Looking for a PromptPerfect alternative?
Updated August 2026
PromptPerfect, the prompt-optimization service previously priced around US$20-50 a month, has been reported discontinued. If you relied on it, here is how IterationFlow compares.
What IterationFlow does differently
- Per-model rewriting, not generic polish. 13 targets across Claude, GPT, Gemini, Grok, Llama and DeepSeek, with separate handling for reasoning models versus standard ones, because the same prompt style measurably helps one family and hurts another (DeepSeek’s own paper shows few-shot examples degrade R1).
- Image models too. Rewrites tuned for Seedream, Nano Banana Pro, GPT Image, Midjourney, FLUX, Ideogram and more, in the style each generator’s documentation recommends.
- Context-aware rewriting. Save project and business context once, or sync it from your Obsidian vault, and every rewrite carries the details you’d otherwise retype.
- Rules traceable to official guidance. Every rewrite follows the vendor’s published prompting documentation, re-verified against primary sources, not folklore.
- Nothing invented. Missing details become clearly marked placeholders, never guesses. Your facts stay yours.
- We don’t store your prompts. They are processed and returned; history lives only in your browser.
- Simple pricing in AUD. 5 days free, one text, one image and one video prompt a day. A card is required to start and the first charge is on day 6, from A$15/mo to A$59/mo. Cancel any time.
