Frequently asked questions
What is Planegraph's video editor?+
Planegraph's video editor is a multi-track timeline that runs entirely in your browser — no download required. You layer video, images, audio and text tracks, sync them on a timeline, and export finished MP4, with an AI editing agent that can make the edits for you.
Does the video editor have an AI agent?+
Yes. The editor includes a GPT-5-powered editing agent: describe the change in plain text — "cut the dead air, add captions, drop the logo in the corner" — and it performs the multi-step edit on the timeline for you.
Is the online video editor free?+
Yes. The timeline editor is free to use in the browser, and you keep commercial usage rights to what you export. Paid plans add monthly generation credits for AI clips, voices and effects.
Can I add captions, trending audios and greenscreens?+
Yes. The video editor includes captions and text tracks, a library of trending audios you can drop onto the timeline, and popular greenscreen clips you can overlay on your footage.
What formats and resolutions can I export?+
You can export MP4 at 9:16, 1:1 and 16:9 up to 1080×1920, so the same edit is ready for TikTok, Reels, Shorts and YouTube.
Do I need editing experience?+
No. The timeline is designed for quick edits — drag clips, trim, and export. You can also assemble AI-generated clips and voiceovers directly, without separate software.
