Questions
Frequently asked questions
- What is Cofounder?
- Cofounder is a natural-language automation tool for knowledge workers. You describe what you want in plain English and Cofounder writes the automation, runs it across your existing tools, and keeps it maintained — no triggers to configure, no agents to babysit.
- Which tools does Cofounder integrate with?
- Cofounder plugs into the software knowledge teams already use, including Linear, Notion, Slack, and Gmail. Automations are written once in plain English and executed natively across those tools.
- How is Cofounder different from Zapier or n8n?
- Zapier and n8n require you to manually define triggers, actions, and field mappings. Cofounder takes one English sentence — for example, “Every Monday, email me a digest of new posts from these tech blogs” — and produces, schedules, and maintains the automation for you.
- Do I need to be technical to use Cofounder?
- No. Cofounder is designed for founders, operators, and small teams. If you can describe the outcome you want, Cofounder handles the steps, the tools, and the schedule.
