The AI for work landscape is changing quickly.

As people discover and try new tools, they either spread the word or ditch one platform for another.

Just a few weeks after our Top 100 AI for Work March report, we see significant changes in the rankings of many AI platforms.

Especially the rapid rise of Claude and Microsoft Copilot is remarkable, as are new platforms entering the Top 100.

Let's dive in!


Generative AI for Work Crosses 3 Billion Monthly Visits

The Top 100 AI Tools for Work continues to grow.

From February to March, web traffic increased by 13%, while branded searches for the individual platforms added 17%.

In total, the Top 100 tools booked 3,217 billion visits versus 2,838 billion in February (+ 379 million). Branded searches, the amount of times someone searched for a particular tool, indicating it's popularity) rose to 263 million, up from 225 million (+ 38 million.)

The Competition for ChatGPT heats up (Hi, Claude!)

Speaking of the LLM category, there's good and bad news for ChatGPT.

With 15% growth from February to March, the major LLMs like ChatGPT, Gemini, and Copilot now account for 2,3 billion visits and 72% (+2%) of all AI for work platforms traffic.

More saliently, ChatGPT is losing some market share amongst the major GPTs to especially Claude and Copilot: ChatGPTs traffic as a percentage of all GPTs went down from 80% to 75% from February to March.

Google Gemini, which follows ChatGPT by some distance as the #2 AI for work tool booked a 37% gain as it grew from 316 to 433 million monthly visits.

But, let's be honest, all eyes really should be on Claude, whose rise is particularly noteworthy.

The LLM from maker Anthropic launched in March 2023, but as of last month didn't even crack the Top 10 of all AI tools for work.

Recent news of Claude being the #1 LLM as rated by users may have boosted awareness and interest, as the Gen AI platform surged 8 spots from #16 in February with 21 million visitors to #8 of all AI tools in March with 54 million visits, growing 161%.

This is especially impressive given that Claude isn't yet available in many countries.

Claude also surpassed Microsoft Copilot, which still boosted its use by 48% from 20 to 30 million, reaching the Top 10.

Finally, Mistral's Le Chat makes it into the overall Top 100 at 47 with 3.8 million monthly visitors, whereas it previously ranked outside of the top 100.

The Top 10 Looks Vastly Different

The Top 10 AI Tools for work booked a collective 2.6 billion visits and 188 million branded searches. The makeup of the top has shifted, mostly due to Claude and Copilot entering.

The Top 7 remains unchanged since last month:

1: ChatGPT (incl. Dall-E)

2: Google Gemini (ex Bard)

3: Canva Magic Design, one of the biggest winners of the Generative AI movement, gained 8% month-over-month. According to the platform, over 4 billion creations have been aided by AI.

4: Writing tool Quillbot grew by 11% from 56 to 62 million monthly visits, with its highly popular paragrapher, grammar checker, and summarizer in several languages. The platform widened the lead with competitor Grammarly, which despite a gain of 5% in monthly visits, lost 3 places and fell out of the top 10.

5: "Google killer" Perplexity.AI added an impressive 24%, growing from 50 to 62 million monthly visits. It still doesn't get close to Google (83 billion monthly visits) but the "if Google and ChatGPT had a baby" platform is clearly resonating.

6: GitHub Copilot, which helps 1.3 million programmers code better and faster – to the tune of a 50% increase in productivity, added 5% and grew to 46,710,000 visits.

7: Poe by Quora founder Adam D’Angelo, lets users chat with any of the major GPTs and create their own bots, grew 14% to 50 million monthly visits.

However, due to Claude and Copilot's rise, the remaining spots have shifted.

At 8, we find, as discussed above, LLM Claude, while the new number 9 is Microsoft Copilot.

Number 10 is the highly impressive (we can't stop using it at work) Suno.

FlexOS Research Top 100 Generative AI for Work Audio Tool

Suno is a 'prompt-to-song' AI audio generator, allowing anyone to make radio-ready hit songs.

Need an "HR anthem" for your next meeting? An ode to Company Culture? Then you'll love Suno.

With a simple prompt, you create a tailor-made tune. Try it out: "Create a Swift-style song about how we love our new HRIS." Suno's new competitor Udio went viral on social media, but barely registered on traffic or searches in the past month – which surely will change in April.

The gain of Claude, Copilot, and Suno is the loss of the remaining entrants in March's Top 10:

  • Image generator Leonardo AI, which offers designers tools to fine-tune their creations to the tune of  4.5 million images a day, lost 1 percent and dropped to #14.
  • Grammarly, the second writing aid after Quillbot, now drafts email replies, revises text, and writes copy, but after gaining 11% from December to February, growth slowed to 5% and the platform landed on #12.
  • Midjourney. known for itsimpressive and photorealistic visuals dropped one spot and landed on #11, with a still-impressive growth of 6%.

The full Top 10 of April 2024 looks as follows:

Image Generators Remain the Most Popular (and Competitive) Category – By a Stretch

Like last month, image generators and editors represent 21 of the Top 100 AI platforms for work, the largest category by a mile.

