Written by the company

Synthesis creates learning experiences designed to help kids become confident, capable thinkers. Synthesis began with Teams, an online collaborative problem-solving program for kids ages 8–14, inspired by the experimental school at SpaceX. In Teams, kids work together to solve complex problems, make strategic decisions, communicate clearly, and develop essential human skills like critical thinking, teamwork, leadership, and collaboration. We later built Synthesis Tutor, an AI-powered math tutor for kids in grades K–5. Tutor brings the same focus on deep thinking and high-quality learning to foundational math. Tutor adapts in real time to each child, whether they need extra support, are right on track, or are ready to move faster. Instead of relying on memorization, it helps kids understand the “why” behind math through interactive lessons, visual explanations, and a patient tutor that responds to how they learn. Synthesis Tutor covers foundational math topics including addition, subtraction, multiplication, division, fractions, and early algebraic thinking. Lessons are personalized and designed to build both strong math skills and real confidence. Synthesis is used by families and educators around the world, with programs available for both families and schools. Our mission: Advancing human progress through education, one child at a time.

Great independent math program

This program really does teach your kids math in a thorough but fun way. It has even gotten my son excited about doing flash cards! It does not require a parent or teacher assistance .

This is a great option for kids whose reading and math levels don’t match - there is no reading required but they can go all the way through elementary math at their own pace.

My kids are thrilled

My kids are thrilled; it's their favorite 'game.' Every day they ask for Dad's computer so they can 'play'... I'm also thrilled—little by little they are learning, and not just math, but also English and computer skills. It's a healthy addiction!
I recommended it to a few friends, and it had the exact same effect! Thx!

Fun summer unique learning experience

I enrolled my kid for Synthesis Tutor when he was in grade 2. We find the teaching method is innovative and he learned a lot with fun. He asked to do Synthesis again and we found it is about time to join Synthesis Team. It was a great experience and he looked forward to to go online every day to complete the tasks and engage. He felt greatly encouraged every time he got endorsed by the peers. I highly recommend every student to try Synthesis Team.

Weirdly positive experience with these folks

Weirdly positive experience with these folks. The app is very good obviously, but that is not the point of the review. Primary experience was that I thought I had canceled but actually did not seem to have in fact canceled. I wrote them an angry email accusing them of failing to honour a cancelation.... and they 1) basically showed that I had not in fact canceled, even though I thought I did, 2) nevertheless refunded nearly a year of payments when it was not being used (it was in fact used for two months during that period, unbeknownst to me).

Anyway this was just *very* surprising behaviour from a company because I am absolutely used to simply being nickeled and dimed by every business I interact with now. Especially in this instance, where it now appears that I had actually dropped the ball and in fact failed to cancel. They also went to the trouble of investigating why I wasn't receiving emails and showed a screenshot of their system showing bounced messages.

Basically just very honourable and impressive customer service and made me immediately trust them and want to actually re-subscribe, though for real this time 😂😂.

We love Synthesis

We love Synthesis.
We began using synthesis tutor the summer leading into first grade , with the intention of exposing our kids to math in a way that wouldnt interfere with their learning at school but instead would help our kids feel confident while learning in a classroom next to their peers. We saw such a huge improvement in our kids confidence at school- he was participating, not shutting down with new information anymore. He started embracing school . We like to use synthesis during summer, winter and spring break- to maintain his studies off campus. This year we were able to do the synthesis camp, and we loved the experience. He learned to work in teams and developed confidence in different human skills with the help of AI.
He is in 3rd grade and has been using it for two years, he is MAP testing at the top of his class.

I think synthesis is a great tool to expose your child to learning in a no pressure environment so that they can learn to succeed when pressure arises.

Highly recommend trying it.

Synthesis summer camp was a great experience!

My son Martin had a genuinely valuable experience with Synthesis Summer Camp. At first, he sometimes struggled with the uncertainty of the challenges, working with different personalities, and figuring out his place on the team. But that was exactly where the growth happened. As the camp progressed, I watched him become more engaged, confident, and comfortable collaborating with others.

The experience went far beyond solving games or puzzles. Martin practiced communicating, managing frustration, adapting when things did not go as planned, and working through problems as part of a team. I told my husband that it almost resembled adult work life. I regularly join calls with different personalities and encounter many of the same teamwork challenges that Martin was learning to navigate at such a young age.

