Free Prompt Improver
Improve a prompt without a paid trial clock.
Before
give me ideas for a newsletter
After
Role: newsletter editor. Audience: junior PMs. Task: 8 subject lines + 1 outline for a 400-word issue on writing better AI briefs. Format: numbered list. Constraints: no celebrity names, no engagement-bait.
The problem
Many improvers hide the tool behind a card or a tiny trial. Promptnator lets you sign up free and polish. We do not pretend generate is anonymous. The free account is the honest door.
What free includes
1. Magic Polish
Rant to structured prompt.
2. Compile targets
ChatGPT and other free targets.
3. Precision Score
See what is still thin.
4. No card
Paid plans are optional, monthly, cancel anytime.
Do it in one click
Create a free account and run one polish in Studio.
Honest take
Unlimited anonymous polish is something some browser extensions claim. We require a free account so quotas and abuse controls can exist. If you need a huge public template library, PromptPerfect-style catalogs may fit better.
