Vibe Reading Manga

Comment

Inspiration

We like manga like Jujutsu Kaisen and Chainsaw Man, but it sucks that even the most popular series can take years to get an anime adaptation. Most manga never get one at all, leaving millions of readers stuck with static pages or low-quality fan edits, even though the stories deserve to feel alive. We wanted a way to experience manga while reading it, not years later.

What it does

Manga.ai turns any manga or graphic novel into an animated reading experience. As you scroll through a page, subtle animations bring the art to life eye blinks, hair movement, aura pulses, smoke, rain, impact shakes, and depth effects while preserving the original artwork and pacing. It’s “vibe reading” manga.

How we built it (Gemini Integration)

Manga.ai uses Gemini 3 for prompt intelligence and Veo 3.1 on Vertex AI for video generation. Each PDF page is rendered to a high‑resolution image. Gemini 3 (prompt + analysis models) inspects the page and builds a constrained motion‑only prompt that preserves line art and composition. That prompt, along with the original frame, is sent to Veo 3.1 (Vertex) to generate a short image‑to‑video clip that starts exactly on the source frame. The backend manages queueing, caching, and rate limits; the frontend streams the generated clips as you scroll.

Challenges we ran into

  • Prompt control vs. art preservation: getting motion without “redrawing” the artist
  • Keeping text bubbles readable under motion constraints
  • Accidentally spending $100 on Google Console by switching from free trial to paid mode (not paying attention to usage)

Accomplishments that we're proud of

  • Turning static manga pages into smooth, scroll-based animated scenes
  • Using Gemini video generation in a way that feels practical, not gimmicky
  • Proving that manga animation doesn’t need a full studio or years of production

What we learned

HOW GREAT GEMINI IS!!!

What's next for Manga.ai

  • Collaborative reading: send a page animation to friends and comment
  • Firebase accounts + cloud sync so readers can upload manga, save progress, and resume anywhere
  • Personal libraries with history, bookmarks, and continue‑reading
  • Shareable animated clips/links for panels and pages
  • Smarter panel‑aware motion and genre‑specific presets
