Spark Launches AI Assistant, Ushering in a New Era of Personalized Productivity
Nov 11, 2025
Spark, the award‑winning email app used by more than 19 million people worldwide, today announced the launch of its AI Assistant — part of the Spark +AI offering. AI Assistant acts as a personal productivity partner, helping busy individuals find, summarize, and act on anything in their inbox.
Email remains the world’s most enduring medium for meaningful communication. Historically, it’s where key decisions happen. But, with the average worker receiving 117 emails each day, it’s actually where momentum stalls.
Spark is changing that with its AI Assistant, a personal assistant that sits across all your email accounts to help you find what you need, summarize conversations into concrete steps, and be more decisive in your inbox.
Human‑Centered Productivity, Enhanced by AI
The latest wave of email startups favor a triage-based mentality (review, decide, organize), forcing people to compromise how they work.
Spark takes the opposite approach, using AI to make tools more human‑centered and adaptive—reducing repetitive tasks, surfacing what’s important, and turning intent into action so people can stay focused on outcomes, not busywork.
AI Assistant is the first in a series of AI‑enhanced features rolling out over the coming months.
Introducing the AI Assistant: Find, Summarize, and Act on Anything in Spark
Spark’s AI Assistant empowers anyone managing a high volume of emails to be more effective. Unlike other options on the market, it works across a unified inbox and multiple email providers, including Google, Microsoft, Yahoo, iCloud, and IMAP. That means it can surface the right information, regardless of the account it came from.
As of launch, AI Assistant can:
• Find information and cite sources: Ask natural‑language questions (e.g., “When is my flight to Paris?”), and the assistant searches across emails, text attachments, calendar events, and meeting notes to deliver accurate answers with links to the original source.
Examples:
- When is my flight to Rome?”
- “What’s the deadline for signing this contract?”
• Summarize and synthesize complex topics: The assistant understands intent, distills long threads into action items, identifies priorities, and clarifies key asks — so users spend time on what matters most.
Examples:
- “List action items from my meeting notes with Tom.”
- “Explain what ‘handover process’ means in this context.”
• Draft, proofread, and revise emails: All Spark +AI writing tools are available via the assistant to help craft professional‑quality emails — drafting, rephrasing, proofreading, and translating — while learning your preferences so messages sound uniquely you.
Examples:
- “Draft an email to John summarizing the next steps on our product launch.”
- “Rewrite this email to sound more enthusiastic.”
• Manage your inbox and calendar. Organize your inbox and calendar through a conversational interface. Check colleague availability, schedule events, archive or unsubscribe from emails, prioritize messages from select senders, set reminders, and more.
Examples:
-“Archive all read newsletters from last month.”
- “Move all receipts from Uber to my Expenses folder.”
“For more than a decade, we’ve focused on the craft of making email feel human, lovable, and efficient,” says Alex Tyagulsky, Co‑founder and Head of Spark. “AI Assistant builds on that foundation — transforming Spark into a partner that helps people move work forward by finding what matters, eliminating noise, and turning intent into action.”
AI Assistant is available today for all Spark users, with usage limits set by plan.
Like all of Spark +AI, AI Assistant is opt-in. Once enabled, it creates a private, local index of emails and meeting notes. When a user asks a question, the assistant searches local data to find the most relevant information, then securely sends the prompt and most relevant emails to Spark’s trusted AI provider in order to generate a response. No data is used for training, and prompts and emails are not shared with Spark.
New Pricing Plans to Unify Individual and Team Offerings
As part of this launch, Spark is updating its paid offerings to better serve individuals and teams. Spark’s Free plan continues to help people manage multiple email accounts, offering a Smart Inbox, cross-device sync, and AI Assistant (up to one month of email history).
Spark Plus replaces Spark Premium and includes enhanced productivity features like Priority and Gatekeeper, integrations (e.g., Things, Notion, Asana), 40 AI meeting notes per month, and extended access to AI Assistant (one year of email history).
Spark Pro is a new premium tier for advanced automation and collaboration needs. In addition to Spark Plus features, Spark Pro will offer unlimited history for AI Assistant, custom AI Actions (reusable prompts for drafting and summarizing emails, coming in Q4), AI email rules (coming in Q4), unlimited AI meeting notes, read statuses, and shared inboxes.
Spark Plus costs $10 per user per month when billed monthly. Spark Pro costs $20 per user per month when billed monthly. To learn more about Spark and sign up for a 7-day free trial, visit www.sparkmailapp.com or download it directly from the App Store, Google Play, or the Microsoft Store.
