Penelope AI

Penelope AI is a browser based writing editor with AI assistance built into the document. Writers draft in the editor and call the assistant inline to continue a sentence, rewrite a passage, paraphrase, summarize or answer questions about an uploaded PDF, without copying text into a separate chat window. It targets students, researchers and content writers producing essays, blog posts, research papers, newsletters, LinkedIn updates and book manuscripts. Autocomplete is triggered by typing two plus signs or opening a slash menu, and composes what comes next in the writer's own flow. Paraphrasing and summarizing tools vary wording, shift tone and condense long documents into key points. Uploaded files can be questioned directly, with chat history retained so a source can be revisited. Documents are unlimited on every tier. Pricing is published in US dollars. The Free plan costs $0 and includes unlimited documents, 50 credits per month for AI features and 10 file uploads per month, with autocomplete, paraphrasing and summarizing each consuming one credit. Ace costs $14 per month billed monthly, or $140 per year on the annual option that the vendor describes as two months free, and lifts AI use and file uploads to unlimited. A Team plan for organizations rolling the editor into a shared workflow is quoted on request. The vendor offers a full refund if requested within 14 days of purchase, and subscriptions can be canceled at any time.
