TeamBrain

TeamBrain is a team knowledge management and project collaboration platform that enables teams and AI tools to access, contribute to, and organize shared documentation, tasks, and decisions from a single centralized workspace. The platform is built on plain markdown files, which allows AI tools that support the Model Context Protocol (MCP), including Claude and ChatGPT, to connect directly to the same workspace used by human team members. This means AI assistants can read from and write to the same knowledge base without requiring separate integrations or manual context-sharing between tools and people. TeamBrain is designed for teams that rely on a combination of human collaborators and AI tools, where institutional knowledge, project decisions, and task context frequently get distributed across chat threads, shared drives, and individual team members rather than stored in one accessible location. Key features and capabilities include: - Decision Log: Every change in project direction is recorded alongside the reasoning behind it, not just the outcome. This allows new team members, contractors, or connected AI tools to understand the context and rationale of ongoing work without requiring a handoff or explanation. - Built-in Project Management: Includes a Kanban board, calendar, comments, and asset storage to cover core task and workflow management within the same workspace. - MCP Integration: Any AI tool that supports the Model Context Protocol can connect directly to TeamBrain, enabling AI assistants to pull relevant context or add structured information to the shared workspace. - Markdown-based Architecture: All content is stored in plain markdown files, keeping the workspace portable, readable, and compatible with a wide range of tools and workflows. - Centralized Knowledge Base: Documentation, task history, project assets, and decisions are stored together, reducing the time team members or AI tools spend locating context before starting work. TeamBrain is suited for small to medium-sized teams working with distributed contributors, virtual assistants, freelancers, or AI-assisted workflows where continuity of context across participants is a recurring operational challenge.

Wartable

WarTable is a browser-based workspace that combines a business dashboard, a document knowledge base, and an AI operator that can act on your connected accounts. You start by connecting your existing tools (Gmail, Slack, Trello, Google Drive, and others) and uploading your company documents into searchable knowledge bases. From there you work mainly through chat with Athena, the built-in AI operator. Because she reads from your uploaded files, your workspace memory, and live data from your connected accounts, her answers reference your actual clients, projects and numbers rather than generic information. She can also execute: send an email, post to a channel, create or update a card, generate a report, run Python for analysis, or produce an image. Alongside chat, the workspace includes: Command Center, a dashboard showing headline metrics, an action queue of items needing attention, recent activity across connected tools, a daily briefing, and AI usage and spend. Knowledge Bases, upload documents or pull them from cloud storage; they become retrievable context for every future conversation. Notes, a folder-organised notes system Athena can read from and write to. Automations, scheduled routines that run on a cron schedule, plus multi-step workflows, each with run history and error reporting. Business Health Index, a structured evaluation that scores five areas of the business (Operations, Growth, Organization, Technology, Governance), breaks each into component systems with evidence and gaps, and generates prioritised actions you can then work through in chat. Storage, a workspace file library that doubles as the source for knowledge bases. WarTable is aimed at agencies, consultancies and service businesses where one or two people are effectively the connective tissue between every tool the company runs on.
