Emma is the AI tutor from Edumentors, a company best known for connecting families with human tutors; Heddy is a KS3 app that exists only as AI tutors plus flashcards. Emma covers more levels and subjects and plugs into a human-tutoring business, while Heddy is narrower and makes a strict promise never to give the answer.
Everything about Emma here comes from Edumentors' own Emma page, read in September 2026. The page is marketing copy and some of it is ambiguous, which I flag below.

What Emma offers that Heddy doesn't
Breadth. Emma's page lists KS3, 11+, GCSE, IGCSE and A-level, and a subject menu that runs from Maths and Sciences through languages, Economics, Law and Psychology. Heddy teaches seven KS3 subjects and nothing else. If your child needs Spanish, Latin or Business, Heddy is simply not the answer.
A human company behind it. Edumentors sells sessions with human tutors, and its navigation includes pages for finding and becoming a tutor. A family that wants to start with AI and move to a person, or the reverse, can do both under one roof. Heddy has no human tutors.
Learning styles and personalities. The page presents three AI tutors with different temperaments: a visual thinker (Emma), a competitive challenger (Rivo), and a patient guide (Tami). Whatever you think of matching a tutor to a learning style, it is a clear product idea, and Heddy does not offer it. Heddy's tutors differ by subject method, not by personality.
Parent reporting. The plan table lists weekly progress reports, session transcripts and a parent insights dashboard at the higher tiers. Heddy offers parents none of this.
Exam framing. Emma is pitched at exam success, with a personal study map and revision tracking. That suits an 11+ or GCSE family more than Heddy does.
Where they genuinely differ
Personality versus method. Emma's three tutors vary in tone. Heddy's seven professors vary in what they teach: Newton has you predict before you observe, Curie builds the particle picture before any equation, Quill will not write your paragraph. One chooses by temperament, the other by discipline.
The answer question. On its page, Emma "explains topics, answers questions, and guides students through personalised learning paths". That reads as a general-purpose assistant that also guides; it does not say it withholds the solution, and I would not claim it does or doesn't without testing. Heddy's position is fixed: four rungs, the top a worked similar problem, and no path to a fifth.
What revision looks like. Emma's page describes quizzes and revision tracking. Heddy's revision is flashcards written by the tutor who taught you, scheduled by spaced repetition, free and unlimited.
Availability is unclear. The Emma page has pricing and a "try for free" route, and also a "Join waitlist" form. I could not tell from the page alone whether Emma is fully open, so check before you plan around it.
Price and the claims to treat carefully
Emma's plan table shows Pro at £29 and Premium at £45, with a free trial described as "first 3 sessions" in the table and as a "5 days free trial" in the FAQ. Those are different terms on the same page, so confirm with Edumentors. The page also quotes improvement statistics; I have not verified them and do not repeat them.
Choose Emma if
- You need 11+, GCSE or A-level
- You want parent reports
- You may add a human tutor
Choose Heddy if
- 13 or over, KS3 or early GCSE
- You want no answer given, ever
- They want to open it alone
Which to choose
Choose Emma if you need 11+, GCSE or A-level support across a wide subject range, want parent reporting, or may want to pair the AI with a human tutor from the same company.
Choose Heddy if your child is 13 or over in KS3 or early GCSE, wants a tutor that will never give the answer to their own question, and will only try something they can open themselves. Heddy is on the App Store.
