Free Access to Google Bard

As a new offering by Google, Bard bot is currently available to test for free without any login or account required. It is still in limited preview but expected to be released more widely soon to all Google users.

Limited Availability of Heypi

Heypi by Anthropic provides an AI assistant chatbot focused on safety and ethics. However, access is currently limited to approved beta testers only. Wider release plans have not yet been announced publicly.

Comparing Pricing and Free Versions of Leading Chatbots

When evaluating which chatbot to use, an important consideration is whether payment is required or a free version is available. Let's compare the pricing options for access across ChatGPT, Bing Chat, Perplexity AI, Claude AI, Google Bard, and Heypi.

The good news is that all these AI chatbots offer access without payment. ChatGPT, Perplexity AI, and Bing provide free tiers with subscription upgrades available. Meanwhile, Claude AI, Google Bard, and Heypi are completely free with no paid offerings at this time.

Language Models Powering the Chatbots Capabilities

Behind every chatbot is an AI language model that processes inputs and generates human-like responses. Each platform utilizes different proprietary models with unique capabilities.

The free ChatGPT relies on the GPT 3.5 model, while paid ChatGPT Plus applies the more advanced GPT-4. Bing Chat and Perplexity AI also leverage OpenAI's GPT-4. Claude AI uses its own ClaudeAI-1M model. Google Bard relies on LaMDA 2 and Heypi utilizes the Anthropic-1 proprietary model.

Comparing Text Prompt Size Limits Across Chatbots

The amount of text that can be input to an AI chatbot significantly impacts its usefulness across potential applications. Let's examine the maximum prompt size limits for ChatGPT, Bing Chat, Perplexity AI, Claude AI, Google Bard, and Heypi while highlighting variance where found.

Through testing, the free ChatGPT platform accepted text inputs up to approximately 31,000 characters before providing an error that the prompt is too long. Bing Chat clearly states a limit of 4,000 characters. Perplexity AI allowed text prompts up to about 9,200 characters before also complaining of excessive length.

Claude AI boasted the highest limit by far, accepting a whopping 352,000 characters of input text without issue. Google Bard capped input around 10,000 characters in testing. Finally, Heypi had the smallest size allowance at just 1,000 characters.

Comparing Image Recognition Capabilities

The ability to analyze and understand uploaded images provides a major enhancement to an AI chatbot's versatility. However, direct image processing requires completely different technical capabilities compared to text understanding. Let's see how these platforms compare at recognizing image content.

Right away we find that ChatGPT lacks any ability to directly view or interpret images. On the other hand, Bing Chat provides robust image recognition powered by Azure computer vision, with detailed analysis on uploads. Perplexity AI and Claude AI also fail to recognize images directly.

Google Bard offers some basic image captioning and classification, though accuracy remains limited. And Heypi does not accept image uploads at all with its text-only interface. So for visual content, Bing Chat is the clear winner at this time.

Reviewing Image Creation Abilities Across Chatbots

Taking the opposite approach from image recognition, some AI chatbots can automatically generate new images based on text prompt inputs alone. This can be incredibly useful for quickly illustrating ideas, concepts, or designs through the chatbot itself.

Once again we find that ChatGPT lacks any direct capability for image creation given its core language model foundation. However, Bing Chat leverages the DALL-E model to produce high quality images matching text descriptions. The other chatbots - Perplexity AI, Claude AI, Google Bard, and Heypi - all fail to generate images from prompts.

So for image creation powered by AI, Bing Chat dominates with robust Generative capabilities via DALL-E integration natively into the platform.

Comparing Web Access Capabilities

The ability for an AI chatbot to access information on the public internet greatly impacts its usefulness in providing accurate, up-to-date responses. We tested the skill of answering a simple "who is the CEO of Twitter" question across all platforms.

We found that ChatGPT and Claude AI lacked any ability to access online information, instead relying solely on pre-trained data from months past. This led to outdated name responses. Meanwhile Bing Chat, Perplexity AI, Google Bard, and Heypi all answered correctly by tapping into current data online.

So while ChatGPT and Claude may offer wide knowledge, only some chatbots can supplement with live internet access to provide truly timely and correct info.

