Resurf 2 personal context library for Mac iPhone and iPad with AI search and private local storage

Resurf Review: A Private AI-Powered Personal Context Library for Mac, iPhone & iPad

We save an enormous amount of information every day. Articles, screenshots, PDFs, notes, links, videos, voice recordings, images, research material, code snippets, ideas, and files can quickly become scattered across browsers, folders, cloud services, messaging apps, and note-taking applications.

The difficult part is often not saving information. The real challenge is finding and remembering it later.

This is the problem Resurf is designed to solve.

Resurf is a personal context library for Mac, iPhone, and iPad that gives users one place to capture, organize, search, read, annotate, and revisit the information they want to keep. The current Resurf 2 release was rebuilt as a native Swift application for Apple's platforms, with local-first storage and optional private iCloud synchronization.

Unlike many cloud-first productivity applications, Resurf is designed around the idea that your personal library should remain under your control. Your library can live locally on your devices, work offline, and sync through your own iCloud account without requiring a Resurf account.

But Resurf is more than a place for bookmarks. Its current feature set combines mixed-media capture, organization, full-text search, annotations, notes, voice transcription, optional AI assistance, and connections to AI agents through MCP and the CLI.

Let's take a closer look at what makes Resurf interesting.

The Big Idea Behind Resurf

At its core, Resurf is built around a simple concept: create a personal library of everything worth remembering.

Instead of maintaining separate applications for bookmarks, screenshots, research PDFs, notes, images, voice memos, and other reference material, Resurf allows these different types of content to live together.

The official website describes it as a "Personal Context Library." This is an important distinction because Resurf is not positioned purely as a note-taking app or bookmark manager. It is intended to preserve the broader context around the things you discover and create.

For example, a designer could save:

Website inspiration
Screenshots
Design notes
PDFs
Reference images
Voice ideas
Articles
Project files

A developer could keep:

GitHub pages
Documentation
Code
Technical articles
PDFs
Notes
Research material
AI-related references

A student or researcher could create Spaces for different subjects and keep articles, papers, screenshots, notes, and recordings together.

The result is a personal information library rather than a collection of disconnected files.

Resurf 2: A Complete Rewrite

One of the biggest developments in the current product is Resurf 2.

According to the developer, Resurf 2 is not simply an incremental update to the previous application. It was rewritten from scratch in Swift for Mac, iPhone, and iPad. The goal was to make the application faster, more responsive, and better suited to Apple's ecosystem.

The previous version used Electron. Resurf 2 moved to native Swift.

This change also made it possible for Resurf to expand properly onto iPhone and iPad.

The new version includes:

Native Mac application
Native iPhone application
Native iPad application
Private iCloud synchronization
Faster local search
Voice notes
On-device transcription
Highlights and comments
Stacks
AI assistant
Improved visual library
New capture methods

The developer says the rewrite was driven by reducing friction during capture. The idea is that if saving something takes too much effort, people simply stop saving things.

Capture Almost Anything

One of Resurf's strongest features is its broad support for different types of content.

The platform can handle:

Notes
Articles
Links
PDFs
Images
Screenshots
Videos
Audio
Voice notes
Code
YouTube content
GitHub pages
Files
Quotes
Highlights

This makes Resurf more flexible than a traditional bookmark manager.

You don't have to decide whether something is "a bookmark" or "a note" before saving it. You can simply capture it and organize it later.

The Inbox First workflow is designed around this idea.

You can save something immediately and worry about organizing it afterward. When you have time, you can process the Inbox and assign Spaces, tags, stacks, or other organization methods.

This can be especially useful for research-heavy workflows where dozens of potentially useful resources need to be collected quickly.

Capture From Mac, Chrome, iPhone and iPad

Resurf isn't limited to one capture method.

On Mac, users can capture information using shortcuts and browser-related tools. The Chrome extension allows users to save pages directly from the browser.

On iPhone and iPad, the system share sheet provides another way to send content into Resurf.

The official guides also mention widgets, the Action button, and Siri-related capture options on iOS and iPadOS.

