Dropstone vs Superhuman Go: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Dropstone and Superhuman Go — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
Dropstone
Blankline
Self-hosted AI agent with long-term memory that spans CLI, chat, SDK and real-world actions, running on open-weight models you host.
Key features
- Persistent Cross-Surface Memory: Teach the agent something once in the CLI and it already knows it in chat, in the SDK and on a phone call — memory persists per user across sessions and surfaces instead of dying with one login.
- Self-Hosted Open-Weight Stack: Run the entire agent inside your own walls on your keys, machines and network, using open weights the company hosts or local models through Ollama, so source code never leaves your infrastructure.
- Proactive Background Operation: The agent is already running rather than waiting to be opened — it monitors what you asked it to watch and hands back only the decision that was actually yours.
- Approval-Gated Real-World Actions: Control smart-home devices, monitor an inbox around the clock, place phone calls and look up half-remembered contacts, with every action gated behind an explicit approval.
- 1M-Token Context on Every Tier: A one-million-token context window is included even on the free plan, letting the agent hold an entire repository in mind at once.
- Model-Agnostic Tiering: Dropstone Fast, Pro and Heavy each run whatever tops the open-weight leaderboards that month rather than being tied to a single lab.
- Learned Skills: The agent picks up skills it does not yet have, retains them and reuses them without being asked twice, with the skill list growing month over month.
- Multi-Surface Access: Reach the same agent through the Dropstone CLI, a web dashboard, VS Code / Cursor / Windsurf extensions and Remote MCP connectors, with sandboxed code execution and plan mode before changes apply.
Best for
- Air-Gapped Engineering Teams: Ship real code with an AI agent while keeping the models, the repository and the network entirely inside company infrastructure.
- Always-On Inbox Triage: Let the agent watch an inbox around the clock and surface or act on the messages that matter instead of checking it yourself.
- Terminal-Native Development: Use the CLI agent to generate code, run it in a sandbox and open diffs, with plan mode and approval gates before anything is applied.
- Personal Operations Automation: Hand off recurring real-world tasks — smart-home control, placing a call, chasing a contact — to an agent that already has your context.
- Cost-Sensitive Heavy Usage: Get several times more weekly coding usage per dollar than subscription coding CLIs by running on self-hosted open-weight models.
- Custom Agent Integration: Embed the same memory-backed agent into your own stack through the SDK and Remote MCP connectors.
Superhuman Go
Superhuman
Proactive AI assistant and agent platform that works inline across apps, sorting email, briefing you in Slack and improving your writing everywhere.
Key features
- Proactive Inline Suggestions: Annotates text in real time wherever you write, pointing out where you could be clearer, more convincing or factually wrong without needing a prompt.
- Email Assistant Agent: Sorts incoming mail, clears clutter, follows up and pre-drafts replies in your voice using context from your calendar and connected apps, powered by Superhuman Mail.
- Customizable Grammarly Agent: Built-in Grammarly writing intelligence that learns which underlines you find useful and adjusts its feedback accordingly.
- Knowledge Checker and Daily Brief: A background researcher that searches your data sources for evidence behind claims, plus a daily report surfacing Salesforce deals, Jira tickets, tasks and meetings needing attention.
- MCP Connectors: Connects to Gmail, Outlook, Calendar, Slack, Jira, Linear, Asana, Confluence, Zendesk, Salesforce, HubSpot, Workday, ServiceNow and more via pre-built or custom MCP connectors.
- Custom Agents and Agent Store: Build agents that trigger as you type, on a schedule or after events like a meeting ending, or add ready-made agents from Superhuman and partners.
- Many Surfaces: Works as inline underlines, a context-aware side chat, cursor actions on highlighted text, a Slack teammate you can @-mention, and a standalone Go app across desktop, browser and mobile.
Best for
- Inbox Triage: Letting Go sort email and draft replies each morning so you respond in a fraction of the time.
- Meeting Prep and Follow-Through: Crowdsourcing agendas before team syncs and auto-assigning tasks when meetings end.
- Live Call Support: Pulling key insights from a report in the side panel while answering unexpected questions on a partner call.
- Fact-Checked Writing: Drafting documents with inline suggestions and the Knowledge Checker verifying claims against company data.
- Project Tracking: Asking Go to build and maintain a team project tracker from connected tools like Jira or Asana.
- Team Q&A in Slack: At-mentioning Go in a channel for quick answers or tasks grounded in connected knowledge.
