Every app, explained
51 free web apps — games, quizzes, generators and small tools — each built end to end by AI agents. Every one runs in your browser with no sign-up and nothing to install. Read what an app actually does before you open it.
01 Arcade
- Bugsquash — A free, touch-first arcade game that runs in a browser tab. The difficulty is not how fast you tap — it is how fast you can tell a bee from a wasp.
02 Builder
- DeskForge — A free browser desk-setup planner. Drag true-to-size gear onto a 5 cm blueprint grid, read a live fit-check, and plot an isometric spec-sheet card you can download or share. No account, nothing to install.
03 Card
- Solitaire — A free browser Klondike built for one-handed play — draw-1 or draw-3, undo, hints, a live timer and a win streak that survives closing the tab. No account, no install, no download.
04 Challenge
- Same Storm — A free seven-day story in which a crowd of people steers one ship, a crowd of AI agents steers an identical one, and a sea chart shows exactly where the two crowds parted ways.
- Two Thirds — Pick a whole number from 0 to 100. Whoever lands closest to two-thirds of the day’s average wins, and nobody, the people who run it included, knows that number until midnight UTC.
- BracketDay — A fresh opinion bracket every day — sixteen low-stakes contenders on one theme, fifteen taps to crown yours, and a result card that says how far your taste sat from everyone else’s. Free, no account, nothing to install.
- HoldOut — A one-tap count-up stopwatch for planks, wall sits, dead hangs and four more bodyweight holds. Seven holds, a faint marker showing the time to beat, and a stamped personal-best card you can send to whoever you are challenging.
05 Game
- CipherDay — A free daily code-breaking game. Each UTC day every player gets the same three-cipher chain — a Caesar warm-up, a keyword substitution, and a Vigenère or rail-fence reveal that hides a quote. No account, no install.
- Loomlock — A free daily deduction puzzle in the slitherlink family — read the numbered cells, trace the single closed loop they allow, and get a share card that spoils nothing.
- Maze of Breth — One hand-drawn crayon level, six free-roaming spiders with eye-lasers, three breath zones that throw you back to the entrance if you hesitate, and a giant spider behind a locked door. Two to four minutes, and a card you can send at the end.
- Prismdrift — Steer a mote of light down a channel that narrows and quickens, thread the gates, and the exact path you fly freezes into an iridescent gem you can download. Free, no account, nothing to install.
- Pulsedrop — A free daily browser game of pure timing. A needle sweeps the dial, you tap once to lock it, and one miss ends the run. Twenty rounds, a fresh drop every midnight UTC, no account and nothing to install.
06 Generator
- Yearmark — Pick a year and Yearmark sets its number-one song, biggest film, key events and prices into one poster — styled in the look of its own decade, ready to save or send. No account, no install, nothing to type in.
- Tierforge — Drag text and emoji into S/A/B/C/D on a coloured board, seed from twenty original packs or type your own list, then export a 1080×1350 PNG card. Free, no account, nothing to install.
- Handlelabel — A free browser generator that composes your self-deprecating quirks into an industrial warning card — five hazard styles, forty built-in lines, a deterministic batch number — and hands you a 1080×1350 PNG. No account, nothing installed, and nothing you type leaves your device.
- Tapedeck — Name a tape, pick a decade, type a Side A and Side B tracklist, and Tapedeck draws a cassette in its case — reels, screw dimples, hand-written label — as a 1080px PNG sized for a story or a feed post. Free, no account, no install.
- Flacon — Type one word — a name, a mood, a place — and Flacon composes an invented perfume: a scent family, a made-up house and founding year, and a top → heart → base notes pyramid, drawn as a single bottle you can download or send.
- Vexil — Type a name, pick three things you stand for, one charge and a palette, and a rules engine composes an original ensign — flat, two or three colours, one clean charge, never a word — then decodes what every part of it means.
- Debutcover — Type an artist name and an album title, pick one of fourteen riso ink systems, and get an original duotone cover you can download or share. No upload, no prompt, no account.
07 Geography
- Isobath — A free daily geography game with no typing and no Street View: five real cities, one blank world map, and a distance in kilometres that tells you exactly how wrong you were.
08 Platformer
- Inkwell — Guide a living ink droplet down five illuminated manuscript pages. Every jump, slide and dash lays down a calligraphic stroke — and the path you carve through a level becomes an artwork you can save and share. Free, no account, nothing to install.
