🦸 Grammarly acquires Superhuman!

Grammarly announced its acquisition of Superhuman, a popular AI-native email client, as part of a strategic push to enhance its productivity suite and accelerate its vision of an AI-driven workspace. The financial terms of the deal were not disclosed.

Here's a breakdown of the key details:

🤝 Why Grammarly Acquired Superhuman: Grammarly’s vision is to build an "AI-native productivity suite," a future where AI agents collaborate seamlessly within everyday workflows. Superhuman significantly advances this vision by integrating deeply into one of the most critical professional tools: email.

📌 What Superhuman Brings to Grammarly: Founded by Rahul Vohra, Vivek Sodera, and Conrad Irwin, Superhuman built a powerful productivity-focused email client, raising more than $114 million from leading investors such as a16z, IVP, and Tiger Global at a valuation of $825 million.

Key highlights of Superhuman's offerings include:

• AI-driven inbox triage and organization

• Smart reply suggestions

• Integrated scheduling and calendar management

• Users save roughly 4 hours weekly and respond to emails 1–2 days faster.

With 94% of weekly active Superhuman users already embracing AI features, the integration aligns naturally with Grammarly's AI ambitions.

⚡ Strategic Vision and Future Outlook: Grammarly’s strategic objectives with this acquisition include:

• Leveraging Superhuman’s AI technology to further enhance Grammarly’s email assistance capabilities—already the number-one Grammarly use case.

• Accelerating the development of multiple collaborative AI agents that will handle tasks like scheduling, inbox triage, writing emails, and deep research.

• Combining forces to build an integrated productivity suite where AI agents can collaborate across applications, including email, calendars, and tasks.

💬 Executive Insights

🔍 Perplexity unveils new Max subscription tier.

AI startup Perplexity has unveiled its new hyper-premium subscription plan, Perplexity Max, priced at $200 per month. This tier targets power users seeking enhanced productivity and early access to cutting-edge AI features.

Here's everything you need to know:

📌 What’s Included in Perplexity Max? Subscribers to Perplexity Max receive:

• Unlimited access to Perplexity Labs (the AI-powered spreadsheet and report-generation tool)

• Early access to the forthcoming AI-powered browser, Comet

• Priority access to services powered by frontier models:
  

  • OpenAI’s o3-pro

  • Anthropic’s Claude Opus 4

📈 Business Context & Market Strategy: Perplexity generated ~$34 million in revenue in 2024, driven primarily by its $20/month Pro subscription. The company burned around $65 million in cash in the same period, largely due to cloud infrastructure costs and buying AI model access from OpenAI and Anthropic.

Annual recurring revenue (ARR) reportedly rose to ~$80 million by early 2025. Perplexity recently sought to raise $500 million at a valuation of ~$14 billion, highlighting its aggressive growth trajectory.

🥊 Competitive Landscape: The introduction of Perplexity Max comes as other major AI players are releasing hyper-premium plans to monetize power users, including:

• OpenAI: ChatGPT Pro ($200/month)

• Anthropic & Google: premium AI subscription tiers

• Cursor: AI-focused coding and productivity services

Meanwhile, major players are pushing competitive AI-powered search products:

• Google: Heavily promoting its AI-powered AI Mode

• OpenAI: Deepening search integration into ChatGPT and potentially developing its own browser.

Perplexity’s success depends heavily on maintaining competitive advantages in AI search, despite relying on third-party AI model providers. In addition, by leveraging premium subscribers (Max tier) to offset high operating costs, the company can potentially stay ahead of rivals.

🤖 Apple’s Siri might be powered by OpenAI!

 Apple is reportedly in discussions to leverage OpenAI or Anthropic's technology to enhance its struggling AI-upgraded Siri, according to Bloomberg's Mark Gurman.

Here’s a summary of the situation:

📌 Why Apple Might Partner with OpenAI or Anthropic: Apple has been experiencing significant challenges in developing its upgraded Large Language Model (LLM)-based Siri, resulting in delayed launches and leadership reshuffles. CEO Tim Cook previously “lost confidence” in former AI lead John Giannandrea, and subsequently appointed Mike Rockwell, head of Apple’s Vision Pro, to oversee AI and Siri efforts.

With internal progress lagging, Apple has reportedly approached external AI leaders—OpenAI and Anthropic—to explore using their advanced large language models on Apple’s private cloud infrastructure.

📊 Internal Evaluations and Results: Rockwell instructed his team to evaluate several leading AI models to determine which performed best for handling basic user requests:

• Anthropic’s Claude (Reportedly the most promising so far)

• OpenAI’s ChatGPT

• Google’s Gemini

Apple executives previously considered acquiring AI startup Perplexity (already partnered with Motorola) to bolster Siri. 

🎙️ Current State of Apple’s AI Development: At the recent Worldwide Developers Conference (WWDC 2025), the much-anticipated upgraded Siri was notably missing. Apple’s SVP of Worldwide Marketing, Greg Joswiak, acknowledged the technology simply "didn’t hit our quality standard."

The company remains undecided on whether to integrate external models or continue refining its in-house solutions.

If Apple proceeds with this partnership, it would mark a significant shift in strategy and could substantially elevate Siri’s capabilities, positioning Apple more competitively against other tech giants.
