## BrainyAI

BrainyAI is a Chrome browser extension that puts an AI sidebar next to whatever you are reading. Its goal is to cut out page-hopping: instead of opening tabs for ChatGPT, a search engine and a translation tool, you run everything from one sidebar. The extension describes itself as a 'work assistant' covering search, chat, translation, writing and summarization in a single place.

Its headline capability is multi-engine smart search, which lets you query several AI-powered search engines and compare their answers so you can pick the most useful result. Customizable shortcuts take that further: highlight text on a page and BrainyAI can explain it, translate it or rephrase it in one click, which is handy for reading in a second language or simplifying dense material. Interactive AI conversations round out the sidebar with real-time Q&A and idea generation.

The publisher keeps the extension updated (the listing shows version 0.1.6, updated February 2025) and states that it follows recommended Chrome extension practices, holds a good publisher record and does not collect or sell your data for unrelated purposes. BrainyAI is listed as free on the Chrome Web Store and reported a rating of about 4.7 out of 5 from around 31 ratings at the time of our review, with roughly 1,000 users.

**Pricing & Plans:** BrainyAI is listed as free on the Chrome Web Store. Any costs would come from third-party AI accounts or API keys you choose to connect, since the extension itself carries no listed price.

- **Multi-engine smart search:** Query several AI-powered search engines at once so you can compare results and pick the most relevant answers for your task.
- **Customizable text shortcuts:** Select text on any web page and get one-click explanations, translations and rephrasing without leaving the tab.
- **Interactive AI conversations:** Talk to BrainyAI in real time for instant answers, drafting help and brainstorming from the browser sidebar.
- **Summarize and read:** Summarize and read pages more efficiently so long articles and research become quick, digestible reads.
- **Privacy controls:** A transparent privacy policy with opt-in anonymous data collection gives you control over your information.

**Strengths:** Free Chrome extension with a single AI sidebar for chat, search, translation and summarization; Multi-engine smart search lets you compare answers across AI search engines; One-click explain, translate and rephrase for selected text; Respects privacy: opt-in anonymous data collection and no unrelated data selling

**Limitations:** It is a browser extension rather than a standalone app, so it lives inside Chrome; The listing shows a relatively modest user base (about 1,000 users) and its last update was February 2025; Some capabilities depend on signing in and connecting third-party AI accounts or API keys; Advanced usage beyond the sidebar shortcuts may require paid accounts on the underlying AI services

## 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.
