Most people don't need AI to do their jobs for them. They need AI to help them get through their work faster. That's one reason AI adoption continues to grow. According to Microsoft's 2024 Work Trend Index, 75% of global knowledge workers now use generative AI at work. From drafting documents and summarizing meetings to automating repetitive tasks, AI is helping people spend less time on busywork and more time on meaningful work.

Of course, not every AI tool delivers on its promises. Some become part of your daily workflow. Others get used once and forgotten. At Readdle, we’ve been building productivity apps since 2007, and that experience has taught us that AI is most useful when it removes real friction, not when it’s added as a gimmick. That’s the thinking behind the AI features in apps like PDF Expert, Spark, Calendars, and Documents.

What are AI productivity tools?

AI productivity tools are applications that use artificial intelligence to help you complete specific tasks faster and with less manual effort. Unlike traditional software that requires you to perform every step yourself, AI-powered tools can generate content, analyze information, identify patterns, make recommendations, and automate portions of your workflow. Many are designed to act as assistants, helping you move through tasks more efficiently rather than starting from scratch.

Readdle's top 4 AI productivity tools for work

If you're new to AI productivity tools, you don't need to overhaul your entire workflow. Some of the most effective AI tools are built into activities you're already doing every day. These four tools can help you save time immediately without requiring a major change to how you work.

1. PDF Copilot: Best for working with PDFs

Reading through lengthy PDFs can be one of the most time-consuming parts of the workday. Whether you're reviewing research reports, contracts, client proposals, training materials, policy documents, or meeting notes, finding the information you need often means scrolling through dozens of pages.

PDF Copilot uses conversational AI to help you interact with PDFs more naturally. Instead of manually searching for information, you can ask questions about a document and receive answers based on its contents. You can also generate summaries, identify key takeaways, explain complex sections, and quickly locate specific information within a file.

For example, a consultant could ask for the main recommendations in a 50-page client report. An HR professional could quickly review an employee handbook for policy information. A student could summarize a research paper before an exam. Rather than reading every page line by line, PDF Copilot helps you get to the information you need faster.

Key features include:

  • AI-powered document summaries. 
  • Natural language questions and answers. 
  • Extraction of key insights and action items. 
  • Translation and conversion in 80+ languages. 
  • Quick navigation through large PDFs.

2. Spark +AI: Best for managing email and meetings

Email is still one of the biggest time drains at work. Not just writing messages, but keeping up with conversations, responding quickly, and staying organized across threads.

Spark +AI is designed to help you move through email faster and with less friction. It can draft emails from scratch, rewrite messages based on tone, shorten long responses, and turn rough ideas into polished communication. Instead of starting from scratch, you can generate a first draft in seconds and refine it from there.

It also helps you turn real conversations into reusable email templates, making it easier to standardize replies for common scenarios like client follow-ups, internal updates, or recurring requests. 

One of the most useful features is meeting notes, which expands Spark beyond email. It can transcribe meetings, summarize key points, and extract important takeaways so you don’t have to take notes or rely on memory. The key benefit is that it works without bots joining your calls and integrates with any meeting platform, so it doesn’t interrupt the flow of your meetings.

If you use AI tools like Claude or ChatGPT in your workflow, Spark also offers a CLI that lets AI agents like Claude Code and Cursor work with your email, calendar, contacts, and meetings. You stay in control by choosing each account’s access level, from read-only to triage or sending, and ready-made skills for workflows like morning standups, meeting prep, and weekly digests make it easy to get started.

Key features include:

  • AI-generated email drafts with AI auto-drafts. 
  • Email rewriting and tone adjustment. 
  • +AI Meeting Notes for transcription and summaries.
  • Works with any meeting platform (no bot required). 
  • Creation of reusable email templates from real conversations.
  • Spark CLI for connecting AI agents to your inbox and calendar.  

Download Spark for iOS and Mac, Spark for Windows or Android and start spending less time on email. 

3. Calendars by Readdle: Best for planning and scheduling

Your calendar is supposed to save you time, but keeping it up to date can feel like a job of its own. Typing in event details, copying dates from emails and flyers, hunting for a free slot, and checking for conflicts all add up over the course of a week.

