AI Tools in CapCut — Complete Guide

Auto Captions is CapCut's speech-to-text AI tool. It listens to the spoken audio in your video and automatically generates synchronized subtitle text without any manual typing. The tool supports multiple languages and places each caption at the correct timestamp automatically.

To use it, tap Text in the editor, then select Auto Captions. Choose your language and tap the generate button. CapCut processes your audio and places subtitle clips in the timeline within seconds. Always review the output — proper nouns, technical terms, and uncommon words sometimes need manual correction. For full styling and customization options, the CapCut subtitles guide covers everything in detail.

Best for: All creators — captions improve reach and accessibility on every platform.

CapCut's AI background removal detects the subject in your video or photo and removes the background automatically — no green screen required. The AI identifies the edges of the subject and masks out everything behind it, leaving the subject on a transparent background that you can place over any other clip or color.

To use it, select a clip in the timeline, tap Cutout in the editing panel, and select Auto Removal. The AI processes the clip and removes the background. For best results, film against a background that contrasts clearly with the subject — a plain wall or solid color works much better than a busy or textured background. The result works well for talking head videos, product overlays, and creative composite shots.

Best for: E-commerce product videos, talking head creators, and composite edits.

Text to Speech converts written text into spoken audio using AI-generated voices. CapCut offers multiple voice styles — different accents, tones, and personalities — that you can apply to any text element in your project. The generated audio is automatically synced to the video timeline.

This tool is widely used for faceless content creation — videos where no on-camera presenter is needed. Instead of recording a voiceover, you type your script, select a voice style, and CapCut generates the narration automatically. It is also useful for quickly adding commentary to clips without setting up a microphone. To use it, add a text element, then look for the Text to Speech option in the text editing panel.

Best for: Faceless content creators, explainer videos, and quick narration without recording equipment.

Motion tracking uses AI to follow a moving subject in your video and attach a text element, sticker, or overlay to it so it moves with the subject throughout the clip. This creates dynamic effects like name tags that follow a person as they walk, labels that stay attached to a moving product, or arrows that point to a specific object as the camera moves.

To use motion tracking in CapCut, add a text or sticker element, then tap the Tracking option in the editing panel. Select the subject you want to track by tapping on it in the preview, and CapCut's AI follows it through the clip automatically. This effect is popular in sports content, tutorial videos, and any content where you want to label or highlight a moving element. Combined with the layer techniques covered in the CapCut layer editing guide, motion tracking opens up advanced composition possibilities.

Best for: Sports content, tutorials, product demos, and dynamic text effects.

Smart Cutout works similarly to background removal but is optimized for still images rather than video clips. It precisely separates the subject from the background of a photo, allowing you to use the subject as a transparent overlay on top of your video. This is useful for adding product images, logos, or character graphics over a video background without any visible background around them.

To use it, add an image as an overlay, tap Cutout, and select Auto Removal or use the manual brush to refine edges. The AI handles the initial detection and you can fine-tune the edges manually if needed. This tool is particularly valuable for e-commerce creators who need to place product images over lifestyle video backgrounds — the workflow is covered in detail in the CapCut e-commerce product videos guide.

Best for: E-commerce sellers, graphic content creators, and anyone combining photos with video.

CapCut's AI video enhancement tool analyzes your footage and automatically improves sharpness, clarity, and overall visual quality. It is particularly effective on footage that was filmed in low light or with an older phone camera. The AI upscales detail and reduces noise without the manual color correction work that would normally be required.

To use it, select a clip in the timeline and look for the Enhance or Smart Enhance option in the editing panel. Apply it and preview the result. The enhancement works best on clips where the original footage has visible noise, softness, or inconsistent exposure. For footage that is already well-lit and sharp, the improvement may be subtle. For manual color correction that gives you full control, the complete CapCut color grading guide covers the full range of manual adjustment tools.

Best for: Creators filming in low light or with older devices who want to improve footage quality quickly.

CapCut's beat detection AI analyzes the rhythm and tempo of your music track and automatically places markers at the beat points in the timeline. You can then snap your clip transitions to these markers for perfectly timed cuts that sync with the music without manually listening and adjusting each cut by ear.

To use it, add a music track to your project, tap the music bar in the timeline, and look for the Beat option. CapCut analyzes the track and places visual markers. From there, trim and position your video clips so transitions land on the markers. This tool works especially well for travel montages, product showcases, and any content set to upbeat music. The Instagram Reels guide and the TikTok tips guide both cover beat sync in the context of social media content.

Best for: Music-driven content, travel videos, product showcases, and highlight reels.
