Testing Claude’s Native Integration with Reminders and Calendar on iOS and iPadOS

Reminders created by Claude for iOS after a series of web searches.

Reminders created by Claude for iOS after a series of web searches.

A few months ago, when Perplexity unveiled their voice assistant integrated with native iOS frameworks, I wrote that I was surprised no other major AI lab had shipped a similar feature in its iOS apps:

The most important point about this feature is the fact that, in hindsight, this is so obvious and I’m surprised that OpenAI still hasn’t shipped the same feature for their incredibly popular ChatGPT voice mode. Perplexity’s iOS voice assistant isn’t using any “secret” tricks or hidden APIs: they’re simply integrating with existing frameworks and APIs that any third-party iOS developer can already work with. They’re leveraging EventKit for reminder/calendar event retrieval and creation; they’re using MapKit to load inline snippets of Apple Maps locations; they’re using Mail’s native compose sheet and Safari View Controller to let users send pre-filled emails or browse webpages manually; they’re integrating with MusicKit to play songs from Apple Music, provided that you have the Music app installed and an active subscription. Theoretically, there is nothing stopping Perplexity from rolling additional frameworks such as ShazamKit, Image Playground, WeatherKit, the clipboard, or even photo library access into their voice assistant. Perplexity hasn’t found a “loophole” to replicate Siri functionalities; they were just the first major AI company to do so.

It’s been a few months since Perplexity rolled out their iOS assistant, and, so far, the company has chosen to keep the iOS integrations exclusive to voice mode; you can’t have text conversations with Perplexity on iPhone and iPad and ask it to look at your reminders or calendar events.

Anthropic, however, has done it and has become – to the best of my knowledge – the second major AI lab to plug directly into Apple’s native iOS and iPadOS frameworks, with an important twist: in the latest version of Claude, you can have text conversations and tell the model to look into your Reminders database or Calendar app without having to use voice mode.

Claude’s Chat History and App Integrations as a Form of Lock-In→

Earlier today, Anthropic announced that, similar to ChatGPT, Claude will be able to search and reference your previous chats with it. From their support document:

You can now prompt Claude to search through your previous conversations to find and reference relevant information in new chats. This feature helps you continue discussions seamlessly and retrieve context from past interactions without re-explaining everything.

If you’re wondering what Claude can actually search:

You can prompt Claude to search conversations within these boundaries:

  • All chats outside of projects.
  • Individual project conversations (searches are limited to within each specific project).

Conversation history is a powerful feature of modern LLMs, and although Anthropic hasn’t announced personalized context based on memory yet (a feature that not everybody likes), it seems like that’s the next shoe to drop. Chat search, memory with personalized context, larger context windows, and performance are the four key aspects I preferred in ChatGPT; Anthropic just addressed one of them, and a second may be launching soon.

As I’ve shared on Mastodon, despite the power and speed of GPT-5, I find myself gravitating more and more toward Claude (and specifically Opus 4.1) because of MCP and connectors. Claude works with the apps I already use and allows me to easily turn conversations into actions performed in Notion, Todoist, Spotify, or other apps that have an API that can talk to Claude. This is changing my workflow in two notable ways: I’m only using ChatGPT for “regular” web search queries (mostly via the Safari extension) and less for work because it doesn’t match Claude’s extensive MCP support with tools; and I’m prioritizing web apps that have well-supported web APIs that work with LLMs over local apps that don’t (Spotify vs. Apple Music, Todoist vs. Reminders, Notion vs. Notes, etc.). Chat search (and, again, I hope personalized context based on memory soon) further adds to this change in the apps I use.

Let me offer an example. I like combining Claude’s web search abilities with Zapier tools that integrate with Spotify to make Claude create playlists for me based on album reviews or music roundups. A few weeks ago, I started the process of converting this Chorus article into a playlist, but I never finished the task since I was running into Zapier rate limits. This evening, I asked Claude if we ever worked on any playlists, it found the old chats and pointed out that one of them still needed to be completed. From there, it got to work again, picked up where it left off in Chorus’ article, and finished filling the playlist with the most popular songs that best represent the albums picked by Jason Tate and team. So not only could Claude find the chat, but it got back to work with tools based on the state of the old conversation.

Resuming a chat that was about creating a Spotify playlist (right). Sadly, Apple Music doesn't integrate with LLMs like this.

Resuming a chat that was about creating a Spotify playlist (right). Sadly, Apple Music doesn’t integrate with LLMs like this.

Even more impressively, after Claude was done finishing the playlist from an old chat, I asked it to take all the playlists created so far and append their links to my daily note in Notion; that also worked. From my phone, in a conversation that started as a search test for old chats and later grew into an agentic workflow that called tools for web search, Spotify, and Notion.

I find these use cases very interesting, and they’re the reason I struggle to incorporate ChatGPT into my everyday workflow beyond web searches. They’re also why I hesitate to use Apple apps right now, and I’m not sure Liquid Glass will be enough to win me back over.

Building Tools with GPT-5→

Yesterday, Parker Ortolani wrote about several vibe coding projects he’s been working on and his experience with GPT-5:

The good news is that GPT-5 is simply amazing. Not only does it design beautiful user interfaces on its own without even needing guidance, it has also been infinitely more reliable. I couldn’t even count the number of times I have needed to work with the older models to troubleshoot errors that they created themselves. Thus far, GPT-5 has not caused a single build error in Xcode.

