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.

[Profile (Markdown)](https://openaitools.app/tool/deepl.md) ## Overleaf Copilot Overleaf Copilot solves a very specific friction: academic writers who want ChatGPT's help with their prose, but not the copy-paste loop of opening a chat window, pasting a prompt, pasting their paragraph and pasting the result back into the LaTeX source. The extension attaches a panel to the Overleaf editor, so polishing, grammar checking and translation happen on the text you have selected, in the context of the project you are already working in. The feature set is aimed squarely at research writing. Besides general polishing, it can follow a stated revision instruction, offers a library of academic prompts that can be shared with colleagues, provides writing suggestions for improving a draft, and handles translation with an academic register rather than a conversational one. Results are written straight to the clipboard, and both shortcuts and panel layout are configurable so the tool can fit different writing habits. It is important to be clear about what this is: an independent third-party extension developed by a small team of computer science students, not an official Overleaf product. The developers say user content is not stored and merely passed through to the model. The free tier requires the user's own OpenAI API key, while paid tiers supply access to GPT-3.5 or GPT-4 directly. It reports around 4,000 Chrome users and a 4.8 rating across 22 reviews, and is used at 50+ universities according to the vendor. **Pricing & Plans:** Freemium with a free trial: the Free plan costs nothing forever and uses your own OpenAI API key with practical default agents and prompts. Premium is about $3.9 (¥24.9) per 30 days for unlimited GPT-3.5 and unlimited agents, and Premium+ is about $9.9 (¥59.9) per 30 days for GPT-4 access. Payment runs through Stripe with card, Alipay and WeChat Pay support, and team licences are available on request. - **One-click academic polishing:** Select a passage and have ChatGPT revise it in place, with the option to state the specific revisions you want. - **Bilingual grammar checking:** Checks grammar in both English and Chinese, useful for authors writing in a second language. - **Academic-style translation:** Translates text while preserving academic register and discipline-specific terminology rather than producing generic output. - **Prompt library and custom prompts:** A library of curated academic prompts that you can browse, reuse and share, plus fully custom prompts for your own style. - **Shortcuts, layout and clipboard automation:** Assign keyboard shortcuts to each function, adjust the interface layout and have results copied to the clipboard automatically. **Strengths:** Removes the copy-paste step between ChatGPT and the LaTeX editor; Free tier works with your own OpenAI API key, so there is no mandatory spend; Academic prompt library plus fully custom prompts and shortcuts; Reports 4.8 stars from 22 ratings and use across 50+ universities **Limitations:** Requires a paid tier or your own API key to get the most useful models; Only works inside Overleaf, so it is useless for other LaTeX setups or Word documents; Unofficial third-party tool, so long-term maintenance depends on a small independent team; Not intended for use in exams or where AI assistance is disallowed [Profile (Markdown)](https://openaitools.app/tool/overleaf-copilot.md) ## Frequently Asked Questions ### How do DeepL and Overleaf Copilot compare in monthly traffic?
