It can write full articles, product descriptions, emails, social posts and SEO meta tags, and rephrase, shorten, expand or summarize text.

Questions

What can the AI do in Writesonic?

The AI can write articles, blog ideas, intros, outlines, paragraphs, ads, emails, subject lines, product descriptions, review replies, social posts and meta tags. It can rephrase, shorten, expand, summarize or change the tone of text, extract keywords, generate images and ask ChatSonic. It can also read GEO visibility data and page issues for your tracked sites.

Does the AI see my Writesonic credentials?

No. Your Writesonic credentials are encrypted at rest and never shown to the AI. After you save them, they are not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can for example allow the GEO reports but not the writing tools. Any tool can require your approval before it runs, and every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your PipMCP link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

PipMCP has a free plan with no credit card required. Paid plans bill per completed task. You also need your own Writesonic account. Most writing tools use credits from your Writesonic account.

Does the AI publish anything on my site?

No. The writing tools return text to the chat, and the GEO and audit tools only read data. Nothing is posted to your website or social accounts. You decide what to use and where.
