Possible disadvantages of Vellum

  • Mac-Only Software
    Vellum is only available for macOS, which limits access for authors who use Windows or other operating systems.
  • High Cost
    The one-time purchase cost of Vellum can be high for independent authors, especially for those who only plan to publish a few books.
  • Limited Editing Tools
    Vellum is primarily a formatting tool and offers limited text editing capabilities, which means users may need other software for comprehensive editing.
  • No Built-in Distribution
    While Vellum facilitates the creation of ebooks, it does not provide built-in distribution or publishing services, requiring authors to handle this separately.
  • Internet Activation Required
    Users need to have an internet connection for software activation and certain updates, which might be inconvenient if connectivity is an issue.

Langtail features and specs

  • LLM evaluation
    Evaluate your LLM-based apps easily with deterministic functions or an LLM as a judge.
