Ever stopped mid-sentence to open another tab, paste your text into an AI tool, wait, copy the result and paste it back? ContentCraft AI removes all of that. It is a browser extension for Chrome and Firefox that puts AI writing tools directly inside any text field on any website: select text, right-click, done.

What is ContentCraft AI?
ContentCraft AI is a lightweight AI assistant that lives in your browser. Instead of switching between apps, you work where you already are: in an email, a social media composer, a CMS, a comment box or a document editor. Highlight your text and pick what you want the AI to do.
Key features
1. Rewrite in the tone you need
- Formal: polish a message for a client, boss or application
- Casual: make stiff writing sound friendly and natural
- Shorter: trim long paragraphs down to the point
- Longer: expand a rough idea into fuller text
- Fix: correct grammar, spelling and punctuation in one click
2. Summarize anything
Select a long article, email thread or report and get a clear, short summary in seconds.
3. Translate on the spot
Translate selected text between English, Spanish, French, German, Japanese and Hindi without leaving the page.
4. Instagram captions with hashtags
Describe your post and ContentCraft AI writes a ready-to-use caption along with 5 relevant hashtags.
5. YouTube captions and descriptions
Creators can generate video captions and full descriptions from a few raw notes, saving time on every upload.
Two quick ways to use it
- Right-click menu: select text, right-click and open the AI Tools menu to choose an action.
- Quick toolbar: double-click in a text field and a small toolbar appears with the most common actions.
Choose your AI provider
ContentCraft AI is not locked to a single service. You can pick the engine that suits you:
- Chrome built-in AI (default in Chrome): runs on your device, fast and private
- Hugging Face: access a wide range of open models
- NVIDIA: hosted models for higher-quality output
- Ollama: run models locally on your own machine for full control
Note for Firefox users: Chrome's built-in AI is specific to Chrome, so on Firefox you will use one of the other providers (Hugging Face, NVIDIA or Ollama).
Who is it for?
- Students summarizing readings and polishing essays
- Professionals writing clearer emails and reports
- Content creators producing Instagram and YouTube copy faster
- Multilingual users who translate and write across languages every day
How to get started
- Install ContentCraft AI from the Chrome Web Store or the Firefox Add-ons page.
- Open the extension settings and choose your AI provider.
- Select any text on any page, right-click and open AI Tools, or double-click in a text field for the quick toolbar.
