ShogunAI vs Sim: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of ShogunAI and Sim — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
ShogunAI
ShogunAI
A local-first macOS memory and execution assistant that remembers your workday on-device and finishes work inside the tools you already use.
Key features
- On-Device Memory Layer: Captures mail, meetings, documents and screen context locally and indexes them into an encrypted store on your Mac, with no cloud copy by default.
- Contextual Recall with Sources: Answers plain-language questions across Mail, chat, docs and calendar from a single search, attaching the source and timestamp to every hit so answers can be checked.
- Execution Layer with Three Autonomy Levels: Reversible work runs automatically, drafts wait for review, and anything leaving your Mac stops for explicit approval — with every action logged as what ran, on what evidence, and what left the device.
- Inline Draft at the Caret: Press Option and ShogunAI reads the field around your cursor plus the memory behind it, then writes the continuation directly in the app you are already typing in as a local write you send yourself.
- Meeting Minutes, Not Recordings: Transcribes a meeting as it starts and on completion writes a summary, the decisions made and the commitments it heard, filing next actions into your work state with one tap; audio is never written to disk.
- Two-Way Live Translation: Set the language you speak and the language they speak — their speech reaches you in yours and yours reaches them in theirs, with only text retained afterwards.
- Daily Brief: Assembles what moved overnight, what is still open and what you promised someone before the day starts, rather than on request.
- Shared Memory Across Models and Agents: The same structured state of people, projects, commitments and open loops reaches Claude, Cursor, ChatGPT and anything driven over MCP, CLI or REST, so no session starts cold.
Best for
- Eliminating Cold Starts: Stop re-pasting last week's decisions and open threads at the beginning of every model session — every assistant starts from the same live memory of your work.
- Closing Open Loops: Surface the follow-up that is due today, draft the reply with the correct file attached, and hold it for approval before it reaches the recipient.
- Meeting Follow-Through: Turn a call into decisions, commitments and filed next actions automatically instead of re-listening to a recording.
- Answering 'What Did We Decide?': Recall a specific decision from a Notion brief or Gmail thread weeks later, with the source and time attached so it can be verified.
- Privacy-Constrained Work: Run an assistant over sensitive client or company context on machines where a cloud-indexed copy of the workday is not acceptable.
- Cross-Language Collaboration: Hold live meetings with counterparts in another language and keep only the translated text afterwards.
- Consultant and Founder Context Switching: Keep separate projects, people and commitments straight across many concurrent engagements without manual note discipline.
Sim
Sim
Open-source AI workspace to build, deploy and manage AI agents across 1,000+ integrations from one platform.
Key features
- Visual Agent Builder: Drag-and-drop canvas for wiring prompts, tools, memory and LLM calls into deployable agents.
- 1,000+ Integrations: Ready-made connectors to CRM, sales, support, dev and productivity tools so agents can act across a company's stack.
- Multi-model Support: Route each step to the best model from every major LLM provider (OpenAI, Anthropic, Google, open-weights).
- Runtime & Scheduling: Deploy agents as scheduled jobs, webhooks or API endpoints with retries and error handling.
- Team Workspace: Shared library of prompts, tools and agents with role-based access so teams reuse rather than rebuild.
- Open Source & Self-Hostable: Full source available so security-sensitive teams can run Sim in their own cloud.
- Observability: Traces every agent run with inputs, tool calls and outputs so builders can debug and improve prompts.
Best for
- Sales operations: Build agents that enrich inbound leads, sync them into the CRM and hand them to reps.
- Customer support: Deploy triage agents that read tickets, pull knowledge-base answers, and draft or send replies.
- Internal automations: Wire agents into Slack, Google Workspace or Notion to automate reports, briefs and reminders.
- Data workflows: Chain LLM steps with API tools to summarize dashboards, clean CSVs or extract structured data.
- Compliance-sensitive teams: Self-host Sim to keep prompts, tool credentials and traces inside the company's own cloud.
