Choose a free tool and test with your own text or a one-click sample
Every tool includes a built-in sample loader, step-by-step instructions, and guidance on how to interpret the output fairly.
Free Citation & Reference Checker
Paste up to 25 bibliography entries. We verify DOIs and titles against Crossref and OpenAlex to flag fabricated, year-mismatched, or retracted references commonly hallucinated by LLMs.
- Classifies each entry: Found, Details differ, Possible match, Not found, or Retracted.
- Checks alphabetical sorting and reference age warnings.
- Includes one-click sample bibliography to test immediately.
Free Collusion & Text Similarity Checker
Paste two student submissions side by side (plus an optional assignment prompt to ignore). Our deterministic shingling engine highlights shared passages of 8+ words while masking direct quotes and reference lists.
- Automatically excludes quoted material, bibliographies, and pasted prompt lines.
- Shows overlap % for Submission A and Submission B with colour-coded highlights.
- Never uploads student work to any public web index.
Free Authorship & Writing Style Checker
Paste a known authentic sample from a student alongside a new submission. Compare 6 stylometric dimensions — sentence rhythm, vocabulary diversity (MATTR), contractions, openers, punctuation, and phrase repetition.
- Outputs an overall style consistency score (0–100%) and 6 dimension cards.
- Highlights specific shifts (e.g. sudden em-dashes, disappearing contractions, or uniform sentence lengths).
- Designed to prepare a supportive, evidence-based student check-in.
Free AI Rubric Generator
Turn an assignment brief or exam question into a full criteria-by-level marking grid using UK presets (KS3, GCSE, A level, BTEC Pass/Merit/Distinction, FE/apprenticeship, or University).
- Copy as a table for Word/Google Docs, download CSV, or print cleanly.
- One-click Save to my account sends the rubric straight into Feedback Flows Rubric Builder.
- Observable, student-safe descriptors tailored to UK qualifications.
How to choose the right free tool (and when to upgrade)
Each free tool answers a different question. Combining two signals is much stronger than relying on any single check.
| Classroom scenario | Best free tool | What you paste | Full platform upgrade |
|---|---|---|---|
| Coursework has a bibliography that looks suspiciously polished or unfamiliar | Citation Checker | Up to 25 reference lines from the bibliography | Citation & reference checker (matches in-text citations to the body + semantic claim check) |
| Two students in the same cohort handed in suspiciously similar paragraphs | Collusion Checker | Submission A, Submission B, and optional assignment prompt | Similarity Scoring (automatically checks every marked script against your organisation's private bank) |
| A student's homework reads nothing like their in-class writing | Authorship Checker | One known authentic sample + the new submission (120+ words each ideal) | Writing Fingerprints (multi-sample portfolio baseline + AI style analysis + class ZIP batching) |
| You have a new brief or mock question and need clear marking criteria fast | AI Rubric Generator | Assignment brief + UK qualification level preset | Rubric Builder & Rubric Marking (shared department library + batch AI marking) |
