PromptPerfect alternative for developers
PromptPerfect (Jina AI) is winding down — new signups closed in June 2026 and the service goes offline on 1 September 2026, with data deleted shortly after. If you were using it to sharpen coding prompts, PromptStock covers that specific job: turning a rough request into a structured prompt aimed at the tool you actually code in.
| PromptStock | PromptPerfect | |
|---|---|---|
| Status | Active | Shutting down 1 Sept 2026 |
| Focus | Coding prompts specifically | General-purpose prompt optimisation |
| Target-tool awareness | Claude Code, Cursor, Copilot, ChatGPT | Generic output |
| Free tier | 2/day, no card | Discontinued |
| Export your history | Searchable, copyable | Data deleted after shutdown |
Honest verdict
If you mainly used PromptPerfect for code, PromptStock is a direct replacement — a free account takes an email address and no card. If you used it for marketing or image prompts, it isn't — PromptStock deliberately only does coding prompts well.
Try it on the next prompt you were about to write.
Free account, no card. If it doesn't obviously beat what you typed, close the tab.
