Free version does not output file as PPT filetype. Limited to only 5 slides in the output file in the free version. Not clear if it takes markdown (.md) file format as input - I suspect it does not. Limited (pre-built) color / thematic options, unless you are willing to create and upload your own color palette, themes, and templates.

Horribly slow, and horribly confused. I chose OKKslides because I *had* to construct a presentation in .PPT format, and this was pretty much the only AI tool that would output a PPT file. I gave OKKslides a markdown file of my presentation - the pitch deck for a startup - with all 10 slides precisely outlined, the themes clearly defined, and markdown annotations for the font size and type completed. And then I uploaded the supporting documents and references that OKKslides asked for in order to "make the presentation more detailed." Pretty sophisticated, I thought, thinking all that extra work would pay off perhaps, but at least suffice. But OKKslides STILL took it **upon itself** to go scrape the internet and find information about a different company - misspelling the startup's name in the process - and retrieving information relevant to a *completey different industry*, overwrite some of the content, and then incorporate these "improvements" into my presentation. It made the simple job WAY more complicated than it needed to be, and then charged me tokens for this "feature". Oh - and the text / slide editor? Completely counter-intuitive and with limited functionality. I wouldn't be surprised if they charged me tokens for trying to correct spelling and spacing mistakes as well. (For instance, put a space in between the title words, wouldya?) Could it be any more frustrating? My advice: Avoid PowerPoint. And avoid OKKslides, unless you ABSOLUTELY need to use PowerPoint. Even then use it for design ideas, perhaps. I hesitate to recommend this AI tool to anyone.
