From their web site circa 2004 via archive.org ---- Tonic's unique and patent pending PowerPoint® library provides an enterprise-ready API for you to programatically work with PowerPoint® documents, taking slide presentations to the next level of sophistication.
The library provides a 100% Java API to read, create and manipulate PowerPoint® presentations. Use the library to generate new slides, populate presentation templates or extract data from existing presentations. The library supports the standard PowerPoint file format that is used by PowerPoint 97, 98, 2000, XP, etc.
The library works directly with PowerPoint® files. This means you don't need the PowerPoint® application to use the library, only to view generated presentations.
Turn Slide Presentations into Powerful Business Tools Here are just some of the ways to use Tonic's PowerPoint® library:
Convert PowerPoint® presentation into other formats e.g. PDF, HTML Extract data from PowerPoint® templates Auto-generate entire presentations from existing data sources e.g. a database or spreadsheet Manage collections of presentations Extract slides or data from existing presentations to create new ones For examples of what Tonic Systems' PowerPoint® library can do for your business, see our Case Studies.
Availability and Pricing The library is currently shipping. A license to use the library is priced at US $5000, where the envisaged usage is a single instance running inside a web application, serving unlimited users. For other usage models or inclusion in a product, we are happy to discuss different pricing options. Site and global licenses are also available.
Slide.com doesn't do anything with PowerPoint. If you go yo Slide.com, you can see that they are not a presentation software company; they are a social networking widget company. Slide.com is not about technology--in fact, their tech looks downright trivial. They are all about branding. Slide.com has no technology to buy; they only (maybe will sometime) have customers to buy.
Zenter is an web based presentation app that promises to really take advantage of being online. Users will have the regular functionality of PowerPoint, but with the ability to directly add content from the web (Google Images). Each public slide show will also be put into a public library, for other users to remix or just drop into their show.
Slide has more to do with photos, I agree.
