Collect selected text from multiple pages and turn it into one source-aware, token-sized prompt for any AI assistant. Stop juggling tabs and repeatedly copying source text into AI chats. ContextCrate lets you collect useful excerpts from multiple webpages, arrange them into a context stack, and copy one clean prompt that works with ChatGPT, Claude, Gemini, Copilot, or any other AI assistant. HOW IT WORKS 1. Select useful text on any webpage. 2. Right-click and choose “Add selection to ContextCrate.” 3. Repeat across as many pages as you need. 4. Choose a task template, check the token estimate, and copy your prompt. FEATURES • Multi-page context collection with page titles and source URLs. • Built-in templates for summaries, comparisons, fact-checking, and executive briefs. • Source-aware output with simple [S1], [S2] citations. • Approximate token budget for 8K, 32K, and 128K context windows. • Reorder or remove excerpts before export. • Copy the result or download it as a Markdown file. PRIVATE BY DESIGN All excerpts and settings stay in Chrome's local extension storage. ContextCrate has no backend, account, analytics, ads, or external network requests. It never sends your collected text to an AI service — you decide where to paste the finished prompt. ContextCrate is a context preparation tool. It does not generate AI responses itself and is not affiliated with any AI provider.
