About
PI Labs builds small, fast Chrome extensions that work inside ChatGPT, Claude, Gemini and X: PI Prompts for a prompt library one keystroke away, PI Fix Grammar for on-device grammar fixes in any text field, PI Summarize for right-click summaries, and PI Answer for reply drafts on X in your voice, plus Ciocu, an AI companion. The core features are free forever, and one $10/month key unlocks premium in every tool.
Features
- Problem
- Reusable prompts are difficult to find and reuse while chatting.
- How it works
- PI Prompts inserts saved prompts from a searchable library with a click or Tab key, and syncs the library through the user's Google Drive.
- Result
- Users can reuse and manage prompts without leaving the chat.
- Why
- Keeps frequently used prompts available inside supported chat interfaces.
- Problem
- Writing corrections can require copying text into a separate tool.
- How it works
- PI Fix Grammar corrects grammar in text fields across sites, using on-device Gemini Nano first and cloud fallback when needed.
- Result
- Users can quickly improve writing in place.
- Why
- Prioritizes local processing while retaining a fallback option.
- Problem
- Long pages and selected text take time to digest.
- How it works
- PI Summarize adds right-click summaries for selections or pages via ChatGPT, Gemini, or Claude.
- Result
- Users can get concise page or selection summaries without changing workflow.
- Why
- Makes summarization available on the current page.
- Problem
- Writing authentic replies on X can be time-consuming.
- How it works
- PI Answer drafts or completes X replies in the user's voice and removes specified AI-style tells such as emoji and em dashes.
- Result
- Users can produce personalized X reply drafts faster.
- Why
- Helps create replies that fit the user's established answering style.
- Problem
- Premium capabilities are fragmented across individual tools.
- How it works
- One subscription and shared energy pool unlock premium features across PI Labs extensions and Ciocu.
- Result
- Subscribers use paid capabilities across the product set with one account.
- Why
- Avoids separate license keys and per-tool plans.
