Compile & run
Builds each submission with your gcc flags and runs your test cases.
Pipeline · Compile
Compile, grade, and analyze C labs with autOScan.
It runs your tests on every submission and flags banned functions, copied code, and AI-generated work, so you grade with the evidence in front of you.

One pass that compiles, checks, and grades every submission
autOScan turns a zip of C submissions into a graded run, building, testing, and flagging each one against your lab policy, so you grade with the evidence in front of you.
Banned-function scan
Flags disallowed calls like system or exit in every lab.
Pipeline · Scan
Similarity detection
Surfaces suspiciously similar submissions across the cohort.
Pipeline · Compare
AI-code detection
Scores AI-style evidence in each submission, traced to lines.
Pipeline · Detect
Live terminal
Runs any submission in a sandboxed shell, with Valgrind one click away.
Review · Terminal
Per-lab policies
Define the compiler flags, files, and tests for every lab.

From upload to grades
From a folder of submissions to graded results.
Five checks run on every submission and flow into one grid: compile, tests, banned calls, similarity, AI. You review the flags, set the grades, and export the feedback.
- First pass, done for you
- Compile, run tests, scan for banned functions, and check similarity across the whole batch before you open a single file.
- You stay in control
- You set every grade and feedback note. Review what the engine surfaced and finalize on your terms.
What a single grading run gets you with autOScan
Upload a zip of C submissions and the engine compiles, runs test cases, flags banned functions, and checks similarity and AI-likelihood, across every cohort, with every grade left in your hands.

checks on every submission: compile, tests, banned calls, similarity, AI
1
zip per lab, the whole cohort graded as one batch
100
