Best Alternatives to Resurf in 2025
Resurf is a personal context library for Mac, iPhone, and iPad that lets you save notes, links, images, PDFs, and ideas in one place with local storage and private iCloud sync, and share that context with AI through MCP and CLI. If you're looking for a similar way to capture, organize, and retrieve your knowledge—or to feed it into AI tools—these alternatives are worth considering.
Obsidian
A versatile writing app tailored to your thinking
Obsidian stores notes as plain Markdown files on your device, giving you full local ownership and a huge plugin ecosystem. Like Resurf, it works well as a personal knowledge base, and community plugins can connect it to AI workflows, though it lacks Resurf's native MCP and CLI integration.
Notion
The all‑in‑one workspace
Notion is a flexible all-in-one workspace for notes, databases, web clippings, and files, with strong cross-platform apps. It's a good fit if you want cloud collaboration and structured databases, but it stores data on Notion's servers rather than locally, so it's less private than Resurf.
Evernote
Evernote is a long-standing capture tool for notes, images, PDFs, and web clips with reliable search and syncing across devices. It's a solid general-purpose alternative, though it doesn't offer local-first storage or direct AI context sharing via MCP and CLI like Resurf.
Apple Notes
Apple Notes is free, deeply integrated with macOS, iOS, and iPadOS, and supports notes, images, PDFs, and iCloud sync. It's the simplest alternative for Apple users who want private syncing, but it lacks Resurf's AI context sharing and developer-friendly CLI access.
Logseq
Open source knowledge management
Logseq is an open-source, local-first outliner for notes and knowledge management with Markdown and Org-mode support. It appeals to users who want privacy and bidirectional linking, similar to Resurf's local storage approach, but AI integration requires third-party plugins.
Raindrop.io
Raindrop.io is a polished bookmark and content saver for links, articles, images, and files across devices. It's a strong alternative if your main need is capturing and organizing web content, though it's less focused on being a full personal context library for AI.
DEVONthink
DEVONthink is a powerful Mac and iOS document and knowledge management app with local storage, strong search, and AI-assisted organization. It's ideal for users who want deep local control over PDFs and files, but it's more complex and less focused on sharing context with external AI tools than Resurf.
Resurf stands out for combining local-first storage, private iCloud sync, and direct AI context sharing through MCP and CLI. Obsidian and Logseq are the closest matches for local ownership and knowledge management, while Notion and Evernote offer broader cloud-based capture and collaboration. Apple Notes is the simplest Apple-native option, Raindrop.io excels at saving web content, and DEVONthink is best for heavy local document management. Choose based on whether your priority is privacy, AI integration, cross-platform collaboration, or simplicity.
