AI tools to make & edit video
These tools help you turn raw footage, scripts, product shots and recordings into clips people can watch and share. Common jobs include trimming interviews, adding subtitles, making short social posts and creating presenter-led explainers. The best AI video editor for social media is usually the one that delivers a publishable short clip quickly while leaving room to fix captions, sound and framing.

How they differ
Runway is the more flexible choice when you need cloud video generation and editing in one place, while PixVerse is built around fast social clips. Both may need reruns or cleanup: PixVerse can leave artifacts and need audio fixes, while Runway is not the right fit for studio photorealism or precise lip sync.
CapCut is a practical choice for short-form editing with a usable free option. VEED.IO puts browser editing, captions and voiceovers first. Choose HeyGen for a talking-head or translated video, not cinematic closeups or long training material that must remain frame-perfect.
Before you pay
- Export a real test clip first. The best AI tool to add captions to videos is the one that gives you usable subtitle timing on your own footage.
- Check watermark and export rules, including resolution, download formats and any limits that affect finished client work.
- Read the commercial-use terms for generated video, voices, music and stock assets before publishing anything for a client or product.
