In their own words
arg.ai
arg.ai is a shared workspace for teams and AI agents, organized around files that persist across sessions and are indexed for search and agent context. Its workspace agent can read and write files, run Python and Bash in an isolated sandbox, and generate media files. Users can build internal apps connected to workspace files, data, agents and integrations. Automations can run on schedules, file changes or webhooks, saving results back into the workspace. Listed connectors include Linear, Notion, Sentry, PostHog, Apollo.io, Pylon, Granola, Canva, Ashby and Relevance AI, with MCP server support and more than 100 typed actions and triggers across 17 providers. The service describes SAML and OIDC sign-on, directory sync, custom roles, service accounts, selected-region storage, versioned files and an append-only audit log. The desktop app works offline with files on the user’s machine. Free includes 1 GB storage and API access. Team costs $10 a month with annual billing; monthly billing is $12/user/month.
OpenCharts
OpenCharts is an AI workspace for flowcharts, presentations, notes, code, video, and agents. Theo AI can create these materials from plain-language descriptions. Flowcharts use terminal, process, decision, and data nodes on an infinite canvas, with automatic layout and export tools. The presentation editor supports editable slides, speaker notes, transitions, AI generation, rehearsal coaching, web publishing, and PPTX export. Theo Agents can start on schedules, webhooks, monitoring triggers, or manually; they can use external connectors, human approval gates, and produce deliverables. Connectors include Stripe, HubSpot, Slack, Google Sheets, Discord, Notion, GitHub, and others. A REST API manages project types, and the Theo MCP server provides 113 tools and five readable resources. Each account starts with 10 GB of Drive storage, including Free Forever. That plan costs nothing and includes 500K AI credits and one of each project type. Starter costs $9.99 a month, Pro $24.99 a month, and Teams $14.99 a month with a three-user minimum. OpenCharts says it does not use customer data to train or fine-tune AI models.
