## DeckAssistant

DeckAssistant is a Stream Deck plugin built for people who constantly shuttle text between applications and an AI chat. Instead of copying a paragraph, switching windows, pasting and copying the answer back, you select the text and press a mapped key. The plugin sends the selection to the AI with the prompt you configured on that button and returns the result, so the round trip becomes a single physical action.

The plugin pairs with a web application that is designed as a more workable ChatGPT interface. There you get folders to organise chats, custom prompts, message editing, history search, favourites, data export, screenshot export, a prompt library and shareable chats, plus Google lookups and image generation. Conversations started from a Stream Deck button continue in the web app, so the button becomes a shortcut into an organised workspace rather than a disposable one-off query.

Setup follows four steps: create an account, copy the API token from your dashboard, install the plugin and paste the token into a button. It runs on macOS 11 or later, on both Intel and Apple Silicon. The product is developed by Martijn Smit under the Lostdomain label and is licensed with a documented licence agreement, refund policy and terms of service. It is aimed at writers, developers, support staff and anyone who wants a consistent, quick AI workflow rather than ad-hoc prompting.

**Pricing & Plans:** Paid software purchased from the vendor, with a licence agreement and refund policy; discounts have been offered at checkout. See the official pricing page for current plans.

- **Process selected text with one key:** Select text in any app, press a key, and the AI processes it in place — no more copy-pasting into a chat window.
- **Custom prompts per button:** Every button can hold its own prompt; pick from the included examples or write your own for rewriting, translating, summarizing and more.
- **Better ChatGPT web interface:** Continue any conversation in the web app with folders, favourites, history search, message editing and prompt library.
- **Export, search and image generation:** Export chats, export screenshots, run Google lookups and generate images without leaving the conversation.

**Strengths:** Turns text processing into a single keypress in any application; Per-button custom prompts make repeated tasks consistent; Web app adds organisation ChatGPT lacks: folders, search, prompt library; Documented licence, refund policy and terms

**Limitations:** Requires a Stream Deck device and macOS 11 or later; Needs an account and an API token before any button works

## 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.
