Spotlight: Vaultmate — a decision engine that beat a library comparison tool
Something interesting happened between when this product was named and when it launched. Our records call it Vaultmate, pitched as a way to compare Steam libraries and find a co-op match. But the live site at getvaultmate.com is running a different product entirely, called PlayNext, with a different job to do. Worth calling out plainly, because it is the most honest thing we can say about where this founder is right now: still finding the shape of the thing.
What's actually live is a single-player recommendation feed. You connect your Steam account, it reads your owned games, playtime, recent sessions, and backlog, and it builds a taste profile from what you finish, replay, drop quickly, and avoid. Then it hands you a short list for tonight instead of a wall of tiles. The pitch is right there in the copy: Steam is great when you want to shop, PlayNext is for when you want an answer.
The smart part is the framing, not the tech. Anyone can build a recommendation list. What PlayNext is selling is the feeling of opening a streaming app and getting a decision instead of a menu. That's a real gap. Steam's own recommendations are shopping prompts, built to sell you something new. PlayNext is explicitly built to point back at your backlog and your library, including games you already paid for and quit too early. The example rows in the copy back this up: "because you replay strong combat loops" grouping Hades, Risk of Rain 2, and Deep Rock Galactic together, or "low commitment tonight" pulling in Balatro and Stardew Valley. Those aren't generic genre tags, they read like actual session-behavior clusters, which is the only reason a tool like this is worth trusting over just scrolling your own library.
Who should try this: anyone with a Steam library big enough to have forgotten what's in it. If you've got 200+ owned games and you spend more time deciding than playing, or you keep buying new releases while ignoring a backlog full of things you already liked, this is aimed squarely at you. It's also a reasonable fit for someone who likes short, low-friction sessions and wants the app to do the filtering rather than doing it themselves every night.
Who should skip it: if you're a completionist who already knows exactly what you're playing next, there's no problem here to solve. Same if you don't play on Steam, or if your library is small enough to scan in ten seconds. And if the co-op matching angle from the original name and tagline is what drew you in, be aware that's not what's live today. There's no library-comparison or friend-matching feature visible on the site right now, just single-player taste detection.
Where this goes next, and this is our read, not confirmed: the founder has clearly pivoted from a social/comparison angle toward a personal-recommendation angle, and the personal angle is the stronger wedge. Comparing libraries with friends is a nice-to-have; deciding what to play tonight is a nightly habit, which is a better hook for retention. If PlayNext can nail the "detect your habits" step accurately across genres beyond the five games shown on the site, and if the recommendations hold up once you've played through the obvious picks, there's a real case for this becoming a daily-open habit the way a streaming home screen is. The naming and positioning still need to catch up to what's actually built, but the product decision underneath it looks like the right one.
