## BuildPrompt

BuildPrompt targets the AECO world — architecture, engineering, construction and operations — where project evidence is spread across documents, registers, drawings, spreadsheets and disconnected systems. The platform ingests that material, builds a knowledge graph that links records sharing an anchor such as an asset ID, and runs repeatable 'prompt stack' workflows in which rows are sources and columns are prompts, with every cell returning a typed answer plus its citation.

Rather than acting as a generic chatbot, BuildPrompt frames itself around evidence and auditability. Typical jobs include spotting recurring health and safety risks, catching repeat quality defects before rework, clearing missing evidence ahead of handover, and surfacing portfolio obligations such as charges that may sit with someone else under a lease. Each answer shows where it came from and who should act next.

Deployment is designed around sovereignty and control: the platform runs in your tenant or an agreed secure cloud, works with leading foundation models plus custom or fine-tuned ones, and the vendor states compliance credentials including ISO 27001, Cyber Essentials Plus and Crown Commercial Service supplier status. Pricing is not published; access is arranged through contact with the company, which suits enterprise and public-sector procurement.

**Pricing & Plans:** No public pricing tiers are listed; BuildPrompt is sold through contact with the company, typically as an enterprise or public-sector engagement.

- **Knowledge graph across systems:** Links documents, registers, drawings and databases by shared anchors such as asset IDs, so information that lives apart is understood together.
- **PromptStack workflows:** Turns an objective into a repeatable grid where rows are sources and columns are prompts, and each cell is a typed answer with a citation.
- **Evidence with every answer:** Findings keep a trace back to their source records, so teams can inspect the issue and trust the answer before acting.
- **Built-in evaluation framework:** Agreed checks and review steps let teams test the approach, surface disagreements and keep human review in the loop.
- **Controlled, sovereign deployment:** Runs in your tenant or an agreed secure cloud with your access, security and governance controls, supporting custom or fine-tuned models.

**Strengths:** Answers are deliberately traceable back to source records, which supports audit and assurance work; Designed specifically for AECO data rather than repurposed as a general-purpose chatbot; Sovereign deployment options and recognised compliance credentials suit regulated and public-sector buyers; Works with leading models including custom or fine-tuned ones, avoiding lock-in to a single LLM

**Limitations:** Pricing is not published, so evaluating cost requires contacting sales; Value depends on quality and availability of your existing project data; Enterprise onboarding and deployment take more effort than a self-serve tool

## 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.
