AIQualityHQ vs Claude Comparison 2026
AIQualityHQ is a free browser toolkit that scores a prompt, rewrites it for a given model and scans it for injection risk. Claude is the assistant you would run that prompt against, free to try and $20 a month. One is a check on the instruction, the other is what the instruction is for.

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.
Only on this side
- Covers research & trends
Claude
A writing and reasoning assistant with a long memory
Claude is an assistant built by Anthropic for work that runs long: a full script rather than a paragraph, a spreadsheet of sponsor replies rather than one email. The free plan covers web search, file creation and memory across conversations. Pro adds more usage, unlimited projects, research and the ability to connect Slack and Google Workspace. The context window is 200k tokens on every plan, which in practice means a long transcript or a stack of documents goes in whole rather than in pieces.
Why people weigh these two
- Claude instead of AIQualityHQ
- Claude will rewrite and critique a prompt in the same conversation you were going to run it in, from $20 with a free tier, at the cost of a repeatable measurement.
- AIQualityHQ instead of Claude
- AIQualityHQ scores prompts and scans them for injection risk, free in the browser, a check on the instruction rather than a partner to write with.
Which one should you pick
AIQualityHQ suits people shipping LLM features: prompt engineers validating instructions, QA engineers checking whether behaviour holds between releases, and developers looking at injection exposure. Everything interactive runs client side and is not metered, and the API tier starts at sixty free requests an hour.
Claude is the model doing the work, with a long memory for drafts and reasoning that runs across a whole document. It will happily critique a prompt in the same conversation you were going to run it in, which is faster and produces no score you can compare against last week's.
Common questions
- Do I need both?
- If prompts are part of a product, yes: one checks the instruction, the other executes it. For occasional writing, Claude alone is enough.
- Is AIQualityHQ metered?
- The browser tools are not metered at all, because they run on your own machine. Only the API has an allowance, starting at sixty requests an hour free.
- Which one spots a jailbreak attempt?
- AIQualityHQ, through a deterministic scanner. Asking a model whether a prompt is safe gives an opinion rather than a repeatable result.
- What does Claude cost?
- There is a free tier, with paid plans from $20 a month. AIQualityHQ's browser toolkit is free forever with no account.
