Why is Torii not completely free?

Translating text in images involves several steps:

• Text detection - scan the image for text using OCR models
• Text extraction - convert pixels to text using OCR models
• Text translation - using GPT-4 or Google Translate (click for their API pricing page)
• Text inpaint - remove old text from image

All of these operations are costly because they involve AI models for each step and are computationally expensive and need to run on some server somewhere accepting requests. This extension cannot exist without paid support covering the costs of these operations.

Just because ChatGPT is free or because Google Translate is free doesn't mean using their APIs in Torii is free. Developers have to use APIs, which are not free. Click the links above to convince yourself.

How do credits work?

Credits are the units used when calculating the cost of translating an image.

Each newly requested image has a base cost of 0.3 credits, which cover the costs listed above.
Next, depending on the chosen translation model, additional costs will be added based on the number of tokens:

• GPT-4o (expensive, high quality) - 0.0006 credits per input token + 0.002 credits per output token
• GPT-4o-mini (cheap, medium quality) - 0.00005 credits per input token + 0.00015 credits per output token
• Google Translate (very expensive, low quality) - 0.004 credits per input character

Example: cost of translating an image with 100 characters from Japanese to English using each model

• GPT-4o - 0.3 + 0.0006 x 100 + 0.002 x 50 (output tokens) = 0.46 credits total
• GPT-4o-mini - 0.3 + 0.00005 x 100 + 0.00015 x 50 (output tokens) = 0.3125 credits total
• Google Translate - 0.3 + 0.004 x 100 = 0.7 credits total

Therefore, 100 credits will last you for 218|320|142 translations on average with GPT-4o|GPT-4o-mini|Google Translate. (assuming the average image has 100 characters)

GPT-4o-mini is the default model and is cheap, fast, and accurate. The full GPT-4 model is slower but higher quality and 10x more expensive. Google Translate is super fast, but lower quality and most expensive. I have added it mainly for people who only care about speed, but I do not recommend it.

This pricing model is more fair than a fixed pricing model (1 credit = 1 translation), because you pay for what you use. Some images have only 3 words in them, whereas others have super long walls of text.

How does the Monthly Subscription work?

When you choose a subscription, you get a certain amount of credits at your disposal every month while your subscription is active. Those credits can only be used during that month and they do not accumulate. Only the one-time credits stay forever until they are used up and only they can accumulate if you purchase them many times.

Both subscriptions and monthly credits can be purchased at the same time. You can only have one subscription but you can have many one-time purchases. Every month, you use up your subscription credits first, and then you start using up your one-time credits.

If you're on a monthly subscription, you can see your subscription credits and your one-time credits while hovering over the total numeber of credits you have in the extension popup or on your account profile on the website.

How does the FREE TRIAL work?

You get 5 free credits when creating your account. Use this free trial to see if Torii is right for you. If you decide to buy translation credits from the Pricing page, whatever amount you purchase stays with you forever until used up.

Why do I need to login with email or Google?

Login is necessary because Torii provides an expensive to run service that can be easily abused and spammed if not for having user accounts. Without accounts, anyone can access the translation API freely. Torii can't support potentially thousands of free requests every second.

Why can't I use a disposable email?

I understand that for privacy reasons some users might not want to use their personal email, but unfortunately, most of those disposable temporary emails are used for abusing the Free Trial by creating a large number of free accounts and using the 5 free credits over and over again. Please use a normal email - domains like google, yahoo, hotmail, etc. Uninstall Torii or remove website cookies, and try again. Check the above QnA for more reasoning.

Can I use Torii's API alone, without the extension?

Yes, Torii's API is available here on RapidAPI.

Do you have a Discord Server?

Yes! I just made one! Come say hi at Torii's Server.

Does translating the same image multiple times cost credits?

No, translations in Torii cost credits per unique image-language pair.
Meaning, if you choose to translate an image you have already requested in the past, in the same desired language as back then, you will not be charged any credits. If it's the same image, but now a different target language, it will cost the usual amount of credits.

Does the extension work on any website?

Yes, it works on any website. All the extension needs is an <img> HTML element and it will work when hovering over.

Why is the extension not working?

Some websites make it very difficult for images to be downloaded. They encrypt the images or shuffle them with some algorithm. Torii needs to be able to download the image in order to process it, because it can't simply grab the image off your browser page due to Chrome's security policies. If an error occurs then that is most likely the case and you are advised to download the image yourself and upload it locally in the Translate page. Another option is going to a different website where Torii works better. There are plenty alternative sites online, just google it.
