ThinkMode+ — Auto-Enable ChatGPT Thinking Mode. Set It Once. Never Click Again. Tired of manually enabling "Think" or "Deep Research" every single time you open ChatGPT? Done pasting the same "act as a senior developer" prompt on every conversation? ThinkMode+ eliminates that friction entirely. ThinkMode+ is a lightweight Chrome extension that automatically activates ChatGPT's extended thinking (reasoning) mode the moment you start a new conversation — no clicks, no manual setup, no repetition. ────────────────────────────────────── 🧠 CORE FEATURES ────────────────────────────────────── 🔁 Auto-Enable Think Mode ThinkMode+ detects your ChatGPT composer on every page load and automatically activates extended thinking based on your saved preference. Reasoning mode, always on — without a single click. 🎭 Expert Roles & AI Personas Stop starting every chat with "Act as a senior developer." ThinkMode+ injects your chosen role silently into every prompt the moment you hit send. Built-in roles include: - Senior Software Developer - Financial Analyst - Devil's Advocate - Socratic Teacher - UX Critic - Research Scientist - First Principles Thinker …and you can create unlimited custom roles. 🎯 Precision Mode Need facts, not hallucinations? Toggle Precision Mode to automatically append a system directive that instructs ChatGPT to reason step-by-step and verify factual claims before responding. 📐 Output Format Bar Format your ChatGPT responses without rewriting prompts. Instantly switch between Table, Steps, Code, Comparison, and Bullet output formats from the floating control bar. ⚡ Follow-Up Prompt Bar One-click follow-ups appear automatically after every ChatGPT response: Go Deeper, Simplify, Give an Example, Challenge This. No retyping. Just click. ⌨️ Keyboard Shortcut Toggle ThinkMode+ on or off globally with Ctrl+Shift+T (Cmd+Shift+T on Mac) — from any ChatGPT tab, instantly. 🔔 UI Health Alerts If ChatGPT updates its interface and breaks the auto-activation, ThinkMode+ sends you a desktop notification so you always know when manual intervention is needed. ────────────────────────────────────── 🛡️ PRIVACY & TRANSPARENCY ────────────────────────────────────── ThinkMode+ is built with privacy as a baseline, not an afterthought. ✅ All processing happens locally in your browser ✅ No browsing history or chat data sent to our servers ✅ No analytics or telemetry from the extension ✅ Settings synced via Chrome's own storage API ✅ Authentication handled by Supabase — we never see your password The optional Precision Mode feature modifies outgoing messages client-side only to append a fixed directive.
