40,000+ creators using AI to highlight captions automatically
Auto Highlight Keywords is an AI-powered feature that automatically detects and highlights the most important words in your video captions. Instead of manually selecting which words matter, the AI analyzes your script and identifies the hooks, punchlines, key information, and calls-to-action that deserve visual emphasis.
One simple toggle activates automatic highlighting across your entire video. The AI understands context and intent, not just keywords. Your viewers' eyes are guided to exactly where they need to focus, making every word count and every message land harder.
Highlighted captions drive 138% more engagement. When key words pop visually, viewers retain information better, stay engaged longer, and are more likely to take action. Auto Highlight Keywords transforms passive text into active visual storytelling.
Customize everything: change highlight colors to match your brand, adjust opacity, choose bold or italic emphasis, and control which word types get highlighted. The AI handles the detection—you control the style.
Most creators publish captions without any emphasis. Plain text is boring. Your viewers scan rather than read, missing the most important parts of your message. This drives higher dropout rates, lower completion percentages, and less engagement overall.
Manual highlighting requires clicking on individual words and changing colors for every single caption. For a 5-minute video with 50+ captions, that's 100+ clicks and color changes. You're manually deciding which words matter when you should be focusing on storytelling. This takes 30-60 minutes per video.
Even worse, you often miss the most impactful moments. You highlight the obvious keywords but miss the emotional hooks and subtle punchlines that actually drive engagement. Your highlighting becomes inconsistent and ineffective.
Auto Highlight Keywords solves this by using AI to identify what matters and automatically emphasize it. One toggle handles it all.
Step 1: Upload Your Video — Load your video with captions (auto-generated or custom) into the editor.
Step 2: Toggle Auto Highlight — Click the "Auto Highlight" toggle. The AI instantly scans your captions and identifies the most important words.
Step 3: AI Analyzes & Emphasizes — The system detects hooks, key information, emotional words, questions, and calls-to-action. All important words are automatically highlighted.
Step 4: Customize Colors & Style — Choose your highlight color to match your brand. Adjust opacity, font weight, and emphasis style (bold, italic, underline, background color).
Step 5: Review & Fine-Tune — Preview how your highlighted captions look. Manually adjust any highlights if needed, or let AI handle it completely.
