The short answer
ChatGPT and Claude are general AI assistants. They are excellent at research and writing, and in 2026 both can browse websites, run tasks on a schedule and, with your mailbox connected, send emails you approve. Neither comes with its own database of companies, contacts, technologies or buying signals: they rely on web search or on data tools you connect.
Coolie is an AI GTM agent built for outbound. Every day it watches buying signals, such as companies dropping a competitor, keeps those that fit your ICP, finds the decision makers, writes the research and the sequences, and sends email and LinkedIn steps from your own accounts.
You don't have to choose: through Coolie's MCP server, Claude or ChatGPT can drive Coolie for you.

What ChatGPT and Claude do well
- Writing. Drafts, rewrites in another tone, subject lines, translations, follow-ups.
- Research. A summary of a company or a person from the web, with its sources.
- Acting for you. ChatGPT's cloud browser and Claude in Chrome can read pages, click and fill in forms, and both can run tasks on a schedule.
- Connectors. Gmail, Outlook, CRMs and data tools, and custom MCP servers on the plans that allow them.
Where Coolie is different
- The leads come to you. Coolie watches buying signals every day. Competitor Churn finds companies that cancelled, downgraded or stopped using a competitor's product in the last 90 days. Competitor Renewal finds companies that adopted a competitor 9 to 12 months ago, so a yearly contract is likely to renew in the next 3 months. Tech Used finds the companies that use a given tool today. Hiring, funding, acquisitions, job changes, LinkedIn engagement and intent topics come with them.
- People, not just companies. Coolie keeps the companies that fit your ICP, finds the decision makers whose job titles match it, and scores each lead.
- Built to run every day. No prompt to write each morning: each agent runs on its own schedule and every lead shows the signal it was found on.
- Sending at a steady pace. Email and LinkedIn steps go out from your own mailbox and LinkedIn account, spread over your working hours and within the daily limits you set. A sequence can pause when a lead replies, and every email carries an unsubscribe line.
- One place for the whole chain. Leads, research, sequences and replies live together, so nothing is copied from one tool to the next.
Use them together
Coolie has an MCP server. Connect it to Claude, or to ChatGPT on the plans that accept custom MCP servers, and the assistant can create and start Coolie agents, read your leads, find a contact, research leads, write sequences and launch or pause campaigns. The messages still go out through Coolie, from your own accounts and within your limits. See the API documentation.
Who should use ChatGPT or Claude alone
- You write to a handful of people you already know.
- You already have a lead source and a sequencer, and want help with the writing.
Who should choose Coolie
- You want new leads every day from buying signals, starting with your competitors' customers.
- You want the decision makers found, and the sequences written and sent from your own email and LinkedIn.
- You want your AI assistant to drive it: connect Claude or ChatGPT to Coolie.
