You've probably already used ChatGPT, Gemini or Claude. They're excellent tools. But they all share one thing: every conversation starts from scratch.
The memory problem
When you open ChatGPT and ask "Where's my project at?", it has no idea what you're talking about. That's normal — it doesn't know you. You have to re-explain everything every time: your context, your preferences, your constraints.
It's like having a new intern every morning. Capable, but knows nothing about you.
The personal assistant: a different approach
A personal AI assistant like Zelly works differently:
- It remembers your conversations — what you told it on Monday, it still knows on Friday
- It learns your preferences — your favourite tone for emails, your food allergies, your goals
- It's always within reach — not in a browser tab, but right inside Telegram, on your phone
- It's private — your data isn't used to train a model
What does it actually change?
Take a simple example. You ask ChatGPT: "Suggest a meal for tonight."
It'll give you something generic. Maybe a recipe with shrimp when you're allergic. Maybe a dish for two when there are four of you.
With a personal assistant, the same question gives a different answer. It knows there are four of you, that your daughter doesn't like mushrooms, and that you're trying to cook more vegetables this week. The meal it suggests takes all of that into account.
Which one should you choose?
It's not either/or. Both have their place:
ChatGPT / Gemini / Claude are perfect for:
- One-off questions with no context
- In-depth research
- Code or technical tasks
A personal assistant is ideal for:
- Your day-to-day organisation
- Communication (emails, messages)
- Reminders and keeping track of your projects
- Anything that requires knowing you
The price of convenience
A ChatGPT Plus subscription costs around 20 CHF a month. A Zelly assistant starts at 24 CHF a month — for a service that knows you, lives in your pocket, and never asks you to explain it all over again.
For many people, that's a better investment than the generic tool they use once a week.
