The default mode condensed a video into key points broken into chapters, each with a clickable timestamp. The point was speed: a two-hour video became a short read you could scan in a minute, and one click dropped you back into the video at the exact moment. For anyone who used YouTube as a reference library, that combination of digest plus jump-to-moment was the core of the product.

Pro Summary traded brevity for structure. According to Tammy AI, this mode produced a longer, more balanced breakdown of the video's arguments, still anchored to timestamps. It suited people who needed to understand the shape of a talk rather than just its headline points, which is why it was pitched as the paid-tier feature on the higher plans.

The chat panel let you ask questions about the video and got answers pulled from its content, each linked to the relevant moment on the timeline. Rather than scanning the whole summary for one fact, you could ask directly and then verify it by clicking the timestamp. That grounding in the source video was what separated it from a generic chatbot.

Tammy AI ran a discovery section that rounded up summaries of popular channels and trending videos, so you could browse summaries without pasting a link yourself. It turned the tool from a one-off utility into something closer to a reading feed for people who followed the same channels regularly.

Saved summaries went into My Library, where you could organize them into folders and come back to them later. The free plan capped the number of folders, and the premium plan lifted that limit. For students and researchers, this was the feature that made the tool sticky, because it accumulated into a personal knowledge base over time.

The paid plans added full multilingual support, so summaries could be produced in more than just English. That mattered for viewers who followed channels in other languages or wanted to read a summary in their native tongue, and it was one of the clearest lines between what free and paid users could do.
