Sintra AI 

Very frustrating with the credits scheme. I pay a yearly subscription. get 250 token per month and burn through them in 3 days.

This is typically with using the app for 3-4hours each day. And this is set to the lowest credit usage they allow. Just so poor and have transfered to Google Ai Studio. Pity as it's good when you can actually use it!

I'm a small business with one employee, myself. I just can't understand why the credits as so limited. Very frustrating.

I have asked four times to be contacted by phone. They do not provide a customer service phone number which will not allow me to explain that someone impersonated me and signed up for their service without my knowledge or consent. This company has horrible customer service.

I bought Sintra because it’s marketed as an “all‑in‑one” app — but in my experience that’s not true.

The biggest issue is the image generator: it cannot reliably produce correct English text. Any time I tried to create poster-style graphics with wording on them, the text came out wrong (misspellings/garbled letters). When I raised this, I was told the workaround is to generate the poster without text, then leave Sintra and use another app like Canva or Photoshop to add the text correctly.

That defeats the entire reason I paid for Sintra. If I still need other software to finish basic marketing assets properly, then it isn’t “one app” — and the advertising feels misleading.

On top of that, the helpers repeatedly produced AI-generated images for my TV installation content that looked fake, even after I’d told them many times not to use artificial images for installs. It’s exhausting having to correct the same thing over and over.

Overall, the software has been a terrible experience for me, and I want other customers to know these limitations before they waste their money.

I was just about to sign up to Sintra based on an ad I've seen on Facebook, but after reading the millions of 1-star reviews, there's no way! It appears to be nothing more than an organized fraud corporation!

i had a appointment for a demo.. i'm still waiting.... no one showed up..

I emailed for help and received a reply from your AI. You make it very hard to request a refund. Here is a copy of what I said in my email. I started using Sintra on October 3, 2027, and was surprised to learn that you require monthly credits to access this AI. The cost of buying these credits is very expensive, and nowhere on the sign-up pages does it state that there are limits to what you can do.
I also noticed that they pay individuals to give them a 4- or 5-star rating to keep their star rating high.
I canceled my subscription and am requesting a full refund.
Please note that upgrading a subscription means purchasing additional credit on the existing Sintra X subscription. We have refunded your Sintra X subscription. Your refund will reach you within 5-10 business days, and your subscription is canceled. Increasing your monthly credit allowance is considered a credit top-up. As we do not offer one-time credit purchases, the way to obtain additional credits is by upgrading your subscription, for example, to Sintra 300, which provides a recurring credit top-up to increase your monthly credits.
I have filed a complaint with the FTC about this company. I recommend that anyone else who's had problems with them file complaints with the FTC to, in my opinion, help stop this fraudulent company.

It is an unethical company , they over charge you and its almost impossible to cancel the subscription. THey take all your data

I paid $200 USD for a lifetime membership to Sintra. They have now rebranded to "Sintra X" and are demanding a monthly subscription to use the platform I already paid for. Support refuses to honor the original terms of sale. Do not buy this. They will take your money for a "lifetime" deal and then lock your account a year later. I have my original receipt and proof of purchase.

Title:
WARNING: Trustpilot is displaying a notice that Sintra has been offering incentives for reviews. That is a serious credibility problem. I would not take the glowing reviews at face value—especially when my own experience was this bad.

Sintra sold me the promise of AI helpers that would take work off my hands. Instead, I got an app I had to babysit.

Connecting my social media became a frustrating loop that repeatedly locked me out. The helpers sat unassigned or did nothing. I kept checking, correcting, and telling them what to do. If I have to supervise every step, it isn’t helping me—it’s creating another job.

I paid for less work and got more stress. The subscription kept charging while I struggled to get the product to do what it was supposed to do. That felt like a subscription trap.

I regret buying it. Think twice before you pay. In my experience, Sintra AI did not deliver the help its sales pitch promised.

Worst AI i have ever used. Agents are not trained and provide basic functionality. The credits included would run out in a day and you have to pay more for poor service. They trap you into a contract so you can't stop paying. BAD product, run away.

Don’t use this app. Impossible to cancel. It’s a reoccurring charge that is not authorized. Beware

I bearally purchased the one year pack and starting to do the set-up for my business, I was basically just fedeling around and they already blocked me and starting to ask and charge me for more credit 😅, after spending money for the a year subscription. Anyway they don't handle all the work for your probably have to demand a big chunk of your time settling it up.

I've tried other promotional websites before on three occasions in the last 3 years. I didn't even get 1% return which would be one or two visits to my website pages. I canceled them immediately because I was seeing no results I felt I had wasted my money. I was promoting through the wrong promotion app.

