The best free AI prompt generators in 2026
Facts checked on October 10, 2026. Sources are listed at the end.
A prompt generator turns a rough request into a prompt the AI can act on: who it is for, what good looks like, the format and the length. "Free" means different things here: some tools generate prompts, some give you a library to copy from, and one well-known optimizer has shut down. This guide compares the options people actually use, what each is good at, and where each falls short. We make Verbito, so weigh our view accordingly; every claim about the other tools links to its source.

Generator, library or optimizer: which do you need?
A library (AIPRM, prompts.chat) gives you prompts other people wrote. That is fast when your task matches a template, and weaker when it does not, because the template does not know your audience, goal or constraints.
A generator (Verbito) starts from your own description and builds the prompt around it: role, context, task, constraints and output format. An optimizer did the same for an existing prompt; PromptPerfect was the best-known one and is now closed.
Asking ChatGPT or Claude to "improve my prompt" works for a quick fix. What it does not give you is a consistent standard: you cannot tell whether the new prompt is actually better, or what it is still missing.
Why scoring matters
Vague prompts get generic answers because the model has to guess the audience, the goal, the format and the length. A score makes those gaps visible. Verbito scores any prompt from 0 to 100 on seven dimensions (clarity, context, specificity, constraints, output format, reusability and token efficiency) and lists the exact fixes. "Tell me everything about marketing" scores 28; a rewritten version with a role, an audience, five channels, a format and a word limit scores 88.
The scorer runs in your browser, needs no account and has no limit, so you can check prompts from any tool, including ones you got from a library.
What the free tiers really include
Verbito: Free: 2 prompts a day without an account, 5 with a free account; the Prompt Scorer is free and unlimited. Paid plans: Starter $12/mo, Pro $29/mo, Unlimited $79/mo (annual plans cheaper).
AIPRM: a free plan plus paid tiers (Plus, Pro, Elite and Titan for individuals; Team, Business and Enterprise for organizations), sold in US dollars with two free months on yearly billing. Its pricing table loads in the browser and did not render for us, so check current prices on aiprm.com/pricing.
prompts.chat: completely free and open source. It is a library, so there is no generation or scoring.
Arabic prompts
Few prompt tools handle Arabic well. Verbito generates Arabic prompts and gives Arabic feedback when the prompt is in Arabic, even if the site is in English. Libraries depend on what the community has written; asking the AI directly in Arabic works but without any structure or score.
The verdict
If you want a ready-made template inside ChatGPT, a library like AIPRM or prompts.chat is quick. If you want a prompt built around your own task, with a score that shows why it works, start with Verbito: the scorer is free and unlimited, and generation is free for a few prompts a day.
Frequently asked questions
- What is the best free AI prompt generator?
- It depends on the job. For a prompt built around your own task with a quality score, Verbito is free for 2 prompts a day (5 with a free account) and its scorer is unlimited. For browsing ready-made prompts, prompts.chat is free and open source, and AIPRM has a free plan.
- Is PromptPerfect still available?
- No. Following Jina AI's acquisition by Elastic, PromptPerfect's own site states it is no longer available after September 1, 2026.
- Can ChatGPT write prompts for itself?
- Yes, you can ask it to improve a prompt, and that helps for quick fixes. It does not score the result, so you cannot tell whether the new prompt is better or what is still missing.
- Do I need an account to use Verbito?
- No. The prompt scorer and 2 generated prompts a day need no account. A free account raises that to 5 a day and saves your prompts to a library.