This makes the workflow more natural because you don't always need to open Resurf before saving something.

The goal is essentially:

Discover → Capture → Organize later → Find again

Spaces, Tags and Stacks

Resurf provides several ways to organize information.

Spaces

Spaces are useful for larger areas such as:

Work
Research
Personal Projects
Writing
Design
Business Ideas
Learning

A single item can be associated with multiple Spaces, making the organization more flexible than a traditional folder structure.

Stacks

Stacks are designed for lightweight grouping.

Instead of creating a formal Space or carefully tagging every item, you can quickly group related captures together.

This makes Stacks useful when you need temporary or informal organization.

A Visual Library for Rediscovering Information

Another interesting aspect of Resurf 2 is its visual library.

The new interface uses a Pinterest-style masonry layout, displaying saved material using its natural proportions instead of forcing everything into identical boxes. Videos can also show a filmstrip when hovered over.

This matters because sometimes you remember information visually rather than through keywords.

For example, you might remember:

"I saved a screenshot of that website with the purple interface."

A visual library can make rediscovering that item much easier than scanning a conventional list of filenames.

Resurf also includes features such as Shuffle and its Resurface widget, which are designed to bring older saved material back into your attention.

Search Inside Your Saved Content

Saving everything is only useful if you can find it again.

Resurf 2 includes local full-text search powered by SQLite. The official documentation says search can work across titles, notes, article text, PDF content, OCR text, voice transcripts, comments, tags, Spaces, filenames, URLs, and other metadata.

This is much more powerful than searching only the names of saved links.

For example, if you remember a sentence from an article but don't remember the website name, searching for that text can help locate the original capture.

Likewise, text inside screenshots or PDFs can become useful for finding older information.

Read, Highlight and Annotate

Resurf isn't simply a storage container.

It also provides reading and annotation features.

Users can highlight parts of saved material and keep comments beside the source. This can be particularly useful when researching articles, reading PDFs, or collecting information for a project.

Instead of saving a document and then taking separate notes somewhere else, the notes and source can remain connected.

This creates a more useful research workflow:

Save → Read → Highlight → Comment → Organize → Find later

Voice Notes With On-Device Transcription

Resurf 2 also introduces voice notes.

Users can record thoughts before they disappear, and the application can transcribe those recordings on the device. The developer specifically says that the transcription can happen locally rather than sending the audio elsewhere for processing.

This can be useful when:

Walking
Driving, when safely possible
Brainstorming
Planning a project
Capturing quick ideas
Recording research thoughts

Instead of typing everything immediately, you can speak and return to the note later.

AI Features Are Optional

This is one of the most interesting parts of Resurf 2.

AI is available, but it isn't required for the core application.

The basic library, capture functionality, local browsing, and search can work without an AI account. Optional AI features can provide summaries and allow users to ask questions about their saved information.

Resurf 2 includes an Ask Your Library AI pane.

Instead of asking a general AI chatbot about the entire internet, the idea is to ask questions about the information you personally saved.

For example:

"What did I save about typography?"

or:

"Which articles did I save about AI agents?"

The assistant can work with your saved context and identify relevant material.

Bring Your Own AI Key

Resurf takes a different approach to AI usage by allowing users to use their own OpenAI API key for its AI features.

The developer explains that the AI pane uses the user's own OpenAI key and that the user can see what the AI usage costs.

This is useful for people who prefer a direct relationship with their AI provider rather than having another application manage the AI account.

Resurf also supports handing saved context to AI agents through MCP or the CLI on Mac. This opens the door to using your personal library as a context source for AI-powered workflows.

Privacy and Local-First Architecture

Privacy is arguably one of Resurf's biggest selling points.

The library is designed to remain local on the user's Apple devices. Resurf does not require an account, and optional synchronization uses the user's own iCloud.

The developer also explains that the library remains as ordinary files on the Mac, including Markdown notes and original images and PDFs.

This is important because it reduces dependence on a proprietary online database.

If you stop using the application, the underlying files remain accessible.

