Goblins vs. Edia

Why we built Goblins

Goblins lets students speak and draw to learn math. That lets Goblin, the tutor, pinpoint exactly where mistakes and misconceptions arise. Teachers usually arrive skeptical. They have tried tools like this before. The moment that converts them is watching a student who never engaged work a whole problem through, in their own writing. The Gates Foundation funds Goblins.

They can't just look on somebody else's screen and put an answer down. They can't Google it somewhere and just put an answer down. They actually have to understand what they're doing in order to move on.

It forces them to really think about what they're doing and understand their process. ... They have to prove it. They have to show all of their work and it's been great.

Renee Schuch · 6th Grade Math · Deer Valley

When they're doing the questions in Goblins, it's like I'm sitting there helping them. ... I can go into Goblins and I can look at literally the history of every question to see what the back and forth was.

Why not just use Edia?

No independent body has ever evaluated Edia, and its money-back guarantee is graded by Edia's own model. The marketing promises "8-23% math score improvements" with a refund if scores don't move. The refund trigger is measured by Edia's own internal AI proficiency model, which predicts standards mastery from in-platform work. The state tests the marketing leans on do not decide the payout, and the full contract terms are not public. A guarantee is only as good as who grades it.

With Goblins, verification is direct. Teachers watch live as Goblin works with students, replay every session's written work and conversation, and the free tier runs in a real classroom without a sales conversation. You do not have to trust a dashboard's promise when you can watch the tutoring happen.

  • No Evidence for ESSA entry and no What Works Clearinghouse review. Every efficacy number in Edia's marketing is self-produced.
  • The 15 to 30 percent chronic absenteeism reduction claim has no discoverable backing artifact, not even a self-published case study.
  • Edia doesn't watch students' work as they write, and its tutoring is mostly typed. Students type answers into adaptive practice with diagnostics, benchmarks, and intervention grouping.
  • Celina ISD, Edia's strongest case study, is a pre/post comparison from a year the district overhauled instruction across the board. Nothing separates Edia from the rest of the overhaul or from ordinary year-over-year movement. The score gains are real. Nothing shows Edia caused them.

Edia's numbers vs. Edia's own documents

Edia's own chart shows its usage groups ranging from -4.6% to +9.7% growth. The marketing calls that 'grew 18x faster.' A usage group going backwards is its own warning, on top of the unfounded multiple. The rest of the numbers have even less behind them.

  • Fulton County "grew 18x faster." The chart behind the claim shows Edia usage groups at -4.6%, +2.8%, and +9.7% growth, with usage self-selected. The lowest-usage group went backwards, and the 18x claim is unfounded.
  • "200+ districts and 500,000 students" is vendor-reported and unaudited. Only about four or five districts have any published results data.

Frequently asked questions

Edia's money-back guarantee is graded by Edia's own internal AI model, not by the state tests its marketing cites.

  • The refund trigger is Edia's internal proficiency model predicting standards mastery from in-platform work. State test results do not decide the payout.
  • The full contract terms are not public, so districts commit before seeing how the grader works.
  • Goblins asks you to verify instead of trust. Watch the tutoring live, replay every session's written work and conversation, and start on the free tier before anyone signs anything.

No independent body has ever evaluated Edia. There is no Evidence for ESSA entry and no What Works Clearinghouse review, so every efficacy number in Edia's marketing is self-produced.

Only about four or five of Edia's claimed 200-plus districts have any published results data.

  • The 200 districts and 500,000 students figures are vendor-reported and unaudited.
  • Edia's press names San Francisco, Cincinnati, Denver, Wichita, and New York schools as customers. That proves the sales motion works, not that the tutoring does.
  • With Goblins the reference check is your own classroom. The free tier runs without a sales conversation, and you watch the sessions yourself.

Named logos tell you who bought. A class period tells you what they got.

Edia doesn't watch students' work as they write, and its tutoring is mostly typed.

  • Students type answers into adaptive practice with diagnostics, benchmarks, and teacher-directed intervention grouping.
  • Goblins students draw and speak their math. Goblin follows the strokes and the spoken reasoning live and catches a misconception at the step where it starts.
  • Goblins runs its own custom models and custom software to read even messy handwriting, aided by persistent memory of how each student works.

Students talk with a tutor that can see what they are doing, and teachers see the difference first in the students who never engaged.

Goblins shows every student's work live and sends real-time notifications for disengagement, struggling, and misconduct that pinpoint where to look.

  • The live classroom view shows who is stuck this minute, so you can pull a small group on the spot.
  • Session replays keep every problem's written work and the full tutor conversation.

You see the stall as it happens, not in Friday's report.

Edia does not publish pricing. Districts get a number in a sales conversation, with free pilots offered.

  • There is no public price to compare or budget against before the sales call.
  • Goblins is free for teachers, with 15 live help-enabled problems per student each month, standards-aligned assignments, worksheet uploads, and teacher avatars, no credit card.
  • Goblins Max, priced per school or district, makes live help unlimited and adds standards and engagement reporting.

Only one of these numbers exists before a sales call.

Goblins students speak and draw in whatever language they think in, and Goblin keeps up.

  • Edia markets support in more than 100 languages, per its own materials.
  • Goblins never caps languages at a number and adds new ones whenever a classroom asks.

Yes. Goblins complies with COPPA, FERPA, and student data privacy laws in all 50 states.
