CodexLib launches AI content marketplace

The marketplace angle is the real bet here; the codec is the wedge, not the moat. If CodexLib can build a creator flywheel, it could become an agent-native publishing layer, but the compression claim needs much harder proof than a cool symbol table.

• –The public site says roughly 15% savings, and the API sample shows 16.3%, which is far less dramatic than the Reddit pitch's 50-70% claim.
• –The Rosetta decoder is clever because it doubles as format and access layer: free users get previews, Pro users get the full pack content plus decoder support.
• –Symbol substitution only matters if the target tokenizer cooperates, so benchmarked savings by model will matter more than the lore.
• –The strongest long-term moat is the catalog plus creator economics, not the encoding trick alone.
