Advanced Bias Settings & Features
What is Algorithm Bias? These sliders tune the AI's sensitivity. Adjust them if your video has unusual pacing (fast talkers) or tiny visual changes (small handwriting).
Stability Delay 1.5s
Increase if the speaker pauses mid-sentence. Decrease for fast talkers so slides capture quicker.
Similarity Threshold 0.96
Increase to catch tiny additions (like a single written word). Decrease to ignore slight camera movements.

What is SlideX?

An AI-powered lecture slide extractor that turns any video into a clean, searchable PDF — in seconds.

Watching a recorded lecture and manually screenshotting every slide is slow, inconsistent, and error-prone. SlideX automates the entire process: it reads your video frame-by-frame, detects when a slide is fully visible and stable, deduplicates near-identical frames, and compiles only the meaningful slides into a tight PDF or PPTX file. Works with local video files and direct URLs from platforms like YTube, G-Drive, and more.
