A prompt library and management layer for ChatGPT and other AI models
Thousands of community and team-verified prompt templates across industries, each with usage counts and user votes so you can pick proven prompts rather than guessing.
Save your own templates for reuse, group them into named lists such as copywriting or legal, star favorites, and hide noise you never want to see again.
Multi-seat plans give a team one shared private prompt space, keeping instructions, tone, and output formats consistent across everyone's AI sessions.
Selectors let you shift the tone and style of an answer without rewriting the prompt, and paid plans let you define your own custom tones.
Chat with any PDF, video, or website and get cited answers in seconds
Every response is anchored to your source document with clickable citations that scroll to the exact passage, so verification takes seconds instead of page-by-page searching.
Organize documents into folders and query many files in a single conversation to compare arguments, cross-reference findings, or study a whole syllabus at once.
Condense long papers, reports, and contracts into key takeaways, and translate or query documents in any language — including mixing a source language with a different question language.
Generate flashcards and slide decks from your material, and use the built-in AI writer and AI detector for drafting and checking academic text.