I’ve had a similar initial experience. Leading up to the release of GPT-5, I used Claude Opus 4 and 4.1 to create a Python script that queries the Amazon Product Advertising API to check whether there are any good deals on a long list of products. I got it working, but it typically returned a list of 200-300 deals sorted by discount percentage.

Though those results were fine, a percentage discount only roughly correlates to whether something is a good deal. What I wanted was to rank the deals by assigning different weights to several factors and coming up with a composite score for each. Having reached my token limits with Claude, I went to GPT-o3 for help, and it failed, scrambling my script. A couple of days later, GPT-5 launched, so I gave that a try, and it got the script right on the very first try. Now, my script spits out a spreadsheet sorted by rank, making spotting the best deals a little easier than before.

In the days since, I’ve used GPT-5 to set up a synced Python environment across two Macs and begun the process of creating a series of Zapier automations to simplify other administrative tasks. These tasks are all very specific to MacStories and the work I do, so I’ve stuck with scripting them instead of building standalone apps. However, it’s great to hear about Ortolani’s experiences with creating interfaces for native and web apps. It opens up the possibility of creating tools for the rest of the MacStories team that would be easier to install and maintain than walking people through what I’ve done in Terminal.

This statement from Ortolani also resonated with me:

As much as I can understand what code is when I’m looking at it, I just can’t write it. Vibe coding has opened up a whole new world for me. I’ve spent more than a decade designing static concepts, but now I can make those concepts actually work. It changes everything for someone like me.

I can’t decide whether this is like being able to read a foreign language without knowing how to speak it or the other way around, but I completely understand where Ortolani is coming from. It’s helped me a lot to have a basic understanding of how code works, how apps are built, and – as Ortolani mentions – how to write a good prompt for the LLM you’re using.

What’s remarkable to me is that those few ingredients combined with GPT-5 have gone such a long way to eliminate the upfront time I need to get projects like these off the ground. Instead of spending days on research without knowing whether I could accomplish what I set out to do, I’ve been able to just get started and, like Ortolani, iterate quickly, wasting little time if I reach a dead end and, best of all, shortening the time until I have a result that makes my life a little easier.

Federico and I have said many times that LLMs are another form of automation and automation is just another form of coding. GPT-5 and Claude Opus 4.1 are rapidly blurring the lines between both, making automation and coding more accessible than ever.

Early Impressions of Claude Opus 4 and Using Tools with Extended Thinking

Claude Opus 4 and extended thinking with tools.

Claude Opus 4 and extended thinking with tools.

For the past two days, I’ve been testing an early access version of Claude Opus 4, the latest model by Anthropic that was just announced today. You can read more about the model in the official blog post and find additional documentation here. What follows is a series of initial thoughts and notes based on the 48 hours I spent with Claude Opus 4, which I tested in both the Claude app and Claude Code.

For starters, Anthropic describes Opus 4 as its most capable hybrid model with improvements in coding, writing, and reasoning. I don’t use AI for creative writing, but I have dabbled with “vibe coding” for a collection of personal Obsidian plugins (created and managed with Claude Code, following these tips by Harper Reed), and I’m especially interested in Claude’s integrations with Google Workspace and MCP servers. (My favorite solution for MCP at the moment is Zapier, which I’ve been using for a long time for web automations.) So I decided to focus my tests on reasoning with integrations and some light experiments with the upgraded Claude Code in the macOS Terminal.

Eddy Cue Causes a Stir for Google

2025 is shaping up to be the year of litigation for big tech. Apple’s been held in contempt and has an antitrust case on the horizon, Meta is in the midst of an antitrust trial, and Google is defending two antitrust lawsuits at once. Every one of these cases is a high-stakes challenge to the status quo, and collectively, they have the potential to reshape the tech industry for years to come.

The ultimate question for Google right now is whether it will be broken up. What will become of its ad tech business, and will it be forced to sell Chrome? That will be decided by the judges in those cases, but along the way, there are plenty of sideshow dramas worth keeping an eye on. This week, it was Google’s turn for a little litigation drama that was prompted not by a judge, but by none other than Apple’s SVP of Services Eddy Cue.

As part of Google’s search antitrust case, Cue testified yesterday that in April 2025, Google searches declined in Safari for the very first time. Cue’s testimony, which was reported on by Mark Gurman, Leah Nylen, and Stephanie Lai of Bloomberg, went on to explain that Apple is investigating AI search as an alternative to traditional search engines, noting that the company has had discussions with Perplexity.

Google’s stock immediately began to fall. By the close of trading, it was down around 7.5% and had caused enough concern internally at Google that the company felt compelled to release a one-paragraph statement on its blog, The Keyword, responding not to the testimony but to “press reports:”

Here’s our statement on this morning’s press reports about Search traffic.

We continue to see overall query growth in Search. That includes an increase in total queries coming from Apple’s devices and platforms. More generally, as we enhance Search with new features, people are seeing that Google Search is more useful for more of their queries — and they’re accessing it for new things and in new ways, whether from browsers or the Google app, using their voice or Google Lens. We’re excited to continue this innovation and look forward to sharing more at Google I/O.

It’s not news that Google Search is under threat from AI. However, Cue’s testimony under oath that Google searches in Safari are in decline is the first concrete evidence publicly shared that the threat is not just theoretical, which is a big deal.

Apple’s exploration of AI-based search is not terribly surprising either, but I do hope they cut a broader deal with Anthropic instead of Perplexity. I understand why Perplexity’s product is popular, but its CEO’s contempt for the open web and user privacy is something that I’d rather not see Apple perpetuate through a partnership.
