In their own words
Google Slides
Google Slides is a browser-based presentation tool for creating and delivering presentations without installation. Anyone with a Google Account can create slides, and the service runs on the web, Android, and iOS. Users can start with templates and add videos, animations, transitions, GIFs, and stickers. Gemini in Slides can summarize content, generate slides from prompts and Drive content, and create images. Collaborators can edit live, comment, use live pointers, and control who can view, comment on, or edit a presentation. Slides can also be accessed, created, and edited offline. It can import or directly edit Microsoft PowerPoint presentations and import Canva presentations online. Users can present through Google Meet, add speaker spotlight, or record presentations on some Workspace plans. Google offers a free plan; paid plans start at $7/user/mo, with a 14-day trial. Some capabilities require a Workspace plan or add-on. Google says Slides data is encrypted by default and describes additional security and privacy controls.
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.
