Decks.Studio vs OpenCharts

Decks.Studio turns a sentence, file, link, or voice note into an editable deck or A4 document. Users can refine a result by chatting with it and undo individual AI changes with one tap. Google Docs, Sheets, and Slides files can be imported and converted into an on-brand deck or document. Live Present lets an audience follow slides in a browser using a join code, without an app or account. Shared decks can be password-protected, configured to allow or block PDF downloads, and have access revoked immediately. Insights show who opened a deck, how long they stayed, and which slide held or lost attention. Exports include print-ready PDFs, editable PowerPoint decks, Word documents, live links, and narrated MP4 video with an AI voiceover. E-signatures use an individual signing link and produce a signed PDF with a tamper-proof audit trail. The free plan allows three decks a month; Pro costs $24 a month. The iOS and Android apps are marked as coming soon.

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.
