Sassbook

While Sassbook's AI Story Writer (especially for genres like Sci-Fi) is excellent for generating story ideas and initial scenes, it's best suited for shorter stories or chapter outlines due to character limits and generation constraints. You can use it for multiple chapters, but you'll need to generate each chapter separately and then combine them, keeping an eye on your overall character usage.

The free plan has strict limitations on both character count per generation and the total number of generations per month. While the exact numbers aren't specified, expect them to be significantly lower than the paid tiers. All features are available, but your usage will be severely limited until you upgrade to a Standard or Premium plan.

API access is included in both the Standard and Premium plans. Sassbook provides developer API documentation with examples to help you integrate its AI capabilities into your application. Check the API documentation section of the website (usually linked in the footer) for specific code samples and instructions.

Sassbook's abstractive summarization aims to create human-like summaries by understanding the context and generating new sentences, rather than just extracting existing ones. While it may sometimes include elements of extractive summarization, the goal is to produce a condensed version that captures the essence of the original text in a new, coherent way. This is different from purely extractive summarization, which only pulls out key sentences.
