Cash Book is an expense tracker for iPhone built on one idea: logging so fast you actually keep doing it. Say "12 euros lunch" and AI turns your voice into a transaction with amount, merchant, tag and date. Snap a receipt or a screenshot and every line is read for you. Set up one Apple Shortcuts automation and every Apple Pay tap logs itself. Or use the keypad: three taps. Your money is then organised the way you think: tags grouped into categories, accounts for cash, cards and savings with one net-worth number, and monthly or weekly budgets that show what is left. Insights show where the money went, what changed against last month, and six months of income against expenses. There is no account and no sign-up, and Cash Book never connects to your bank. Data stays on your iPhone, with optional encrypted iCloud sync to your own Apple account. 128 currencies, 26 languages, Face ID lock, CSV and Excel export.

AI Image Expander is a free online outpaint tool built for the moment a photo is almost right—but the platform wants a different frame. Creators shoot square or landscape, then need 9:16 Stories and Reels, 1:1 feed posts, 16:9 covers, or other catalog ratios. Stretching pixels looks cheap; hard crops cut faces and products. AI Image Expander grows a new canvas around the original and fills empty borders with AI-generated context so the subject stays intact.How it works: users upload a single JPG, PNG, or WEBP photo, pick an aspect ratio (1:1, 2:3, 3:2, 16:9, 9:16, 3:4, or 4:3), and choose scale—Auto or fixed multipliers such as 1.2×, 1.5×, or 2×. A live preview shows the final canvas size before spending a free expand. The pipeline keeps the original image centered and outpaints only the borders required by the target layout. When done, users download a watermark-free result. Signing in with Google unlocks expand history for later re-downloads and a higher free daily quota.Supported inputs typically allow up to 10 MB per file, with shortest side at least 256px and longest side at most 4096px. A 25MP canvas safety limit blocks scale choices that would produce an oversized result. Guests receive a limited number of free expands per day; signed-in users get more. Abuse controls such as captcha, rate limits, and file validation help keep the free tier available. Uploads are processed to fulfill expand requests and are not used to train public AI models; retention details live on the Privacy Policy page.Pricing for the core experience is free. Daily quotas protect capacity; future paid features may appear later, but ordinary free expands do not require checkout today. The product runs in modern browsers on desktop and mobile—no installer and no offline generation mode. An internet connection is required for each job.Responsible use is part of the product story. Outpainting may leave soft seams, blur, or invented background detail—especially near people, text, or logos at the edge. Results are creative assistance, not a guarantee of perfect photoreal borders. AI Image Expander is therefore positioned as a practical social and commerce helper for creators, shop owners, travel posters, and listing editors—best paired with a quick visual review before publishing.In short, AI Image Expander packages generative outpainting into a reliable free web tool: social aspect presets, Auto or fixed scale, canvas preview, free daily quotas, optional history after sign-in, and watermark-free downloads for anyone who needs Story and Reel frames without reshooting.

KidTeller is an AI storybook studio for parents, grandparents, and teachers who want a child to see themselves inside a real story. You start by describing the hero: a name, an age, a few favorite things, and a photo. KidTeller turns that photo into an illustrated character and writes an original story around it - not a template with a name inserted, but a fresh narrative built on a proven story structure and tuned to the child's age group, from simple repetition for toddlers to want-versus-need arcs for readers 8 and up. Pick a theme, an illustration style, and one of 30+ languages, and the first draft arrives in minutes. Nothing is locked. You can edit any line of text, swap or regenerate pictures, add more characters - siblings, grandparents, the family dog - and re-run the cover until it feels right. When the book is ready, read it in the browser or in the KidTeller app for iOS and Android. In the app you can also clone your own voice from a one-minute recording.

I've been building LifeOdds (a Monte Carlo decision engine for big life choices) and kept coming back to "should I quit my job" as the single most universal, highest-stakes version of that problem. So I looked at a dozen existing calculators for it to see how they handled the two genuinely uncertain variables — how long a job search actually takes, and what you actually land. Every one treats both as fixed inputs. Pick a number, get an answer, done. That's not a simplification, it's most of the real risk in the decision, hidden. So I built [Should I Quit My Job](https://shouldiquitmyjob.app) to run it properly: 1,000 Monte Carlo simulations over a 5-year horizon instead of one guess. Four inputs — current salary, target salary, expected search length, savings runway — and it varies the uncertain ones across realistic ranges (searches consistently run longer than people expect), compounds raises on both paths, and reports the break-even month, your odds of being ahead at year 1/3/5, and the case every single-point calculator misses entirely: your search outlasting your savings before you land anything. One thing I'm genuinely undecided on: an optional fifth input for how the new role would actually feel day to day, converted to a rough yearly value using real compensating-wage-differential research (not a random slider). Feature or scope creep? Curious what this community thinks.
