KB2B

KB2B is an AI powered knowledge management platform built for fast growing SaaS companies and digital consultancies. Unlike traditional tools that simply store and index static content, KB2B reasons over dynamic, multi source information, meetings, documents, and AI led interviews, turning scattered inputs into verified, connected company knowledge. Every fact extracted from a meeting, a document, or a structured AI interview receives a POT Score, an explicit certainty rating from 0.0 to 1.0. Contradictions between sources are detected automatically instead of quietly coexisting, and every fact is linked to related facts through a live knowledge graph, showing how decisions, risks, and context connect across the organization. Scout, KB2B's first AI agent, answers questions by reading the most relevant facts in the knowledge base, gathering external context when needed, and returning insights with visible confidence scores and traceable citations back to the original source, meeting, document, or interview. There is no black box, every answer can be verified. KB2B captures knowledge from three sources: meeting recordings across Zoom, Google Meet, and Microsoft Teams, or imported transcripts from Granola, Otter, and Fireflies, any document format including PDF, Word, Excel, PowerPoint, and Markdown, and structured AI led interviews for brainstorming, retrospectives, and problem solving. Built on SciPot, a memory infrastructure layer purpose built for AI agents, KB2B is designed for teams where decisions and context change weekly, not once a quarter, roles like Chief of Staff, Head of Operations, and Head of Product at scaling companies. Available as a desktop app for macOS and Windows, and as a web application. Plans range from Spark to Megamind, all include a 7 day free trial.

Kernal by Andes

Kernal by Andes turns AI-assisted work into a structured record your team owns, can inspect and can move. It is built for people who use ChatGPT and other AI interfaces for decisions, research, planning, sales and operations, but need the useful knowledge to survive beyond a chat thread. A conversation is more than a transcript. It contains people, organisations, projects, systems, deals, goals, decisions and commitments. Kernal reconstructs those elements as a proposed knowledge graph, connects them to their source material and lets users review proposed changes before they become part of the record. Teams can correct relationships, preserve decision context and export the accumulated record instead of rebuilding it when tools or providers change. Kernal combines graph memory, source-backed records, hybrid retrieval and a visual workspace. Teams can search across sources, wiki pages, memories, actions, people, organisations, deals, goals and projects from one place. The managed product includes source ingestion, multi-pass synthesis, deal and goal boards, project and systems registers, review workflows and composed views generated from real graph data. Kernal is designed for high-context work: founders, consultants, researchers, commercial teams and operators who need their AI to understand more than the latest prompt. Kernal does not replace human judgement. It proposes structure, and people decide what to keep. Each record keeps its source path and review state visible, so a colleague can see what was observed, what Kernal proposed and what a person accepted. This supports continuity, handovers and accountable AI-assisted work without pretending the software made the decision. Managed Kernal runs in AWS Europe. Andes has joined the AWS Partner Network Software Path. For managed deployments, onboarding and support, contact explore@andes.no.
