TWO WAYS TO MAKE AN IMPACT

Made for the stories you want to tell.

A cliffhanger they can’t leave. A product they can’t overlook. One studio, from the first idea to the final cut.

AI short drama creation

Give them a reason to watch the next episode.

Bring a novel, a screenplay, or just the premise. Shape it into episodes, build your cast, and direct the moments that make a story yours.

  • Plan episodes from your story or script
  • Reuse character and scene references across shots
  • Review the storyboard before generating video
Create your story

AI video ad creation

Make your product the main character.

Start with a product, an offer, and an audience. Build a visual story around what makes it worth choosing, then refine the hook, shots, and cut.

  • Bring product images and a creative brief
  • Guide visual identity with product references
  • Create portrait or landscape campaigns

What is Katechon Arc?

Katechon Arc is an AI video creation studio for short dramas, narrative videos, and video ads. It connects script planning, character and product references, storyboards, video generation, voiceover, and film export in one workspace, guided by an AI agent.

Do I need a finished script or editing experience?

You can start with an idea, a novel, a script, or product materials. The agent helps you develop the production step by step. You can review and change the script, references, and storyboard before generating video.

Can I create product ads as well as short dramas?

Yes. Drama projects develop stories into scenes and episodes. Ad projects start with a creative brief and product assets. Both use the same production workflow for visual references, storyboards, generated clips, and a final film.

How do characters and products stay consistent?

Arc reuses visual references for characters, scenes, props, and products throughout the workflow. This gives generated shots a shared foundation. AI results can still vary; review the outputs and regenerate individual shots when needed.

How do subscription credits work?

Each plan provides a monthly credit allowance. Credits cover model usage across the creative workflow, and the amount used depends on the model and generation settings. Annual plans release credits each month. Unused plan credits expire at the end of that monthly window; purchased top-up credits never expire.

How much does it cost to make a video?

There is no fixed credit cost per finished film. The model, number of shots, clip duration, resolution, voiceover, and revisions all affect usage. Check the estimates and your credit balance in the studio before generating. Plan allowances are a creative budget, not a guaranteed number of videos.

Can I cancel my subscription?

You can manage your subscription in the billing portal from your account. Cancellation stops future renewals; paid credit windows retain their original expiry dates. Review the billing portal for the effective date and any plan-change charges before confirming.

What can I export?

Download your assembled film or export a Jianying draft to continue editing. Projects can use portrait or landscape formats, depending on the selected model and settings. CapCut compatibility has not been verified.

Can my team work on a project together?

Yes. The Organization plan includes five members, including the owner, and 42,000 monthly credits shared by organization-funded projects. Personal projects can also invite collaborators; in those projects, each collaborator uses their own credits.

Does it work on mobile and desktop?

The studio runs in your browser on mobile and desktop. Start ideas and review your projects on a phone; a larger screen gives you more room for detailed storyboard and production work.
