Nebula is your AI executive assistant — it connects your email and chat, uses AI to surface what actually needs your attention, and drafts replies based on your patterns.
Knowledge workers drown in notifications across email, Slack, Teams, and more. Context-switching kills deep work. Important messages get buried under noise.
Nebula brings together email and chat into a single intelligent interface — powered by AI that learns what matters to you.
Email and chat in one place. No more switching between Gmail, Slack, and Teams. Nebula gives you a single stream, organized by context — not by tool.
Nebula's AI learns your communication patterns. It separates what needs your attention from what can wait — so you always see the signal, never the noise.
Block distractions with Pomodoro-style focus sessions. Only truly urgent messages break through — everything else waits for your next review window.
Nebula generates AI-assisted drafts that mirror your sent-message style and respond to the full thread context. Nothing is used to train AI models — see our sub-processors page. Review, edit, send — in a fraction of the time.
Automatic engagement scoring for every contact. Know at a glance who matters most, who's new, and who's going cold — across all channels.
Your data, your control. Nebula stores and analyzes your messages to power filtering, prioritization, and AI summaries. We never sell your data. We never train our own models on your content, and we only use AI providers whose published terms commit to the same — see our sub-processors page for the current list.
No complicated setup. Connect your accounts, and Nebula starts working for you immediately.
Link your Gmail and chat tools with one click. Nebula uses secure OAuth — your credentials are never stored.
Within hours, the AI analyzes your communication graph — who you interact with, what's urgent, what's routine. No manual rules needed.
Your unified inbox shows the signal. Focus Mode protects your deep work. AI drafts handle the rest. Reclaim your day.
