What CallMerlin is
CallMerlin describes itself as an AI Chief of Staff that connects to business systems and can be used by phone, chat, widget, desktop, mobile, Slack, and Teams. It supports workflows involving multiple systems, triggers, and an analysis step with auto-inject. Reads can happen immediately, while writes, emails, and payment files wait for approval unless direct execution is enabled. Its integrations page lists 96 native deep integrations and says 900+ are available through managed connectors, including HubSpot, Salesforce, Slack, Moneybird, Microsoft 365, Gmail, Stripe, Shopify, and Zoom. The company says each teammate has an individual PIN and server-side permissions. It states that credentials are encrypted with AES-256-GCM and connections use TLS, with PIN and 2FA access. Call transcripts and summaries are kept for at most 90 days by default; audio is not retained. Starter pricing is €55/mo (annual), with a 7-day trial and no free plan. Android is in closed alpha, and the iOS App Store listing is coming soon.
