## Continual Engine (CE)

Continual Engine builds AI tooling for a very specific hard problem: making large volumes of digital content accessible without a proportional increase in cost or turnaround time. Its PREP Remediation Suite handles PDFs, Word documents and scanned pages, tagging structure, tables and reading order so files pass WCAG and Section 508 checks. PREP Smart HTML converts PDFs into accessible HTML, while a family of APIs (Accessibility Checker, Auto Tag, PDF Audit) lets teams validate and remediate at scale inside their existing pipelines and CMS or LMS integrations.

The company's Invicta engine specialises in alt text at scale, generating consistent image descriptions across technical disciplines, and its video services cover closed captions, transcripts and extended audio descriptions. ContinuA11Y addresses websites with an accessibility plugin, a colour contrast checker and an audit API for hosted PDFs. Complementary professional services cover PPT accessibility, courseware, VPAT/ACR documentation and ADA Title II work.

Positioning is enterprise and compliance-led: CE markets cost savings of up to 80% and time-to-market reductions of up to 85%, and states ISO, SOC 2 and GDPR alignment. Customers are municipalities, universities, publishers and regulated industries, and pricing is quoted per engagement rather than published as a flat rate.

**Pricing & Plans:** Contact for pricing. Continual Engine does not publish list prices; plans are quoted per engagement based on document volume, service mix (SaaS, API, managed service) and support level. A demo is the usual entry point.

- **PREP Remediation Suite:** Automated remediation for PDFs, Word files and scanned pages, including complex tables, with CMS and LMS integrations and a Canvas LTI app.
- **Invicta Alt-Text API:** Generates consistent, high-quality image descriptions across mathematics, science, engineering and other specialist subjects at publishing scale.
- **Video Accessibility:** Closed captions, transcripts and extended audio descriptions for video and audio content, produced with automated plus human review workflows.
- **Website Accessibility:** ContinuA11Y plugin, colour contrast checker and an audit API for hosted PDFs to find and fix website barriers.
- **Compliance Services:** Specialist services for PPT accessibility, courseware, VPAT/ACR documentation and ADA Title II obligations, backed by human quality assurance.

**Strengths:** Automates painful, high-volume remediation work such as scanned PDFs and complex tables; Covers documents, images, video and websites under one vendor relationship; APIs and CMS/LMS integrations support compliance at enterprise scale; Human review layers on top of AI output, which matters for legal and academic accuracy

**Limitations:** No transparent public pricing, so budgeting requires a sales conversation; Enterprise-oriented setup may be heavier than a small team needs; Deliverable quality and timelines depend on engagement scope rather than self-serve tools

## 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.
