The AI product manager for your entire team
Turn a sentence, transcript, or notes into a real PRD grounded in your Notion, Linear, GitHub, and Granola context.
A CPO-level review scores each document on strategy, structure, clarity, and completeness, then offers line-level edits you can accept in one click.
Build a clickable prototype straight from a spec, refine elements by pointing, and share a link the same day—or open in v0, Lovable, Bolt, or Cursor.
Pull context from docs, tickets, code, and meetings, then push finished work to Google Docs, Notion, Confluence, Linear, Jira, Slack, 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.
