PromptPerfect – Open-source prompt optimizer for LLMs
Handy prompt refiner, but prompt engineering itself is becoming obsolete with better base models.

Local prompt optimization framework for any Windows app, but learning mode lacks substance.
Windows users who want better AI outputs without subscriptions
Prompt engineering tools · Grammar checkers with templates
The problem: most people get bad AI outputs because their prompts are vague. AuraText transforms raw prompts using frameworks like RISEN, COSTAR, and RTF – same AI, better input, dramatically better output.
Key things it does: - Works as a floating overlay in any Windows app - Built-in AI router (Claude for analysis, GPT-4 for creative, Gemini for research) - Bring your own API keys – no subscription - Supports 11 providers including local Ollama - Learning Mode to actually build prompt skills over time
Built this solo in 4 months. 1,000+ downloads so far. Completely free during beta.
