Synthesis Tutor

An adaptive AI math tutor for kids ages 5-11 that reacts to every answer in real time.

80/100Safe BetFrom $119/yrPaid

For a 5-11 year old who needs remediation or enrichment, this is the pick we'd make, and the reason is the mistake-handling: the Tutor reacts to what your child just did instead of serving the next worksheet item. Pricing is genuinely tiered — $119/year billed annually for the plain tutor versus $239/year billed annually for the Pro planner, placement checks, and weekly progress emails — so start the no-card 7-day trial and pick Starter unless you specifically want the reporting. Skip it if you need math past K-5 or want a free tool; Khan Academy Kids covers similar ground at zero.

The 30-second take
Biggest gripe

Going month to month costs $29/mo, equal to $348 a year — more than double the $119/year billed annually Starter plan.

Price reality

At $119/year billed annually, Starter undercuts most paid elementary tutoring apps and is a fraction of what a human tutor charges per hour; Pro at $239/year billed annually is the reporting tier; $29/mo month-to-month suits parents who want an exit ramp rather than a year commitment. Live at $480/mo is priced against human tutoring, not against apps — Khan Academy Kids remains the free benchmark.

Synthesis Tutor is a self-paced AI math tutor for children ages 5-11, built by the team behind the experimental school Elon Musk started at SpaceX in 2014. It covers the standard K-5 curriculum and beyond: counting and cardinality, addition, subtraction, multiplication, division, fractions, and algebraic thinking. Every answer is evaluated immediately, and the Tutor adjusts the next step to what your child just did rather than serving the next item in a fixed sequence. Mistakes are treated as the point, not a failure. The Tutor surfaces them and targets the specific gap behind them. Lessons mix hands-on manipulatives with playful screen-based work, so math starts physical before it becomes abstract. Kids move through gamified levels and unlock rewards, and the Pro tier adds a personalized lesson planner, placement checks, session summaries, and weekly progress emails so parents stay in the loop without sitting through every session. The vendor says more than 35,000 families use it. The 7-day trial needs no credit card. Plans run $29/mo billed monthly (equal to $348 a year), $119/year billed annually for Starter, $239/year billed annually for Pro, and $480/mo for Live, which layers six human tutoring sessions per month on top of the AI tutor. Each plan covers up to 7 children. Against free options like Khan Academy Kids, the difference is real-time adaptation and the mistake-handling loop. It is still software for elementary math only.

Key features

  • Real-time adaptive instruction that adjusts to each answer
  • Immediate evaluation and feedback after every problem
  • Full K-5 math curriculum from counting to algebraic thinking
  • Mistake surfacing that targets the specific gap behind a wrong answer
  • Multisensory manipulatives and hands-on lesson design
  • Text-to-speech read-aloud of instructions and answer choices
  • Gamified level progression with unlockable rewards
  • Personalized lesson planner on the Pro tier
  • Placement checks on the Pro tier
  • Session summaries and weekly progress emails on the Pro tier
  • Live human tutoring, six sessions per month on the Live tier
  • Family plan covering up to 7 children
  • Runs on tablet and desktop
  • 7-day free trial with no credit card required

Behind the verdict

The thing that separates Synthesis Tutor from the stack of kids' math apps is the feedback loop. The Tutor evaluates every answer immediately and adapts the next step to it, and the marketing copy's clearest claim is also the most substantive: mistakes are expected, and customized instruction targets the gap behind them. That is the behavior parents describe in the testimonials on the site — one mother writes that her seven-year-old "no longer feels intimidated by making a mistake," and another says her 10-year-old "went from hating math to asking to do Synthesis Tutor." Confidence repair is the real product here, not the worksheet content. The curriculum is honest about its scope: counting and cardinality, addition, subtraction, multiplication, division, fractions, algebraic thinking. That is K-5, and the site says it goes "much further" than the standard K-5 curriculum, but there is no middle school or high school material. The multisensory angle — manipulatives plus playful screen lessons — is the stated method for kids who need a hands-on entry point; Jane's mom calls out exactly that in the testimonials. Note the vendor's own framing: the Tutor is screen-based on tablet and desktop, so a fully screen-free household is not the buyer. The tiers now do real work. Starter at $119/year billed annually is the tutor plus the full curriculum and the lesson map, with up to 7 children on one plan. Pro at $239/year billed annually adds a personalized lesson planner, placement checks, session summaries, and weekly progress emails — the reporting layer a parent who wants visibility actually needs. Monthly is $29/mo (equal to $348 a year), so annual Starter saves you over $200 versus paying month to month. Live at $480/mo is six human sessions a month layered on the AI tutor; at that price it is a deliberate hybrid purchase, not an upgrade you drift into. Where it does not fit: families needing secondary math, households that want to spend nothing (Khan Academy Kids is free and covers similar elementary ground), and anyone who wants human tutoring as the primary format at low cost — Live is $480/mo. The vendor does not name the underlying AI model anywhere in the homepage or pricing page, so we cannot tell you which model powers the Tutor. We also found no documented integration list. What we can say is that the trial requires no credit card, so the honest advice is to test the mistake-handling with your own child for seven days before committing to a year.

