Bloomy is an adaptive K-12 learning platform for ELA, math and writing, from a Y Combinator Summer 2026 company. Each skill is one sitting of about 25 minutes: instruction, guided practice, then a no-hints mastery check. Its BloomyBot tutor asks guiding questions instead of giving answers and is locked during that check.
About Bloomy
Bloomy is an adaptive learning platform for K-12 English language arts, math and writing, built by a San Francisco company that joined Y Combinator's Summer 2026 batch. It opens with a diagnostic, then builds a personal path through a skill map the vendor sizes at about 700 ELA skills and more than 500 math skills, each mapped to Common Core or state standards. The math content is built on Illustrative Mathematics, and a Writing Studio extends the writing domain.
Every skill is one sitting. A student reads the instruction and a worked example, practises with questions that get easier or harder as they answer, then takes a no-hints mastery check. The AI tutor, BloomyBot, asks questions and gives progressive hints instead of handing over the answer, and it is switched off during the check. That design is the opposite of answer-first homework solvers such as Photomath, Gauth and Mathos AI, which show the full solution to a single problem.
Bloomy suits parents who want structured catch-up or acceleration at home, homeschool families, and school leaders who need a tool for an intervention block. Parents see mastery at the individual skill level and get an email when a message to the tutor looks unsafe or distressed. Photomath now belongs to Google. Teachers who need lesson plans rather than student practice are better served by Lessonsquill, essay marking sits with Edexia, study help for French-language classrooms comes from ImaginAi, and spoken language practice from Speak.

Family plans are sold per subject and per student, with a separate quote process for schools and districts; the exact figures are in the cost section below. The product runs in the browser, and the vendor lists no native phone app on the pages HokAI read.
Pricing
Each family plan covers one student and one subject. 25 a month billed annually). Subjects are priced separately, so a student using ELA and Math pays for two plans, and there is no multi-child discount.
The first family purchase has a 30-day money-back guarantee. School, district and microschool pricing is custom and starts with a demo request. Read from the vendor's family pricing page on 2026-10-28.

Key Features
- Smart diagnostic: Finds which skills a student has mastered and which have gaps, and can read i-Ready and NWEA MAP benchmark data from a school to place the student.
- Mastery gating: A student moves to the next skill only after passing a no-hints assessment, with the vendor stating a 90% pass mark.
- BloomyBot Socratic tutor: Diagnoses the misconception behind a wrong answer and prompts the missing reasoning step, then locks itself during mastery checks.
- Standards-aligned skill map: More than 1,200 skills, about 700 in ELA and 500 in math, each mapped to Common Core or state frameworks.
- Parent dashboard and safety alerts: Shows skill-level mastery and spaced-review status, and emails a parent when a message to BloomyBot looks unsafe or distressed.
- Accessibility controls: Read-aloud on passages, questions and answers, three text sizes, dyslexia-friendly spacing, and keyboard and screen-reader support.
Pros
- Locking the AI during assessments makes the mastery data harder to game than completion-based platforms, which is the main reason to choose it over answer-first apps.
- Subject-by-subject billing lets a parent pay for the one subject a child actually needs instead of a bundle.
- Publishes a dedicated safety and privacy page that states children's data is not sold and not used for targeted advertising.
Cons
- No free plan is listed on the family pricing page, so the 30-day guarantee is the only way to try it risk-limited.
- Per-student pricing with no sibling discount gets expensive for families with several children or several subjects.
- Early-stage product from the Summer 2026 YC batch, so the outcome evidence on the site is school quotes the vendor chose to publish.
Data Handling
- Training-data policy
- The vendor's safety page states that third-party AI providers are not permitted to train general-purpose models on identifiable child data sent by Bloomy, that children's data is not sold, and that it is not used for behavioral or targeted advertising.
Frequently Asked Questions
How much do you pay for Bloomy?
Plans are billed per student and per subject: ELA, Math and Writing each cost $39 a month or $279 a year. A child using all three subjects pays for three plans, and the vendor lists no multi-child discount. Schools, districts and microschools get a custom quote after requesting a demo.
Is Bloomy free to use?
The family pricing page lists no free plan or trial, so every subject is a paid plan. The first family purchase carries a 30-day money-back guarantee, which is the closest thing to a trial. Schools begin with a demo request instead of a self-serve account.
What should you use instead of Bloomy?
Photomath and Gauth suit older students who want a worked solution to a single problem right now. Mathos AI is the free-to-start option if the need is math only. Lessonsquill fits a teacher building lesson plans, since Bloomy is aimed at the student's own practice.
What separates Bloomy from Photomath?
Photomath shows the finished steps to a problem, while Bloomy's tutor holds back the answer and is locked out of the mastery check. That makes Bloomy slower for a rushed homework night and better for filling a gap that keeps recurring. Photomath covers math only, and Bloomy adds reading and writing.
How long does it take to get going with Bloomy?
Families choose subjects on the get-started page, and each subject includes a diagnostic test that places the child before the first lesson. Lessons then run about 25 to 30 minutes each. Sign-in points to a web app, and the vendor's pages list no download.
