Hear From Our Happy Users

BenChrome Web Store · Jan 2026

If you're like me and you use Claude & ChatGPT seriously, you probably have a Notion doc somewhere with "who I am, my business, my tone", etc. that you copy and paste into every new chat.

At the same time, 90% of people I meet who say "AI doesn't work for me" simply aren't giving enough context.

This extension fixes both situations. Set up your profiles once then inject them when needed. Going to save so much time.

Jorem BellenChrome Web Store · Jan 2026

This is great extension, especially for people using multiple LLMs in their workflow. The dashboard is a nice touch. An easy way to keep track of context profiles.

Pavel BantsevichChrome Web Store · Jan 2026

Each team member has their own profile (Marketer, Video Creator, Sales, Project Manager, etc.), and we went a step further by adding personal traits so the output matches their individual style. The setup just works in the background and removes a lot of friction.

Артем ЛеверяChrome Web Store · Sep 2026

Honestly, one of the most useful Chrome extensions I’ve tried in a while. The workflow is simple, fast, and actually saves a lot of time when working with prompts.

Aonnoy SenguptaChrome Web Store · Jan 2026

It helps me clean up prompts and tighten up wording really fast, without feeling like I’m fighting a bunch of extra menus or settings.

Lipika RoyChrome Web Store · Jan 2026

The best extension in the internet. It always remember your context. Thank you for the amazing gift.

Why I built Nject

“I dreamt of building the product I would actually use.

At God of Prompt we genuinely tried to improve the experience for our 180,000 users, and I remember the eureka moment: why not deliver the prompt, with your context in it, straight into the AI tool, right where you type?

So we built it. Save your context once, and it comes with every prompt you write in ChatGPT, Claude, Gemini, Grok and Perplexity.

Along the way it grew into something our own team used while building it.

Working across every platform became our moat. The AI companies compete with each other, and a neutral layer works with all of them: your context stays with you, whichever AI you open.

It is the product we use ourselves, made for everyone who would rather get to the answer.”

FAQ

  • Nject is a Chrome extension and web app that remembers your context: your business, your audience, your products and the way you write. You save it once as a profile, and Nject adds it to your prompts in ChatGPT, Claude, Gemini, Grok and Perplexity, so every chat starts with the AI already knowing who you are.

  • A profile holds the background an AI needs to give you a useful answer: what you sell, who you sell it to, your goals and your tone of voice. Without one you retype that background in every new chat. With one you pick the profile, write your request and send. You can keep separate profiles for a business, a project or a writing style.

  • Type your request the way you would say it. One click turns it into a clear, structured prompt with the right context from your profile, and you review the result before it is sent. Autocomplete also suggests the rest of your prompt as you type.

  • Nject works inside ChatGPT, Claude, Gemini, Grok and Perplexity, and in Google AI Mode and Grok on X too. The same profile follows you between them, so switching tools no longer means starting from zero.

  • You do. Everything you save in Nject, your profiles, their files and your memory, belongs to you. We use it only to write your prompts and keep your memory. Our team doesn’t read it, and we never sell it.

  • Every connection to Nject is encrypted with HTTPS. Passwords are stored as one-way hashes and checked against known leaked passwords, and each profile, file and memory opens only for the account it belongs to. An independent security firm tested the extension, the web app and the API in September 2026.

  • Yes. Delete a profile in your dashboard and its answers, links, files and memory are removed with it. To pause Nject at any time, switch it off from its toolbar icon.

  • Nject runs in Google Chrome on a computer, where you add it from the Chrome Web Store.
