Unlike a traditional bot that follows fixed rules, an agent can make decisions, use\u00a0context\u00a0and choose the right tools for the job.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;335559738&quot;:240,&quot;335559739&quot;:240}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">For example, an AI agent can:<\/span><span data-ccp-props=\"{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;335559738&quot;:240,&quot;335559739&quot;:240}\">\u00a0<\/span><\/p>\n<ul>\n<li><span data-contrast=\"auto\"> Pull customer data from your CRM<\/span><\/li>\n<li><span data-contrast=\"auto\">Analyse the information<\/span><\/li>\n<li><span data-contrast=\"auto\">Generate a personalised email<\/span><\/li>\n<li><span data-contrast=\"auto\">Log the communication<\/span><\/li>\n<li><span data-contrast=\"auto\">Trigger a follow up task<\/span><\/li>\n<li><span data-contrast=\"auto\">Notify the account manager<\/span><span data-ccp-props=\"{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;335559738&quot;:240,&quot;335559739&quot;:240}\">\u00a0<\/span><\/li>\n<\/ul>\n<p><span data-contrast=\"auto\">Rather than treating each step as a separate workflow, the agent handles the full process from end to end.
