Frequently Asked Questions
Everything you need to know about engines, pricing, permissions, and compatibility.
Do I need a paid API key or credit card to use this?
No, absolutely not. You have complete freedom: you can obtain a 100% free API key from Google AI Studio (no billing, no credit card required, with generous daily free tier limits) for ultra-fast Cloud API performance, run 100% offline with Gemini Nano (zero keys), or use the Headless Direct engine with your active Google login session cookies.
Which AI models can I choose from?
When using the Google Gemini Cloud API engine, you can select from: Gemini 3.1 Flash Lite (default recommended, ultra-fast latency with sub-second generation), Gemini 2.5 Flash, Gemini 2.0 Flash, Gemini 1.5 Flash, and Gemini 1.5 Pro (for deep analytical reasoning). You can switch models anytime in the popup settings.
What is the on-screen Floating HUD widget?
The Floating HUD is an optional draggable control dock that appears directly on your Twitter (π) feed. It displays live status chips for all 4 engines, lets you quick-switch reply tones and post archetypes, offers an inline multiline editor to update custom prompt rules on the fly, and lets you draft standalone tweets. You can drag it anywhere or toggle it off in the extension settings.
How does the Intelligent Fallback cascade work?
If your active engine encounters a temporary network error, rate limit, or model download delay, the extension automatically cascades through available backup engines: Cloud API → Gemini Nano → Headless Web → Gemini Web Tab. This guarantees uninterrupted tweet and reply drafting.
Is this extension completely free?
Yes! The extension is 100% free and open source under the MIT License. There are no paywalls, token limits, or premium subscriptions. If you enjoy the tool, you can support its development through Trakteer ID or Buy Me a Coffee.
How do I check if Gemini Nano works on my Chrome?
You can run a quick 5-second check: press F12 in Chrome, switch to the Console tab, and paste 'LanguageModel' in window || 'ai' in window. If it returns true, your browser supports built-in AI! If not, you can enable chrome://flags/#prompt-api-for-gemini-nano, or simply use the Cloud API or Headless Direct engines which work immediately on every setup.
Will my Twitter (π) account get banned or flagged?
No. The extension does not post automated bot spam. It acts as an editorial copilot: it drafts an intelligent response and places it in your composer for your review. You choose when to edit, polish, and hit the Tweet button yourself.
Can I customize the reply language and length limits?
Yes! Both in the extension popup and on the on-screen Floating HUD, you can specify custom prompt instructions. You can instruct Gemini to always answer in a specific language (e.g. English, Indonesian, Spanish, French, Japanese), enforce "no emojis", keep replies under 180 characters, or instruct it to adopt a specific brand voice.
