MinishLab/semhash 💎 hidden gem
Fast semantic deduplication of text datasets — strips near-duplicate chat turns before topic modelling so clusters come out clean.
segment-any-text/wtpsplit 💎 hidden gem
Splits text into real sentences in 85 languages using small CPU models, including text with no punctuation.
vibrantlabsai/ragas
Scores how good a retrieval-based AI answer is, so a change to Grasppy can be shown to have helped or hurt.
pemistahl/lingua-py 💎 hidden gem
Knowing which language a paragraph is in — before you spend a model call finding out.
cheshire-cat-ai/core 💎 hidden gem
The opposite architecture from the LiteLLM-plus-custom-code path — batteries actually included: FastAPI, RAG, plugin loader, WebSocket chat, all in one image.
MinishLab/vicinity 💎 hidden gem
One interface over several nearest-neighbour backends — the throwaway in-memory index for a single conversation.
shap/shap
Per-prediction feature attribution — which of tsfresh's 700 features the surviving model actually leans on, and whether that reason is embarrassing.
optuna/optuna
Hyperparameter search that samples the promising regions and prunes hopeless trials early — a week of sweeps back as an afternoon.
HKUDS/LightRAG
Entity-and-relationship graph over documents with local and global query modes — GraphRAG's structure at a fraction of the cost, stored in PostgreSQL.
TutteInstitute/datamapplot 💎 hidden gem
Labelled data maps with proper label placement — a diagnostic for cluster naming and a shareable marketing image.
TutteInstitute/toponymy 💎 hidden gem
Names clusters at every level of a hierarchy using sub-cluster structure and sample documents rather than a bag of keywords.
apple/embedding-atlas
Apple's interactive embedding map with automatic cluster labelling — recommended as a design study for Grasppy's overview screen, not as a dependency.
LibreTranslate/LibreTranslate
Self-hosted machine-translation API — removes the per-character meter from running a bilingual site.
x-tabdeveloping/turftopic 💎 hidden gem
Five families of topic model behind one scikit-learn-style API — the head-to-head against BERTopic in one afternoon.
MaartenGr/BERTopic
The standard way to turn a long thread into named subtopics with a parent/child hierarchy and a timeline view.
feyninc/chonkie
Focused text-chunking library — semantic and recursive splitters that respect message boundaries, so subtopics come out clean.
microsoft/graphrag
Builds a knowledge graph from text, clusters it into nested communities, writes a summary for each level.
MinishLab/model2vec 💎 hidden gem
Distills sentence-transformers into static embeddings ~15x smaller and hundreds of times faster on plain CPU.
