The short answer

SeaArt and Tensor.Art are services where you pick a model in the browser, write a prompt and make an image. What is free, the terms for each model and whether commercial use is allowed can change, so check the official guide. When using them for all-ages work, check the age-related settings and the range of public sharing.

What kind of services are SeaArt and Tensor.Art?

They are services for Stable Diffusion-style image generation that work in the browser alone, and a feature of them is that you choose models and LoRAs to make pictures.

To run image generation on your own computer you have to set up an environment. With services like SeaArt and Tensor.Art you log in from the browser, choose models and LoRAs that other people have published, and make images just by writing a prompt. However, what is free, how crowded it is and the terms of each model change with the service and the time. Check the official guide before you use them.

What to check	Where to look	Note
What you can do for free	The pricing and credit information	The amount or number you get each day can change
Terms of a model	The description on the model page	Whether commercial use and redistribution are allowed differs by model
Age-related settings	Account and display settings	For all-ages use, check the range of what is displayed
Whether your pictures are public	Posting settings	Check that you can choose public or private
Commercial use	The terms of service	Conditions may change with your plan

What are the steps for making your first picture?

Steps for making an image in the browser

Create an account on the official site and check the terms of service
Open the image generation screen
Choose a model that fits the picture you want, such as one for anime pictures
Write a short prompt (1girl, solo, smile, school uniform and so on)
Decide the size and the number of images and make one image first
Fix the parts you do not like one at a time and make it again

1girl, solo, long hair, red ribbon, school uniform, smile, looking at viewer, classroom, window, sunlight, upper body

scenery, no humans, lake, mountains, morning mist, soft light, wide shot

Rinka's tips

At first, settle on one model and make several pictures with it. You will see how the prompt works
Try copying the "recommended prompt" or "trigger word" written in the model description first
Try a small size first so you do not use up the free range

How do you choose models and LoRAs?

Do not choose by popularity alone. Look at the sample pictures, the terms of use, and the supported type (such as SDXL).

See whether the sample pictures are close to the art style you want to make
Check whether the model description states the terms for commercial use and redistribution
Choose a LoRA of the same type as the model (SDXL or SD1.5, for example)
When making all-ages pictures, choose ones whose art style and description are for all ages
Try several and keep a record of the models that suit you

What if it does not work well? (Common failures and fixes)

The main causes are forgetting a model's trigger word, a mismatch between the type of LoRA and model, and using up the free range.

Failure	Cause	Fix
The picture is not in the art style you wanted	The model does not fit the style	Switch to a model whose sample pictures are close
The LoRA has no effect	The type of the model and the LoRA differ	Choose a LoRA of the same type
The waiting time is long	It is a crowded time of day	Shift the time, or try a small size
You used up the free amount	The number of images or size is large	Check the free range in the official guide and decide a number to try
Unintended pictures appear	The prompt is long	Shorten it and add things one at a time

What should you check to use them safely?

First check three things: your account settings, the range in which your pictures are public, and the terms of use of the model.

Do not use personal information or face photos as source images for generation
When you publish, say clearly that the picture was made with AI
Do not use pictures made to resemble other people's work or characters for publishing or selling
Follow the terms written in the model description (commercial use, redistribution, credit)
