Medly AI Review: Why This Viral Study App Might Be Wasting Your Time (And Money)

Medly AI Review: Why This Viral Study App Might Be Wasting Your Time (And Money)

If you're a student on TikTok, you've been bombarded. Study influencers are everywhere promoting Medly AI with promises of personalised learning, AI powered marking, and guaranteed grade improvements.

I'm Aadam, and I've been tutoring GCSE and A Level students for over five years at SHLC. When a new study platform claims to revolutionise revision, I pay attention. So when Medly AI started appearing in every student's feed, I investigated.

What I found was concerning. A detailed analysis by 1st Class Maths on YouTube (titled "What you're not being told...") exposed serious flaws. Then I checked Trustpilot reviews, student forums, and TikTok comments. The picture that emerged was troubling.

Medly AI Review: Why This Viral Study App Might Be Wasting Your Time (And Money)

This isn't an attack on an app people have spent their efforts, time and money on. It's crucial to protect students and parents from wasting precious revision time and money on something that might actively harm exam preparation.

What Is Medly AI?

Medly AI is an online revision platform targeting GCSE, A Level, IB and SAT students. Founded by NHS doctors Kavi Samra and Paul Edwards, it raised £1.7 million in funding from Eka Ventures and claims to serve over 10,000 students.

Their promises:

  • AI powered personalised learning
  • Exam board specific content (AQA, Edexcel, OCR)
  • Intelligent marking with instant feedback
  • Predicted exam papers
  • Grade improvements based on "Bloom's 2 Sigma research"

The cost: Around £25 per month, or £100+ for annual plans (though they frequently run "save 48%" discount promotions).

What caught my attention: Thousands of students paying £300+ annually for something that claims to replace tutoring. If it works, that's brilliant. But if it doesn't, that's students losing time and money during critical revision periods.

Problem 1: The Broken Marking System

This is the most serious issue. Medly's entire value proposition rests on AI marking that provides accurate feedback. But the investigation found it's fundamentally broken.

The "Medly Roulette" Experiment

The 1st Class Maths investigation tested whether the marking was consistent. They submitted the exact same essay multiple times to see if they'd get the same score.

Result: The identical essay scored anywhere from 27/35 to 35/35 depending on when it was submitted.

Think about that. The same work, word for word, receiving wildly different marks. How can a student learn from feedback when the feedback itself is random?

Accepting Complete Nonsense

The investigation then submitted deliberately irrelevant text to test whether the AI actually reads content or just checks superficial metrics like length and sentence structure.

Test 1: They copied the answer from one English question and pasted it into a completely different English question on an unrelated topic.

Score: 31/40. The AI gave high marks despite the content being entirely irrelevant.

Test 2 (This one's shocking): They submitted the lyrics to Boney M's "Rasputin" as an English essay answer.

Score: 6/40. Ridiculous, but it scored something.

Test 3 (Even worse): They submitted The Queen's Christmas Message from 2000 as an essay answer.

Score: 40/40. Perfect marks for completely irrelevant content.

This proves the AI isn't reading for content, understanding, or accuracy. It's rewarding length, sentence complexity, and nothing more.

Real Student Reviews Confirm This

Trustpilot reviews from actual users echo these problems:

"The AI marking system, particularly for extended written answers, remains a significant pain point. Inconsistent re-marking: pressing the mark answer function a second time frequently results in a different score."

"I find the marking system to be clunky and at times inaccurate."

"Sometimes this AI makes mistakes and it's inaccurate so then you have to restart your whole working out again."

If students can't trust the marking, the entire platform becomes useless. Worse than useless actually, because students think they're learning when they're not.

Problem 2: Testing A Level Content on GCSE Students

Medly claims to be "quality checked by experienced teachers" with content perfectly aligned to exam board specifications. The investigation found this was false.

Content Beyond Specification

For multiple exam boards, the app includes topics officially listed as "not assessed." Students waste time learning content that will literally never appear on their exam.

Examples found:

  • AQA: Rationalising two term denominators and completing the square when x² ≠ 1 (both explicitly listed as not assessed by AQA)
  • OCR and Edexcel: Numerous topics marked as not assessed but included in the app

Actual A Level Content in GCSE Sections

Even more concerning, A Level topics appeared in GCSE sections:

  • Trapezium rule (A Level)
  • Logarithms (A Level)
  • Advanced probability topics (A Level)
  • Position vectors (A Level, found in Foundation tier!)
  • Linear interpolation (A Level, found in Foundation tier!)

