Smart, focused email with AI help — for individuals and teams
Spark's Smart Inbox and Priority highlight messages from important people and bundle newsletters and notifications so the rest of your inbox stays quiet.
An AI Assistant lets you find, summarize, and take action on anything in your inbox, while an AI writing assistant drafts emails and Auto-Drafts pre-writes replies.
Translate incoming messages, get instant summaries of long threads, and quickly grasp the point without reading every line.
Share drafts, leave private comments, delegate ownership, and track progress on email threads with your colleagues.

Map any parcel or draw custom boundaries, then generate a buildable plan with road layout, turning radii and topography handled so you avoid redesign later.
Produce optimal surface and structured parking layouts, set custom stalls and drive aisles, and validate parking ratios without manual drafting.
Overlay parcel, environmental and zoning data, model 3D terrain with cut-and-fill analysis, and check power and utilities infrastructure before design assumptions harden.
Connect financial models directly to your design, with live pro forma figures and import of your own Excel templates, to see whether a deal pencils.
