Transcy: AI Language Translate

I have been using Transcy for translation on my Shopify store for months, and the app itself worked decently for basic multilingual needs. However, in late January 2026, Transcy unilaterally changed my subscription plan WITHOUT my consent or any prior notification, upgrading me to a much higher tier and charging me nearly $200 extra per month.
This is a blatant violation of consumer trust and business ethics. I never approved the plan change, received no email alert, and only discovered the massive overcharge when checking my Shopify billing. Their support has been unresponsive when I requested a downgrade and refund for the unauthorized charges.
For any merchant considering Transcy: BEWARE. They will arbitrarily change your plan and overcharge you without permission. This is unacceptable for a paid app on the Shopify marketplace. I cannot recommend this app at all due to this predatory billing practice.

After two days of communication and assistance from Shopify staff, Transcy refunded me the extra $189.90. Although this wasn't all the extra money I'd spent since January 26th, I'm still grateful for their willingness to communicate amicably and try to resolve the issue.

Édit : finalement trop de problèmes j’ai dû arrêter d’utiliser l’app et la désinstaller malgré les heures passées dessus. Un bug gênant sur mon thème, les traductions que je rentrais manuellement était écrasé par une traduction automatique de mauvaise qualité

L'app n'est pas évidente à prendre en main. Si on veut utiliser l'IA, il faut l'offre à 60€ min. sinon c'est très cher pour traduire 1€ les 1000 mots ... J'ai rencontré quelques bugs au démarrage mais le support a été au top et à tout régler dans la journée. Une amélioration qui serait bienvenue serait de pouvoir mettre un contexte aux IA pour la traduction, ici on peut corriger quelques mots en automatiques grâce au glossaire mais ce n'est pas suffisant.

The app navigation is not the most intuitive, and manual translation almost always result in a coding error -- these two problems mean that I always have to contact their customer service, which is actually the strongest aspect of the app -- their chat is very active, and someone always responds in minutes. However, it would be neat if that wasn't necessary, and some of the bugs weren't there.

Didn't work correctly (only showed 2 currencies on the switcher, but I had selected all currencies)

Switcher is ugly imo as well.

Support war gut bis sehr gut, Qualität der KI Übersetzung allerdings mangelhaft. In unserem Fall ist viel nachzubearbeiten, sonst steht im Englischen schon nonsense da. Da wir nur englisch können, verzichten wir lieber auf weitere Sprachen die uns das System anbietet.

Ca. 5-10% der übersetzten Wörter und Begriffe sind falsch übersetzt. Da muss die KI noch ein paar Stunden (Wochen, Jahre?) auf die Schulbank, so geht's leider noch nicht.

UPDATE OF MY REVIEW *** The app is doing a great job. It is super easy to work with. My main reason for choosing Transcy are the unlimited words & pageviews! I had some technical issues in the beginnig, that sometimes seem to be bug-related – so I nearly switched to Weglot instead. But the support is outstanding and fast-replying, all problems were solved to my full satisfaction! This is one fact that Weglot can learn from Transcy, as their support is not very helpful and friendly. UPDATE: As Transy won't translate all notifications, this app is useless to me. Selling internationally while sending notifications in my default language German doesn't help. Now I'm changing to Langify …

I am not very satisfied with the App, because it can only translate 1000 products, in our shop there are more than 13000. It means that the remaining products are not translated for the seo and other functions.
On the other hand, the assistance is excellent.
Kind and competent staff.

First 2 weeks: 5 stars:
This is the best service I have ever received on an app. I was very shy with all the different translation apps, and in the end I choose this one because of the price and that you are not charged for the AI translation. I would suggest it is best to have your store base language in english, I unfortunately did not have. But the app easily allows you to manual change the languages on each page. Great app!

Update 4 months later:
Great customer service. But the app itself is lacking a lot. If you are using many theme templates, you are better off with another app. There is no clear way possible of easily managing the translations of your different theme templates. For shopify 2.0 this app is not recommended. The app is messing with internal links often. If you don't pay attention your site is probably unusable and showing a lot of 404 pages in the other language. The customer serivce is fast and good. I guess they have a hard job only working on solving problems.

They ask you to review straight after you set up the account and I've had to come back an edit my review again now. I am a premium user and the app itself is indeed really helpful for me and I will continue to use it but it does have some issues. The customer service is very nice. Super nice. But some of them really don't really know anything if you have a genuine problem. And being nice just becomes annoying after a while. They need to have a proper escalation system where if the customer is not getting a proper solution somebody considerably higher up fixes it. It took 3 days of multiple hours per day and multiple customer service people before I was given the most simplest of answers (so simple that i was annoyed at myself I didn't figure it out but even more annoyed that all these staff members couldn't tell me the answer, really poor. After that I was given somebody who knew what they were talking about but for my business, it had already cost me literally thousands of dollars with mistakes. And in addition, the app doesn't offer HREFLANG functionality, which given how much money they are making is quite annoying, it is the make or break for multi-lingual SEO and I would like to see them add it. I've updated my review a few times and will continue to do so as the app changes. For now I'm very happy with the customer service and the translations are now working very well on my site, but the costly mistakes early on cannot be overlooked and I don't think they are made apparent enough to onboarding customers and there is definitely ways to go for improvements for things like HREFLANGs so that multi-lingual SEO can be an option within the app... otherwise translating your store without HREFLANG can cause you more problems than you wish to have SEO-wise.

I uninstalled this app after using 10 months. So many issues occurred and made me so upset all the time. It was just the waste of time and money. But I would like to say thank you to Johnson. He was the only person who tried to understand the issue correctly and help me. But he was busy and not always available. Transcy should hire more advanced customer support like him. He did not hurt my feeling, while other did. But I also know it is not totally their fault. When their shift was over, the issue was transferred to the next available customer support who did not understand what really happened exactly. So I had to explain the issue to the new customer support. But she/he was gone also when her/his shift was over. And then another new support person asked me the same thing. I had to repeat and repeat the same things. Never ending. Transcy should not waste the customer's time like that. They also give the stress to their own support people with this system. If customer has the issue, somebody needs to be responsible until it is fixed. I hope they respect my opinion to improve their support system to make the customers & support team more comfortable.
