Infinithink AI Writer
AI content generator for blogs, ads and product pages
Turn a short brief into a blog post, product description, email, ad or social post. Pick from 130+ specialized writing tools, apply your Brand Voice and finish the draft in the editor.
What you can write with the AI writer
Templates are grouped by job. Each one asks only for the details it needs, such as the product, the audience or the keywords, and then writes. You choose the output language, the tone and how many variations you want.
-
Blog posts and articles
Blog Post Ideas, Blog Outline, Blog Intro and Blog Article take a post from topic to full draft. Work one section at a time when you want control, or in one pass for a first version you'll rework.
-
Product descriptions
Product Description, Product Features and the Amazon listing template start from the product name and its specs, for your own store, a marketplace or a catalog.
AI product description generator, Product descriptions -
Emails and newsletters
Cold Email, Follow up Email, Welcome Email, Newsletter and Reply Email cover the messages a small team writes every week, from a first contact to the answer to a tricky customer question.
-
Google and Meta ads
Google Ads Headlines, Google Ads Description and Facebook Ads give you several variants in one run. Check each line against your offer and your ad platform's character limits before it goes live.
-
Social media posts
Instagram Captions, Facebook Post, X Thread and the hashtag templates turn one idea into a post for each channel, in the same Brand Voice.
-
Headlines and press releases
Post Title Generator suggests headlines for articles, pages and newsletters. Press Release structures an announcement with a headline, a lead, the details and a short company description.
-
LinkedIn posts
LinkedIn Post drafts updates for a company page or a founder's profile, from a product launch to a lesson learned on a project.
-
Website copy
Landing Page Content, Services Page, Tagline and Call to Action help with the pages that explain what you do. Start from what you sell and who it's for.
-
Your own templates
Turn the instructions you repeat into a template with the fields your team fills in, then reuse it every week.
Long-form articles with the AI Article Wizard
For longer pieces, the Article Wizard works in steps. Enter the topic and the keywords you want to target, pick a title from the suggestions, adjust the outline, then generate the article from that outline. It's the AI SEO content generator inside Infinithink. Your keywords shape the title, the headings and the body, and the Meta Description template writes the snippet for search results.
An AI article writer gives you structure and a solid first draft. It doesn't know your customers, your numbers or your opinions. Add them before you publish, because that's what makes an article worth reading and worth ranking.
Edit, rewrite and translate in the AI Editor
Any draft can be finished in the AI Editor, a document where you write and ask the AI for help on the text you select, for example to rewrite it, change the tone or translate it. The AI ReWriter reworks an existing text from scratch, and Grammar Check, Proofreading, Rephrase and Translate help with the final pass. Useful when you need the same page in English and Italian.
Brand Voice and custom templates
Brand Voice stores what makes your writing yours: your company, what you sell, who you sell to and how you talk. Select it in any template and the AI content generator writes from that context instead of guessing.
Custom templates turn your own instructions into a reusable tool, with the fields you want your team to fill in. If you write the same kind of text every week (a quote follow-up, a property listing, a monthly update for clients), build it once as a template and reuse it.
Choose the right AI model for each draft
Infinithink works with several AI models, and you choose one for each task. These are starting points, not rules. Run the same brief on two models and keep the draft you prefer.
| Model family | Provider | A good fit for |
|---|---|---|
| GPT | OpenAI | Everyday drafts, short copy and template work |
| Claude | Anthropic | Long articles, careful editing and copy where tone matters |
| Gemini | Long source material and analysis-heavy writing |
The table scrolls sideways on small screens. Use the arrow keys when it has focus.
Free uses GPT models, Claude and Gemini come with Starter, and Business adds the most capable models. The AI model comparison lists the models in each plan.
Review before you publish
AI drafts can contain mistakes, invented facts or wording close to existing content. Before anything goes live:
-
Check facts, figures, names and prices against your own sources.
-
Make sure every claim about your product is true and that you can back it up.
-
Read it aloud and cut the generic phrases nobody at your company would say.
-
For SEO content, add first-hand experience and examples, not just keywords.
-
Disclose AI use where the law or your industry asks for it.

FAQ
What is an AI content generator?
A tool that drafts text from your instructions using a language model. In Infinithink you fill in a template or describe what you need, choose a model and get a draft you can edit, save and reuse.
Is AI-generated content bad for SEO?
Not in itself. Google says it rewards helpful content however it's produced, and treats content made mainly to manipulate rankings as spam. Use the AI writer for structure and first drafts, then add expertise, examples and checked facts.
Does the AI writer work in Italian?
Yes. Set Italian as the output language in the template, or write your brief in Italian. English and Italian are the languages we write and check our own examples in, so for other languages, have a native speaker review the result.
Can I use AI-generated content for client work?
Yes. Under our Terms, any rights we may have in the output are assigned to you. AI output may not be protected by copyright and similar text can be generated for other users, so add your own work where originality matters.
Which model should I use for writing?
Start with GPT for everyday drafts and try Claude for long articles and careful edits. The simplest way to decide is to run the same brief on both and compare.
Is there a free AI writer?
The Free plan costs €0 and includes monthly credits and 130+ specialized writing tools. You register with your email, no credit card required. Paid plans start at €12 a month.
