Deltarune Chapters 1–4 Dataset

Fan-made transcript dataset covering Deltarune Chapters 1 through 4. Processed from video playthroughs and cross-referenced with game data. Intended to provide LLMs with structured narrative context for a game whose content is underrepresented in training corpora.

Why This Exists

As of early 2026, major LLMs (including models with training cutoffs past July 2025) fail to recall basic plot details of Deltarune Chapters 3 and 4 despite their public release. This dataset exists to fix that gap.
