## AI Localizer

AI Localizer is built for Apple developers who want their app in many languages but don't want to hand-edit string files for weeks. The app loads your Xcode project, detects every localizable string across SwiftUI views, Storyboards, XIBs, legacy .strings files and modern .xcstrings catalogs, and then produces translations you can push directly back into the project with a click.

You are not locked into a single engine. AI Localizer ships with its own AI translation service, and it can also be pointed at your own Microsoft Azure Translator or Google Translate account if your team already has contracts, glossaries or review workflows with those providers. Every translated string is editable inside the app, so a native reviewer can fix tone and terminology without ever opening a code editor.

For teams that need sign-off before shipping, the tool exports translations to CSV for human proofreading and then imports the corrected file back, merging edits into the Xcode project. Wide Angle Software emphasises that only strings are sent to the translation service you choose, and the vendor does not collect your project data. AI Localizer requires macOS 12 or later, and the current build is stated as compatible with macOS 26.

**Pricing & Plans:** Paid desktop product sold as a licence through the Wide Angle Software store; a free trial of the app is typically offered so you can test it on a real project before buying.

- **Automatic string discovery:** Loads an Xcode project and finds every localizable string across SwiftUI, Storyboard, XIB, .strings and .xcstrings resources, so nothing is missed before translation starts.
- **Translate into up to 37 languages:** Pick your target locales from a list covering more than 35 languages and generate the whole translated resource set in one pass.
- **Choose your translation engine:** Use the built-in AI translation service, or plug in your own Microsoft Azure Translator or Google Translate credentials to reuse existing accounts and glossaries.
- **In-app manual editing:** Click any translated string and type over it, which lets fluent reviewers polish tone and terminology without touching Xcode's editors.
- **CSV export and re-import:** Export the full translation table to CSV for human proofreading, then import the corrected file back and merge the changes automatically.
- **Instant project write-back:** Accepted translations are saved straight into the Xcode project, so the localized resources are ready to build with no copy-paste step.

**Strengths:** Handles every Xcode localization format in one tool, including modern .xcstrings catalogs; Works with your own Azure or Google Translate account, so you are not forced onto a single vendor; Nothing is locked in the app: strings can be edited by hand and round-tripped through CSV for review; Runs natively on macOS and writes results straight back into the project

**Limitations:** macOS only, so Windows and Linux developers need a different workflow; Requires macOS 12 or later, which rules out older Macs

## DeepL

DeepL is a specialist Language AI company widely recognized by professional translators, localization managers, and multinational enterprises for delivering more natural, idiomatic translations than general-purpose search translators or raw foundational LLMs. Headquartered in Cologne, Germany, DeepL trains proprietary neural networks and specialized language models tuned specifically for cross-lingual nuance, register, and domain accuracy across more than 30 languages. Over 200,000 businesses globally rely on DeepL to handle sensitive legal, technical, financial, and marketing communications.

The platform spans three integrated product pillars: DeepL Translator, DeepL Write, and DeepL Voice. DeepL Translator handles instant text translation and full-document conversion—preserving exact typography, embedded images, and page layouts across PDF, Microsoft Word (.docx), PowerPoint (.pptx), and Excel (.xlsx) files up to 100 MB. Through its Customization Hub, teams enforce corporate terminology using Shared Glossaries, Translation Memory, and Shared Style Rule Lists, while interactive Clarify prompts resolve source-text ambiguities. DeepL Write Pro acts as an AI writing co-pilot that refines tone, fluency, and audience adaptation in real time, and DeepL Voice delivers live multilingual captions and speech-to-speech translation for virtual meetings and face-to-face conversations.

DeepL offers a Free web and app tier capped at 50,000 characters and one 5 MB file per month, where submitted text may be used to train public models. For strict confidentiality—including immediate text deletion after translation, zero data training, ISO 27001 certification, and SOC 2 Type II compliance—users upgrade to DeepL Pro. In its current tier structure (which replaced legacy Starter, Advanced, and Ultimate naming), Individual costs $8.74/month (€7.49/month billed annually) for 300,000 characters and 3 files/month; Team costs $28.74/user/month (€24.99/month) for 1M characters, 20 files, and shared style rules; and Business costs $57.49/user/month (€49.99/month) for unlimited text translation, 100 files/month, Translation Memory, and bundled DeepL Write Pro.

**Pricing & Plans:** Offers a Free tier (50,000 characters/month and 1 file up to 5 MB); paid DeepL Pro plans billed annually are Individual at $8.74/month (€7.49/month), Team at $28.74/user/month (€24.99/user/month), and Business at $57.49/user/month (€49.99/user/month, which bundles DeepL Write Pro), plus custom Enterprise and metered API plans. All paid Translator plans include 30 minutes/user/month of DeepL Voice.

- **Layout-Preserving Document Translation:** Translates whole PDF, Word (.docx), PowerPoint (.pptx), Excel (.xlsx), and HTML files up to 30 MB (Individual/Team) or 100 MB (Business/Enterprise) while keeping original fonts, tables, slides, and visual formatting intact.
- **Customization Hub: Glossaries, Style Rules & Translation Memory:** Ensures consistent brand and technical terminology across language pairs using CSV-importable shared glossaries, automated glossary generation, shared style rule lists, and translation memory.
- **DeepL Write Pro AI Writing Assistant:** Enhances original drafts and translated copy with real-time sentence rewrites, word alternatives, and one-click tone adjustments (e.g., Business, Academic, Casual, Diplomatic) via browser, desktop, and Microsoft 365/Google Workspace add-ins.
- **DeepL Voice for Meetings & Conversations:** Provides real-time spoken language translation and live multilingual captions for video conferences and mobile in-person dialogues, with 30 minutes per user per month included in paid DeepL Pro plans.
- **Zero-Retention Enterprise Security & BYOK:** Guarantees that Pro subscriber texts are never stored or used for AI model training, backed by ISO 27001-certified European data centers, SOC 2 Type II compliance, SAML SSO, SCIM provisioning, and Enterprise Bring Your Own Key (BYOK) encryption.

**Strengths:** Consistently outperforms generic machine translators in idiomatic fluency, register control (formal vs. informal), and specialized European and Asian language pairs.; Best-in-class document translation preserves intricate PowerPoint, Word, and PDF formatting without manual desktop publishing rework.; Uncompromising enterprise privacy posture with immediate deletion of Pro translations, no model training on customer data, and optional BYOK encryption.; Unified ecosystem combining text translation, DeepL Write Pro stylistic editing, and 30 monthly minutes of DeepL Voice in standard Pro seats.

**Limitations:** TheIndividual plan ($8.74/mo / €7.49/mo) is capped at 300,000 characters and just 3 file translations per month, requiring a jump to Team ($28.74/mo) or Business ($57.49/mo) for heavy workloads.; Supports roughly 30+ core languages, which is significantly narrower than Google Translate's 130+ language catalog for rare regional dialects.; DeepL Write Pro requires an extra €6.99/user/month add-on for Individual and Team subscribers unless upgrading to the Business tier.