Reviewing Languages Supported By Each Chatbot

If English isn't your native language, the number of languages supported becomes key in determining an AI chatbot's usefulness for your needs. Let's compare how many languages are enabled across ChatGPT, Bing Chat, Perplexity AI, Claude AI, Google Bard, and Heypi.

Impressively, ChatGPT, Bing Chat, and Google Bard support 100+ languages powering their conversational abilities. Perplexity AI enables 30+ languages. Claude AI only supports English at this time.

And Heypi also focuses on English exclusively in its current beta iteration. So for multilingual capabilities, ChatGPT, Bing Chat, and Google Bard are leading the pack by far.

Voice Chat Abilities: Speaking, Listening, and Synthesis

While text-based interactions enable wide applications for AI chatbots, the ability to handle voice input and output vastly improves natural engagement. Direct speech conversation creates new hands-free possibilities as well.

Among these platforms, only Bing Chat supports full voice interaction with speech recognition to text and text-to-speech synthesis. Google Bard provides text-to-speech voice outputs but does not interpret speech input.

And ChatGPT, Perplexity AI, Claude AI, and Heypi focus solely on text exchanges without any voice capabilities at this time. So Bing Chat is the winner for realistic vocal conversations today.

Media Analysis Features Comparison

Uploading documents beyond just images further increases the versatility of an AI chatbot. Several platforms advertise analysis features for PDFs, ebooks, and other file types. We tested these claims by uploading an 8.6MB PDF file.

Perhaps unsurprisingly, ChatGPT failed to process any direct media uploads with its pure text interface. Bing Chat also lacked file analysis abilities. But Perplexity AI and Claude AI both successfully interpreted the PDF content and provided summaries of the document.

Perplexity AI gave the edge here with robust tools for ingesting and summarizing general media. This opens diverse applications in research, reporting, and document comprehension automation.

Evaluating Math Problem Solving Abilities

While language and conversational abilities represent the primary strengths for these AI chatbots, evaluating ancillary skills in domains like mathematics further tests the limits of their reasoning capacities.

We provided all chatbots with the same complex word problem needing logical representations and calculations to solve. Disappointingly, ChatGPT, Bing Chat, Perplexity AI, Claude AI, Google Bard, and Heypi all failed to comprehend the relationships expressed in natural language or properly setup and calculate the mathematical logic required.

Without explicit programming tailored for mathematical reasoning, none could match the math word problem solving capabilities found in proprietary solutions like Mathematica or Maplesoft. User beware when expecting advanced analytic skills!

Long Text Summarization Capabilities

With increasing availability of long-form content across news, books, and online writing, summarization skills enable AI chatbots to distill key information down concisely. We tested summarization capacity using the text of Tim Ferriss' public blog.

Unable to directly access internet links, ChatGPT failed to interpret the content. Bing Chat, Perplexity AI, Claude AI, and Google Bard could all successfully summarize the lengthy blog text through public web access.

Interestingly, Claude AI achieved this despite not technically having internet connectivity. Instead, its large text input allowance enabled summarizing the full inserted article content directly. So all but ChatGPT demonstrate strong summarization capacities.

Comparing Availability of Leading Chatbots Globally

Considering availability by country enables assessment of the true reach of these AI chatbots across audiences worldwide. Most provide broad global access, but some remain limited by region.

Impressively, Both ChatGPT and Bing Chat are available in over 160 countries currently. Perplexity AI's country reach remains undocumented. Claude AI only launched in the US and UK, though VPN workarounds provide wider access.

Google Bard as announced its availability in over 180 countries. And Heypi has the smallest footprint focused solely on US access. So ChatGPT and Bing Chat lead for international chatbot reach right now.

Conclusion and Recommendations

Reviewing critical access, capabilities, and availability considerations across leading AI chatbot options enables an informed selection based on individual needs and priorities.

With free powerful tiers and global reach, both ChatGPT and Bing Chat lead the pack as smart productivity-enhancing tools for general users. Perplexity AI also warrants consideration as a paid enthusiast-level alternative.

For specialized applications, Claude AI dominates long-form text comprehension while Bing Chat wins for robust visual intelligence through image uploads. And easy free exploratory access makes Google Bard another attractive entry as well.

But no single solution provides top marks across all evaluation criteria. Prioritizing key differentiating factors allows matching specific use cases to the best chatbot available right now among these competitive options.
