AI Tools for App Development on macOS

Our macOS apps support developers with the everyday tasks that often consume a lot of time but add little value. They help you organize content cleanly, document it in a reusable way, and keep it consistent across projects, instead of dealing with folder chaos, copy and paste workflows, and manual tracking lists.
A key focus is text-related work in software projects, including localization, App Store content, technical documentation, and structured post-analysis of crash reports. The goal is to make information easier to access, simplify comparisons, and capture results in a way that remains understandable and reusable later.
AI can optionally support these workflows, for example for drafting, translating, or summarizing content. It is not required. If you prefer to work without AI, everything can be handled manually or through templates that you run in external tools. If you choose to integrate AI, you can speed up your workflow while staying fully in control of what is sent.
Openness matters to us. Instead of being tied to a single provider, you can choose between different services depending on your needs, including OpenAI, Google Gemini, Anthropic Claude, Perplexity AI, and DeepL, and compare results. At the same time, all data remains local on your Mac, with no cloud dependency and no automatic data transfer.

BetterLocale Crash

AI-supported localization for Xcode projects

First release: January 2026

Mac-256@2x
BetterLocale Crash hilft dir, iOS- und macOS-Crashlogs schnell zu verstehen und sauber zu dokumentieren. Während klassische Monitoring-Tools zuverlässig melden, dass ein Fehler passiert ist, setzt BetterLocale Crash beim Warum an. Die App importiert Crash- und Logdateien, reduziert umfangreiche Reports automatisch auf die relevanten Stellen und macht sie dadurch besser vergleichbar.
Beim Laden werden aussagekräftige Stackframes herausgefiltert, Ursachen lassen sich gezielter eingrenzen, und Duplikate werden versions- und thread-unabhängig erkannt. So bleibt auch ein großer Crash-Bestand übersichtlich, und du arbeitest nicht ständig dieselben Varianten durch.
Für die Analyse hast du drei Wege, je nach Setup und Arbeitsstil. Du kannst alles komplett manuell machen und deine Bewertung, Ursache und Notizen direkt im Editor festhalten. Wenn du KI nutzen willst, aber keinen eigenen Account oder API-Key hast, erstellt BetterLocale Crash strukturierte Vorlagen, die du in einem externen KI-Client wie ChatGPT ausführen kannst. Das Ergebnis übernimmst du anschließend per Zwischenablage zurück in die App. Und wenn du bereits einen Account bei einem Anbieter hast, kannst du Analysen direkt in der App erzeugen lassen. Das ist optional, spart aber spürbar Zeit, weil der Schritt über externe Tools entfällt und Ergebnisse direkt gespeichert werden.
Optionaler Source-Code kann als Kontext ergänzt werden. Crashes lassen sich filtern, gruppieren und über Statuswerte verwalten. Alle Daten bleiben lokal auf deinem Mac. Unterstützt werden unter anderem OpenAI, Google Gemini, Anthropic Claude, Perplexity AI und xAI Grok. BetterLocale Crash ist bewusst kein Monitoring-Tool wie Sentry, sondern ein Werkzeug für strukturierte Nachanalyse, Vergleich und Dokumentation von Crashlogs.

BetterLocale Code

AI-supported localization for Xcode projects

First release: January 2026

BetterLocaleCodeIcon256x256
BetterLocale Code is a macOS tool that makes Xcode localization finally feel the way developers expect it to. Instead of getting lost in .lproj folders, .strings files, and multiple .xcstrings versions, you manage everything in one central editor built around your Xcode project. You instantly see which keys are missing, where translations are incomplete, and which languages are out of sync. No searching, no guesswork, no endless copy and paste.
The real strength lies in the translation workflow. You can bring your app into virtually any language without setting up an expensive or slow process. If you want, you can use AI directly inside the app with your own provider accounts, such as OpenAI, DeepL, Gemini, Claude, or Perplexity. You decide how much context to provide, what level of quality you expect, and how you manage costs. If you prefer not to use direct API integration, BetterLocale Code generates structured templates and instructions that you can run in external tools like ChatGPT. You then copy the results back and continue managing everything in one place.
Because BetterLocale Code works directly with your project, it fits naturally into your Xcode workflow. You are not translating “somewhere else,” but directly at the strings that will actually be part of your build. Conversions between XCStrings and .strings are done with a single click, and you can iterate quickly because updated texts are immediately available in your project. In the end, it is an ideal complement to Xcode. Xcode supports localization, but BetterLocale Code makes it faster, clearer, and more cost-efficient, especially when working with many languages and frequent updates.

BetterLocale Store

AI-supported localization for App Store Connect metadata

First release: January 2026

BetterLocaleAppsIcon256x256
BetterLocale Store makes App Store localization on macOS finally stress-free. You manage all your App Store Connect texts in one place instead of jumping through countless tabs, copy-paste snippets, or outdated Excel files. You instantly see which languages are incomplete, where text exceeds limits, and whether your content stays consistent across all localizations. This keeps your App Store presence aligned, even if you frequently refine texts or add new languages.
Translation is flexible and adapts to your workflow. If you prefer not to use your own AI account, the app can generate structured templates and translation prompts for external tools like ChatGPT. You run the translation there and paste the result back into BetterLocale Store. If you already use AI services, you can trigger translations directly inside the app via API, for example with OpenAI, DeepL, Gemini, Claude, or Perplexity. Your data remains local on your Mac, and any usage costs are handled only through your own provider accounts.
In short, BetterLocale Store takes care of the tedious part: keeping content organized, identifying gaps, maintaining clean metadata, and integrating translations into a controlled workflow. It is ideal for indie developers and teams who want to manage App Store metadata quickly, consistently, and affordably across multiple languages.

BetterLocale Doc

AI-supported localization for all kinds of texts, documents, and web content

First release: February 2026

Mac-128
BetterLocale provides AI-assisted translations for almost any type of content. Whether it is short UI text, longer documents, website content, app copy, or technical documentation, everything is handled in a single central editor so you do not have to switch constantly between different tools.
The app gives you full control over how you want to work. You can create and manage translations entirely manually inside the editor if you prefer maximum control or want to avoid using AI. Alternatively, BetterLocale can generate structured AI prompts that you execute in an external AI client such as ChatGPT. You then paste the result back into the app, without needing to configure an API key inside BetterLocale itself.
If you already have an account with an AI provider, you can trigger translations directly within the app. Currently supported services include OpenAI, DeepL, Gemini, Claude, and Perplexity. You decide which provider to use, can compare results, and choose the option that best fits your tone, quality expectations, or cost requirements.
No matter which workflow you choose, you can always add context, instructions, or style guidelines to ensure the translation matches your target audience and purpose. The app remains flexible and does not force you into rigid formats. It works just as well for quick one-off translations as it does for larger projects across multiple languages.
