AI tools have been making waves. First, it was AI image generators, then came ChatGPT with the ability to generate human-like text conversations. The potential for this technology is incredible, and you can use it right now.
What Is ChatGPT?
ChatGPT was created by OpenAI, the same company that also made DALL-E 2, which kicked off the wave of AI image generators. While DALL-E 2 generates images, ChatGPT is solely text-based—and it’s not OpenAI’s first chatbot.
OpenAI’s original GPT (Generative Pre-trained Transformer) chatbot was trained on a massive collection of text data from the internet, allowing it to generate human-like text in response to a prompt. It was followed with GPT-2 in 2019, GPT-3 in 2020, and ChatGPT on November 30, 2022.
ChatGPT works by using algorithms to analyze and generate text based on the prompt from the user. When a user inputs a prompt or question, ChatGPT uses its training data to generate a response that is similar to what a human might say in that context.
Essentially, ChatGPT is an advanced chatbot that uses the massive repository of text on the internet to attempt to converse like a human would. While it certainly comes across as knowledgeable, it’s far from perfect.
Is ChatGPT Free?
ChatGPT is free to use for anyone with an account on OpenAI’s website. You can create a free account with your email address, Google account, or Microsoft account. At the time of writing in February 2023, there are no usage limits on the free version of ChatGPT.
There is also a “ChatGPT Plus” subscription plan for $20 per month. It offers reliable availability when demand is high, faster response speeds, and priority access to new features.
How to Use ChatGPT
First, navigate to chat.openai.com in a web browser on your computer, smartphone, or tablet. You’ll be asked to “Log In” or “Sign Up.” You can sign up with an email address, Google account, or Microsoft account for free.
After you’re logged in, you can begin using ChatGPT. Use the text box at the bottom of the screen to type a prompt. This can be a question or a specific request. Press the paper airplane icon to submit.
ChatGPT will “type” out the response in real time. When it’s done, you can provide feedback with the thumbs up and down buttons.
Each prompt kicks off a conversation. You can enter follow-up prompts or change the subject entirely. It will remember what you’re talking about.
If you don’t think the response was good enough, you can simply ask it to try again.
You can also tell ChatGPT when it’s incorrect about something. (I made it say something false about Tom Hanks.)
You can bookmark the chat.openai.com website to quickly come back to it in the future.
How to Fix “At Capacity,” “Network Error,” and Other Problems
ChatGPT is extremely popular, and it’s still just a research project. You may not always be able to use ChatGPT if a lot of other people are also using the service at the moment. You will see a message saying “ChatGPT is at capacity right now” if you can’t use it. To fix this error, you may want to come back later—or you could perhaps just refresh the page in your web browser and it may work.
If this is an issue for you, paying $20 per month for ChatGPT Plus will get you priority access so you can use ChatGPT even when it’s under a heavy load.
You may also see errors in your conversations while using ChatGPT, like a “network error” message. This can sometimes be caused by a problem with your network (for example, an internet connection problem, Wi-Fi issue, or a VPN problem), but it may also be a problem with ChatGPT’s servers. In some cases, requesting a very long response from ChatGPT may result in an error. You may be prompted to request another response from ChatGPT or try reloading the page.
If other web pages are working properly but you’re experiencing errors with ChatGPT, it may be an issue with lots of people trying to use it—step away from ChatGPT and try it again later, or consider paying for ChatGPT plus for priority access.
How to Save a ChatGPT Conversation
Thankfully, ChatGPT conversations are automatically saved to your OpenAI account. You can access past conversations from the sidebar menu. Every time you start a new conversation, it’s added to the list.
On desktop, the sidebar is already expanded. Click a conversation to read it again or continue chatting. Conversations are named based on the first prompt you entered.
In a mobile browser, you’ll need to tap the hamburger menu in the top left to expand the sidebar.
The sidebar menu is also where you can clear your conversation list. Simply select “Clear Conversations” toward the bottom of the menu.
That’s all there is to it. Your ChatGPT conversations are saved to your OpenAI account, so wherever you can log in, you’ll be able to see them.
Frequently Asked Questions
What Does “GPT” Stand for in ChatGPT?
“GPT” stands for “Generative Pre-trained Transformer.” A GPT is a language model that uses deep learning to generate human-like text in response to a prompt. The “Chat” part of the name comes from being a chatbot.
Is ChatGPT Plus Worth It?
ChatGPT Plus is a subscription plan for $20 per month. It includes reliable availability when demand is high, faster response speeds, and priority access to new features. Power users may benefit from the Plus features.
Does ChatGPT Save Data?
OpenAI says it does not save data from individual interactions with ChatGPT. When you have conversations with ChatGPT, your input is processed to generate a response, and the input data is not stored by OpenAI after the interaction is complete.
Does ChatGPT Have a Smartphone App?
OpenAI does not have an official ChatGPT app for iPhone and Android. It does, however, work well in a mobile browser on a smartphone. Due to its popularity, there are many fake ChatGPT apps in the Apple App Store and Google Play Store.
Does ChatGPT Deliver Accurate and Honest Answers?
ChatGPT can only be as accurate and honest as the material it analyzes. The accuracy of its responses is similar to how accurate you would be after reading an article online. ChatGPT can only tell you what it has read. It cannot tell you if it is accurate in the same way an expert with decades of experience could. It’s the difference between “I read a bunch of articles about plumbing” and “I’m a master plumber, and I can answer that question with authority.”
Does ChatGPT Use Real-Time Data and Current Events?
ChatGPT is not up to date on current events. At the time of writing, the dataset of the current version of ChatGPT only goes up to 2021. ChatGPT is not currently connected to the internet and does not “absorb” new information in real time.
Can I Use ChatGPT to Do My Homework?
There’s nothing stopping you from plugging questions from your homework into ChatGPT. However, you probably don’t want to do that. ChatGPT is often wrong because it was trained on text from the internet. It’s very good at sounding authoritative about something, but it could be completely wrong. You would need to do a lot of fact-checking to ensure accuracy. Not to mention it is most certainly a direct violation of your school or university’s academic integrity policies.

