I started using Tunera mainly because of the images, and then I tried the other features. Now I most often use it to create texts for posts, images, and sometimes videos.
What I like is that I don't have to keep several different services open. If I need to prepare something for publication, I can first create the text, then immediately the image, and later, if necessary, a video or music.
The work itself is quite simple. You just write in plain words what you want to get, and then you see the result. If something doesn't suit you, you just clarify the details. Over time, you understand how to formulate requests better.
Of course, not everything turns out perfectly on the first try. This is especially true for videos. Sometimes the movement or some details don't look as I wanted. Then I have to slightly change the description and run it again.
A plus for me is that I can use it through Telegram. I often do things directly from my phone, so it's really convenient.
Overall, Tunera has worked well for me. I use it regularly for work-related content tasks. I wouldn't say the service does everything for you, but it greatly simplifies the process when you need to quickly get a decent foundation and then refine it.
