What people say
poor "refund" policy
very expensive for what it is, couldnt compolete most the tasks or "ideas" it presented to me.screwed up my goggle calender and then couldnt recognise its own workings, or even find emails that it had previously told me about. offered me a refund and then told me that a refund would breach their refund policy-why offer it then?????
They monitor your usage!!!
They monitor your usage for each section. If you use up your allotted credits for the month you have to buy more. They don't roll over to the next month if you don't use them all.
BUYER BEWARE
BUYER BEWARE. I absolutely do not recommend the Sintra AI platform. I purchased Sintra for my nonprofit organization after discussing the platform and its credit system with a representative named Marijus. I was told that the credits should not run out quickly with normal or reasonable use. However, after using the platform for only three days, my available credits were gone. That immediately showed me that Sintra was not going to work for our organization. We are a nonprofit with limited funding, and we can only invest in services that provide meaningful assistance at a reasonable and predictable cost. A platform that exhausted its credits after only three days was far too costly for us to continue using. I attempted to cancel within Sintra’s stated 14-day money-back guarantee period. I contacted the company through its live-chat system and was assured that my services had been canceled. I later learned that the subscription had apparently only been scheduled to cancel at the end of the annual billing period rather than being properly canceled with a refund. Sintra has made the cancellation and refund process unnecessarily difficult. The company now claims it cannot locate my original live-chat request and will not refund my money unless I provide a screenshot. I did not take a screenshot because I reasonably believed Sintra’s own live-chat system would retain the conversation and that I could trust its representative when I was told the cancellation had been handled. During a later meeting, Marijus told me that a cancellation had been placed on my account but had been processed incorrectly. He instructed me to contact Customer Support to have it corrected. Sintra is now disputing my account of that conversation as well. I have repeatedly asked Sintra to review its own live-chat records and the recording, transcript, or notes from my meeting with Marijus. Despite the fact that I began attempting to cancel within the company’s stated time frame, Sintra has refused to issue my refund. It is obvious that this platform is not financially practical for our nonprofit, yet Sintra has made it extremely hard to cancel and continues to withhold the refund I requested within the guarantee period. The entire experience has been frustrating, time-consuming, and unacceptable. BUYER BEWARE: Carefully examine how Sintra’s credit system works before paying for a subscription. If you decide to try it, take screenshots of every conversation, record every cancellation request, and demand written confirmation. Based on my experience with its rapidly depleted credits, difficult cancellation process, and refusal to honor my refund request, I absolutely do not recommend Sintra AI.
Sintra used to be great but now…
Sintra used to be great but now they are one of the worst. They switched to credit based so you run out of credits in like one heavy day of use. It's ridiculous. I used to use it all month every day for hours. Now i get a few hours and I'm out of credits. They even charge credits for just talking to the AI, not even asking it to do anything. It's terrible, stay away!!!
Very dissappointed
Very dissappointed. Paid for a year but the AI isnt any good. Facebook ads images were absolutley shocking. A lot of the facebook ads werent suitable. Found a lot of the things were worse than just googling and using the built in ai. Ive deleted it and gone back to chat gpt. So Ive wasted a years subscription.
Really awful experience with them and 250 credits a month is a scam
I think it is really telling that they have breached the guidelines because they have been offering incentives for good reviews..... LOL. Here's my review: Really awful experience with the product, the customer service was even worse. I've been a customer since 2025 and it was such a breath of fresh air using the AI agent employees - the responses were great, so was the tone and I found myself supported as a solo business owner. Then all these changes... the credit system is an absolute scam. 250 credits will get you through one day for someone running a business. Not to mention the quality of their responses have deteriorated. I renewed my subscription in June this year, having not used it for a while and was appalled by it. Then an error occurred, somehow an additional workspace was created on my account and then I was only given 20 credits. Flagged to customer service and a human agent Patricija very intentionally made it difficult. When asked why that happened, said their system could malfunction sometimes and she could help me delete the additional workspace but "first and last time for me" warning. What a joke. Then required me to verify the credit card (last 4 digits) and she made a mistake because I gave her the right credit card used to pay and she insisted it was wrong. I showed her the receipt and on the receipt had the last 4 digits that matched what I gave her, and she still said no. I did not relent and asked her again to check, then without anymore messages just triggered the deletion of the additional workspace (that their system malfunctionally created). I unfortunately have to tolerate using them till June 2027 but hope you won't by giving you a warning.