Pdf2gerb: Perl Script Converts PDF Files to Gerber format
pdf2gerb
Perl script converts PDF files to Gerber format
Pdf2Gerb generates Gerber 274X photoplotting and Excellon drill files from PDFs of a PCB. Up to three PDFs are used: the top copper layer, the bottom copper layer (for 2-sided PCBs), and an optional silk screen layer. The PDFs can be created directly from any PDF drawing software, or a PDF print driver can be used to capture the Print output if the drawing software does not directly support output to PDF.
The general workflow is as follows:
- Design the PCB using your favorite CAD or drawing software.
- Print the top and bottom copper and top silk screen layers to a PDF file.
- Run Pdf2Gerb on the PDFs to create Gerber and Excellon files.
- Use a Gerber viewer to double-check the output against the original PCB design.
- Make adjustments as needed.
- Submit the files to a PCB manufacturer.
Please note that Pdf2Gerb does NOT perform DRC (Design Rule Checks), as these will vary according to individual PCB manufacturer conventions and capabilities. Also note that Pdf2Gerb is not perfect, so the output files must always be checked before submitting them. As of version 1.6, Pdf2Gerb supports most PCB elements, such as round and square pads, round holes, traces, SMD pads, ground planes, no-fill areas, and panelization. However, because it interprets the graphical output of a Print function, there are limitations in what it can recognize (or there may be bugs).
See docs/Pdf2Gerb.pdf for install/setup, config, usage, and other info.

How This AI-Enabled Chatbot Radically Transformed Cancer Care Amid Pandemic
The critical industry that has been massively impacted by the pandemic is the healthcare sector; however, AI’s involvement has helped the industry weather the pandemic storm. The AI applications by companies bring back patients’ lives from the edge and improve diagnostics and treatment and help healthcare providers make informed decisions quickly. One such application has been developed by Hospido, India’s first holistic cancer care platform with which cancer patients can get the right treatment advice from India’s best cancer doctors, without visiting hospitals amid pandemic.
The pandemic lockdown has forced many people, including cancer patients, to avoid hospitals and discontinue their treatment due to coronavirus risk. And this is what triggered Karan Chopra, the founder of Hospido to bring out quality healthcare to these cancer patients through telemedicine and satellite treatments centres for providing the right treatment at the right time. In this article, Analytics India Magazine, got in touch with him to understand how this startup revolutionised cancer carer amid pandemic.

AI Chatbots for Business: Why You Need One Now!
It’s said that Artificial Intelligence will be just as smart as humans by 2050. Experts like Ray Kurzweil have even predicted that we’ll achieve a technological singularity by 2045.
From that point on, it’s believed that AI will start inventing Nobel Prize-winning inventions every 5 minutes. Granted it’s gonna be out of our control, but hey, at least we’ll see a revolutionary breakthrough.
We may think that these claims are outlandish and ridiculous, but if someone were to tell me in the 70s that there will be self-driving cars in the future, I would’ve wanted to smoke whatever they were smoking.
But guess what, here we are in 2020, and Tesla already has their self-driving cars on the roads right now. And these were all recently developed technologies. Did you know that the first chatbot was actually launched in 1966?
