What is PromptFix?
PromptFix is an app creation tool that rewrites your AI prompts before you send them. PromptFix rewrites the questions you type into ChatGPT, Claude, Gemini or Perplexity so the answers come back sharper.
PromptFix is a prompt improvement tool for people who already use ChatGPT, Claude, Gemini or Perplexity but keep getting vague or off-target replies. You paste the message you were about to send, and the service rewrites it into a clearer request: it adds the context the model is missing, states the format and length you want, identifies the audience, and replaces loose wording with specifics. The homepage example turns a one-line request about a broken heater into a polite but firm email brief with a subject line and a deadline. Turnaround is advertised at under a minute. The tool is built around a few connected surfaces. A web app handles the core rewrite and shows a plain-language breakdown of what was weak in the original prompt and what changed. A free Chrome extension does the same job inline inside ChatGPT, Claude, Gemini and Perplexity once an account is connected. On top of that sit 31 step-by-step workflows for recurring jobs (meeting notes into action items and a follow-up email, a syllabus into a study plan, a week of meals into a grocery list) and a library of 300+ ready-made templates, 25 of which are free. Paid tiers add A/B testing, side-by-side comparison of answers across models, saved preference profiles for tone and standing details, and a Reverse Prompt feature that reads an uploaded image and generates a prompt to recreate it. The audience is deliberately broad: students, office workers, small business owners and anyone doing personal admin who uses AI often enough to notice the quality gap but has no interest in learning prompt engineering formally. Practice games and an academy with a shareable certificate push in the same direction. Compared with prompt libraries that simply hand you static snippets, PromptFix sits closer to a linter for your own wording, and its model-comparison view is a useful check before committing to one assistant.
How do you use PromptFix?
1Paste the question you were about to ask
Open the web app and drop in the exact text you would normally type into ChatGPT or Gemini. There is no need to tidy it first; rough phrasing is the input the tool expects.2Read the rewrite and the explanation
Review the improved prompt alongside the breakdown of what was vague, missing or unstated. Use the notes to learn the pattern rather than just copying the output.3Install the Chrome extension
Add the extension and connect your account so future prompts can be improved inline inside ChatGPT, Claude, Gemini and Perplexity instead of a separate tab.4Pick a workflow for a recurring job
Choose from the 31 workflows, such as meeting notes into action items or a syllabus into a study plan, and fill in the details the steps ask for. The free plan includes 3 workflows permanently plus one try of any other each month.5Compare how different models answer
Run the same rewritten prompt through more than one assistant side by side to see which gives the most usable reply. This is available from Starter upward.6Check pricing and the student discount
Confirm which plan matches your usage, and if you have a verified school email, apply the 50 percent student rate on Starter or Pro.
Pros and cons
Pros
- Explains in plain language what was missing from your original prompt, so the improvement is visible rather than hiddenAI
- Free Chrome extension works inside ChatGPT, Claude, Gemini and Perplexity, which is where most people actually typeAI
- Free plan is genuinely usable: 15 improvements a month, 3 workflows and 25 templates with no card requiredAI
- Model comparison and A/B testing let you check whether a rewrite really helps before trusting itAI
- Workflows cover concrete recurring chores like meeting notes, study plans and grocery lists rather than abstract prompt tipsAI
Cons
- The free tier's 15 monthly improvements will not last a heavy daily user, effectively pushing regulars to the $9 Starter planAI
- Model comparison is capped at 3 models on Starter and 4 on Pro, so broader testing across many assistants is not on offerAI
- Reverse Prompt, the most distinctive extra, is locked to the $29 Pro tier with no smaller way to try itAI
- No API is mentioned, so teams wanting to wire prompt rewriting into their own tools have no documented routeAI
- Value depends on the underlying model: a rewrite cannot fix a question whose premise is wrong, and the tool does not claim toAI
