Nible — AI explainer video generator: whiteboard videos from a prompt

Q: How do the plans work?

Free gives you 240 credits, enough for three 40-second videos. Pro is $19 a month for 5,000 credits and Max is $40 for 13,000; a video costs credits by its length and credits refill each month. Business adds your logo, your voice and an API, priced on volume.

How it works

There is nothing to learn. You describe, Nible makes, you ask for changes.

Describe the video

"How a jet engine works." "Why the sky is blue." An exam question with its answer. Pick a length from 40 seconds to 3 minutes and a voice.

LENGTH Medium · 2 minVOICE Male

Nible writes, draws, speaks

A short lecture with concrete facts. A drawing of every object it names, painted for this video if the library has none. A narrator timed to the words.

A frame from the mRNA vaccine video: ribosome, spike protein, cell

Within days, the mRNA strand degrades in the cell.

Ask for changes

"More technical." "Shorter." "Add the dates." Reply under the video and get a revised one in the same thread, with the earlier version kept.

01 · The problem: virus invades

A virus arrives with spike proteins on its surface. These spikes let it grip your cells and infect them. Your immune system must learn to recognize spikes.

06 · Vaccine versus real virus

Without the vaccine, your body sees the spike for the first time during real infection. With the vaccine, your antibodies are ready before the virus arrives.

07 · The mRNA is broken down

Within days, the mRNA strand degrades in the cell. It never enters your DNA or changes your genes. Only the antibodies remain, watching for the spike protein.

The script sits under every video. Read it before you publish.

Drawing: white blood cell — white blood cell

Painted for the topic, then kept, so the next video on it starts faster.

Questions

How long does a video take?

Usually one to two minutes from the moment you press enter; a little longer when a topic needs new drawings.

Are the facts right?

Nible sticks to textbook-level facts and names its numbers. Read the script under the video; if something is off, reply and ask for the correction.

Can I use the videos commercially?

Yes. What you make is yours to publish, teach with or sell.

What languages and formats?

English, 16:9 MP4 with an SRT subtitle file. Other languages and vertical video are on the way.

How do the plans work?

Videos are paid for in credits, and the price depends on length: 80 credits for 40 seconds, 110 for one minute, 140 for two, 180 for three. Free gives you 240 credits once, Pro 5,000 a month, Max 13,000. A video that fails is refunded. Credits reset on the first of each month and do not carry over. Business adds your logo, your voice and an API, priced on volume.

Is there an API or a team plan?

Yes, on the Business plan. Write to us on the contact page with what you want to make and roughly how many a month.

Is Nible an AI video generator?

Yes. Nible uses AI to write the script, paint a picture for every object it names, and record the narration, then assembles a whiteboard explainer video with subtitles. You keep control: the script is shown under the video and you can ask for changes in plain words.

Can I turn my notes or a question into a video?

Yes. Paste a paragraph of notes, a lesson outline or an exam question with its answer into the prompt. Nible turns it into a narrated explainer; the more concrete the facts you give, the closer it sticks to them.

What if a video fails?

It doesn't count against your plan. Press "Try again" or reword the topic.

About Nible

Nible is an AI explainer video generator. It turns a prompt, a page of lesson notes or an exam question into a whiteboard explainer video: a narrated, subtitled 1080p MP4 with pictures drawn for the topic, made in about a minute. Teachers use it to turn notes into lessons, trainers to turn procedures into onboarding videos, creators to turn ideas into YouTube explainers, and businesses to answer how-to questions on video instead of in text. Videos are landscape 16:9 in English today; every video you make is yours to publish, teach with or sell. Nible is built by its founder, Nickesh Paudel.