Tonight, I was scrolling through my phone. I landed on this ad for Sintra. I'd seen it for a couple of years and it stayed in the back of my mind. So tonight, because I had a little bit of extra money right now, I decided to try it see how it works. I have to tell you the immediacy and the clarity and the quick response, and the answers and the change suggestions was unlike any other platform I've tried. I felt like I truly had a team around me and I felt like I was talking to them in person rather than to an AI. They even explain to me why my sites were not getting very many hits based on the way the metadata is inside of it. I enjoyed the conversation with my TEAM (😀 I have a Team). I enjoyed that they knew what I was talking about; gave me smart and investigated information about my situation; clear reasoned advice and even pre-written emails to send to the appropriate departments to ask for corrections to my issues at Amazon KDP. I'm looking forward to the meeting that we set for Tuesday. Now, I have to go do the assigned tasks, for my part in making this work for me. I have a good feeling in my heart, and stomach that this was the right decision. I really appreciate how well it worked for me, Just, in one evening I have more information about what's going on then I've had for 3 years. I have more information about what I need to do to fix things, making my promotion more successful than I've had at any time. So I have to tell you I appreciate it. I feel like I'm not going to drown in all this. If all goes well, I will finally reach my goal of making a passive income, after several years of hard work creating two book series. Thank you very much. Here's crossing my fingers that this will benefit my goals. Sincerely, Frances.

I was one of the first users when it went live and absolutely loved it. I told everyone how great it was for my small business. THEN the sneaky credit switch happened which really annoyed me and also the features changed. As a business owner you run out of credits within a day! Its a cool tool but there are other, cheaper alternatives out there that won't quietly change the subscription plan on you!

Company promises simple marketing assistance. However, the platform can't generate social media content using the media you provide. The plan provides you with 250 credits, which is insufficient to even finish setting up the platform to work for your business. There is not way to purchase additional credits without signing up for a much more expensive plan. Their 14-day money-back guarantee is false. They will argue and cite a policy that they can not refund any attempts to get enough credits to get their insufficient platform to work. Expensive, lacks functionality, has bad customer service.

It’s ok. It has a smooth UI and seems to work well for what it does. I just wish it was more upfront about what it can’t do. It’s unfortunately pretty useless to me.

They do not explain their "credits" system well enough, and suddenly the credits for the month are gone without warning, so you have to purchase more. I entered into an annual contract as I thought that it would be well enough for my purposes of social media and a bit of email drafts. And now I am stuck with a system I cannot use due to missing "credits", and I missed the 14 day cancellation window due to being hospitalised and having a baby. Absolutely appalling, deceitful and unprofessional. No compassion for extreme situations, just robotic "Our T&Cs state that"...

Im still technically using the tool for now on VERY specific tasks, but everything you are reading is true. Their latest update pretty much made the platform significantly worse. The credit usage is through the roof. I believe this is because of the Brain Ai. The more you feed it and the more it has to sift through the data the more credits it uses. THAT SAID, I personally feel like it is using far too many credits. I was in the middle of a writing an article that had for sure a good amount of data applied to it, but it was only a writing project. No images, graphs, or video. This thing was burning through 13-15 credits A PROMPT. Sometimes only submitting to me a single paragraph. And if you only have 250 credits then you do the math. I didn't catch this in time so I had to upgrade twice costing me almost $200 EACH time. At that price point you can just subscribe to a bunch of other Ai platforms that do specific tasks better and you will get far more out of them treating them the same as you would the helpers in Sintra.

This platform started off promising but it definitely feels a bit like a bait and switch. Maybe it isn't but the value sure doesn't really feel like its there anymore and there are plenty of competitors ready to take your hard earned money. That said I like the style of this platform so I hope Sintra pulls it together.

Doesnt work since the last update. Reached out to support twice and got no response back.

My favorite part of the latest update is after you use your 250 credits for the month you can no longer do anything...at all. Can't even buy more credits to keep prompting unless you completely upgrade your subscription.

Plus i tried setting up 30 different posts and even after they were scheduled NONE OF THEM POSTED. I guess because i was out of credits??? Meaning you get double charged every time you try to do this 🤣 what a joke. No thanks, cancelled my subscription.

I'm pretty dissapointed overall. Wish i had two more thumbs cause I'd give this platform 4 thumbs down

In the early days I took a gamble due to bad review but it was great.

Over the years I think it has advanced too much that it has slowed it down and confuses itself.

Each weekend I would sit for an hour-ish and post for the week 5 times a day. That now takes a whole day. Sintra gets things wrong all the time confusing itself. I am doing the same thing I have always done giving it pretty much the info to queue to post for me for the week ahead.

Not only does it get things wrong, it then changes things that are right as it can't figure out which one it should be doing. On top of that, it is now extremely slow so I will often do two things at once when doing Sintra not to waste my time.

I am currently looking for something else as they also have now moved to a credit system - when my account moves over to that, I will leave as it will use credits getting it wrong -so it will be a costly product.