Students in bottom sets preparing for GCSE Foundation are being presented with content that belongs in Year 12 A Level maths. This isn't "stretching" students, it's confusing them completely.

Wrong Formula Sheets

When students selected their course, they often received formula sheets for entirely different courses. For example, selecting AQA Higher gave the Further Maths GCSE formula sheet.

Using the wrong formula sheet means students memorise formulas they don't need whilst missing ones they do need.

Remember: each grade improvement is worth around £23,000 in lifetime earnings. Wasting revision time on wrong content directly affects your child's future opportunities and financial security.

Problem 3: The Underwhelming AI Tutor

Medly promotes its AI tutor as a key feature, suggesting it can identify weaknesses and guide learning like a real tutor would.

The investigation found it severely limited compared to free alternatives.

What It Can't Do

When asked general questions like "What are my weaknesses?" or "What topic should I work on next?" the AI couldn't answer. It only addressed the specific question currently on screen.

When asked to generate similar practice questions (a basic feature of good tutoring), the AI admitted it couldn't do that.

Free Alternatives Are Better

The investigation compared Medly's AI tutor to ChatGPT (free) on the same maths problem.

ChatGPT: Provided clearer explanation, offered to generate unlimited similar practice questions, adapted to follow up questions naturally.

Medly AI: Gave adequate explanation but couldn't go beyond the single question, couldn't generate practice questions, and struggled with follow up queries.

Why pay £25/month for an AI tutor that performs worse than free alternatives?

Problem 4: Technical Issues Students Report

Beyond the fundamental problems with content and marking, students report persistent technical glitches:

From Trustpilot reviews:

"Inconsistent stylus input. This is specific to the Medly application. The inconsistency in the drawing and writing interface is disruptive to the learning workflow."

"Struggle to use the canvas or writing feature for maths problems and chemistry as it's very laggy and there's no feature to zoom in."

"The app just keeps loading."

"Some questions which require a table of data seem to have the whole table missing."

From TikTok:

"The papers' content is mixing and some of it isn't even in spec."

"I picked my subjects but when it gives introductory questions it's a blank screen."

For an app charging £25/month, basic functionality should work. Students are paying for a service that frequently doesn't function properly.

Problem 5: The Influencer Marketing Machine

If Medly has all these problems, why is it everywhere? The answer is straightforward: money.

The Payment Structure

The 1st Class Maths creator was offered £600 for three short promotional videos. Other student influencers reportedly earn £300 per video.

For a student, that's massive income. It creates strong incentive to promote the app regardless of whether it actually works.

No Expertise Required

The criteria for becoming a Medly promoter isn't educational expertise or teaching qualifications. It's "how well you can yap in front of a camera."

Teachers are notably absent from the promotional push. The people promoting it are students being paid to promote it, not educators who've evaluated whether it works.

Empty Insights Pages

Multiple investigation found student influencers showing completely empty "insights" pages when demonstrating the app. This strongly suggests they've never actually used it for their own revision, despite promoting it enthusiastically.

Misleading Statistics

Medly's own marketing contains contradictory claims:

  • "74% improved by at least one grade"
  • "74% jumped by two plus grades"
  • "Only 40% gain two plus grades"

These can't all be true simultaneously. Which statistic is accurate? How were they measured? The contradictions cast doubt on all claims.

The Trustpilot Controversy

Most damning: Medly sent emails offering a free month to "the first 200 people who leave a great review on Trustpilot."

This directly violates Trustpilot's terms and conditions against incentivising positive reviews. It means their 4.5 star rating is compromised, unreliable, and potentially manipulated.

When a company needs to bribe users for good reviews, what does that tell you about the product?

What Students and Parents Should Know

The Cost Reality

At £25/month or £100+/year, you're paying serious money. For comparison:

What £300/year buys:

  • Medly AI subscription (with all the problems detailed above)

OR

The question isn't just "does Medly work?" It's "even if Medly worked, is it worth £300 when better alternatives exist?"

Free Alternatives That Actually Work

For the specific subjects Medly covers, here are proven free alternatives:

Maths:

See my complete resource guide for more.

English:

  • Mr Bruff (YouTube): Outstanding A Level and GCSE English teaching
  • BBC Bitesize: Free, reliable, exam board aligned content

Sciences:

  • Cognito: Clear, concise video explanations
  • Mr Free Science: Exam focused teaching
  • Seneca Learning: Free interactive platform

For AI assistance:

  • ChatGPT (free version): Better explanations than Medly's paid AI tutor
  • Google Bard: Alternative free AI that can explain concepts

These resources are free, proven effective, and don't have the fundamental flaws Medly exhibits.

