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.
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.
Bandwidth vs Superhuman: editorial side-by-side
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.
Superhuman
7.5COMMS
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.
