The operating system for your SAT academy.
Most platforms hand you an empty shell and tell you to upload your own questions. VindicaOS shows up loaded: 4,700+ tagged questions, and Seneca, a measurement brain, already running underneath. Every answer becomes a diagnosis, a prescription, and a parent report that cites real numbers. Automate as much of it as you want, under your own name.
No card, no setup fee. $10 a student, free for nonprofit schools.
A trusted partner and provider to SAT academies and tutors across Korea
Your program runs on six disconnected tools.
A spreadsheet for scores. A separate mock platform. Chat apps for parents. A drive full of PDFs. Nothing talks to anything, so nobody actually knows what each student needs next.
- Mock scores in a spreadsheet no two forms can compare
- Homework assigned by gut, not by weakness
- Parent updates written by hand every week
- No single place to see who's stuck, and where
- Weeks spent scanning PDFs and uploading questions one by one
- Rasch-equated scores that are comparable across every form
- Homework auto-targeted to each student's real weak spots
- Parent reports generated from the data, cite-checked
- One dashboard: every student, every domain, live
- A fully tagged bank of 4,700+ questions, loaded and ready to assign
Everything a serious SAT program needs. Nothing it doesn't.
Rasch-equated mock tests
Full Bluebook-faithful mocks scored by an ability model, not a flat curve, so "she did better on the harder test" is finally a true statement. Scores stay comparable across every form you run.
A live classroom, in real time
Push a question to the whole room, watch answers land as they happen, and spotlight the one worth walking through. See who's off-task before they fall behind.
Homework that targets itself
Seneca prescribes each assignment from the student's own miss-pattern. Approve it in one tap, or let it run fully automated. Your call, never behind your back.
Parent reports that don't lie
"Olivia holds 90%+ on inference; the ceiling now is vocabulary." Every claim traces to a stat, no filler.
4,700+ questions, already loaded
SAT-style items and Bluebook-faithful mocks are in the platform on day one. Nothing to scan or upload. Build your own sets on top, or import your own questions, and see per-question analytics on what your students actually miss.
The depth shows up after the demo.
Anyone can screenshot a dashboard. The difference is the machinery underneath: how assessments get built and scored, how students and teachers are actually run, and how every question is kept honest.
The assessment pipeline
One path from a student's first diagnostic to their next mock. Nothing bolted on, and nothing that stops being comparable across forms.
Student management
Every student has a record that knows them, not just a name on a roster. You see who is stuck and where, live.
Teacher management
Run the people, not only the roster. Roles, feedback, and one shared source of truth every instructor reads from.
Question quality
4,700+ items, every one tagged and continuously checked. Answer keys are never touched by a machine.
No mockups. The actual product.
Every screen below is the live software, running a real demo academy. Not a rendering, not a someday-promise.
One honest loop, run for every student.
Underneath every VindicaOS academy runs Seneca, a measurement brain, not a content dump. It finds where each student actually is, prescribes the fix, and checks whether the fix worked. Then does it again, as automatically as you want.
Find the real weak spot
A diagnostic and every mock feed one ability estimate per domain, so you target the bottleneck, not the guess.
Prescribe the fix
Targeted practice and live review aimed exactly at that domain, assigned by the teacher, tracked to completion.
Prove it moved
The next mock re-estimates the same domain. Did the score move? The loop shows you, and starts again.
Your brand. Not ours.
Students and parents see your academy: your name, your color, your domain. VindicaOS is the engine underneath; you are the name on the door. Bring your own questions if you have them, too. What you upload stays yours to own and to stand behind.
From the people who run on it.
Directors, instructors, and students at SAT academies and tutoring studios across Korea. Names changed, words theirs.
"Report night used to be four hours of copy-paste. Now the per-student numbers are already written up, so I spend that time reading what actually changed instead of assembling it. It flagged two kids who had quietly stalled before I would have noticed."
"New instructors used to need a full term to calibrate. Now they read the same ability estimate I do, so a 1400 means the same thing across the whole room."
"I could watch my reading score actually move between mocks instead of bouncing around at random. Seeing it hold at the higher number is what kept me going."
"It stopped handing me random sets. Every week it is the exact thing I keep missing, so practice finally feels like it is going somewhere."
Run one cohort on it. You won't want to go back.
Import your students, run a mock, send a report, and watch the whole program surface in one place. The first cohort is free. After that it's $10 a student, and free for nonprofit schools.
