ChatGPT Review

What is ChatGPT?

ChatGPT is an AI assistant made by OpenAI, an American company founded in 2015. It's the most widely used AI tool in the world - hundreds of millions of people use it every month. You can access it at chatgpt.com in any web browser, or through the app on your iPhone or Android phone.

ChatGPT works by conversation. You type - or speak - a question or request, and it responds. You can ask follow-up questions, ask it to explain something differently, or take the conversation in a new direction. Each conversation feels like a back-and-forth exchange rather than a one-off search.

Voice mode: speak instead of type

ChatGPT's voice mode is the best available in any AI tool we have tested. Here is how it works on the mobile app:

1. Open the ChatGPT app on your phone
2. Tap the headphone icon at the bottom of the screen
3. Speak naturally - ChatGPT listens
4. It responds, in a clear, natural-sounding voice
5. Keep talking back and forth as long as you like

The voice is not robotic. It sounds like a real person speaking. You can interrupt it, ask it to repeat itself, or change the subject mid-conversation. This makes it feel genuinely like talking to someone rather than operating a machine.

Voice mode is particularly useful for anyone who finds typing slow or difficult due to arthritis, visual difficulties, or simply a preference for speaking. You can ask questions, get answers, write emails (just describe what you want to say), and hold a proper conversation - all without touching the keyboard.

The mobile app

The ChatGPT iPhone and Android apps have been designed to work well on a phone screen. A few things worth knowing:

• Large text is supported. Your phone's accessibility text size settings apply to the ChatGPT app, so if you use large text elsewhere on your phone, it will appear large in ChatGPT too.
• The interface is clean. There is not a lot of clutter. The main screen is a text box where you type (or tap the microphone to speak), and the conversation appears above it.
• It works with screen readers. VoiceOver on iPhone and TalkBack on Android both work with the ChatGPT app.

The community: tutorials and help everywhere

Because ChatGPT is so widely used, there is an enormous amount of help available online. If you search on YouTube for "how to use ChatGPT" you will find hundreds of videos - many made specifically for people who are new to it. There are also written guides, forum posts, and Facebook groups dedicated to helping people get started.

This matters for practical reasons. If you get stuck or want to learn how to do something specific, you are very likely to find a clear explanation online. With newer or less well-known tools, that kind of community support doesn't exist yet.

What ChatGPT can help with

ChatGPT handles a wide range of everyday tasks:

• Answering questions - On any topic. History, health, how things work, what something means.
• Writing emails and letters - Describe what you want to say and ChatGPT drafts it. You can ask it to adjust the tone or length.
• Planning - Holiday itineraries, meal planning, packing lists, birthday party ideas.
• Creative projects - Writing a speech for a wedding, drafting a poem, thinking through a story.
• Understanding documents - Paste in a complicated letter and ask for a plain-language explanation.
• Hands-free conversations - Ask questions and get answers entirely by voice, without touching the screen.

Free tier vs. paid plan

The free tier of ChatGPT runs on GPT-5, which handles everyday questions and writing tasks well. For most people starting out, it is fine to begin for free and see how much you use it.

The Plus plan at $20 a month gives you GPT-5.5 - a noticeably more capable model - along with Sora video generation, Deep Research, and Agent Mode. Voice mode is available on both free and paid plans.

Starting with the free version makes sense. If you use it regularly and want the advanced features, the $20/month plan is worth considering.

Privacy

OpenAI's privacy policy allows it to use your conversations to improve its models, unless you opt out. You can turn this off in your ChatGPT settings under Data Controls - look for "Improve the model for everyone" and switch it off if you prefer.

ChatGPT does not sell your data to advertisers. The main use of your data is training - improving future versions of the model. As with all AI tools: don't type in passwords, financial details, or sensitive personal information.

OpenAI offers a business version (ChatGPT Team or Enterprise) with stronger privacy protections if that is relevant to you.

Limitations

• Free tier has limits. The free version lacks Sora, Deep Research, and Agent Mode. For the full experience, the $20/month Plus plan is worth it if you use ChatGPT regularly.
• Occasional errors. ChatGPT, like all AI tools, sometimes gets facts wrong. Always check important information, especially for health or financial matters.
• Privacy opt-out required. You have to actively switch off data use for model improvement - it's on by default.
• Can be verbose. ChatGPT sometimes gives longer answers than necessary. If you want a shorter reply, just ask: "Can you give me a shorter answer?"

Our verdict

ChatGPT is the right choice if voice is important to you. The voice mode is genuinely the best available - natural, responsive, and easy to use on a phone without any technical knowledge. It is also the best-supported AI tool in terms of online help - if you want to learn how to get the most out of it, the resources are there.

The free version is a reasonable starting point, and you can always upgrade to the Plus plan later if you find you're using it regularly. For document understanding and nuanced questions, Claude tends to give clearer answers - but for voice use, creative tasks, and hands-free convenience, ChatGPT is our top pick.
