1. ChatGPT AI app/ ai chatbot

ChatGPT was launched by OpenAI, an AI and research company, in November 2022 and has generated quite a buzz since then. ChatGPT had 100 million active users just two months after its launch.

ChatGPT is a natural language processing tool powered by advanced generative AI. It can understand human language and respond conversationally.

The NLP language model can answer user questions and help with tasks such as writing an email, a poem, a piece of code, etc. Users are also asking ChatGPT to write essays, create a simple app, write Excel formulas, summarize content, write cover letters, translate text in multiple languages, etc.

ChatGPT is trained on vast textual data on the internet, including websites, books, articles, etc., using a combination of supervised and unsupervised machine learning techniques.

ChatGPT can give instant answers on almost every topic on the Internet and offers advice, creative inspiration, professional input, and learning opportunities.

ChatGPT on the web is available for free as it is still in the feedback-collection and research phase. A paid version, ChatGPT Plus, is also available on a $20/month subscription with perks like faster response times, access to the internet through plugins, etc.

The free ChatGPT uses GPT-3.5 LLM (large language model), while ChatGPT Plus offers access to the advanced GPT-4 model by OpenAI.

In January 2024, OpenAI unveiled their GPT Store to ChatGPT Plus, Team and Enterprise subscribers. The GPT Store is the place where users can find useful and popular GPTs — tailored versions of ChatGPT designed to help people with specific tasks in their day-to-day activities.

OpenAI also made available the ChatGPT iOS app in May 2023. The app can sync conversations, supports voice input, etc. From late July 2023, the ChatGPT app for Android devices is available on Google Play.

2. Grok AI chatbot/ AI app

In December 2023, Elon Musk’s xAI startup launched Grok, a conversational generative chatbot claimed to have a sense of humor and the ability to answer intricate questions with wit. 

Currently, Grok is available in beta version for X Premium+ subscribers in the United States only. The company promises that the Grok-1 model powering the much-talked-about chatbot will be evolving with ‘each passing week’ and offers users to join the Grok waiting list.

The tool received its name after the verb ‘to grok’ Robert Heinlein used in his sci-fi novel Stranger in the Strange Land. To grok is to understand an observed object so deeply that the observer merges with it. 

True to its name, one of Grok’s distinctive features is the real-time knowledge of the world due to direct access to X, formerly Twitter. This fact probably implies that the tool is always ‘in the loop’. It should be noted, however, that the training data used for the release version of Grok-1, according to the model card, comes from the internet up to Q3 2023. The card says that training data was also provided by AI Tutors.

There are a bunch of interesting numbers behind Grok-1 coming from a series of evaluations that the tool’s developers conducted using standard machine learning benchmarks. The model showed remarkable results, surpassing ChatGPT-3.5 in its compute class and only being beaten by models that had been trained on significantly larger amounts of data and compute resources like GPT-4.

While the new tool seems to be progressive and innovative, it still has imperfections common for generative AI. In particular, the xAI team admits that Grok can hallucinate.

3. Bing AI/ AI search engine

In February 2023, Microsoft announced its new version of the Bing search engine with an AI chat feature powered by the same technology as ChatGPT, GPT-4.

The Bing AI chat supports ChatGPT as the default search experience, which provides ChatGPT access to the entire internet and information on current events. With OpenAI integration, Bing web traffic increased by 15.4%.

The AI chat app offers complete answers to users that can be summarized for better clarity. Users get an improved and interactive chat interface for complex conversations such as planning a trip itinerary, etc. Bing AI is also capable of creative writing, such as interview preparations, essay writing, etc.

Microsoft has completely updated the user experience of the Edge browser with AI technology. Edge now offers two main features: chat and compose.

The Edge sidebar can be used to summarize a lengthy text with key takeaways, and the chat feature can be used to answer related questions.

The compose feature can write new content for users based on user prompts. Users can also update the tone, length, and format of the text content.

Microsoft Bing AI is now available for everyone and without a waitlist. According to Microsoft, Bing has grown to 100 million daily active users, and the daily installations of the Bing mobile app have increased 4 times since its launch.

4. Alexa virtual assistant/ Conversational AI app

Alexa, also called Amazon Alexa, is the AI-powered virtual assistant from Amazon. It was first used with Amazon Echo and Amazon Echo Dot smart speakers. However, it is now available on various platforms like Android and iOS.

Alexa uses voice queries, machine learning, natural language processing, computer vision, the Wolfram programming language, etc., to offer services like voice interaction, music playback, etc.

It can create to-do lists, set up alarms, stream podcasts, and play audiobooks. Moreover, Alexa can provide real-time information on weather, traffic, news, sports, etc.

Many devices that use Alexa let users activate Alexa via a wake word. Other devices like Android or iOS are only just catching up with this feature.

