| Description | ChatPDF is an AI document assistant that lets you upload PDFs (plus Word, PowerPoint, Markdown, and text files) and ask questions in natural language, returning answers linked back to specific pages so you can verify sources. It's aimed at students turning readings into study notes and at analysts, researchers, and consultants skimming long reports for key takeaways. Its main differentiator is being one of the earliest, simplest ChatGPT-style PDF chat tools, with cited page references and no account required to start. | SignalZen is an AI-powered customer support and live chat platform for small and medium businesses. Its AI answers from your website, files and help center and hands conversations to human agents. The platform includes a customisable chat widget, an AI copilot that drafts replies for agents, a public knowledge base, two-way translation and conversation summaries. Agents can reply from Slack, Microsoft Teams or Google Chat. Plans are monthly: Starter is $29 (up to 2 operators), Basic $49 (up to 5), Pro $99 and Business $199 (both unlimited operators), with a 30-day free trial and no permanent free plan. |
