one model • six jobs • zero dollars
🪄 Right-click → free writer → any box on the internet
Right-click any text field in Chrome → Help me write → type 3 words (“complain, late parcel”) → it hands you a full draft you tweak and drop in. Gmail, forms, marketplace listings, comment boxes — anywhere you type.
The fine print they mumble: it shows only if you’re US + English + signed-in, with “Make searches and browsing better” switched ON — and that toggle quietly ships the web addresses you visit off to Google. Good to know before you flip it.
🌍 Locked out 'cause you're not American? One line fixes it
Outside the US and the menu’s dead? Skip the whole VPN headache. Start Chrome with one scrap of text glued on — --variations-override-country=us — and it acts like it’s in the States, flipping the AI on. Save it as a chrome-us shortcut and it’s one click forever.
The one-command unlock + shortcut setup
Backup move — set Google payment country to US bends Google’s rules, do it on a spare account
🕶️ The one they bury: free AI, no internet, snitches on no one
Here’s the part nobody spells out. That same brain? You can talk to it straight — offline, sending your words nowhere. It’s called the Prompt API (just “poke the local AI with a tiny snippet of code and it answers”). No signup, no API key (the password apps normally need), no wifi once it’s downloaded. Same model writes, translates, rewrites, and proofreads — one free brain, every job.
The right-click writer phones home. This one doesn’t. That’s the whole trick. It blew up to #1 on Hacker News (the geek front page) for exactly that reason.
Flip it on: chrome://flags → search “prompt api for gemini nano” → Enabled → relaunch. Check it landed at chrome://on-device-internals.
Paste a prompt, watch it answer — zero code
Dead-simple walkthrough
🛠️ Turn it into your own free gadget (the code's right here)
Once it clicks that a free AI is just sitting there, you bolt it onto whatever you want — costs nothing, runs offline. Folks already built little Chrome add-ons on it, like one that watches a YouTube video and hands you the summary, all on your own machine. Grab the entire working thing and make it yours:
A real, free add-on you can copy
You don’t need to be a coder to feel this — it’s the gap between renting an AI app and owning a free tool nobody can switch off on you.
🎭 Where it's a dumbass — so you don't get burned
Don’t buy the “super accurate” hype. The people who actually build on it call it “the autocomplete of AI” — and Google itself admits it’s “not great with facts.” It’ll make stuff up with a straight face and choke on long text. Use it like spellcheck on steroids — for real answers, open the full Gemini or Claude.
The honest “here’s what it sucks at” breakdown
Keep prompts short. Feed it a wall of text and it forgets the start by the time it hits the end.
⚡ The talky sidebar + the bit for the EU crowd
Want the chatty one that reads the whole page and compares your open tabs? Tap Alt+G or type @gemini + Tab in the address bar — it summarizes pages, juggles 10 tabs, even talks back out loud.
EU / UK / Switzerland — you’re walled off (lawyer stuff, not your fault). Don’t burn hours VPN-fighting it; just use the Gemini website or the “Gemini for Chrome” add-on instead.
You came for a writing button. You’re leaving with a free AI that runs offline — and the code to build your own. Go poke chrome://flags and see what falls out.
