Most AI tools for teachers require you to open a new app, paste your content, wait for output, then copy it back. Brisk skips all of that. It lives inside the tools you already use.

How It Works

Install the Chrome extension. That’s it. Brisk now appears as a sidebar in Google Docs, Google Slides, YouTube, and other web-based tools. You highlight text, click a Brisk action, and get results without leaving the page.

No new login. No new app. No copy-pasting between tabs.

What It Does

Inside Google Docs

• Give feedback — Highlight student writing, click “Give Feedback,” select your rubric criteria. Get specific, constructive feedback in seconds.
• Change reading level — Highlight any text, adjust to a different grade level. The adapted text replaces the selection or appears in the sidebar.
• Create quiz — Highlight a passage, generate comprehension questions instantly.
• Translate — Highlight text, translate to any language while keeping the formatting.

Inside Google Slides

• Generate speaker notes — Click on a slide, Brisk writes presenter notes based on the slide content.
• Create slides from text — Paste an outline, Brisk generates a full slide deck.

Inside YouTube

• Summarize video — Open any YouTube video, Brisk summarizes the content and generates discussion questions.
• Create worksheet — Generate a worksheet based on the video content, with comprehension questions and vocabulary.

What Impressed Me

Zero friction

This is Brisk’s killer feature. You don’t change your workflow at all. You’re already in Google Docs grading essays — Brisk just adds a button. The cognitive cost of using it is nearly zero.

Feedback quality

The rubric-aligned feedback is genuinely useful. It doesn’t just say “good job” or “needs improvement.” It identifies specific sentences, explains what’s working, and suggests concrete revisions. Better feedback than I’d write at 9 PM on a Sunday.

Speed

Feedback on a student essay: 3-5 seconds. Reading level adaptation: 5 seconds. Quiz generation: 5 seconds. Everything feels instant.

What Frustrated Me

Limited outside Google Workspace

If your school uses Microsoft 365 instead of Google Workspace, Brisk is mostly useless. It’s deeply tied to Google’s ecosystem. There’s no Word or PowerPoint integration.

Feedback can be generic on short pieces

For longer essays (3+ paragraphs), the feedback is excellent. For short responses (1-2 sentences), it sometimes gives feedback that’s longer than the student’s writing. Not always helpful.

No offline mode

It’s a Chrome extension that needs internet. If your school’s WiFi goes down (and it will), Brisk goes with it.

The Verdict

Brisk is the AI tool I recommend to every teacher who says “I don’t have time to learn a new tool.” You don’t have to learn anything. Install it, and it’s just there — making your existing workflow faster.

Price: Free. Setup time: 30 seconds (install extension, done). Time saved: 30-60 minutes per day if you grade or adapt materials regularly. Rating: 8.5/10 — The best “invisible” AI tool for teachers. You forget it’s AI — it just helps.
