●●SolidBig BrainWizardryBold Bet

Number theory instead of learned routers, but conjecture-level math and limited production evidence.

Strengths

•Genuinely novel approach: trades learned routing (FAISS, HNSW) for deterministic GCD-based partitioning—mathematically elegant.
•Includes benchmark suite (Tau vs brute-force, FAISS, HNSW) with multiple backends (NumPy, PyTorch, MLX) for real comparison.
•Open about limitations: explicitly flags conjecture status; doesn't oversell unproven math as settled theory.

Weaknesses

•Mathematical foundation is explicitly conjectural—routing claims unproven; production viability unclear until formal proofs exist.
•No published benchmarks or real-world deployment evidence; unclear if speed gains offset implementation overhead vs HNSW.

Threadlink – Turn long AI chats into portable context cards

The product nails a painful micro-problem: turning sprawling chat logs into bite-sized, copyable context cards with explicit controls (Light/Balanced/Aggressive compression, token counts, BYOK for privacy). It’s a useful MVP — the UI signals care and control — but without obvious integrations or export targets (ChatGPT plugin, Slack, or API) it risks staying a handy one-off rather than a daily workflow tool.
