AIQualityHQ
Free, browser-native AI prompt quality checker, rewriter, and security scanner running 100% locally.
AIQualityHQ is a free, browser-native toolkit for AI developers, QA teams, and prompt engineers. It allows users to score prompts across 6 core dimensions, refactor raw instructions for specific LLMs, optimize token costs, and scan for prompt injection and jailbreak threats using a deterministic engine that runs entirely client-side for complete privacy and instant execution.
Perplexity
Answers with the sources attached
Perplexity answers a question and shows which pages it read, which is the difference that matters when the answer is going into a video and somebody in the comments will check it. Research runs are the format creators use most: ask about a niche, get a written brief with citations rather than ten tabs to read yourself. Pro raises the limits and adds credits for the agentic Computer feature. The free tier is enough to judge whether the citation habit suits how you work.
Our note
Worth having open beside whichever assistant you write with rather than instead of it. The value here is the source list, and the moment you stop clicking through to the sources you are paying for a slower chatbot.
