What should journalists know about Superhuman?

Superhuman is genuinely fast. The keyboard-driven interface, split inbox, and AI triage cut email processing time measurably — the company claims 4 hours saved per week, and power users confirm it feels significantly faster than Gmail's web interface. The AI features (auto-drafting replies, summarizing threads, scheduling optimization) work well for routine correspondence. The journalism-specific concern: all email flows through Superhuman's servers. They process your messages to power AI features, search indexing, and delivery optimization. For most beat reporters, this is an acceptable tradeoff — your email is already on Google or Microsoft servers. For investigative journalists communicating with sensitive sources via email, adding a third-party processor to the chain increases exposure. Superhuman Platform Inc acquired Grammarly's parent company in 2024, consolidating two AI writing tools under one roof. The combined entity processes a significant volume of professional communications.

Best for

High-volume email management. Fast triage of PR pitches and source correspondence. AI-assisted reply drafting for routine emails. Reporters who use keyboard shortcuts and want speed over features.

Not for

Journalists on tight budgets — $30/month is steep for an email client. Investigative reporters communicating with sensitive sources via email (adds a third-party processor). Anyone who needs to keep email processing within a single jurisdiction. Users who want offline access — Superhuman requires an internet connection.

Privacy policy summary

Superhuman accesses and processes your email to provide AI features, search, and delivery tracking. They store email metadata and content on their servers. Read receipts (tracking pixels) are on by default — disable them in settings. The company states they do not sell personal data. AI features process email content through their models. After the Grammarly acquisition, the combined privacy footprint is larger.

How to protect yourself:

Disable read receipts (tracking pixels) immediately — they are on by default and reveal when and where recipients open your emails. Do not use Superhuman for email threads involving confidential sources — use Signal or encrypted email instead. Review which Gmail/Outlook permissions Superhuman requests and revoke if you stop using the service. Be aware that AI-suggested replies are generated from your email content processed on Superhuman's servers.

Standard cloud email client security — TLS in transit, encrypted at rest, SOC 2 compliant. The concern is not a security flaw but an expanded data surface: your email now flows through both your provider and Superhuman's servers. Read receipts enabled by default are a privacy issue for journalists. Adequate for general newsroom use. Not recommended for source communication on sensitive investigations.

Who Owns This

Owner Superhuman Platform Inc (CEO Rahul Vohra). Acquired Grammarly's parent company in 2024.
Funding Venture-backed. Raised $108M+ including $75M Series C (2021) led by IVP and a16z. Post-Grammarly acquisition, the combined entity is one of the largest AI writing/communication companies.
Business model Subscription SaaS. $30/month per user. Team and enterprise pricing. No free tier — revenue comes entirely from subscriptions.

Known issues

Read receipts (tracking pixels) enabled by default — journalists should disable these immediately to avoid revealing their location and reading habits to PR contacts and sources. All email processed through Superhuman's servers in addition to your email provider, expanding the data-access surface. The Grammarly acquisition raised questions about data consolidation across two products that process sensitive professional communications. No end-to-end encryption — Superhuman can read your email content (as can your email provider). Price increased from $25 to $30/month in 2025.

Pricing

$30/month per user. No free tier. 14-day free trial. Team and enterprise plans available.
