Okibi AI
Okibi is a no-code web platform that empowers users to build and deploy AI agents simply by describing what they need in plain language. Instead of writing boilerplate code, managing integrations, or orchestrating multiple services manually, you use natural language prompts to define the agent’s behavior. Okibi takes care of constructing the architecture, handling browser automation, conditional logic, human-in-the-loop interaction, tool calling, and initial evaluations automatically behind the scenes. The platform offers a visual templates gallery to help users get started quickly as well as a chat interface where you refine or iterate on your agent’s design. It’s built for speed and accessibility so that non-technical users, teams with limited engineering bandwidth, or product builders can create internal automations for prospect qualification, invoice generation, meeting prep, content workflows, or similar agentic tasks without hiring devs.

Notis AI
Notis AI is a voice-first productivity assistant that integrates deeply with Notion and messaging apps like WhatsApp, Telegram, email or Raycast to let you dictate, capture, and organize notes, memos, tasks, meeting minutes, and more — all from wherever you are, without opening Notion explicitly. You can send a voice message, forward an email, text, or snap a photo, and Notis transcribes or processes the content (including for multiple languages), structures it into Notion databases, extracts action items, generates summaries, and even sends follow-ups or reminders automatically. It supports both disposable workflows (quick one-off tasks like summarizing a meeting or drafting an email) and persistent automation workflows (where Notis monitors databases, runs scheduled prompts, or responds to triggers so it behaves like an “agent” in your workspace).
