Casper AI

What is Casper AI?
Casper AI is a Chrome extension for copywriting and research workflows that summarizes web pages and PDFs so you can brief articles, track policy changes, or scan deal documents without reading every word. It runs inside the browser, pulls text from the page you are on, and turns long sources into short notes you can share with teammates.
Where many sidebar assistants chase open-ended chat, Casper AI stays closer to analyst-style reading work. It highlights new insights from public sources, compresses news into shareable summaries, and focuses on understanding and distributing findings rather than generating full drafts from scratch. That narrow scope suits professionals who need quick comprehension more than long-form content generation.
The Chrome Web Store listing targets analysts, strategists, policymakers, and business developers who prepare for exams, research investments, work on deals, or track new laws. Version 0.4.2 lists about 10,000 users and a 4.4 out of 5 rating from 77 reviews, with English as the only supported language.
Jenni AI

What is Jenni AI?
Jenni AI is an academic writing workspace where autocomplete suggests the next sentence grounded in PDFs you imported from Zotero, Mendeley, or its 200 million paper search index. Each suggestion links to the exact page and paragraph in your source so you can verify claims before accepting them.
ChatGPT-style chatbots generate fluent paragraphs without tying sentences to your library. Jenni AI keeps research inside one workspace where autocomplete can draw only from sources you select, inline citations cover 10,000 plus styles, and AI chat answers questions across your full PDF library with references.
Graduate students drafting theses, researchers writing literature reviews, and academics exporting to Word or LaTeX are the core users Jenni AI describes, claiming 6 million plus academics and an average of 5.2 hours saved per paper.
Free accounts get 10 AI autocompletes per day and 10 PDF uploads. Plus costs $12 per month with 5,000 autocompletes monthly, and Pro at $29 per month removes limits on autocomplete, chat, edits, and reviews.
