OpenCharts vs Slides

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.

Slides is a web presentation editor for creating, presenting and sharing decks, with AI tools that can draft content, rewrite text and refine visuals. Decks can be presented live, shared by link, exported, embedded or self-hosted. The service supports PowerPoint import and export, presenter mode, offline access, real-time collaboration, templates and brand kits. Free accounts can create public decks only. Paid customers get private decks by default, can change visibility, and can share private decks with a secret link or password; decks marked Internal are visible to team members and not others. Plan limits differ: Lite includes 1 GB of storage, one collaborator per deck and 50 AI credits monthly; Pro includes unlimited storage, three collaborators and 400 monthly AI credits; Team includes unlimited deck collaborators and 400 credits per user monthly. Team also supports SSO with Okta, Microsoft, Google and more. Developers can use a REST API, MCP server, and full HTML and CSS access. Listed integrations include Dropbox, Google Analytics, Google Maps, Google Forms, YouTube and Markdown. It runs in a modern browser and requires an internet connection. Free costs nothing; Lite is $5 a month billed annually, with monthly billing also available.
