## Overview
Penelope AI is a browser-based writing assistant built around a markdown editor, aimed at people who draft long-form text rather than short social posts. Typing "++" or "/" triggers an AI autocomplete that continues a sentence in the writer's existing voice, while separate tools handle paraphrasing (with four tone options), summarizing long passages, and generating short stories from a handful of keywords. A PDF chat feature lets users upload documents and ask questions about their contents directly inside the editor, useful for pulling quotes or checking facts while writing.

The tool targets a fairly broad writing audience — students working on essays, bloggers, researchers, business professionals, authors, and newsletter writers — rather than any single niche. Documents are stored in an unlimited workspace, so users can keep multiple drafts and reference material in one place.

Penelope AI reports over 17,000 active users. It offers a free tier with 50 AI credits and limited uploads, a $140-per-year Ace plan with unlimited use, and custom Team pricing for larger groups, backed by a 14-day refund guarantee. The site does not disclose who built the product, when it launched, or whether a developer API exists beyond a passing FAQ mention.
