Product Pillars

What Sets ByThen Apart

  • Single End-to-End Workflow

    Script, voiceover, key visuals, storyboard, video, audio, and editing all happen inside ByThen, for videos up to 30 minutes long. One platform, one subscription, from idea to export.

  • Consistency Across Every Scene

    Every inconsistent scene is a regeneration you have to pay for. ByThen locks your characters, color palette, and art style at the start and holds them across any video.

  • Visuals That Follow Your Narration

    Give ByThen an idea and it writes the script, then builds every scene from what each line says. Name a person, a place, or a moment in your narration, and that’s what shows up on screen. What your viewers hear is exactly what they see.

  • Your Creator Profile, Saved and Ready for Every Project

    Your characters, environments, and visual assets stay saved in your creator profile. Start a new video and everything is already there. No re-uploading. No re-describing.

  • Full Creative Control at Every Stage

    Creative control isn't one decision at the start. Set your visual identity, adjust the script, reshape any scene, replace any clip. Every stage is yours.

How it Works

From idea to published, in five steps

  • 01Creator Setup

    Answer a few questions about your content

    Set your niche, language, format, and the look and voice you want. ByThen locks that identity in, so every video sounds and feels like you.

  • 02Script & Voice

    Start with an idea or script

    Let Content Wizard suggest ideas for your niche and write the script, or bring your own. Pick a narration voice and you're a few clicks from a full production.

  • 03Key Assets

    Build your cast and settings

    ByThen generates the characters and environments your story needs. Refine them to match your idea, then approve once so every scene draws from the same set and nothing drifts.

  • 04Storyboard

    Preview your overall scenes

    Lay out your video scene by scene and adjust the framing and flow. See exactly how it will look before you spend credits generating the full video.

  • 05Video Ready

    Refine it, then publish

    Your full video, up to 30 minutes long, comes back assembled with voice, music, and sound. Trim clips, add captions, drop in your own footage, then export.

ByThenArt

50+ art styles, no prompting needed

From cinematic to anime, monochrome illustration, and claymation, all in a single click. Or upload your own reference and create a style that's entirely yours. Pick your style once, and ByThen holds it across every scene.

Frequently Asked Questions

What is ByThen?

add
ByThen is an AI video producer for long-form content. It lets you generate storytelling videos in a single workflow. The platform includes scriptwriting, key assets, storyboarding, voiceover, video generation, music, and timeline editing. Every project exports directly as an MP4 file.

Who is ByThen built for?

add
ByThen is built for content creators who make structured, narrator-led videos such as faceless YouTube videos, educational explainers, and narrative storytelling. It is especially useful for creators who currently rely on multiple AI tools and want one production workflow instead.

What kinds of videos can I create with ByThen?

add
You can create both short-form and long-form narrative videos from an idea, script, or text source. ByThen supports horizontal (16:9), vertical (9:16), and square (1:1) aspect ratios. This makes your content natively compatible with YouTube Shorts, TikTok, Instagram Reels, and traditional long-form platforms.

How does ByThen turn an idea into a video?

add
ByThen uses a guided, five-step production workflow to turn an idea into a finished video:
  1. Creator Setup: Answer a few questions about your niche, language, format, art style, and voice. ByThen locks that identity in for every video.
  2. Script & Voice: Type a topic and let ByThen write the script, or bring your own, then pick your narration voice.
  3. Key Assets: Generate the characters and environments your story needs. Approve them once and every scene draws from the same set.
  4. Storyboard: Review the video scene by scene and adjust the framing and flow.
  5. Video Ready: Get the full video assembled with voice, music, and sound effects, then trim clips, add captions, drop in your own footage, and export your MP4.

How long can my video be?

add
ByThen generates videos from 30 seconds up to 30 minutes long. Final projects can be edited and exported up to a maximum duration of 60 minutes. All videos export at a locked frame rate of 25 FPS with a fixed 720p resolution (1080p and 4k resolution coming soon).

Can I edit the video before exporting?

add
Yes. ByThen includes a built-in multi-track video editor. You can trim, rearrange, or delete individual clips without regenerating the entire video project. The editor also lets you overlay your own uploaded media, adjust captions, and add sound effects.

Do I need video editing experience to use ByThen?

add
No. ByThen is designed for non-technical creators. The platform replaces complex editing tasks with intuitive style presets, voice libraries, and automated scene generation. You keep creative control without needing traditional production skills.

Is ByThen free to use?

add
ByThen offers a limited Free Plan alongside paid subscriptions. It includes access to script, key asset, and storyboard generation with restricted video durations. This sandbox tier lets you experience the single workflow before upgrading.

Why should I upgrade to a higher Subscription plan?

add
Upgrading to a higher plan gives you more monthly credits at a lower cost per credit. Higher tiers unlock longer video runtime limits, expanded project storage, and premium generation features. If you run out of credits, top-up packages are also cheaper on higher plans.

Can AI Agents use ByThen?

add
Yes. ByThen features a native Model Context Protocol (MCP) server. This allows AI agents like Claude (via Claude Desktop or Claude Code) to seamlessly generate, edit, and orchestrate long-form video content programmatically using natural language. It turns video production into a native capability for your AI workforce.

Is ByThen available on mobile?

add
ByThen is currently built for desktop browsers. Chrome is the primary supported browser, with Edge and Safari also supported. There is no mobile app and no offline mode at this time.

Can ByThen keep characters consistent across scenes?

add
Yes. ByThen locks your characters, environments, color palette, and art style at the start of a project and holds them across every generated scene. This applies to videos from 30 seconds to 30 minutes.

What AI models does ByThen use?

add
ByThen automatically routes each generation to the most suitable model, including Seedance, Kling, and Veo for video, ElevenLabs for voice, and leading language models for scripting. Model selection is handled for you. Manual AI model selection coming soon.

Can the visuals match what my script is saying?

add
Yes. ByThen generates each scene from your script, so the visual on screen and the voiceover always agree.

What content categories is ByThen best for?

add
ByThen is built for faceless, narrator-led video including history, documentary, educational explainers, religious storytelling, and long-form narrative content.

Does ByThen learn my preferences over time?

add
Yes. ByThen learns from the scripts, visuals, and edits you approve, and applies that to future videos. Each project starts closer to your preferred output than the last.
