Narrated animations in your browser

Studio makes narrated math animations on our servers, paid with credits from a Trial pack or a Monthly or Yearly plan.

Web generation

Make a narrated math animation in your browser, without installing anything.

  • Describe an idea or upload a readable PDF, PPTX, Markdown or text file in Studio. LemmaReel plans, animates and narrates it on our servers.
  • Videos run up to 5 minutes, as 1080p MP4 with English narration and no watermark.
  • Revise a finished video with a short note; each revision is kept as a new version in Studio.
  • Web generation runs on credits: a one-time Trial pack ($5, 100 credits that never expire), or a Monthly ($15) or Yearly ($150) plan with 1,000 credits each month. 10 credits = 1 minute of video, rounded up per video.
  • Credits are held when a video starts, charged only when it succeeds, and released if it fails or you cancel.
  • Your uploads and videos are stored privately in your account. See Privacy for how your brief is processed.

The Mac CLI remains a separate one-time purchase with no length limit. See Pricing for current plans.

0.1.0a3

One license, one active computer

The CLI command becomes lemmareel, and each license activates one computer with online authorization.

LemmaReel 0.1.0a3

Each license now activates one computer, and the command is lemmareel.

  • Your $49 purchase covers one active computer. Repeat downloads, updates and reinstalls on that computer are allowed.
  • Moving to a new computer: contact support from your purchase email with your order ID. After we verify the purchase, we release the old device.
  • Activation and each preview, render and export check your license online first, with no offline grace period. A job that has already started is not stopped, and your local videos are never deleted.
  • The main command is lemmareel, for example lemmareel doctor. animeweave still works as an alias.
  • Install with the current lemmareel-install.py installer described in Get started. It asks for your license privately, activates the computer and verifies the package hash before installing.

Compatibility and existing installs

Verified on Apple Silicon Macs. Clean-machine installation and Linux are still being validated, and Windows is not supported. Copies of 0.1.0a2 that are already installed are not changed by this release.

0.1.0a2

The local animation toolkit

Early-access CLI with document input, local English narration and MP4 export.

LemmaReel 0.1.0a2

This early-access release included the local CLI, built-in agent guidance, document extraction, English narration and MP4 export.

  • Read text-based PDF, PPTX, Markdown and text files, or start from a topic brief.
  • Generate formula, curve, distribution, comparison and table animations.
  • Check system dependencies with animeweave doctor.
  • Download the current package from your account. Use the installer described in Get started to install a newer release; keep your project files and license before upgrading.

Compatibility

The development workflow has been exercised on an Apple Silicon Mac. Clean-machine installation, Linux and complete Claude Code/Gemini CLI journeys are still being validated. Windows is not supported in this release.

Rendering dependencies and the voice model are separate downloads. Read Get started before installing. Your account’s download card reports the version currently available from the release service.
