HireVue

n8n is a workflow automation platform for building AI agents and connecting your apps and data. It combines a visual drag-and-drop editor with the option to drop in custom JavaScript or Python where you need it, and can run self-hosted or in n8n's cloud. It ships with 400+ pre-built integrations plus native LangChain-based AI nodes for building multi-step agents.

Manus is an autonomous AI agent that takes a task like researching a topic, building a spreadsheet, or writing code, and works through it on its own, browsing the web and running tools as needed, then hands back a finished result. It's less a chatbot and more a virtual assistant you assign work to. It runs on a credit system, so cost tracks how much work each task actually takes rather than a flat seat price.

Toyo is an AI agent built for non-technical founders and small teams who need an executive assistant but can't hire one. It runs on a cloud computer with browser and app access, so it can triage your inbox, prep you for meetings, research prospects, and draft outreach, all through a normal text or voice conversation. There's no dashboard to learn; you just message it like you would a real assistant, and it asks for your approval before taking any action outside its sandbox.

Sim is an open-source platform for building, deploying, and managing AI agents that automate work across your other tools. You design workflows on a visual canvas, connect them to 1,000+ integrations like Slack, HubSpot, and Notion, and run them with any major LLM provider. It's aimed at technical teams, not casual users, though the visual builder keeps it from feeling like pure code.

Badge is a professional verification app that gets an AI agent to reach out to your former colleagues on WhatsApp and ask them a few short questions about your work. Those anonymous answers roll up into a "Trust Score" you can share with recruiters instead of, or alongside, a resume. It's aimed at job seekers and freelancers who want proof of how they actually worked, not just a list of job titles.

Katalyst listens to your calls, emails, and calendar, then writes the updates back into Salesforce itself: summaries, field changes, follow-ups, and next steps. It's built for enterprise sales teams drowning in CRM admin, not for solo founders or non-Salesforce shops. It's brand new (launched July 2026), so the pitch is strong but the track record is not.
