The reminiscence characteristic on ChatGPT was additionally useful, permitting me to set customized directions for the way I needed the bot to reply.

Choices to replace reminiscence and add customized directions on ChatGPT

In fact, there are some downsides. The free model can’t totally browse the Web, and I discovered the boundaries on utilizing superior fashions and picture era to be extraordinarily annoying. Generally, it hallucinates and stubbornly insists it’s proper even when it’s not–belief me, it’s a little bit infuriating! Plus, entry to newer options like SearchGPT and voice mode is locked behind the paid Plus plan.

That stated, ChatGPT stays a strong and dependable device for a wide range of duties, particularly contemplating it’s free. I imagine it has set a extremely excessive commonplace for any free AI chatbot available in the market.

The UI of Claude

Accessing Claude is straightforward, identical to ChatGPT. The free model primarily runs on the Claude Haiku mannequin. Sometimes, it offers restricted entry to superior fashions like Claude 3.5 Sonnet or Opus.

You may see from its response how Claude’s output is a lot better by way of writing type.

One other characteristic that I completely cherished was Claude Artifacts, that are content material or instruments you create with Claude that may be shared with the neighborhood.

Worse, you’ll be able to’t ship any messages if you hit the cap–you’re pressured to attend for a number of hours to regain entry, which is fairly annoying. Additionally, Claude can’t browse the net, so for any evaluation or enter on present occasions, you’ll want to repeat and paste the related textual content or content material into the chat.

Gemini’s interface

I completely cherished the truth that it could actually entry real-time information by way of Google Search. I’m additionally an enormous fan of the “Double-check with Google” characteristic. While you click on on it, the chatbot highlights sourced data in inexperienced and unsourced information in orange. With this, you’ll be able to actually know whether or not one thing is perhaps hallucinated or inaccurate.  This makes it probably the greatest AI chatbot for analysis. 

Truth-checking characteristic on Gemini

Free picture era with Imagen was one other side I favored. Whereas Gemini does point out utilization limits, I do not suppose I ever hit them or noticed an error message. 

Producing footage with Imagen 3 mannequin on Gemini

Gemini can write, create content material, code, and do the whole lot ChatGPT does. Nevertheless, a significant downside is the shortage of help for including recordsdata for conversations. I couldn’t add recordsdata, be it phrase or CSV, for evaluation as I may with ChatGPT or Claude, which felt restrictive.

Additionally, Gemini doesn’t supply a lot in the best way of customization for tone, type, or responses besides by way of prompts. I discovered this restrictive since I needed some management over how the bot responded to me. The free model runs on Gemini Flash 1.5, one of many quickest AI fashions accessible, however a paid plan is required to entry the superior Professional mannequin and options like file add.

General, it is a good ChatGPT different, albeit with some limitations.

I’ve to confess, getting began with Dialogflow wasn’t precisely intuitive. Google makes use of very particular phrases like intents (what the bot ought to do for particular queries) and entities (key particulars inside a question) to coach the AI bot, and understanding these ideas took me a while.

The UI of Dialogflow

As soon as I acquired the hold of it, although, I may see the potential. I may entry a variety of pre-built templates for AI brokers to get began shortly. I additionally favored that Dialogflow helps each voice and textual content interactions in a number of languages. This flexibility is a good characteristic, particularly for world companies.

Chatting with Copilot with out signing in

A standout characteristic for me was how Copilot shared its sources to the data on our chats. Each time it answered a query, it included hyperlinks to the sources it pulled the data from. This transparency is invaluable, particularly when you want to confirm the accuracy of the response or dive deeper into the small print. 

Copilot citing supply hyperlinks when sharing data

I additionally had enjoyable creating photos, and it appeared like one of many easy-to-use free AI picture turbines.  One other plus that many customers word is the combination with different Microsoft merchandise when you have Microsoft 365 subscription or Home windows. 

Creating photos with Microsoft Copilot

By default, Microsoft makes use of your information for coaching functions until you actively disable it. To their credit score, a disclaimer about this seems at first of each new chat, so that you’re conscious of how your information is perhaps used.

The most important draw back is the boundaries on conversations free of charge customers. I hardly had 4 conversations earlier than I acquired this message. 

Error message on Microsoft Copilot
