Open-source AI tool to generate grounded speaker notes from PPTX with vision review.
Visit WebsiteFeature-by-feature
Speaker and Chili Piper serve completely different functions. Speaker is an open-source command-line tool (Codex skill) that extracts content from .pptx files—titles, body text, placeholders, tables, charts (incl. axes, series, legends), and even OCR for images/screenshots. It renders slides to PNG for visual review and generates grounded speaker notes per slide, writing them directly into the PowerPoint notes pane or exporting as DOCX. Critically, it supports fallback OOXML extraction for SmartArt and grouped shapes, and includes a vision review packet for verification. Its strengths are accuracy for visually-rich decks and deep PPTX parsing. By contrast, Chili Piper is a SaaS platform for B2B revenue teams. Its features focus on identifying website visitors (via AI and CRM data), scoring intent, and instantly converting them to meetings. Key features include Form Concierge (turns form submissions into booked meetings), Concierge Live (instant phone calls), Chat AI (24/7 qualification + routing), Distro (auto-routing leads in Salesforce), Re-Engagement (recovers no-shows), Email Composer, Spam Checker, and Meeting Prep. Routing rules are set via plain English (Chili Assist). It integrates with Salesforce, HubSpot, Slack, calendars, and Clearbit. The two tools share no overlapping features; they address different domains.
Pricing compared
Speaker is completely free and open-source, available as a Codex skill on GitHub. There are no paid tiers, no subscription—it costs nothing but requires technical comfort with command-line and Claude Code skills. Chili Piper does not disclose pricing on its website; it uses a contact-for-pricing model typical of enterprise SaaS. Based on its feature set (AI routing, Salesforce integration, chat, etc.), it likely requires a significant annual subscription. Chili Piper explicitly notes it is not for teams wanting a free plan—it is paid and enterprise-focused. There is no free tier or trial mentioned. Given the disparate pricing models, the decision is clear: if your need is presentation notes, Speaker offers exceptional value at $0. If you need sales conversion automation, expect to pay for Chili Piper's enterprise-grade capabilities.
