Brethof AI is a small privacy-first studio in Poland. A handful of humans, shipping in public, and telling you when a tool isn't worth your time. Two things are for sale. Everything else — the reviews, the lists, the newsletter — is free, and stays free.
That is the whole scope, and it's worth stating plainly, because most of what you'll read about AI tools comes from someone who has never run them. Brethof runs them, and shows the failures.
What we make, what we don't, and how the operation funds itself.
What we make: **brethof-brain** — memory your AI agents carry between sessions. It is a cloud service, and the page says so, with the security details one click away. **Brethof Voice Pro** — speak, and it types, in your language or someone else's, on your own machine. You buy it once and it stays yours; no subscription appears later. **Nova** — the channel where the studio uses the tools in public and says what failed. And the free lists, curated, every claim carrying a receipt so you can check it yourself.
No paywall, no Patreon, no courses. Everything except the two products is free, and free doesn't quietly turn into paid. No pretending. If a tool is bad, the page says so. One of the lists exists precisely to name the practices that waste your afternoon. And no trade. Three things are not for sale: your data stays where you put it, Voice Pro is bought once and stays yours, and the bad reviews get published too. Those three are the whole company.
How it works. The promise across everything is the same: the tools get better the more you use them, and keep your work yours. Your voice, your language, your sessions — they stay where you put them. And when the studio is wrong, the correction comes in public, the same place the claim did. That's the whole model, and it's why the studio is small and intends to stay that way.
The newsletter covers new releases, real benchmarks and the occasional deep dive — no spam, one-click unsubscribe. The lists are free and carry receipts. Nova is free. The honesty is free. The two products exist to keep that going. Brethof Voice Pro — spoken once, bought once, yours forever. Or brethof-brain, carrying your agents' memory between sessions. Either way, you're paying for the same small thing the free pages give you: a studio that would rather publish the bad review than lose the good one.