When Paid Support Actually Makes Sense

I'm not saying all paid services are worthless. But there's a difference between paying for quality and paying for marketing hype.

Paid support makes sense when:

It's qualified teachers, not AI: One-to-one or small group tutoring with qualified teachers like at SHLC provides personalised attention, expert diagnosis of gaps, and adaptive teaching that AI simply cannot match.

It provides genuine expertise: My mock exam marking service offers qualified teacher analysis of exactly where marks are lost and how to improve. This is expert human feedback, not algorithmic guesswork.

It supplements, not replaces, proper study: Good paid tools enhance revision, they don't claim to be complete replacement for textbooks, past papers and structured study.

It's transparent about what it is: Quality services don't need inflated statistics, paid influencer promotions, or incentivised reviews. Results speak for themselves.

The Student Room Verdict

Checking what actual students say on The Student Room (UK's biggest student forum) reveals honest opinions away from paid promotions:

"Medly was ok but it's £25 a month which didn't really seem worth it as there's lots of past papers online."

"I'd say Seneca > Medly > Uplearn."

"All the videos you get on Uplearn you can definitely find a more concise + clear video on YouTube, such as Cognito."

Students who've tried multiple platforms consistently prefer free resources or cheaper alternatives.

Red Flags That Should Concern You

If you're still considering Medly despite everything above, watch for these warning signs:

Red Flag 1: Inconsistent marking. If your child gets different scores for the same work, the feedback is meaningless.

Red Flag 2: Content not matching your exam board. If they're learning topics not on their specification, they're wasting time.

Red Flag 3: Technical glitches disrupting sessions. If the app frequently crashes, freezes, or displays incorrectly, it's not worth paying for.

Red Flag 4: Your child prefers free alternatives. If they're naturally gravitating to YouTube or Maths Genie over Medly, listen to them.

Red Flag 5: No visible progress after 4-6 weeks. If grades aren't improving despite regular Medly use, it's not working.

What I Recommend Instead

Based on my five years tutoring students preparing for GCSEs and A Levels, here's what actually works:

For Self Study

  1. Use proven free resources listed above (Maths Genie, Corbett Maths, etc.)
  2. Complete past papers under timed conditions using SHLC past papers
  3. Track progress systematically using my digital revision planner
  4. Get periodic expert feedback through my marking service to identify exactly where marks are lost

Total cost: Under £50 for the entire year

For Structured Support

If your child needs more than self study:

One-to-one qualified teacher tutoring at SHLC provides:

  • Actual diagnosis of specific gaps, not algorithmic guessing
  • Teaching from someone who understands exam boards intimately
  • Adaptive explanations based on your child's learning style
  • Accountability and structured progression
  • Real human feedback, not AI inconsistency

Yes, it costs more than Medly per month. But you're paying for qualified expertise that delivers measurable results, not AI that marks "Rasputin" lyrics as good English essays.

See my guide on finding the right tutor for more on choosing quality support.

The Bottom Line

Medly AI might improve in future. Perhaps they'll fix the marking inconsistencies, remove A Level content from GCSE sections, align properly with specifications, and stop incentivising positive reviews.

But right now, the evidence suggests:

  • The marking system is unreliable and inconsistent
  • Content includes material beyond specifications whilst missing assessed content
  • The AI tutor performs worse than free alternatives
  • Technical issues persist across multiple users
  • The high ratings appear artificially inflated through incentivisation
  • Students using it aren't seeing better results than those using free resources

For £300/year, you deserve something that actually works. Your child's revision time is precious. Exam pressure is intense. Using tools that waste time or provide false confidence through inaccurate marking genuinely harms preparation.

Before paying for any study app:

  1. Research independently (don't trust influencer promotions)
  2. Check for actual evidence of effectiveness
  3. Look for honest student reviews on forums, not paid testimonials
  4. Ask whether free alternatives might work better
  5. Consider whether the cost represents genuine value

Remember: exams are not "pay to win." The most expensive tool isn't automatically the best. Often the most effective revision combines free quality resources with strategic use of qualified teaching support when needed.

Your child's grades matter enormously. Each grade improvement is worth around £23,000 in lifetime earnings. Make sure you're investing in support that actually delivers results, not marketing hype.
