Frequently asked questions
What is Planegraph's AI audio?+
Planegraph's AI audio generates voiceovers and sound effects from a text prompt. You write a script, pick a voice, and get natural narration you can sync straight to your video timeline, alongside prompt-generated sound effects.
Is the AI voice generator free?+
Yes. The AI voice and sound effect generator is free to start with no credit card required, and you keep commercial usage rights to the audio you generate. Paid plans add more monthly credits.
Which voices are available?+
Planegraph has custom UGC voices — men and women, in college-age and middle-aged ranges — that sound natural in short-form content, plus a wide range of realistic voices piped from ElevenLabs across accents, ages and tones. You pick the voice per script.
Do you have UGC voices for TikTok?+
Yes. Planegraph includes custom male and female UGC voices in both college-age and middle-aged ranges, tuned to sound natural in TikTok and Reels-style short-form videos — not robotic narration.
Can I use the audio in my videos?+
Yes. Generated voiceovers and sound effects drop straight onto the Planegraph timeline, synced with your video, and export together as a single MP4.
Can I generate sound effects too?+
Yes. Beyond voice, you can generate sound effects from a prompt — whooshes, impacts, ambience and stingers — to layer under your clips.
