Spelling and grammar check within the TrueMark editor
TrueMark includes an in-editor spelling and grammar check for all school plans. The tool supports 80+ languages, including English, French, Spanish, and Chinese. It provides students with basic inline suggestions as they write, based on a dictionary and a fixed set of grammar rules. It is intentionally not AI-based and will not rewrite student work.
Spell check highlights misspellings, capitalization errors, and common typos, and suggests quick fixes.
Grammar check highlights common issues such as verb agreement, run-on sentences, and punctuation mistakes.
You can enable this when setting up your assignments.
Note: Spelling and Grammar settings are only available when students work in the TrueMark editor. In Google Docs assignments, TrueMark disables Grammarly, but students may still have access to Google Docs spelling and grammar tools and Mac Writing Tools.
Spelling and grammar check outside of TrueMark
TrueMark automatically disables the Grammarly Chrome extension and any browser-based spelling or grammar check.
This ensures that students only have access to spelling and grammar check if you enable it for the assignment.
Spell-check support across assignment types
Writing environment | Grammarly | Basic Spell/grammar check | Device Writing Tools (For example, Mac) |
TrueMark Editor + Lockdown Mode | Disabled | Disabled by default (Managed by TrueMark settings) | Disabled |
TrueMark Editor (without Lockdown Mode) | Disabled | Disabled by default (Managed by TrueMark settings) | Available |
Google Docs | Disabled | Available through Google Docs | Available |
Other tools that rewrite work for students.
Some browser extensions also include more advanced AI writing features that can rewrite phrases or entire sentences. TrueMark proactively disables Grammarly, and as an additional safeguard, TrueMark also flags other inappropriate use of external writing tools for your review.
Specifically, TrueMark will flag if a student inserts 10 or more words using an external extension (e.g., translation tools, AI writing assistants, etc.). This suggests the student is using a browser tool to generate or modify text. This could be a grammar checker (benign) or an AI writing tool (potentially concerning depending on your policies).