Used to be good, not anymore!!
Used to be good. Not anymore! Very disappointed with Sintra since their updated version and their new credit system. Website scrapes do not work, freezes, chews credits from their system errors. Unfortunately I cannot recommend Sintra any longer.
This platform is hopeless with terrible Customer Support
This platform is glitchy, with constant outages, the Assistants do not effectively speak to each other, and behave erratically with the information they produce. They hallucinate constantly. The developers invited users onboard in 2024, initially as part of the growth journey but things kept getting worse in 2025 instead of better and now, in 2026 Sintra management refuse to give pro-rata rebates in return for a shoddy product and broken promises. They constantly requested me to share my usage story with Sintra, but what I did instead was submit constant reports on what was not working, but no resolution was recieved, however they didn't hesitate to constantly ask for Reviews... like I should be grateful their product did not preform. When I contacted them (after at least 6-months of not using their product) I was told they only refund after 14-days of a subscription being paid... how is that long enough to assess a product's effectiveness, when the developer continually assures you things will get better soon. When I lodged a formal complaint their attitude was 'tough luck'. When I gave feedback that their behavior around the pro-rata request was not ethical, their attitude was tough luck. And when I stated I was going to share my experience online they said... and I quote... "go ahead". Sound like a business that gives a F*^@k? No. EVERYONE stay a away from Sintra... your money is much better spent... and at a considerable saving... with Anthropic's Claude AI. Or if you want a Suite of Assistant, check out Marbelism... a colleague tells me it is far superior... and they offer great customer service. Shame Sintra, Shame.
proper thieves
proper thieves. They pretend to care until your cash back is gone then they start properly betting you with credit gone within a few chats. But now you're stuck on a full year subscription. Not suited for difficult tasks.
Run fast
Run fast. This company will not be here long. Worst customer service and in my honest opinion a scam. I will be filing a complaint with my credit card company about this app. Worthless and zero customer service
Scam
Scam, works bad, eat credits for nothing, changed terms during subscription what makes app almost useless for me
New Credit System is going to be their downfall
Used it for one day to learn how it works. It charged me 170 credits. I subscribed to 250 each month for one year and they won't refund you. They do not allow you to top up credits or add credits to allow you to learn how to use it. If you want more credits you have to upgrade your plan and will get the additional credits each month. They are like lawyers. They charge for every little thing you do. If you give them a prompt and they get it wrong and then you have to give them another and they say "sorry about that" You are charged credits for them to answer you that they made a mistake!!.....I used it for two days now have to wait an entire month to get my 250 credits back. Customer service said they understand the frustration. Don't waist your time and money. Go with an unlimited platform.
1 star only because i have to tick a…
1 star only because i have to tick a star, im just about to cancel after 11months with sintra, after today logging in to find im out of credits on an unlimited subscription account i was shocked, i messaged customer services and was told they can change the accounts and showed me the terms and conditions! this has never worked correctly since ive used it i had patience because i was paying for unlimited access but to now have to pay for credits that it will eat and get at lkeast 50% wrong or bad quality im not prepared to do that, chat gpt does a much better job on a free version, beware this eats into your time trying to get it to work and its been like it since early 2025 when i sub to it and its got worse, find something else id say they are only interested in making more money out of us with a poor service.
There customer service is horrible
There customer service is horrible, I was with then since Oct 2024. They have really gone down hill in a big way, I used to recommend them to everyone I knew looking for help with there business. NOT anymore, now I will tell them to avoid Sintra AI at every turn. No longer worth the headache.
Since the upgrade
Since the upgrade - I pay nearly £200 and get limited on credits, I now have to wait 3 weeks to be able to use it again. DO NOT RECCOMEND!