You can use Alexa on PCs like Windows and Mac, and it only requires a few simple steps to set it up. Some PCs allow hand-free activation of Alexa, whereas others require you to click the Alexa icon.

68.2% of smart speaker users in the US use Amazon Echo, an Amazon device with Alexa. Moreover, more than 100,000 smart home devices are supported by Alexa.

5. Siri/ AI virtual assistant

Siri, the famous virtual assistant from Apple that doesn’t need too much of an introduction, is one of the most popular AI apps. This AI-powered virtual assistant is available on all the major Apple platforms, e.g., iOS, iPadOS, macOS, watchOS, tvOS, and audioOS.

Siri uses voice queries and a natural language user interface (UI) to function, and it can make phone calls, send text messages, answer questions, and offer recommendations. It delegates requests to several Internet services. Moreover, Siri can adapt to users’ language, searches, and preferences.

The popularity of Siri is expected to grow in the coming years. As of 2024, 84.2 million people in the US are predicted to use Siri as their voice assistant. Siri, as one of the market leaders, holds 36% of the voice assistant technology market share.

The information available at the time of writing indicates that Siri will be available on Apple’s platforms only and not on Android or Windows. This is related to Apple’s strategic preferences.

6. Otter AI/ AI app

Otter.ai uses artificial intelligence to develop speech-to-text transcription applications. Otter.ai apps allow users to document automatic meeting notes with real-time transcriptions or recorded audio. Users can use Otter AI chat in meetings to ask questions and get instant answers.

Netflix members view hundreds of millions of hours of content every day. Machine learning also helps Netflix refine its catalog of TV shows and movies by analyzing characteristics that make content successful among the audience.

Other Top Trending AI Tools

It is always hard when writing a top 10 list to pick between so many great contenders. Given how hot the AI market is right now, and how we get so much feedback asking why we didn’t include such and such technology, we have decided to include a list of notable mentions of the top AI tools out there that we couldn’t fit into the top 10 AI apps.

Microsoft Copilot for Windows/ AI tool

Copilot is an artificial intelligence tool that helps with tasks such as writing code, code testing, documenting existing code, answering questions, creating images, etc.

While GitHub Copilot was launched in late 2021 with real-time auto suggestions in the code editor, Microsoft announced they are actively working on integrating Copilot into other areas like Windows and Microsoft 365 services.

Microsoft has announced Copilot as the new AI personal assistant for Windows 11. Users can ask Copilot to answer questions, summarize text, create images, etc. They could also ask Copolit to perform actions on Windows 11, like changing the screen theme, taking a screenshot, etc.

Microsoft is ending the support for the Cortana AI app as a personal assistant on Windows starting in late 2023. Cortana is currently supported by a range of devices, including Windows Mixed Reality, Microsoft Band, iOS, Android, and Windows mobile devices, Alexa, iPad, Android tablets, etc.

FitnessAI/ AI-powered fitness tool

FitnessAI was developed by OpenAI, the company responsible for ChatGPT. Released in 2018, it is an AI-powered fitness tool designed to optimize workout routines.

It employs machine learning algorithms to personalize exercise plans for users. By analyzing individual preferences, goals, and physical attributes, FitnessAI tailors workout regimens to maximize efficiency and results.

The technology utilizes data from its extensive database, encompassing various exercises, techniques, and fitness strategies. Users input information such as their fitness objectives, available equipment, and past workout experiences, enabling FitnessAI to generate custom routines. A really nice added touch is that the platform adapts these plans over time by learning from user feedback and performance data.

By intelligently processing user inputs and considering individual goals, FitnessAI creates workout regimens designed for maximum efficiency. Users can now bypass generic routines and see their routine gain from increased customization as the app adapts and evolves, tracking progress and making adjustments in real time.

The company claims to have mapped 5.9 million workouts, including 40,000 weight lifts, in order to create as accurate a model as possible.

Utilizing a mix of supervised and unsupervised machine learning techniques, FitnessAI’s recommendations are backed by data from a wide range of fitness sources. This comprehensive approach ensures that users receive guidance that’s both scientifically sound and tailored to their specific needs and goals.

FitnessAI is available on both Android and iOS. The app’s free version provides an enticing taste of what FitnessAI has to offer, while the premium subscription unlocks a host of advanced features.

Synthesia AI/ AI tool

Synthesia AI was released back in 2018. It is another advanced OpenAI artificial intelligence application. It focuses on video content generation.

FaceApp applies filters and effects that can change a person’s appearance, age, and gender, and even simulate different hairstyles and makeup looks. It set a new standard for self-transformation and image editing when it was launched, which is the main reason credited for its enormous success worldwide.

FaceApp AI offers a range of features in both its free and premium subscriptions. While the free version provides ample tools for creativity, the premium subscription unlocks a set of additional filters and effects.

According to statistics published on BuisnessofApps.com, “FaceApp generated $80 million revenue in 2022, $30 million more than in 2021.” The application “had an estimated 33 million users who access the app at least once in 2022.

