First we have OpenAI's ChatGPT,
now we have Google's Gemini,
Microsoft's Copilot,
Anthropic's Claude.
They are as easy as typing a question in a box and let them work wonders. I've tested all of them and they do prove to be very useful and are good for cross-referencing results as well since they run on independent LLM.
Thus far, only Copilot does image creation, of all 4 listed above.
The potential of these are great. I've used them to convert a messy list of items into well organized spreadsheet for my manager. Used it to create instructions and write essays and such.