Calendars AI is an assistant built into Calendars by Readdle that lets you manage your schedule just by describing what you need. Ask it to create or update an event or task, and it prepares a draft for you to review before anything lands on your calendar. It can also find time for you, whether that’s a block for focused work, a window to meet with someone, or space for something personal, all matched against what’s already on your schedule.

One of the most useful features is turning images into plans. Share a screenshot, photo, or file, like a school timetable, an event flyer, or a scanned schedule, and Calendars AI pulls out the dates, times, names, locations, and deadlines, then turns them into event and task drafts. Instead of entering everything by hand, you just review and confirm.

It also helps you see what’s coming. You can ask quick questions like when your next meeting is, and the Weekly Brief gives you a higher-level view of the week ahead, surfacing conflicts, deadlines, birthdays, and unusual events first so nothing slips through a busy schedule.

Throughout, you stay in control. Calendars AI suggests and drafts, but you decide what gets added. Your data isn’t used to train the AI and stays on your device.

Key features include:

  • Natural language event and task creation.
  • Screenshot, photo, and file to calendar drafts.
  • Smart free-time finder for focus time and meetings.
  • Answers to questions about your schedule.
  • Weekly Brief highlighting conflicts, deadlines, and special events.

Calendars AI is currently in early access for Calendars subscribers. Request early access here.

4. Smart Insights by Documents: Best for Fast Summaries of Files and Articles

There’s always something waiting to be read: a report before a meeting, a research paper for a project, or an article you saved last week and still haven’t opened. Often, you don’t need to read every page. You just need to know what’s inside and which parts deserve your attention.

Smart Insights is Readdle’s AI summarization feature, available in the Documents app on iPhone and iPad and on the web at Documents.io. Whichever you use, you get an executive summary of the main idea, the key takeaways, and a bias analysis that shows the tone and possible leanings of the source. That last feature is especially useful when you’re reading news, opinion pieces, or research where how information is presented matters as much as what it says.

In the Documents app

In the Documents app, Smart Insights sits right next to the files you already manage. Open a PDF, text file, image, or link, tap Extract Insights, and you get the key points in seconds. It works with reports, papers, guides, ebooks, notes, and articles from the web.

You don’t have to start inside the app, either. Come across a long article while browsing on your iPhone? Send it to Documents from the iOS Share menu and extract insights there. The same works with supported content from other apps, so you can get the main points from a file someone sent you without changing how you save and organize things.

Once you have a summary, you can copy, share, or export it, whether that means saving research notes, sending a summary to a colleague, or deciding which parts of the original to read in full. Your file and its summary stay together, so it’s easy to go back to the source.

On the web at Documents.io

If you’re working on a computer, or just don’t want to install anything, the same technology is available in your browser through three dedicated tools:

  • AI Summarizer: An all-purpose summarizer for PDFs, text files, and images (PNG, JPG, and WEBP).
  • AI PDF Summarizer: Built for PDFs like reports, contracts, guides, and ebooks, with main points, answers, and action items.
  • AI Article Summarizer: Made for long-form reading such as articles and research papers, with the option to ask follow-up questions.

The web tools work on desktop and mobile browsers. You can try them for free with 3 files per account.

For example, a manager could get the gist of a 40-page report before deciding which sections need a closer read. A student could pull the main ideas out of course materials before an exam. A researcher could check the perspective behind a source before citing it.

Key features include:

  • Executive summaries and key takeaways in seconds.
  • Bias detection to show the tone and perspective of a source.
  • Extract Insights for PDFs, text files, images, and links in the Documents app.
  • Summarize content from other iPhone apps via the iOS Share menu.
  • Copy, share, or export summaries.
  • Browser-based summarizers for files, PDFs, and articles on Documents.io.

Download Documents app to summarize PDFs, files, and articles with Smart Insights on your iPhone or iPad, or try it in your browser.

Final Thoughts

Thousands of AI tools are available right now, but only a few will stick in your daily workflow. The ones that do tend to share a simple trait: they reduce effort inside tools you already use every day. That’s why the best way to approach AI productivity isn’t to chase trends, but to focus on friction. Where are you spending too much time reading, writing, or searching? That’s where AI can help most.
