Code Explainer Shorts Maker

Turn a programming concept into a 9:16 Short built from real, syntax-highlighted code cards — not a cropped screen recording. Every scene stays editable until the moment you publish.

How it works

From concept to published Short

Four steps, one studio — no exporting between tools.

1
ScriptGive it a concept — closures, database indexes, async/await. The AI writes a Short-length script grounded in your channel and knowledge base, and you edit it line by line like a doc.
2
ScenesEach script line becomes a scene: a syntax-highlighted code card, a diagram, a terminal. Swap the snippet, rename a variable, reorder lines — nothing is baked pixels.
3
NarrationPick from 24+ voices with in-app previews and every scene syncs to the read automatically — or record your own take with the built-in screen and camera recorder.
4
PublishOne click to YouTube with an AI title, description, and auto thumbnail. Schedule it for when your audience is actually watching.
Included

What you get

Built for explaining code on a phone screen, end to end.

Code cards built for phones

Syntax-highlighted snippets sized for a 9:16 screen, so a for-loop is legible at arm's length — no squinting at a full-width IDE crammed into a vertical frame.

100+ motion components

Terminals, diagrams, bar and line charts, PR cards, timelines. Compose an explainer from parts, layer them, and reuse the structure on your next Short.

Fix code without re-recording

Spot a typo in a snippet after the voiceover exists? Edit the card and re-render. Scenes are layered objects you can reopen anytime, not exported frames.

Word-level cleanup

Recorded narration is transcribed by a local Whisper model with word timestamps — trim by word, auto-detect filler words, and remove silences from the transcript.

Your keys, zero markup

Bring your own Gemini, OpenAI, or ElevenLabs keys, stored encrypted. You pay the providers directly — no credits system, no markup on top.

No watermarks, ever

The founding-creator pilot is free, needs no credit card, and never stamps a logo on your video.

FAQ

Common questions

Do I need to record my screen?

No. Code is rendered as motion components — you paste or type the snippet and the studio animates it as a scene. If you prefer a live take, a built-in screen and camera recorder is there too.

Can I change the code after the scenes are generated?

Yes. Scenes are layered, editable objects — text, code, colors, and timing stay adjustable. Edit the snippet and re-render; you never start over.

How does narration stay in sync when I edit a scene?

Voice-sync is automatic: each scene's duration follows its narration. Change the script line, regenerate the read, and the scene timing follows.

What does a code explainer Short cost to make?

ReelMint is free during the pilot. Generation runs on your own API keys, billed by the provider with zero markup — there is no credits system.

Can I make explainers in languages other than English?

Yes — 8+ languages including Hindi, Spanish, French, German, Portuguese, Japanese, and Arabic, plus code-switched Hinglish with clean romanized captions.

Can an AI agent make these for me?

Yes. ReelMint ships an MCP server, so Claude Desktop, Claude Code, or Cursor can drive the whole pipeline — script, scenes, render, publish — under your review.
