Vladimir Gromozdin🙏 3 karmaFeb 18, 2026@TendemI work on the Tendem team, so take this with that context — but I also use the product constantly for my own work. I've used Tendem to research AI directories — finding relevant ones, pulling submission requirements, organizing everything into a spreadsheet I could act on. I've also used it for copy edits — sending over drafts and getting back tightened, polished versions without going back and forth with a prompt ten times. The thing that keeps me coming back is how little I have to think about the handoff. I describe what I need, send it, and move on to something else. It's slower than getting a ChatGPT response, sure. But I get something finished — not a starting point I still need to rework. When you use AI tools for this kind of work, you trade waiting time for cleanup time. Tendem flips that. I'd rather wait and get a result I can use than get a fast draft I have to fix myself.
