Rekka AI
Create narrated hand-drawn videos from a topic, document, or prompt for onboarding, training, product explainers, and lessons.

Rekka creates narrated, hand-drawn explainer videos from a topic line or a detailed prompt. It is designed for people who need to explain a concept, process, or piece of source material clearly without building slides, recording themselves, or editing a video timeline.
The platform turns a topic or source document into a finished MP4 with narration and synchronized drawn visuals. It can be used through the web app, API, or MCP, making it suitable for everything from a one-off explainer to automated video generation inside an existing product or agent workflow.
Key Features
AI Explainer Video Generation
Start with a topic or fuller prompt and Rekka generates a narrated explainer video.
The output combines:
- Narration
- Hand-drawn visuals
- Synchronized scenes
- Structured explanations
This removes the need to manually create slides, record a voiceover, or assemble the result on a video timeline.
Multiple Ways to Generate
Rekka supports different workflows depending on how you want to use the platform.
Web app: Enter a topic directly in the browser and generate a video without setup.
API: Use a REST call to integrate video generation into your own application or workflow.
MCP tool: Allow AI agents to call Rekka during a conversation and generate an explainer as part of an agent-driven workflow.
Document & Source Material Input
Rekka can work from source material rather than requiring you to describe everything manually.
You can attach:
- Images
- PDFs
The generated video can then explain the supplied material, making it useful for documentation, training resources, and educational content.
Four Visual Styles
Choose from four hand-drawn visual formats:
- Whiteboard
- Chalkboard
- Crayon
- Retro reel
The different styles change the visual presentation while using the same underlying topic-to-explainer workflow.
Retro Reel for Vertical Content
The Retro reel format is designed for 9:16 video.
It uses one shot per line and includes captions directly in the frame, making it particularly suited to feed-first content where vertical viewing and readable captions matter.
Multi-Chapter Videos
Rekka can turn a single prompt into a longer, multi-chapter explainer.
This makes it suitable for topics that need more structure and depth rather than being limited to short-form clips.
Server-Side Rendering
Videos are rendered on the server, so you do not need to remain on the page while generation finishes.
Once the video is ready, you can:
- Watch it in the app
- Download the MP4
- Share it through a public link
Built For Educators, Teams & Content Creators
Rekka is designed for people who need to explain information clearly without taking on the full production process.
It can be useful for:
- Product teams
- Training teams
- Educators
- Course creators
- Sales teams
- Internal operations teams
- Documentation teams
- Developers building video generation into products
Common Use Cases
Onboarding: Explain products, processes, or workflows to new employees and customers.
Training: Turn internal processes and instructional material into narrated visual explainers.
Product documentation: Convert technical or product information into easier-to-follow videos.
Internal walkthroughs: Explain company processes without requiring someone to record a presentation.
Classroom material: Turn educational topics and source documents into narrated lessons.
Sales pages: Use concise explainers to communicate how a product or process works.
Feed-first content: Use the vertical Retro reel format for short-form, captioned content.
From Topic to Finished Explainer
Traditional explainer videos can require scripting, slide creation, voice recording, illustration, animation, and timeline editing. Rekka combines those steps into a topic-driven generation workflow.
You provide the subject, and the platform creates the narration and synchronized drawn visuals. For source-based videos, you can also attach an image or PDF so the explanation is grounded in the material you want to communicate.
Flexible for Different Workflows
Rekka can be used as a simple web application when you need a single video, but it can also fit into automated workflows through its API and MCP tool.
The API allows developers to integrate video generation into their own products, while MCP gives agents a way to request video generation during a conversation. This makes the same explainer engine usable for both manual content creation and programmatic workflows.
Why It Matters
Explaining a process clearly often takes more production work than writing the explanation itself. Slides need to be designed, narration needs to be recorded, visuals need to be created, and everything needs to be synchronized.
Rekka packages those steps into a single workflow for narrated, hand-drawn explainers. With document input, multiple visual styles, multi-chapter generation, server-side rendering, API access, and MCP support, it provides a practical way to turn information into finished educational and instructional video without traditional editing work.
Turn Topics Into Narrated Explainers With Rekka
Create finished explainer videos from a topic, prompt, image, or PDF with narration, synchronized hand-drawn visuals, multiple styles, multi-chapter support, and flexible web, API, and MCP workflows. Rekka gives teams and creators a simple way to turn complex information into visual explanations without building slides or editing a timeline.
