## 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.

## TestFit

TestFit is a real estate feasibility platform built for the earliest stage of a development deal — the point where you need to know quickly whether a site is worth pursuing. Instead of waiting weeks for a preconstruction team to produce a first draft, you map a parcel or draw a boundary, choose a typology, and let the software generate a complete, editable site plan with buildings, roads, turning radii, parking and topography. TestFit's own customers describe cutting initial site sizing from three to four weeks down to about ten minutes, and the platform reports usage across 6,200+ users.

The product is organised around three solvers. Site Solver handles automated feasibility and deal evaluation using generative design and detailed building presets. Parking Solver concentrates on surface and structured parking layouts, custom stalls and drive aisles. Urban Planner is the entry point for quick massing work, with 2D and 3D visualisation, road layouts, a yield estimator and unlimited users. Around those sit optional add-ons: Site Intelligence supplies parcel, environmental and zoning data plus 3D terrain and cut-and-fill analysis; Pro Forma live-links financials to the plan and imports your own Excel templates; and the MCP Connection lets you prompt site plans from an AI assistant.

Flipping the traditional workflow matters here — TestFit validates a pro forma against an actual physical layout rather than an assumed one, which is what makes the takeoffs for parking, infrastructure and earthwork worth trusting early. Approved layouts then flow into Revit, SketchUp, AutoCAD, Excel or PDF so the concept work survives into documentation, and live feasibility reports keep consultants and stakeholders aligned. Layouts cover multi-family, single-family, industrial, retail, hotel, data center and parking typologies.

**Pricing & Plans:** Paid, quote-based at the top end. Urban Planner is $75/month and Parking Solver $195/month, both billed monthly; Site Solver starts at $15,000/year and Site Solver Portfolio at $20,000/year, billed annually. Add-ons: Site Intelligence +$150/month, Pro Forma +$170/month, MCP Connection +$100/month.

- **Generative site planning:** Map any parcel or draw custom boundaries, then generate a buildable plan with road layout, turning radii and topography handled so you avoid redesign later.
- **Parking Solver:** Produce optimal surface and structured parking layouts, set custom stalls and drive aisles, and validate parking ratios without manual drafting.
- **Site Intelligence data:** Overlay parcel, environmental and zoning data, model 3D terrain with cut-and-fill analysis, and check power and utilities infrastructure before design assumptions harden.
- **Live-linked pro forma:** Connect financial models directly to your design, with live pro forma figures and import of your own Excel templates, to see whether a deal pencils.
- **Takeoffs and direct integrations:** Generate cost estimates for parking, infrastructure and earthwork early, and push approved layouts to Revit, SketchUp, AutoCAD, Excel or PDF.

**Strengths:** Turns site feasibility from a multi-week exercise into an hours-long loop, enabling far more alternatives per budget; Financials are validated against a real generated layout instead of a rough assumption; Approved plans push straight into Revit, SketchUp, AutoCAD, Excel and PDF, so early work is not throwaway; Comprehensive typology coverage, from multi-family and industrial to data centers and structured parking

**Limitations:** Entry price for automated feasibility starts at $15,000/year, which puts full generative design out of reach for very small teams; Site Intelligence data layers such as parcel, flood zone and zoning coverage vary by country; Training and support are English-only and operate during U.S. business hours; Generative design and detailed typology solutions are gated to the Site Solver tier upward
