Frequently Asked Questions about Thinking Line

Can I use Thinking Line videos commercially if I'm on the free plan?

No. Commercial usage rights come only with the Pro plan at $29/month. The free tier (4 videos/month) does not include commercial rights, and those videos carry a watermark. If you need to license explainer videos for client work or business use, you will need Pro.

What animated chart types does Thinking Line generate automatically?

Thinking Line natively animates bar charts, pie charts, graphs, and cycles, these draw themselves as part of the video without manual creation. The tool builds multi-scene explainer videos where these elements integrate with hand-drawn animation and narration, so you do not have to choreograph each chart separately.

Does Thinking Line offer voice cloning for narration?

Voice cloning is available on the Pro plan ($29/month), which provides access to premium AI voices in addition to a standard voice library. The free tier uses standard voices only. If you need a personalized voice for your explainer videos, you will need Pro.

What is the export quality on each pricing tier?

Free and Pro tiers differ in resolution and watermarking. The free plan exports at 720p with a watermark and produces 4 videos per month. The Pro plan ($29/month) exports at 4K quality without a watermark and allows 30 videos per month. Enterprise customers can negotiate custom arrangements.
