation, no Q&A over your notes. What you put in is what you get out, connected only by the links you've created.

Fabric has a built-in AI assistant that works across your entire library. It answers questions, summarises documents, transcribes audio and video, generates meeting recaps, and takes actions inside the app. Multiple models, available at every pricing tier. The AI understands your content. Roam stores it.

Content types

Roam is text-first. It's an outliner. You can embed images, PDFs, audio, and video, but they're attachments, not indexed content. You can't search inside an embedded PDF or find a moment in an embedded video. The graph only knows about what you've written and linked in text.

Fabric handles all content types natively. PDFs, images, video, audio, documents, slides, spreadsheets, ePubs, links, emails. Everything is automatically extracted and searchable. The AI understands all of it. If your knowledge exists in more than bullet-point notes, Fabric covers it.

Search

Roam has full-text search across your notes. It finds keywords in what you've written.

Fabric searches by meaning. Semantic search finds content even when you describe it differently from how it was written. Visual search finds similar images. Colour search finds assets by palette. In-document search goes to the page in a PDF, the slide in a deck, the timestamp in a video. Cross-platform search pulls from Google Drive, Notion, and Dropbox alongside your Fabric library.

Pricing

Roam costs $15/month with no free tier. A 31-day trial is available. The Believer plan is $500 upfront for five years, which is a significant commitment to a product with an uncertain development trajectory. For context, Obsidian and Logseq offer similar linking features for free.

Fabric includes AI at every tier. [Insert Fabric pricing details.] The free tier offers more functionality than Roam's trial.

Platform support

Roam is primarily a web app. Mobile support is limited. There's no dedicated desktop app with offline capabilities.

Fabric is available on web, iOS, Android, desktop, and as a Chrome extension. Full mobile apps. If you need to capture and access content from anywhere, Fabric covers more ground.

Collaboration

Roam added multiplayer editing, but it's limited. No annotations, no shared drives, no threaded comments, no team workspaces with permission controls.

Fabric supports real-time co-editing, annotations on any content type, threaded comments, in-context chat, and shared drives. For teams, Fabric has the tools. Roam is fundamentally a single-user product.

Integrations and data portability

Roam has no public API and a limited integration ecosystem. Exporting your data is possible (JSON, Markdown), but the graph structure doesn't transfer cleanly to other tools. This creates lock-in. Moving away from Roam means losing the connections you've spent months or years building.

Fabric connects to Google Drive, Notion, Dropbox, Gmail, GitHub, and more via API, MCP, CLI, Zapier, and direct integrations. Your content lives in standard file formats. There's no proprietary graph structure that traps your data.

Development pace

Roam defined a category in 2020. Since then, development has slowed noticeably. Many features users have requested remain unshipped. The community has shrunk as users migrated to Obsidian, Logseq, and other tools that offer similar core features at lower (or no) cost. Paying $15/month for a product with an uncertain roadmap is a consideration.

Fabric is actively developed with regular feature releases across all platforms.

When to use each

Use Fabric if you want your content connected and searchable without building the connections yourself. You work with diverse file types beyond text notes. You want AI that understands your library. You need collaboration, publishing, or cross-platform search. You want a product that's actively developed and available on all platforms.

Use Roam Research if you specifically value the outliner format and manual bidirectional linking, and you're willing to pay $15/month for it. Roam's approach to networked thought is opinionated and some people prefer it. If you haven't tried it yet, Obsidian and Logseq offer similar linking features for free.

Why people move from Roam Research to Fabric

They wanted connections without the work. Building a graph by hand is satisfying until it becomes a chore. Fabric's automatic relationship mapping gives you connected content without the maintenance.

They needed AI. Roam stores what you write. Fabric understands it. The ability to ask questions about your content, get summaries, and have the AI reference your saved material changes how you work with your notes.

They had more than text. PDFs, meeting recordings, images, design files. Roam doesn't handle these as searchable, connected content. Fabric does.

They worried about the product's future. Slow development, shrinking community, $15/month with no free tier. Many Roam users had already moved to Obsidian before discovering Fabric offered automatic connections instead of manual ones.

They needed to collaborate. Roam is a solo thinking tool. When work involves other people, it doesn't scale.

FAQs

Can I import my Roam Research data into Fabric?

Roam exports in JSON and Markdown. You can bring your notes into Fabric. The bidirectional link structure won't transfer as manual links, but Fabric's Memory Engine will map relationships between your content automatically, so the connections rebuild themselves in a different form.

Does Fabric have bidirectional links like Roam?

Fabric maps relationships between content automatically through the Memory Engine. You don't create links manually. The system understands what's related based on the content itself. The approach is different: automatic understanding rather than manual linking.

Is Fabric free?

Fabric has a free tier with limited storage and AI.

Is Roam Research still being developed?

Roam is still active, but development has slowed compared to 2020-2021. Feature releases are less frequent, and the community has contracted as users have moved to alternatives. The $15/month price with no free tier remains unchanged.

Does Roam have AI?

No. Roam has no built-in AI features. Fabric includes an AI assistant across multiple models at every pricing tier.

Which is better for research?

Roam was designed for researchers who build knowledge graphs through manual linking. Fabric is designed for people who collect diverse research material and want it understood and connected automatically. If your research is primarily text-based note-taking with interlinked ideas, Roam's outliner is purpose-built for that. If your research involves PDFs, articles, images, recordings, and other media alongside notes, Fabric handles the full picture.