Lensa AI/ AI photo editing tool

Developed by Prism Labs, and released back in 2016, Lensa AI uses advanced AI algorithms to enhance and retouch portrait photos. Lensa AI is able to harness the power of AI-driven visual analysis to allow even the least photography-savvy people to achieve professional editor-like results.

Lensa uses powerful artificial intelligence algorithms to retouch portrait images according to the user’s requirements. It is able to adjust features such as hair, skin, and eyes, as well as clothing and background elements.

While there is a free trial version (only lasts 1 week) of the app available on both Android and iOS, users are required to pay a subscription of $35.99 USD per year plus an additional fee for generating avatars. This pricing structure is arguably why the app’s number of users hasn’t reached the stratosphere. However, the number of users is still healthy and growing steadily.

Lensa recommends that people submit around 20 selfies to ensure the best portraits. These can include a wide variety of backgrounds and facial expressions, etc.

Seeing AI/ AI tools

Seeing AI is another Microsoft AI. This artificial intelligence application is to help redefine accessibility for visually impaired individuals.

At its core, Seeing AI offers an impressive range of features that cater to diverse needs. It features a text recognition feature that is powered by OCR (Optical Character Recognition) technology to help visually impaired people by reading text aloud. This function is incredibly useful for reading books, signs, labels, digital screens, etc.

The object recognition function uses the device camera to enable it to identify and then describe objects that it recognizes. This allows visually impaired people to understand their surroundings better. Examples include identifying currency denominations to distinguishing between products on a store shelf.

The app’s facial recognition feature can describe facial emotions and characteristics, allowing the user to once again better understand the people around them and their interactions.

Seeing AI, like all artificial intelligence and machine learning applications, is in its infancy. Accuracy has already been vastly improved since its original launch, something that promises better user satisfaction the more the app is able to learn.

Ask AI/ AI tools

Ask AI is a ChatGPT-like chatbot that essentially fulfills all the same roles. It is relatively recent to the marketplace so has yet to prove itself or make much of a dent into ChartGPT’s role at the top.

According to its website, “Ask’s tag-less AI technology analyzes customer communications, revealing the customer voice in one sentence insights that show you what to focus on.” The app is able to deal with both structured and unstructured data, which is a big positive for individuals and companies that are wishing to train Ask on their own data pools.

While anyone can use it, the company’s website seems to be orientated towards making this a powerful business tool that will allow companies to extrapolate insights.

Replika AI/ Personal chatbot companion

Replika AI is an interesting take on the chatbot craze. Rather than being a general-purpose chatbot, Replika AI is designed to be a friend who is tailored specifically to each individual user.

Users are able to create their own avatars and engage in conversation with their own AI friends. Replika AI learns from interactions meaning that it adapts to users’ preferences over time.

The goal of this AI is to be more human than human, meaning that users can rely on it no matter what type of person they are and what interests and needs they might have according to their own personality.

One of Replika AI’s standout features is its ability to remember previous conversations, allowing for continuity and a sense of an almost actual emotional connection.

This feature enhances the user experience, as the AI can reference past discussions, making conversations feel more natural and personalized.

The emotional component is where Replika AI shines. It’s designed to explore human relationships and offer emotional support and companionship, making it appealing to users seeking empathetic conversations.

The AI’s ability to engage in discussions about feelings, emotions, and personal experiences can be quite remarkable, offering a sense of comfort to users. Many Replika users have found a companion to share their feelings, celebrate wins, trade weird internet memes, etc.

According to Replika iOS and Android app descriptions, “Your chat is a safe, judgment-free space. It’s just you and your Replika. If you’re feeling down, or anxious, or you just need someone to talk to, your Replika is here for you 24/7”.

However, ethical concerns related to emotional dependency on AI companions should not be overlooked. While Replika AI provides a supportive environment, it’s essential for users to maintain awareness that the AI’s understanding of emotions is fundamentally different from human comprehension.

Replika is available on Oculus, Android, and iOS. Basic interactions are free for Replika users. Users need to opt into one of Replika’s subscription models to join millions talking to their own personal chatbots via more enhanced features.

Wombo AI/ AI art tool

Wombo AI transforms users’ photos into animated renditions of themselves that appear to sing popular songs. The app uses advanced facial recognition and animation techniques to map facial expressions to musical lyrics.

The app’s intuitive user interface enhances its accessibility, making it easy for users to upload images and select songs. The real-time preview feature ensures that users can see the animation before finalizing the creation, which adds an element of control and customization.

Younger users, in particular, have swarmed to Wombo AI thanks to the fun-natured videos that it produces. Being able to see yourself singing along to literally any popular song in a matter of seconds has made this a highly appealing artificial intelligence app.

Wombo AI is available on both Android and iOS as well as the through the Web application.
