Cosmo (formerly ClassUp)Reviews of cosmoai.com

I am writing to express my deep dissatisfaction with your platform. Having used several online and in-person tutoring services over the years, I can say with confidence that this has been the most disappointing experience to date. Your sales process was incredibly aggressive—pushing us to sign up quickly with promises of results, personalized attention, and an advanced AI-powered experience. Unfortunately, what has followed has been anything but. The platform itself is poorly designed and unintuitive. The quality of instruction has been subpar, and there seems to be little thought given to actual educational outcomes. Your use of AI feels more like a marketing gimmick than a helpful tool—it lacks the intelligence, adaptability, and relevance needed to support meaningful learning. Worse still, your system for matching students with the right instructors has been chaotic. Despite claims of limited availability, nearly every time slot appears open—yet we’re told to rush to book. There is also a significant language and communication barrier that has made it nearly impossible to get clarity or support. Overall, the service lacks direction, consistency, and credibility. It feels like a company with an identity crisis, caught between selling a tech solution and actually delivering a quality educational experience. I regret signing up and would not recommend your service to others. At this point, I would have had a far better outcome using self-guided workbooks or teaching my child myself. I hope you take this feedback seriously and make the necessary improvements—for the sake of other families who may not yet realize what they’re signing up for.

I never thought my son would get excited about math, but Cosmo just makes it click for him!

ClassUp lets my child learn at her speed! The learning partner helps change lessons to match how she's doing.

I'm impressed with my child's math tutor! Zain is dedicated and makes sure he gets each topic. My child feels good asking questions, and we're so thankful for her help!

Great Teaching, But Extremely Pushy Sales Tactics The first free session was excellent—the teacher was engaging, interactive, and made the class enjoyable. My child loved it, and the learning experience itself was great. However, the business practices were highly unprofessional. From the moment I filled out the registration form, the agent was relentless. There was no upfront information on tuition fees—I was first pushed to take an assessment and a free class before they would disclose pricing. At the end of the session, I was pressured to commit to a package immediately. When I said I needed time to discuss with my spouse, the agent insisted I turn off my video and call him right away. The level of urgency and sales pressure made me very uncomfortable. To make matters worse, just an hour after the class, I received a text criticizing my child’s writing with screenshots, stating that their essay was lacking in detail and would be a major obstacle for school and college applications. While constructive feedback is valuable, this felt like a scare tactic to push enrollment rather than a genuine evaluation. Overall, while the teaching quality was good, the aggressive sales approach ruined the experience.

When I paid nearly $3,000 for a one-year package that included approximately 84 classes supposedly taught by tutors with experience certificates from top universities, I expected quality support for my 14-year-old daughter, who is taking honors algebra. However, the tutor, who appeared to be around the same age as my daughter, was unable to help her solve the problems. This was a troubling sign. Many classes were missed, and when I asked for a refund, I was told I couldn't be reimbursed. Instead, they offered me additional classes as a solution. If the tutors are ineffective, why would I want more classes? I strongly advise against spending your money on this program; it feels like a scam.

Scammers! I signed my son for 12 classes, got just 9.

Wonderful service team. They contacted me to schedule a free trial, sent me my daughter's progress reports, and helped us reschedule many times.
