Gemini vs Superhuman
Gemini scores 74 to Superhuman's 19 on public evidence for email writing & inbox management, and they rank #1 and #4 there. Only Gemini has a free tier. Numbers below are the same public signals the ranking uses, recomputed nightly — nothing here is sponsored.
Gemini
Google's assistant with Deep Research reports, Gmail/Docs/Drive integration and YouTube video understanding.
+ Deep Research produces long cited reports from dozens of sources, and it reads your Gmail, Drive and Calendar directly when you allow it.
− Quality swings between Flash and Pro models, and it refuses or hedges on some topics more than competitors.
Superhuman
A keyboard-driven email client for Gmail and Outlook with AI drafting in your voice, inbox triage and auto-summaries.
+ Write with AI learns your sent mail and produces replies that sound like you, and Auto Summarize puts a one-line gist atop every thread.
− Expensive for an email client, and it only works on Gmail and Microsoft 365 accounts.
