# Nexin

> Nexin is an everyday assistant for working with AI: a library of ready prompts, skills for Claude, templates, tutorials and paid tools that fetch real data on credits (https://nexin.si/library), such as a social profile scraper and a keyword volume checker. On Pro it also works inside Claude, ChatGPT and any MCP app through one connector (https://nexin.si/mcp). The browser tools (converters, compressors, PDF and text tools) are free on their pages, with no sign-up; the prompts, skills, templates and tutorials open with a plan. Two plans: Nexin Lite ($14 once, a 7-day money-back guarantee: the library, for good) and Nexin Pro ($19/month, 7 days free: the library, the connector and 900 credits a month for the paid tools). After a first Pro payment the account keeps Lite for good, even if Pro is cancelled later (a trial cancelled before paying keeps nothing); credits run only on Pro. Credit packs from $10 once. Cancel Pro any time. Desktop app (beta, Mac): https://nexin.si/download.

Every public page is also served as Markdown: add `.md` to its URL (https://nexin.si/index.md for the home page), or request it with `Accept: text/markdown`.
