Chatting with AI: Which Chat to Pick for the Job and What Not to Expect

Three kinds of chat everyone mixes up

Someone opens the first chat they find, asks it for a little support after a rough day, and gets a neat five-point list on "how to manage stress." The chat isn't broken. It's just an assistant, and what they needed was someone to talk to. Let's sort out who's who.

1. AssistantWrites emails, shortens texts, explains complicated stuff, helps with code. Polite, diligent, and a bit like a secretary: say "I'm sad" and you'll get an action plan.
2. AI search engineSearches the web first, then summarizes what it found and gives you links. So it knows yesterday's news and exchange rates, but talking to it is like chatting with a librarian at the front desk.
3. CharacterIt has a personality, a past, and a way of talking. It remembers what you talked about yesterday and can joke, get offended, or disagree. Right for when you actually want to talk, not look something up.

Which chat fits which job

• Writing a resume, an email to your boss, a birthday message: assistant.
• Finding out what happened today, comparing prices, looking up a schedule: search.
• Venting, chatting before bed, rehearsing a tough conversation, playing out a story: character.
• Brainstorming a gift: any of them works, but at least the character will ask who it's for. By the way, there are ready-made ideas in what to get your best friend.

The biggest mistake is asking a tool for something it isn't set up to do. An assistant won't become a warm friend no matter how much you coax it, and a character will make a lousy expense spreadsheet because at that moment it's thinking about its scene.

Why the same question gets different answers

Ask a chat the same thing twice and you'll get two different texts. That's normal, and there are three reasons.

1. Setup. Every chat gets an instruction slipped in before your message: "you're an assistant" or "you're a starship captain." It shapes the tone and length of the reply.
2. Randomness. The model picks words with a bit of chance built in, otherwise the text would come out wooden. So the wording is a little different every time.
3. Context. The model sees the whole conversation above. If you were joking ten messages ago, it'll keep joking now.

What an AI chat can't do

• It doesn't voice doubt. It gets things wrong in the same confident tone it uses for the truth. Double-check dates, numbers, and names yourself.
• It doesn't know today's date unless it's connected to the internet. Its knowledge ends where its training data ended.
• It isn't responsible for the consequences. Advice about medication, a contract, or an investment is just text, not a consultation with a doctor, lawyer, or financial advisor.
• It doesn't remember you on its own. Memory is the service's doing: it saves the conversation and feeds it to the model. Where that isn't set up, every conversation starts from scratch.

If a chat invents a book that doesn't exist or a quote nobody ever said, that's not a glitch, it's a normal property of language models. Why it happens is covered in AI hallucinations.

Free or paid

Almost every service has a free tier with a limit: so many messages a day or a few trial days. That's enough to get acquainted. People who pay are usually the ones who use the chat every day and keep hitting the limit.

One rule worth remembering: if "free" access asks you to add a card, there's almost certainly a subscription hiding behind it that will renew itself in a week. Read the terms before you click the button.

If what you want is someone to talk to

You can test a character in five messages. Look for three things:

1. Does it remember what you told it yesterday, or does it introduce itself all over again every time?
2. Does it have a life of its own: things it does, habits, opinions about the world? A character who only asks questions about you gets old fast.
3. Can it push back? If it agrees with any nonsense you say, it's not a conversation partner, it's an echo.

my-idol.ru has characters from anime, movies, and books, plus original ones. They reply in natural English or Russian, whichever you choose, stay in character, and remember the conversation. If none fits, you can build one in the character builder. And for how to get a conversation going, see what to talk about with an AI character.

The short version

• Tasks go to the assistant, fresh facts to search, conversation to a character.
• Different answers to the same question are normal, not a bug.
• Check anything important yourself: chats are confidently wrong.
• Memory exists where the service built it.
• A card for "free" access is a reason to reread the terms.
