Baksell — Demo video

Backsell Podcast ads today are broken. They are loud, awkward, and obviously shoved in at random moments , so listeners skip them every time. Advertisers waste money, and creators lose trust with their audience. Backsell fixes this. Podcast creators upload their episodes, browse a marketplace of available ads, and pick the ones that fit their content. Backsell's AI then does the rest: it listens to the entire episode, finds the perfect natural moment to mention the product, writes an ad script that fits the conversation, and delivers it in the host's own voice ,so it sounds like the host genuinely brought it up, not like a commercial was spliced in. For creators: Upload your podcast, choose an ad, get paid , no extra recording, no editing, no awkward ad reads.