Synthesis gave him a safe place to practice those skills while he is still young. He came away with lessons that I believe will serve him in school, friendships, sports, and eventually the workplace. Overall, it was a 10/10 experience for us. Although we cannot fit it into our schedule year-round, we will absolutely return next summer.

A truly wonderful experience!

Summer camp was a truly wonderful experience for our 2 daughters... they loved it, made new friends, and were fully engaged throughout. The coaches and support team were amazing... gently guiding the experience while letting the children figure it all out amongst themselves. A unique and rewarding experience for them. Our girls have continued on with the monthly teams program. Highly recommend!!

Synthesis as a Supplemental Coach

We signed our 8 year-old son for the Synthesis Summer camp. It was his first experience using a laptop, mouse, web browser etc. He picked up all those skills very quickly and within a day was managing and scheduling all his Synthesis sessions. He was so engrossed in the content, the games, the discussions with other kids. He would participate in multiple sessions a day. It was truly amazing to see the ownership he took so much so that we signed him up for Teams and plan to continue with Teams as an afterschool activity once school starts. The whole concept and design of Synthesis is pretty spectacular and exactly what we have been looking for in an educational program. the team work, collaboration, discussions, and ambiguity in problem solving are all skills for now and the future. I can't wait to see what other offerings Synthesis may offer in the future. We highly recommend Synthesis.

They Couldn't Wait to Log In

My two boys (ages 11 and 9) absolutely loved the Synthesis Summer program. For the first time, I never had to remind them to log in—they eagerly joined on their own and often participated in multiple sessions each day. It was incredible to see how much their confidence grew over the course of the program. They became noticeably more comfortable contributing to discussions, expressing and presenting their ideas, and engaging thoughtfully with others. It was wonderful to watch them mature in both their communication skills and their confidence. Thank you for creating such an engaging and meaningful learning experience for them.

Real results

Synthesis has been great for my normally quiet, shy kid - she’s grown in confidence, for sure, all while having fun playing games. I wish I had learned about it sooner, so my older child could have tried Synthesis, too!

Synthesis - never left us behind

Synthesis gave not only my daughter, but me as well, the tools, confidence, and even enthusiasm to learn math.

Our daughter is on the autism spectrum, and she truly thrived with a program that builds on her strengths instead of focusing on her mistakes. One of her biggest challenges has always been retaining previously mastered skills while moving on to new concepts. With Synthesis, I never felt like she was being left behind—it always seemed to “catch her” exactly where she needed support.

We also loved the flexibility. We could move between different math topics whenever we wanted, which was incredibly helpful during periods of burnout. That freedom kept learning fresh and enjoyable rather than frustrating.

She completed the entire program spending just 15 minutes a day on lessons and games. As a homeschooling parent who lacks confidence in teaching math, Synthesis was an incredible gift. It made math feel approachable for both of us.

I recommend Synthesis to everyone I know. I honestly haven’t found anything else quite like it.

Thank you so much for sharing this. Your daughter is exactly who we built Synthesis for: a curious learner who deserves to feel supported, capable, and excited about math.

Hearing that the program met her where she needed help, while giving her the flexibility to keep learning through periods of burnout, means the world to our team. We are especially touched that Synthesis helped you feel more confident as her teacher, too.

Please give your daughter a huge hug from all of us. We are so proud of everything she accomplished, and incredibly grateful that your family trusted us to be part of her learning journey.

My Daughter Loves the Turor!

Have tried lots of other math apps with my 7 year old daughter, and while some of them are able to keep her attention and are decent enough for practice… they really don’t do a great job of actually teaching new concepts.
Honestly, Tutor is just on a different level in this respect. I love the way that the lessons are designed to be super interactive, adaptable, and that they are constantly getting her to think deeply about what she is learning.
The Tutor also has a wonderfully warm tone, which my daughter absolutely loves and we are always excited when we log in to find new lessons for her to explore!

Thank you so much for this thoughtful review! We love hearing that Tutor is not only keeping your daughter engaged, but actually helping her understand new concepts and think more deeply about math.

Our team puts a lot of care into making lessons feel interactive, adaptive, and encouraging, and it means a lot to hear that the warm tone has made such a difference for her too. We’re so glad she gets excited to come back and explore new lessons. Please give her a big high five from all of us!

Our 9 and 12 year old LOVE it.

