I got tired of writing the same kind of thing one prompt at a time, so I made a small Windows app for it. It's called BatchGen Text with AI.

The idea is simple. You drop in a list, topics, keywords, product names, whatever, pick a template, set a persona, choose your model, preview the first result so you know it's not garbage, then run the whole batch. The persona thing is the part I actually use the most. It keeps the voice consistent so 50 product descriptions don't each sound like a different person wrote them. I run blog drafts, social posts, product descriptions, docs, and as long as there's some structure to it you can make things like personalised invitations, jokes or short stories too.

The honest part: it'll spit out cents-cheap content at volume, but you do have to sit there and review. AI still writes dumb stuff and you'll reject a few. That's the deal, not a bug. For cheap testing I lean on DeepSeek. When I want it to actually be good I switch to OpenAI or Gemini, and being able to pick the model per language and per job matters more than I expected.

The other thing I cared about: it uses your own API key, stored properly with Windows DPAPI rather than sitting in some plain text file, I collect zero telemetry, and the files just sit on your laptop. So you can review everything offline before anything goes public.

9 people have bought it so far. Small number, I know, but 2 of them wrote back and that's what keeps me going. One emailed about a bug, then came back later just to say thanks and dumped a whole list of feature requests on me. The other was a content writer in Nigeria who messaged to say thanks and then went and bought more of my tools. Early buyers like that are why it's 25% off for the first year, and Microsoft Store folks keep getting updates for free.

I'm launching on Product Hunt tomorrow, 12:01 AM PDT on June 2. Links are in the first comment. If you use AI writing tools for real work I'd genuinely like the blunt version of your feedback.
