Arlo - 2026 Pricing, Features, Reviews & Alternatives

Arlo is a cloud-based AI chief of staff designed for founders and early-stage startup operators. It connects to email inboxes, calendars, and messaging channels including WhatsApp to filter low-priority communications, surface high-signal items requiring attention, and execute actions such as drafting replies, scheduling meetings, and sending follow-ups. Access is available through a web cockpit, WhatsApp briefings, and mobile.

Core functionality includes AI-powered email triage with drafted replies, a daily morning brief, calendar preparation with attendee context, automated follow-ups, and contact structuring. A memory and narrative engine extracts and maintains a profile of the user's relationships, projects, and priorities over time. A built-in vault supports bidirectional sync with Obsidian for persistent note and knowledge management.

AI inference runs on Cloudflare Workers AI infrastructure using the gpt-oss open-weights model family (OpenAI open-weights). Routine inference uses the 20B parameter variant; deeper reasoning uses the 120B variant. Email bodies are encrypted at rest, purged after 30 days, and never sent to third-party cloud models for training. Organizations are isolated cryptographically, making Arlo suited for founder-led businesses and technology startups where communication volume and data privacy are operational priorities.
