GPT-4 makes thin wrappers fragile
Verdict history

Correction: Killed → Under Attack
Correction: the original Killed verdict was wrong. PromptBase's marketplace remained active and added Select in February 2026; Writesonic also remained in operation. This refutes the named-product death claim, but does not prove the category is safe or that GPT-4 caused the pressure.

Threat
Products built as light prompt wrappers lose differentiation when a stronger base model improves every generic workflow.
What Changed
Better general reasoning lets one model cover many product categories that previously looked separate.
This historical wave explains why model improvements can erase whole classes of thin apps without any single platform integration.
Categories Hit
- Prompt wrapper SaaS: If the product is mostly a prompt preset, better general models can absorb the value quickly.
Brands / Services Hit
- AI prompt marketplaces (promptbase.com)
- Writesonic (writesonic.com)
