What is Superhuman?
Superhuman is becoming an email agent, not an email client
Superhuman has spent the last two months turning the inbox into an agent surface: an MCP server, a Codex plugin with prebuilt skills, Draft Sync so external assistants can write into Gmail and Outlook, and now Auto Drafts that pre-write a reply to every message that needs one. The rest of the roadmap — Android calendar, multi-day iOS views, notification quick-reply — is parity work running underneath the AI push.
What is Bandwidth?
Bandwidth methodically fills in global PSTN replacement while sharpening messaging reliability.
Bandwidth is executing a steady CPaaS expansion on two fronts: completing full PSTN-replacement coverage country by country (Brazil, Mexico, South Korea) and hardening its messaging stack with better delivery visibility and 10DLC registration tooling. The cadence is incremental and infrastructure-focused rather than headline features.

Superhuman is becoming an email agent, not an email client
◆ Current state
Superhuman has spent the last two months turning the inbox into an agent surface: an MCP server, a Codex plugin with prebuilt skills, Draft Sync so external assistants can write into Gmail and Outlook, and now Auto Drafts that pre-write a reply to every message that needs one. The rest of the roadmap — Android calendar, multi-day iOS views, notification quick-reply — is parity work running underneath the AI push.
◆ Where it's heading
The direction is to reduce the human to an editor. Auto Drafts already claims 60% of replies sent unedited and pulls context from calendar and the web, while the MCP surface lets any agent triage, draft, and schedule. Expect the mobile and calendar catch-up to continue while the AI layer absorbs more of the reply workflow.
◆ Prediction
Next likely move is wiring Auto Drafts into more tools — the changelog already promises Slack, CRM, and meeting-notes context — pushing toward send-ready replies drawn from a user's whole stack.
Bandwidth
5.0COMMS
Bandwidth methodically fills in global PSTN replacement while sharpening messaging reliability.
◆ Current state
Bandwidth is executing a steady CPaaS expansion on two fronts: completing full PSTN-replacement coverage country by country (Brazil, Mexico, South Korea) and hardening its messaging stack with better delivery visibility and 10DLC registration tooling. The cadence is incremental and infrastructure-focused rather than headline features.
◆ Where it's heading
The clear arc is Bandwidth positioning as a global carrier-replacement layer: each country note closes emergency and outbound gaps toward complete PSTN parity, while messaging work (delivery callbacks, longer receipt windows, Registration Center) targets enterprise reliability and US/Canada compliance. Advanced routing and number-intelligence releases round out the enterprise voice toolkit.
◆ Prediction
Expect more country coverage notes marching toward global PSTN replacement, and continued 10DLC Registration Center buildout, likely graduating the registration API from early access to general availability.
