Share the reports
After approval each student gets the marked paper, short feedback and, if you like, a video explanation in the teacher's voice.
From answer key to criteria
The teacher uploads the answer key; Visolv prepares the points and expected answer for each question, and the teacher edits and approves them.
Reading and scoring handwriting
Student papers are uploaded in bulk as PDFs or phone photos; skewed shots and pencil-written papers are read too.
Each answer is read and a score is suggested against your criteria. Uncertain answers are flagged and brought to the teacher.
Teacher approval and student report
The teacher has the final word. After approval each student gets a link that needs no login:
- The paper marked in red pen (PDF)
- Question-by-question video feedback in the teacher's voice
- Strengths and weaknesses by topic and learning outcome

Frequently asked questions
Are scores finalized automatically?
No. Visolv suggests, the teacher reviews; scores and comments can be changed and nothing reaches the student before approval.
Can papers photographed on a phone be read?
Yes. Skewed or upside-down pages are corrected. For best results keep the whole page in frame with even lighting.
What if the handwriting can't be read?
Unreadable or uncertain answers are flagged and go to the teacher's review list; no score is final without teacher approval.
How is partial credit given?
A score with a short reason is suggested for each criterion in your answer key; the teacher sets the final score.
Which subjects can it be used for?
Open-ended questions in math, science, social studies and language subjects: working, short answers and paragraph responses.
What does the student receive?
The marked paper, a score and short explanation per question and, if you like, video feedback in the teacher's voice.
Whose voice narrates the videos?
A teacher's voice is prepared from a clean 15–30 second recording you upload in the panel. If you don't upload one, Visolv's ready-made teacher voice is used.
Which files can I upload?
Test booklet PDFs with a text layer, single question images (JPG, PNG) and exam papers as PDFs or phone photos. Scanned, image-only test PDFs can't be split question by question.
What if the answer key is wrong?
Every solution is compared with the answer key in the booklet. Mismatched questions go to a review list; you choose the correct option and the video follows it.
