In their own words
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.
Slaide
Slaide creates slide decks from plain-text .slaide files and renders them as web presentations, print-ready PDFs, or editable PowerPoint files. Its AI can plan a presentation’s story, choose a theme, write slides, and review its work while the user steers the process. You can also import PowerPoint or Keynote decks into editable .slaide files. Coach provides spoken, slide-by-slide rehearsal with timing and pace feedback, and can suggest a fix for a point missed on a slide. Decks can include incremental reveals, transitions, video, audio, sandboxed live embeds, and speaker notes. Slaide provides an Agent Skill and MCP server for agents to scaffold, validate, and render decks. Existing decks can be opened, edited, and presented offline in the iPhone and iPad app. Free Mac and Windows desktop apps can view, present, and export decks without an account or network connection. The Free plan is $0 forever and includes one cloud-AI deck of up to 10 slides; further cloud AI requires a Day Pass or Slaide Hosted plan.
