Whiteboard explainer videos, on demand
Turn any idea into a whiteboard explainer
Give Rekiva a prompt, a note or a document. It writes the lesson, draws every scene line by line, and narrates it end to end — one short video, ready to watch.

How it works
From sentence to storyboard
Say what to explain
Type a prompt, paste a note, or point at a document. One sentence is enough.
Rekiva writes the lesson
It plans a teaching storyboard: a hook, one running example, and the beats that carry it.
It draws, stroke by stroke
Each beat becomes a frame; a local engine traces every line and fills it while the sentence is spoken.
One narrator, in sync
A single voice reads the whole lesson, and each icon appears exactly when it is named.
Where people start
One idea, wherever it needs to land
Training & onboarding
Turn SOPs and policies into short explainers new hires actually finish.
Education
Notes and lessons become narrated visuals students can replay.
Product walkthroughs
Show a feature or a setup flow without booking a call.
Creators
A script or an idea becomes a channel-ready explainer.
Small business
FAQs and how-tos without hiring a studio.
Developers
Drive it from your own pipeline and get the finished MP4 back.
Why it works
An explainer, not a slideshow with a voiceover
Understandable
Paced to teach
Scene by scene, drawn while narrated — not a wall of text with a voiceover.
Fast
A minute in a minute
A one-minute explainer is generated in roughly the time it takes to watch it.
Priced to use
One credit ≈ one second
Simple credit pricing so daily lessons and one-off demos both make sense.
Pricing
Credits that scale with use
One credit is roughly one second of finished video.
Business
Branding, a custom voice and higher limits. Long lessons and team seats.
FAQ
Questions, answered
- What can I feed Rekiva?
- A prompt, a paragraph of notes, or a plain-text document. It reads the source and turns it into a narrated whiteboard explainer — no timeline, no keyframes.
- How long can a video be?
- Short explainers work best today, and a single run is built scene by scene. Longer lessons are on the roadmap as multi-sheet runs.
- How are credits counted?
- Roughly one credit per second of finished video. Every new account starts with 20 free credits, and unused credits from a failed run are refunded automatically.
- Who narrates it?
- Google Gemini speaks the whole lesson in one take so the voice never drifts; if Gemini TTS is unavailable, ElevenLabs picks it up automatically.
- Is my source kept private?
- The engine runs in a private worker with no public endpoint. Only the finished MP4 is kept — intermediate frames, audio and plans are deleted after each run.
