# applayer.io > The AI app layer for business operations — deploy apps that automate support, sales, operations, and knowledge work across the stack you already run, with the governance to ship in the enterprise. applayer.io builds the application layer between foundation models and a company's existing systems of record. Instead of asking teams to stitch together LLMs, vector stores, and API connectors, applayer ships a control plane with native integrations, deterministic guardrails, model routing, and audit logging — so businesses can deploy AI apps to production without becoming an infrastructure team. ## Pages - [Home](/): Outcome-first overview of the platform, proof metrics, function pillars, and the final CTA to book a workflow audit. - [Platform](/platform): The five-layer architecture — integrations, data and knowledge, reasoning and agents, governance and FinOps, and the model layer — plus deployment options. - [Use Cases](/use-cases): Browse AI apps by function (support, voice, sales, operations, finance, knowledge, governance) or by industry (financial services, healthcare, logistics, field services, professional services, SaaS). - [Trust & Security](/trust): Security controls, shared responsibility model, data handling, encryption, audit, and deployment options for regulated environments. - [Company](/company): Mission, principles, and positioning behind the app-layer thesis. - [Book a workflow audit](/contact): Contact form to request a 45-minute workflow audit with the applayer solutions team. ## Optional - [Email preview](/lovable/email/transactional/preview): Internal endpoint used by the Lovable platform to render transactional email templates.
