What is Session?

Session pulls back from a funding crisis as community support revives development

Session's recent feed is dominated by survival, not shipping: a cofounder's personal appeal warning the project might not continue, followed by news that community donations, node operation, and awareness restored its runway and development will resume. Underneath sits real roadmap work — Session Protocol V2 (forward secrecy, post-quantum crypto) and the long-running Session Pro Beta.

What is Superhuman?

Superhuman rebuilt its mobile apps and wired every inbox into AI assistants — the email client is becoming a suite.

Superhuman has evolved from a keyboard-shortcut email client into an AI-native communication platform covering email, calendar, and AI drafting agents — all gated on Business/Enterprise tiers. The mobile apps, long a weak point relative to desktop, received their first major overhaul in years with a redesigned navigation model and native iOS/Android aesthetics. MCP support with multi-account access is live, letting AI assistants like Claude and ChatGPT operate across all connected inboxes simultaneously. Calendar coverage now spans desktop, Android, and iOS with room booking and multi-day views.

Session pulls back from a funding crisis as community support revives development

◆ Current state

Session's recent feed is dominated by survival, not shipping: a cofounder's personal appeal warning the project might not continue, followed by news that community donations, node operation, and awareness restored its runway and development will resume. Underneath sits real roadmap work — Session Protocol V2 (forward secrecy, post-quantum crypto) and the long-running Session Pro Beta.

◆ Where it's heading

The product spent recent months in existential mode and has now stabilized enough to resume development and keep critical infrastructure running. The technical direction — post-quantum cryptography and forward secrecy in Protocol V2, plus Pro Beta features — remains the substance, but momentum hinges on the donation-funded model that just rescued it.

◆ Prediction

Expect development to resume around Protocol V2 and the Session Pro Beta, with continued reliance on community funding; pace depends on whether the donation rebound holds.

S6.3

Superhuman rebuilt its mobile apps and wired every inbox into AI assistants — the email client is becoming a suite.

◆ Current state

Superhuman has evolved from a keyboard-shortcut email client into an AI-native communication platform covering email, calendar, and AI drafting agents — all gated on Business/Enterprise tiers. The mobile apps, long a weak point relative to desktop, received their first major overhaul in years with a redesigned navigation model and native iOS/Android aesthetics. MCP support with multi-account access is live, letting AI assistants like Claude and ChatGPT operate across all connected inboxes simultaneously. Calendar coverage now spans desktop, Android, and iOS with room booking and multi-day views.

◆ Where it's heading

Superhuman is building toward a unified communication suite — the rebranded 'Superhuman Mail' name explicitly anticipates Mail, Docs, and Go as sibling products. The heavy investment in calendar (rooms, Android, multi-day iOS views) signals calendar parity with email as a near-term priority. AI drafting is moving toward full automation: Auto Drafts 2.0 already completes 60% of replies without editing, and the team has announced a voice mode and a rewritten email engine as the next milestones.

◆ Prediction

Voice mode and a rewritten email engine are both on the stated roadmap. The most likely next shipping moment is deeper tool integrations for Auto Drafts — Slack and meeting-notes context were specifically teased — which would close the gap between drafting and the rest of a user's work context.
