## 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.

## ProofUp

ProofUp is a tenant screening platform built for multifamily property operators who need to confirm that an applicant can actually pay the rent. Instead of trusting whatever pay stub gets uploaded, it verifies income directly: applicants connect their bank and payroll accounts through Plaid, and earnings are read from the account rather than from a document. For those who upload instead, AI reads deposit frequency and actual earnings, which extends coverage to gig workers and guarantors.

The second layer is identity. A government-issued ID is photographed front and back, a live selfie is captured, and facial recognition confirms the two match — addressing the gap between the name on paper and the person who shows up. The third layer examines uploaded documents at the data level, checking file structure, metadata, and generator fingerprints for tampering that looks clean to the eye.

Everything converges into a single verdict per application — one of five, each carrying a risk level and the evidence behind it. Notably, the platform grades evidence quality: a direct bank connection differs from a source-downloaded PDF, which differs from a scan or phone photo. That distinction lets an approval team move fast while a review team still knows which applications deserve a sample. ProofUp positions itself against unverified approvals, which it says default far more often.

**Pricing & Plans:** Contact for pricing. ProofUp does not publish public tiers on its site; pricing is arranged through a demo request and depends on portfolio size and screening requirements.

- **Income verification from the source:** Applicants connect bank and payroll accounts through Plaid so earnings are read from the account itself, with no document in the path to forge. Uploaded documents are also analyzed for deposit frequency and real income.
- **ID plus live selfie matching:** A government ID photographed front and back is matched against a live selfie using facial recognition, catching borrowed identities before keys are handed over.
- **Document forgery detection:** Uploaded PDFs are read at the byte level for hidden text layers, metadata mismatches, generator fingerprints, and post-generation edits — evidence that visual inspection misses.
- **Five graded verdicts with reasons:** Each application returns one of five verdicts (pass, pass with caution, non-recurring, needs review, fail) with a risk level and the specific signals that produced it.
- **Auditable decision trail:** Reports record verification method, document source, per-attempt history, and plain-language flag explanations, so decisions are defensible and reviewable.

**Strengths:** Income is verified from the account via Plaid, so there is no forgeable document in the strongest path; Combines income, identity, and document-fraud checks in a single 2-3 minute flow; Five graded verdicts with explicit reasons and risk levels beat a simple pass/fail; Evidence-quality grading separates source-downloaded PDFs from scans and photos

**Limitations:** No public pricing — you must book a demo to get numbers; Strongest results depend on applicants connecting bank and payroll accounts, which some may resist; Document-level fraud analysis only applies to applicants who upload files rather than connect accounts
