What makes SynthIt different: Connections
Every source you add, linked together
Generic AI tools treat every upload as an island. SynthIt links the people, ideas, and claims across everything you've added — so you can ask what your sources agree and disagree about.
Start with one file.
Upload a PDF, paste a link, or drop in a video — SynthIt takes it from there.
