I’ve used several AI platforms over the past couple of years, including GPT Pro, but I found that information I entered would change or disappear over time, making it frustrating to compare reports without re-entering everything. It also became noticeably slow. Although I was initially hesitant to try Sintra due to the cartoon-style avatars, I’ve been impressed by how fast and accurate the platform is. The chat formatting is tailored for different business needs, which is genuinely useful. Overall, I’m a big fan.

MIxed Results

1. Most of the time I felt the helpers being more like giving me recommendations instead to actually able to do things as one expects from AI agents / bots.
2. Unable to create MS Excel documents.
3. Unable to have videos in Brain AI and analyze them.
4. Social Media Manager works amazing, other automations are good too.
5. The responses are usually to long and repeated text.
6. The daily questions are repeated too frequently if I skipped, this should not be happening for at least 4 to 6 weeks.
7. Mixing up the context sometimes.
8. For Integration of apps, no update is provided is their is any issue or request to system admins are rejected.
9. Shopify integration is eagerly awaited.

We're very thankful for your thoughtful and detailed review, Ayyaz. This kind of feedback is helpful for us as we keep improving Sintra.

We're happy to let you know that you can have helpers create Excel (.xlsx) files if you connect your Google Drive and ask the helper to generate the sheet file and upload it there. We hope to introduce .xlsx to Canvas for convenient editing access soon.

Brain AI can store videos in .mp4, .mov, .avi, and .webm formats for social posting, and the uploaded visuals are analyzed for media context.

For more automation options, we’re currently testing a new “tasks” feature that essentially lets you build your own automations as tasks your helpers do at set times. We can't wait for you to try it!

We’ll look into making your daily questions less repetitive. To make the replies more concise, you can set the Message Length setting to Short in your helper's Conversation Settings.

If you have specific workflows in mind, reach out at help@sintra.ai and we’ll be happy to walk you through what’s possible and what’s coming next. Thanks again for helping us make Sintra better! 💛

I like most of the helpers

I like most of the helpers, but some seem to do a very similar thing aka you could do with less helpers IMO

They also don't quite go as far as I would like RE automations and reminders. I have to remember quite a lot, remind myself of the conversations (and when you're having half a dozen that's quite a lot)

When I work hard with the helpers they do a good job, but the level isn't at previous AI I have in my business....I have to be the main driver as they often don't take things from brainAI and I have to resubmit photo's for example

I could do with knowing how your top customers have used the helpers because they make suggestions which are confusing and often work for works sake

All in all pretty helpful, I've got a new site which is simple and clean and I really needed that but without that I don't think I would be using the service

Thank you so much for your honest review. It’s great to hear Sintra has helped you launch a new, clean site – congratulations! 🙌

You’re right that some helpers have overlapping features, and we’re working on making their roles and abilities clearer and more integrated so you don’t have to juggle as much or repeat yourself. Automations and reminders are areas we’re actively improving. If your helpers are struggling with fetching relevant files from Brain AI, renaming the files and using the names as keywords in your prompts might help.

Offering more public examples of how top customers use the helpers is something we really need to make happen! If you haven't joined our community group on Facebook yet, we recommend it as a place for inspiration and discussion. You are also always welcome to email us at help@sintra.ai, let us know what you’re looking to achieve, and we'll do our best to help. 💪

Sintra is a tool beyond expectations

Sintra is a tool beyond expectations, the first week I have a well gap analysis on our competitors and a completely new social media calendar with posts on all of our social accounts. I also have some corporate documentation that was well needed that took only about five minutes to create. I believe this would've taken three days by one of our employees.

Blunt Review for Sintra AI

Every business niche might have different experiences with AI, but for mine, Sintra AI was a complete disappointment.

I tried using Sintra to handle my Facebook and Instagram posting, and the AI simply would not listen. Week after week, it ignored the instructions I clearly gave it. Out of roughly 10 weekly post suggestions, about 8 were focused on the exact topics I told it never to post again. It was like talking to a brick wall — the AI didn’t learn, didn’t adapt, and didn’t improve, no matter how many times I corrected it.

Then there was their “leave a review on TrustPilot and get a free month” promo. I use a pay-as-you-go card for my business expenses, so I didn’t load it since I wasn’t supposed to be billed. Sintra still repeatedly tried (and failed) to charge me for the month I was owed for free. I contacted support, was told it was fixed, and to ignore the payment emails.

Except the payment emails never stopped.
Every few days: “You missed a payment…”
No — I didn’t. It was a free month. You confirmed it.

And yet the same emails continued, over and over. It became annoying and unprofessional.

So yes, maybe Sintra AI works for some people. But for my business, it did not follow instructions, did not learn, did not improve, and their billing system made the experience even more frustrating. Honestly, it caused more problems than it solved.

Thank you for giving Sintra a try for your business, Stephen. We are sorry for the frustration you experienced. This is not the experience we wanted for you.

Your original email was incorrectly marked as spam in our inbox. Thank you for contacting us again, as this allowed our team to spot and fix the issue right away.

We can see that Stripe sent one notification about the failed charge attempt, and any further notifications came from automated marketing emails. While we can’t edit those messages individually, you can unsubscribe from them at any time.

We wish we’d known you were having trouble with applying instructions for Facebook and Instagram posts. If you’re open, we’d appreciate a bit more detail about where and how you set those instructions. We're positive that we can help you resolve this quickly.

Our team is always ready to assist you at help@sintra.ai and via Help chat. We once again apologize for the experience you had so far, and want to thank you for sharing it with us to improve our operations.

Incredibly helpful and accurate

I'm blown away by how helpful this app is for my business. I uploaded my books and other material that I've written, gave websites and the content created was 100 percent accurate to my voice because it's from my own material. It doesn't have that typical AI cadence and use of overblown terms (hello, "you are not alone"). I was able to create a year's worth of emails and three months of social media within one hour. But again, it's more than fast: it sounds like me because it's from my own content. So, if you're on the fence, I highly recommend Sintra.

Almost 5 Stars from a Mid-Sized Nonprofit

I’ve been using Sintra.ai for about a month, and so far, I’m impressed. As an experienced executive director of a growing mid-sized nonprofit, I often run into resource limitations—especially when it comes to hiring staff for marketing, copywriting, and strategic planning. Sintra has filled many of those gaps.

Its tools have been especially helpful for copy-editing grant proposals, summarizing lengthy reports, and compiling data from multiple documents. With its support, I’m able to accomplish significantly more each day. Overall, I’m very pleased with the platform. My only concern is that our organization may not be able to sustain the cost of the full plan without a discount.

I would happily give Sintra five stars if the AI email feature were more reliable and integrated directly with Gmail, and if the platform didn’t experience occasional lag in Google Chrome—though that may be related to my simultaneous use of Grammarly. It feels like they are still perfecting and refining the system's capacity.

Sintra's customer service is quick and helpful in troubleshooting issues.