My son has both dyslexia and dyscalculia and keeping him on grade level has involved nonstop tears and frustration....until we tried this. He asks daily (on his own) to do his lessons with this program. This has NEVER happened. We have spent years and a lot of money on various workbooks, programs, tools, and websites. None of it has ever worked for him or helped build his confidence. There has not been a single tear shed doing Synthesis lessons which in itself is amazing. A few days ago he said, "I never understood ______ until today." Our daughter does not struggle in the same ways but despite being very "meh" about math prior to this, she also loves the program. The kids are now competing with each other....to do math....on summer break. Two different kids with varying levels of ability & comprehension are both loving this. My husband and I are absolutely blown away. If you're on the fence about investing into something else, I swear I don't think you'll regret this one.

Marlena, thank you for this. Our whole team read it and it genuinely made our week.

What you shared about your son is exactly why we built Synthesis. Math shouldn't come with nonstop tears, and the fact that he now asks to do his lessons on his own, with real confidence and even a "I never understood this until today" moment, is everything we hope for. That you're seeing it click for both kids, with very different needs, means a lot.

Two kids competing to do math on summer break might be the best sentence we've read all year.

Thank you for trusting us after so many things that didn't work, and for sharing your story to help other families on the fence. We're honored to be part of it.

Amended review

I'll leave the original review below, but I've adjusted my review based on the fact that someone senior at Synthesis reached out to me overnight and was both transparent and respectful.

It's a good product. It just needs to be scalable along with your child's development and it's not that at the moment.

Original review:
Started out loving it, but now I'm angry. Bought a 1yr subscription for my 7yr old daughter. She went through the content in 3 months. You'd think she'd then go through to content for 8yr old but no.

I ask customer support (via email) and got a reply from "Desislava Sapunova from Synthesis" who has poor english and omits important words like "on hold" for my account in his reply.

Basically, the system doesn't upgrade you to the next age/capability bracket after you finish the level of content you register them for. So you're not buying a 1yr subscription with upgrading capability as your child progresses, you're buying a age/stage set of content that finishes when your child does.

Desislava's solution was to suspend my account until they have more content for that age bracket. But my daughter has completed that level so how does more of the same improve her capability.

I complained and requested a 9 month refund and have ben totally ignored.

So the tool works. I liked it. My daughter loved doing it. But it's shallow, there's no valuable customer support and I feel ripped off.

Subscription has now been cancelled and I've lost that money I gave over in good faith.

Matt, thank you for updating your review, and for the honest conversation. I appreciate you giving us the chance to make this right.

You've also raised something real. Right now Synthesis is deepest in the earlier stages, so for a child who moves as fast as your daughter, the ceiling shows up sooner than it should. Expanding the content so it keeps pace as kids advance is exactly where our team is focused, and feedback like yours is a big reason why.

I'm also sorry the support experience wasn't clearer. Putting your account on hold should have come with a much better explanation of what that meant and what your options were. Your refund has now been processed, and you can reach me anytime if anything else comes up.

Thank you again for giving Synthesis a shot.

The concept is what make it unique

Well, This app has an amazing concept that focuses on something rarely emphasized in other camps or children’s apps: building confidence. The program does an excellent job of encouraging participants, helping them believe in themselves, and teaching them how to work effectively with others.

What I especially appreciate is the positive and supportive environment they create. In addition, the weekly feedback provided to parents is extremely valuable. It allows us to track progress, understand our child’s strengths and areas for growth, and stay involved in their development.

Overall, this is a thoughtful and impactful program that goes beyond entertainment by helping children develop important life skills such as confidence, teamwork, and self-esteem.

My son cannot get past the division…

My son cannot get past the division assessment although he tried multiple times. It is not due to his division skill but the software has a bug and never moves pass assessment stage. The software is slow, the voice (any voice) is irritating because of the mannerism but you cannot switch it off. After a few weeks my child doesn`t want to play with it.

We’re really sorry your son had this experience. If a student is unable to move past an assessment after multiple attempts, that is not the experience we want at all.

In some cases, this can happen when a device runs out of available memory during an assessment, especially on older tablets, but our team would be happy to look into the specific account and help troubleshoot. We also appreciate the feedback on performance and voice options, and we’ll share it with the product team.

Please email us at questions@synthesis.com so we can help resolve this for your family.

for my six year old- literally a new learning paradigm

for my six year old, this is the first "app" or digital resource that really supports her learning, this is so dynamic it actually teaches me about teaching. I wish these people enormous success so they can keep changing education and building a better learning next generation.
