See It in Action
Real-world examples of semantic search finding exactly what you need.
Resume Search
You've applied to hundreds of jobs and you're sick of digging through 100+ resume files. Now you're applying to TikTok—just search in CosmaSense, drag the right resume, and you're done. (Pure semantic vector search with natural language—no complicated filters.)
Image Search
You're a photographer and you want to upload to Unsplash right now. Instead of hunting folders, just search what's in the image ("golden hour street portrait", "snowy mountain drone shot") and pick the match. (Shows multi-format + media support.)
Email Attachment Search
Someone sent you a contract last month but you can't remember when or who. Just describe what you're looking for and CosmaSense finds the attachment instantly. (Works across all your downloaded email attachments.)
…and a lot more!
