User stories explained simply: how to divide a product into steps

You may have been told your project will be divided into 'user stories'. The term belongs to developers and hides an idea you already practise when commissioning work: describe a step by what can be verified at the end.

How to write an application brief: the perfect brief does not exist, start messy

A brief's blank page blocks more projects than the budget. A disorganised twenty-minute draft is enough to start, provided someone then asks the questions you missed and returns a clean document for your signature.

The August 2026 GitHub outage: 2.9 billion code contributions per month

GitHub was unavailable almost eight hours on August 17, 2026 and three days later published the figure explaining it: monthly code submissions had doubled since April. What that wave changes for anyone having software built.

Cursor vs Windsurf: the latter is now Devin Desktop, and the question has changed

Searching 'Cursor vs Windsurf' in 2026 leads to an outdated comparison: Windsurf changed names through an automatic update in June 2026, and its old pricing page redirects. What remains to compare, and what neither does for you.

Exposed API keys in an AI-built application: what an auditor sees

An application delivered in three days welcomes its first users and everything seems to work. An auditor opens it and checks the same three places. What they find, why the demo hides it, and what a business owner can require without reading code.

Emergent review 2026: the autonomous agent targeting France, and the autonomy argument

Emergent builds an entire application while you watch, claims half a million applications created in France, and sells autonomy as its advantage. What it does better than us, and the three missing pages.

Building an application with ChatGPT: what you get and what is missing

Building an application with ChatGPT works up to an identifiable point. What the conversation provides, what OpenAI's coding agent adds, what it costs, and the three things it will not do for you.

Our Manus review in 2026: the autonomous agent that does everything except let you decide

A Manus review depends on what you ask it to do. For producing market research or a report overnight, the autonomous agent is the market's most versatile. For building software you will maintain for three years, the question changes.

Project scoping: an AI that asks questions is better than one that guesses

A founder sums up the problem in one sentence: without a real specification, the tool designs things its own way and they spend their time catching up. Scoping through questions solves this before the first line of code, provided someone asks them.

Build a mobile application with AI without coding: what remains before publishing

Three tools now build mobile applications from written instructions, and one submits to the App Store in two clicks. What they charge, what you take when leaving, and the part of the work none of them writes.

Maintaining an AI-built application: understanding what you had built

Vibe coding works until someone has to take over the application. Two accounts, one from a founder and one from a French developer, describe the same wall. What brings it down is a document you have read and approved.

What building an application with AI really costs: $2,000, zero users

An interface designer reports spending $2,000 on vibe coding tools for almost no users, with small features costing over $10 apiece. The expense comes from everything that had to be rewritten after the first code was produced.

v0 or Lovable: one builds a screen, the other an application, neither writes the specification

v0 excels at interfaces and fits into teams that already have review rules. Lovable puts a complete application online in an evening. Neither produces the document stating what the product must do, and that absence has a later cost.

A free AI assistant delivering code that did not compile: three tuning passes

Why agency prices have not followed the fall in AI costs

What cost $60 per million tokens in late 2021 now costs between $0.06 and $0.40 at equivalent performance, a reduction of 150 to 1,000 times. Meanwhile, a developer's average daily rate in France remains around €629. Someone is keeping that margin.

AI makes experts slower: why approval must be an architecture, not a chore

The METR study measured experienced developers as 19% slower with AI, while they believed they were 20% faster. Review and verification consumed the gain. The problem is not review: it is where we put it.
