Small tools that get you unstuck
Each one solves a single concrete problem. All are free; all but two work without an account — Diary and VidQuiz need one. Open it and use it.
Web services
CheckCV
You send your CV to dozens of openings and hear nothing back. Upload the file and a minute later get seven scores and a list of edits — what is wrong with the layout, which words are missing, and whether it survives the screening robots.
checkcv.xyz
KidSpace
You moved to Bali with a child and have no idea where to take them. 426 places — schools, classes, playgrounds, shops — with the district, monthly price, language of instruction and the owner’s WhatsApp.
kidspace.id
Luxembourg homes
The portal shows fifteen listings and will not page further, so the rest of the market has to be prised out one filter at a time. This sweeps every price band onto one page: filter by price, bedrooms, region and type. Listings across the border in Saarland and Lorraine are marked as such.
immo.alftech.space
VidQuiz
Thirty identical half-hour intro calls is fifteen hours, and half those people are ruled out in the first minute. Ask your questions once, let candidates answer on video by link, and watch on fast-forward.
vi.alftech.space · Account required
Invoice & act
A Russian bank will not clear a payment from abroad on an invoice alone — currency control wants the full set. Fill one form and get the contract, invoice and act at once, bilingual, with the right VAT wording.
schet.alftech.space
Letter decoder
A letter arrives from the tax office or the commune in a language you do not read, and you cannot tell a fine from an advert. Paste the text and find out what is wanted, by when, and what happens if you are late — with a draft reply.
razbor.alftech.space
Invoice generator
You still make invoices by hand in Word and retype the same details every time. Fill the form and download a finished PDF invoice, act or delivery note, in Russian or English.
invoice.alftech.space
Shrink
Your photo weighs twelve megabytes and the form accepts five. Drop in a batch of images or video and get a zip of the right size. Nothing is uploaded anywhere — it is all recompressed in the browser, and GPS tags disappear along the way.
shrink.alftech.space
Vivre ensemble
You are taking the Luxembourg citizenship test and do not know what to expect. 367 questions with every answer explained, and a mock exam in the real format — 40 questions in an hour, 28 correct to pass.
vivre.alftech.space
LuxFlash
Luxembourgish is required for the Sproochentest and textbooks barely exist. 2400 words as cards: what you know comes back less often, what you forget comes back sooner.
luxflash.alftech.space
Luxembourg net pay
You were quoted a gross figure and have no idea what lands in your account. Works it out by tax class and contributions, including the deductions nobody mentions. A detailed mode covers the awkward cases.
luxtax.alftech.space
BULU
You are on Bali and want a game of badminton or padel, but search only turns up hotels. Eleven halls and clubs with addresses, opening hours and a booking link.
bulu.alftech.space
QR
You need to hand people a link, a Wi-Fi password or a business card, and all you have is a phone and a printer. Draws the code right on the page — links, passwords, contacts, in batches if needed; download as image or vector. Nothing is sent anywhere.
qr.alftech.space
Traces
You send a photo or a document to strangers, and along with it go the coordinates of your flat, your camera’s serial number and the author name inside the contract. Shows exactly what the file says about you, and strips it. All in the browser, nothing is uploaded.
traces.alftech.space
JSON Tools
An API answered with one line three screens long and something in it is broken. Formats it, points at the exact line and column of the error, minifies it back and converts it to CSV. All in the browser.
json.alftech.space
Palette
You need colours for a page and your eye has gone numb. Builds combinations — complementary, analogous, triadic — with a lock on the one you like, and hands them over as ready CSS and Tailwind variables.
palette.alftech.space
README Maker
You published a project with no description and cannot face writing one. Fill the form and get a finished README with badges, install and usage sections, straight to the clipboard.
readme.alftech.space
Prismatic
You need to look inside Elasticsearch and installing Kibana for five queries is too much. Shows the cluster, nodes, indices and shards, with a query console. You enter the cluster address; nothing is stored.
prismatic.alftech.space
Diary
You want to write for yourself, but not into notes your cloud reads. Markdown entries, mood, tags, highlighted search, a calendar. Its own sign-in, and entries are encrypted with a key that lives only on this server.
diary.alftech.space · Account required
Cut
You filmed something long and need ten seconds from the middle — or a looping GIF that plays by itself. Cuts and builds it right in the browser; the file never leaves your machine.
cut.alftech.space
PDF
Merge PDFs, pull out pages, rotate, reorder, turn photos into a PDF and shrink a scan — all inside your browser. No upload, no account, works offline.
pdf.alftech.space
Convert
iPhone HEIC into JPG or PNG, JPG, PNG and WebP into each other, shrink to a size, metadata stripped — all inside your browser. No upload, no account, works offline.
convert.alftech.space
Markdown
Write Markdown and see the page as you type: tables, checklists, code. Save .md or a standalone .html, copy HTML, print to PDF — all inside your browser. No upload, no account, works offline.
md.alftech.space
Regex Tester
You wrote a regular expression and it does not match what it should. Highlights matches as you type and explains the pattern piece by piece. Whatever it could not parse it labels as unparsed, instead of pretending it understood.
regex.alftech.space
Circadian rhythms
When to sleep, when to catch daylight, when to skip coffee — calculated from the time of day and your schedule. Nothing is measured: it is a model, and it says so.
circadian.alftech.space
Serenity
A mood and connection journal: a daily check-in, a log of real contact with people, gentle suggestions. Help goes through an international directory of crisis lines with a country picker.
serenity.alftech.space
Games
Leveling
Level up a character with real actions: pick a class, get daily tasks, grow six stats. Experience comes from what you actually did — no button gives it to you. A missed day takes nothing away, and coming back after a break earns an achievement of its own.
solo.alftech.space
Solo Leceling
A browser RPG: gates from rank E to S, ten skills, a shadow army from level ten. Everything stays in your browser, no sign-up.
gates.alftech.space
NeuroForge
Twelve exercises for attention and memory — N-back, Schulte tables, the Stroop test. Difficulty adapts to you, and what you forget comes back at the right interval.
neuro.alftech.space
The Pharos
A twelve-level platformer. Arrows and space, pause on “P” — it opens and plays right away.
arcade.alftech.space
Telegram bots
BookKicker
The book has sat in your e-reader for six months while Telegram stays open all day. It sends your book in pieces, once an hour from eight to eight. Your own file, or one from the free library.
@BookKicker_bot
DisasterMesh
An offline notebook for the bad day: emergency contacts, reunion points, a 72-hour checklist and messages to send when the network comes back. Everything stays on this device; nothing is transmitted.
mesh.alftech.space
CheckCV Bot
CheckCV without leaving the chat: send your CV as a file, get the scored breakdown and the edits back.
@checkcvbot
10 Daily Goals
Asks about ten goals in the morning and comes back in the evening for the tally.
@productiveme_bot
Klotho
A small chat helper.
@klotho_bot
Fats Fighter
Logging meals by hand gets abandoned around day three. Photograph the plate and the calories and macros come back; you can also dictate it or simply type it. Daily, weekly and monthly summaries, and one missed day does not burn the streak.