Limitations

  • Coverage is limited to K-5 math topics (counting, addition, subtraction, multiplication, division, fractions, and algebraic thinking) for kids ages 5-11, with no middle school, high school, language arts, or science content.
  • Sessions are delivered on tablet and desktop, not as an API or developer product.
  • The vendor's homepage and pricing page do not name the underlying AI model, so the model powering the Tutor cannot be confirmed from the available evidence.
  • The reporting layer — personalized lesson planner, placement checks, session summaries, weekly progress emails — sits on the Pro tier at $239/year billed annually, not on Starter.
  • Human tutoring is only available on Live at $480/mo for six sessions a month.

Hidden costs & gotchas

What the public pricing page doesn't put in bold. Captured from pricing-page footnotes, contract terms, and recurring complaints.

  • Going month to month costs $29/mo, equal to $348 a year — more than double the $119/year billed annually Starter plan.
  • The personalized lesson planner, placement checks, session summaries, and weekly progress emails are Pro-only, so you need $239/year billed annually to get progress reporting.
  • Human tutoring is only on Live at $480/mo for six sessions a month, which is a separate purchase from the $119–$239 a year AI plans rather than an add-on to them.
  • The family cap is 7 children per plan, so a larger household needs a second plan.

Real-world workflow fit

Concrete scenarios for the personas Synthesis Tutor actually fits — and what changes day-one when you adopt it.

Parent of a struggling 7-year-old

You start the 7-day no-card trial, let the Tutor's placement-adjacent lessons surface where the gaps are, and sit nearby for the first session while the Tutor reads instructions aloud.

Outcome: Your child gets practice that targets the specific gap behind each wrong answer instead of repeating a worksheet, and you decide within a week whether to commit to $119/year billed annually.

Homeschooling parent teaching multiple children

You pick lessons from the map for each child under one family plan covering up to 7 children, and let the Tutor handle math while you teach other subjects.

Outcome: Math runs itself for an hour a day, and you keep the broader curriculum moving without a separate math block to prepare.

Parent who wants visibility without sitting in

You take the Pro tier at $239/year billed annually so the personalized lesson planner and placement checks set the path, then read the session summaries and weekly progress emails.

Outcome: You see what your child covered and where they slipped without attending every session.

Workflow scenarios generated

Setup time & first value

How long it actually takes to get something useful out of Synthesis Tutor — broken out by persona, not the marketing-page minute.

Most parents get a child into a first lesson the same day: sign up for the 7-day no-credit-card trial, pick a level from the lesson map, and let the Tutor take over. Expect 10-15 minutes of adult help on session one for a 5- or 6-year-old, mostly confirming audio works for the read-aloud instructions.

Switching to or from Synthesis Tutor

How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.

Migrating in
  • →From Khan Academy Kids: start the 7-day trial and use the lesson map to place your child at the topic where free practice stopped adapting.
  • →From a worksheet or textbook curriculum: pick the matching K-5 topic from the map and let the Tutor's immediate evaluation replace your marking.
  • →From a human tutor: run a month of Tutor sessions first, then use Live at $480/mo for six sessions a month if you still want a person in the loop.
Migrating out
  • ↗To Khan Academy Kids: free elementary practice if you want to spend nothing; you lose the real-time mistake-targeting loop.
  • ↗To a human tutor: hand over once your child is past K-5 math, since Synthesis stops at algebraic thinking.