Credit system makes this unusable
I originally signed up to Sintra because the product looked genuinely useful and promising for my small business. I liked the concept and signed up for a year of Sintra X under the promise of unlimited chats for all helpers. However, the recent increase in base pricing for Sintra X (which I was moved to after upgrading my credits then downgrading them again almost instantaneously) and the introduction of credits more generally has made the service unusable for my needs. What was previously a straightforward subscription now feels heavily restricted and complex. The credit system means I’m constantly out of usage and use ChatGPT plus for 99% of my chats, which I find more effective anyway. Sintra's image generation and social media post generation is just awful. If you want something that very clearly looks AI generated and feels super budget for logo, photo or any marketing material creation, then go for Sintra. This is absolutely not for serious, premium businesses which I classify myself as. Instead of feeling like a productivity tool I can rely on, it now feels like something I have to ration and take with a huge pinch of salt everything it does and says. I was excited about the platform initially, but this pricing and credits model has seriously damaged my trust in the service. Customer service is all AI up front and very difficult to reach a real person - even when you do get through on email, it's dubious as to whether you're actually speaking to a human. Messages from support were cold and matter of fact, very dismissive. One of Sintra's USPs for me was all its connections to other tools and how it felt like it was 'Mission Control' for my business. These connections and integrations are very flaky and need resetting pretty much every time I use them. Most times if I switch between desktop and mobile, the integrations don't persist, so you can't do the same things on both. 9 times out of 10, the integrations fail anyway when being used. I am now stuck with a product I have paid a year upfront for, with no hope for a refund and a tiny amount of credits to use every month - what a waste of money for my small business. My recommendation to Sintra would be to stop trying to improve your profit margins to the detriment of your current customers and their longevity with the platform - recent reviews on the platform speak for themselves. I'm on community sites with Sintra on Facebook as well, and what used to be a steady stream of reviews praising the product and its new features has slowly turned very sour, coinciding with the introduction of credits. Stay away and use another tool that feels genuinely useful and much better value.
**1 Star**
**1 Star** I purchased an annual subscription because the plan included unlimited AI helpers. That unlimited access was the primary reason I committed to paying for a full year. After I subscribed, the company changed its plans and removed the unlimited features I had paid for. When I contacted customer support, I received canned, copy-and-paste responses that did not address my concerns. I asked for a fair solution or a partial refund for the unused portion of my annual subscription because the service had changed significantly, but my request was denied. From my perspective, this felt like a bait-and-switch. I paid for one set of features and then found those key benefits had been changed after I had already committed to a yearly subscription. The way this was handled reflects poorly on the company's customer service and business practices. Instead of working toward a fair resolution for a long-term customer, they relied on generic responses and refused to address the fact that the service I purchased had materially changed. I cannot recommend this service based on my experience. I hope the company reevaluates its business practices, communicates major subscription changes more transparently, and treats existing annual subscribers more fairly.
Really poor platform
Really poor platform, doest do more that what chatgpt or claude can provide
I have been using Sintra for a long…
I have been using Sintra for a long time... Then they bought in a credit system which is just an awful money grabbing system which is very poor. You also cannot speak to a human to rectify, everything is AI automated. Very very poor customer service, they were quite happy just to say bye and not help at all. See my complaint below: I am writing to formally lodge a complaint regarding the recent transition to your new credit-based system, and more specifically, how your bots are currently consuming those credits. Since the rollout of this change, I have noticed a massive and unacceptable spike in credit consumption. The bots appear to be optimized to use as many credits as possible for tasks that previously required minimal resources. Instead of delivering efficient, streamlined results, the system is now generating bloated, repetitive, or unnecessarily multi-staged responses that seem designed solely to deplete my credit balance and force a paid top-up. As a customer, I expected this system update to improve the user experience, not serve as a predatory mechanic to artificially inflate usage costs. This shift feels incredibly disingenuous and deeply damages the trust I placed in your platform. To resolve this issue, I request the following: - A thorough review of my recent account activity and credit usage logs. - A refund or adjustment for the credits wasted on inefficient, artificially inflated bot responses. - Clarity on what steps Sintra AI is taking to optimize bot efficiency so users are not penalized for system-side verbosity. If this is the permanent direction of the platform, I will have no choice but to cancel my service and take my business to a competitor with more transparent and fair pricing practices.
