Common questions
Are the AI writer tools really free?
Yes. There is no sign-up and no subscription. A fair daily limit on generations applies to each visitor, and it resets every day.
Which AI model writes the text?
The drafts are written by an OpenAI GPT model, called by A2Z Tools on your behalf. You never need your own API key.
Do you keep what I write?
Your recent results are stored only in your own browser so you can restore them later. Clearing your history removes them from this device.
Can I trust the output as-is?
Treat it as a strong first draft. AI can make mistakes, so check names, facts, dates and figures before you send or publish anything.

What is this tool?
AI Writer is A2Z Tools' set of 18 focused AI writing tools. Each one is built for a single job - replying to an email, drafting an article, checking grammar, summarising a report, explaining a school topic - with a short form that asks only for what that job needs.
Every tool works the same way: fill in the form, press Generate, and refine the draft with one click until it fits. The tools are free, need no account and are powered by an OpenAI GPT model.
How to use it
Choose by task. Answering a message? Use the Email Reply Writer. Waiting for a response? The Follow-Up Email Writer. Have text that needs work? The Grammar Checker fixes errors, the Paraphraser rewords, the Text Shortener tightens and the Summarizer pulls out key points. Starting from nothing? Try the Idea Generator, Title Generator or AI Article Writer.
- Pick the tool that matches your task from the list.
- Fill in the short form - a topic, text or details, plus tone and length where offered.
- Press Generate to get a draft in seconds.
- Refine, regenerate or edit the draft.
- Copy it or download it as .txt or Word.
Example
A typical workflow: use the Idea Generator for blog topics about saving energy at home, send the best one to the Title Generator for headlines, draft the post with the AI Article Writer, and finish with the Grammar Checker. Each step takes seconds, and you edit between steps.

Privacy & your data
What you type is sent through the A2Z Tools server to an OpenAI GPT model (gpt-4o-mini) to create the result. A2Z Tools does not store the text you enter or the results on its servers; it keeps only anonymous usage counts to apply the fair daily limit. Your recent results are saved only in your own browser (localStorage), and you can clear them at any time.
The same privacy approach applies to every tool in the set, and you can clear saved recent results from your browser whenever you like.