And without a doubt, this number would have been much higher if we had included more consumer-type AI image platforms.

Only Video Generators come close, with 13 (+1) entrants in the Top 100. 

This means that Image Generators are popular, but also that tools in this category have an outsized competitive set to deal with.

For a deep-dive in the image category, see last month's report.

The remaining categories by the number of tools present in the Top 100 are:

Mistral, Suno, Claude and others see dazzling growth

A number of platforms grew ahead of the curve in the past month, led by Mistral, Suno, and Claude.

Here are the platforms to take note of, skipping the ones already mentioned above:

1. Mistral Le Chat

Mistral is gaining steam, but doesn't seem to understand what it is

Only last month, I highlighted Mistral's recently launched Le Chat as the one missing from the major ranks, but this month it takes the top spot amongst the fastest gainers.

Mistral, which is the "European ChatGPT," grew 518% from February to March and added 3,141,865 to its previous 606,135 monthly visits. It also doubled branded searches to 3.8 million, highlighting significant noterietay.

4. Pi

Pi AI, please stay!

Well, this is bittersweet, to say the least.

Perhaps on the back of the news that Pi's (previous) parent company Infliction was "purchased" by Microsoft, the friendly AI chat platform grew by 53% to 6.2 million visits, while increasing searches by 46% to 1.1 million.

The "takeover" news came with unclear reports on whether Pi will survive or not. Given its newfound popularity, I hope it will stick around. It's a joy to use!

9. Typeset / SciSpace


Confusingly named "SciSpace" (for 'Science' and 'Workspace') but hosted on Typeset.io, this platform is another research tool worth looking into besides Consensus.

According to its makers, including founder Saikiran Chandha, SciSpace has "the vision to bring readers, researchers, faculty, publishers, and universities under one roof and provide an open space where they can discover research, discuss findings, connect and collaborate, and disseminate research." 

The platform grew by 34% to 6 million monthly visits clocked over half a million branded searches, a lift of 57% versus February.

The Bottom Line: AI for Work Top 100 in April 2024

If you were like us and thought the world of AI started and ended with ChatGPT, hopefully, this data review will open your mind.

With so many tools, some tailored to specific roles and workflows, it’s no wonder that OpenAI’s Sam Altman said he expects a one-person unicorn to be possible. 

Let me know which platforms you end up using. Similarly, if you find an AI for Work tool that’s missing from this overview, please reach out.

Let’s make work more human by offloading repetitive, non-value-adding tasks to AI. It’s one way we can create a happier future of work


We reviewed over 400 AI tools referenced in news, online directories, and lists to create this overview. 

Our starting point is to take usage data from the only standardized source, Similarweb. While no publicly available data source is perfect, Similarweb has scored well in comparative benchmarks. 

Based on their March data, we made our calculations as follows:

  • For web traffic, we took the March monthly visits.
  • For branded searches (as a proxy for true popularity), we multiplied the percentage of the March web traffic by the percentage of branded searches.
  • For the % gained (or lost), we took the March monthly visits and compared it to the February traffic.

We focused on company, enterprise, and individual contributor-focused platforms that bring Generative AI to the workplace. Platforms with an outspoken consumer focus (which may be used at work too, like Character.AI, the number #4 in our AI Top 150.)

Reversely, there may be platforms here that have real utility for work, but consumers also use them. Just look at ChatGPT, which students highly use. We aim to showcase all the great AI technology that can help people work smarter, so we still included such platforms. 

Finally, because of the data source (Similarweb web traffic and branded searches), it also means that huge tools that millions use, but are administered by a few (like most HR tech) are lower in the ranking.

We may have overseen some tools, but we believe that this is a comprehensive selection. If we erroneously left out any platforms, we invite companies to submit their listing for our next report.

We excluded tools that existed before Generative AI unless they were significantly transformed. 

For platforms with fairly significant AI features, like Canva, Notion, and Figma, we applied an estimated percentage of their total traffic that could be attributed to their AI features. 

Often, this is based on statements from the company, like Canva, noting how people have produced over 4 billion AI creations over the past year. Otherwise, we took a standard 5–10% of total web traffic.

Where applicable, like in the case of ChatGPT and Grammarly, we used the 'app' version of the website, which is where the actual usage happens. 

Whenever a platform had multiple use cases besides general GPTs, we listed it under its apparent most-used case, analyzed from search data or sub-URL popularity. This is why Canva is under Image Generators, even though it also has a significant presence in the video and presentation generator categories. (Psst, Canva, feel free to contact us with the real data ;))

All of the above paints an obvious picture: this is very much an imperfect view of AI tools' popularity, driven by our curiosity. 

For some web tools, the proxies we've taken for usage could be solid, as web traffic and search dominance likely reflect how often people use a tool like Quillbot, which all takes place on the website.

For others, like software you can download (Descript, the Office version of Microsoft Copilot) and tools that mostly get used through plugins (Grammarly) or apps, this is only a tertiary indication of potential popularity.

In future months, we'd love to include real usage numbers, as reported by these platforms, to create better rankings.
