Abaci OneScreen time that builds real math skills

From Paper to Practice

Turn paper math worksheets into structured skill data. Snap a photo, and vision AI transcribes every problem — feeding results directly into your child's adaptive practice model.

Try It Now

Most math practice is invisible

Kids do math on paper every day — at school, in workbooks, on scrap paper. None of that practice feeds back into adaptive learning.

Paper worksheets

Practiced offline, never recorded. Your child solves 20 problems at the kitchen table and none of it reaches the skill model.

Incomplete picture

The adaptive engine only sees digital sessions. It stays blind to skills practiced on paper, making inaccurate mastery estimates.

Redundant practice

Without knowing what was drilled offline, the next session reteaches skills your child already mastered on paper.

Four steps to close the loop

From paper to adaptive model in under a minute.

1

Snap

Take a photo of a completed worksheet — handwritten or printed.

2

Parse

Vision AI reads each problem and answer, transcribing faithfully without interpretation.

3

Review

High-confidence results auto-approve. Flagged items get your quick review with inline editing.

4

Learn

Parsed results feed the BKT skill model. The next practice session adapts automatically.

Vision AI that reads, not interprets

Built to transcribe faithfully — not to impress you with corrections.

Faithful transcription

The AI reads what's on the page — no "fixing" answers or guessing intent. Anti-sycophancy by design.

Confidence scoring

Every parsed problem gets a confidence score. High-confidence results auto-approve; uncertain ones get flagged for your review.

Live streaming

Watch the AI's reasoning in real time as it processes each problem. Full transparency into what it sees and how it interprets the worksheet.

Operator detection

Distinguishes addition from subtraction, multiplication from division — even in messy handwriting.

Human in the loop

You stay in control. The AI does the heavy lifting, but you approve what matters.

  • Auto-approval at 85% confidence — most problems need zero intervention
  • Bounding box highlights show exactly which part of the image each problem came from
  • Inline editing lets you correct a parsed answer without re-uploading
  • Re-parse with hints when the AI misses a problem — give it a nudge and retry
  • Resumable review: leave and come back without losing progress

Every problem counts

Parsed worksheet problems feed directly into the Bayesian Knowledge Tracing model. The next adaptive session already knows what your child practiced on paper.