However, users should distinguish between the local-first core and optional AI functionality. When AI features are used, the relevant content can be sent to the selected AI provider. Resurf states that its optional OpenAI features use the user's own key.

Platforms and Requirements

Resurf is designed specifically for Apple's ecosystem.

Current supported platforms include:

Mac
iPhone
iPad
Chrome extension

The Mac application requires macOS 14.3 or later, while iPhone and iPad require iOS/iPadOS 17 or later. The Mac application supports both Apple Silicon and Intel Macs.

This Apple-focused approach is important to consider before choosing Resurf.

There is currently no Windows, Android, Linux, or web application.

Resurf Pricing

Resurf follows a different pricing model from many modern productivity applications.

The Mac version has a free tier that provides up to 50 captures and 4 Spaces.

After that, the current official pricing page lists one-time purchase options rather than a monthly subscription:

One-time license: $39 during the current offer, with 2 years of updates
Lifetime license: $79 during the current offer, with future updates
iPhone and iPad: Free and unlimited

The standard prices shown on the official page are $49 and $99 respectively, with the current discounted prices displayed as $39 and $79.

This no-subscription model could be attractive to users who dislike paying monthly fees for productivity applications.

Prices and promotional offers can change, so users should check the official pricing page before purchasing.

Who Should Use Resurf?

Resurf is particularly interesting for people who collect large amounts of information.

Researchers

Researchers can keep articles, papers, PDFs, notes, screenshots, and voice notes in one library.

Writers

Writers can collect references, quotes, articles, research material, screenshots, and ideas for future content.

Designers

Designers can save visual inspiration, screenshots, websites, images, references, and design notes.

Developers

Developers can save GitHub pages, documentation, code, technical articles, PDFs, and AI research.

Students

Students can create Spaces for different subjects and maintain research material in one searchable library.

AI Users

People who regularly use AI tools may find the personal context features particularly useful because saved information can become context for AI-assisted workflows.

What Resurf Does Not Offer

Resurf has some important limitations.

It is currently an Apple-focused product, so Windows and Android users cannot use native versions. There is also no web application.

Resurf is also designed as a single-person library rather than a collaborative workspace. There are no shared libraries or team collaboration features in the current release.

Another limitation is search.

Although Resurf provides powerful local full-text search, the current release does not offer semantic or visual-similarity search.

There are also no one-click importers for services such as mymind, Raindrop.io, or Anybox yet.

These limitations are worth considering before moving an existing information library.

Resurf vs Traditional Bookmark Managers

The biggest difference is the type of information Resurf is designed to hold.

A traditional bookmark manager is mainly focused on links.

Resurf is broader.

It can contain:

Links + Notes + PDFs + Images + Screenshots + Audio + Video + Voice + Files + Research

That makes it closer to a personal context library than a traditional bookmark collection.

The official comparison with Anybox describes Anybox as more focused on bookmark management, while Resurf is designed around broader mixed-media context.

Similarly, Resurf's comparison with Raindrop.io highlights its local-first architecture and its ability to search across a wider range of content.

Final Verdict

Resurf is an interesting personal knowledge and context management application for people who live inside the Apple ecosystem.

Its biggest strength is the combination of local storage, mixed-media capture, powerful full-text search, flexible organization, native Apple apps, optional private iCloud sync, and AI-assisted access to your own saved context.

The arrival of Resurf 2 makes the concept more compelling because the application is now native across Mac, iPhone, and iPad. The addition of voice notes, on-device transcription, AI assistance, MCP/CLI support, stacks, better search, and the visual library expands the product beyond a simple bookmark manager.

The biggest drawback is its platform limitation. If you need Windows, Android, Linux, or a browser-based application, Resurf currently isn't designed for that workflow.

But if you use a Mac, iPhone, or iPad and frequently collect articles, screenshots, PDFs, notes, links, research, images, audio, and other information, Resurf offers a compelling way to turn that scattered material into a private, searchable personal context library.

For users who want more control over their data and prefer a one-time Mac purchase instead of another monthly subscription, Resurf is especially worth considering.
