In their own words
Pergamon
Pergamon generates regulation-based product manuals, labels, and related documentation from product specifications and reference materials. Its AI authoring agent accepts specifications, documents, videos, audio, and images to produce structured manual content, while more than 200 pre-built product blueprints offer structured starting points. Neural machine translation supports 30+ languages and is described as keeping terminology and regulatory structure consistent. Manuals can be exported as PDF, InDesign, HTML, or XML, with formats depending on plan. An optional AI Product Support Agent lets consumers and support teams scan a product and ask questions by voice or text, with answers drawn from its manual. Pergamon offers TMS and ERP/PIM integrations on Enterprise plans, plus API and bespoke integrations for Enterprise clients. It is hosted and runs on Linux, macOS, web, and Windows. Pricing starts at $49/mo; there is a 7-day trial and no free plan. The trial allows one manual with limited, watermarked exports containing partial pages. Pergamon says its data is hosted on AWS servers within the EU and encrypted at rest and in transit. It lists GDPR and ISO 27001 on all plans, while noting brands retain final responsibility for documentation compliance.
Tango
Tango captures work processes and turns them into step-by-step walkthroughs and browser agents. Its browser extension records steps on websites and browser applications without code or flow builders. Walkthroughs can be shared by link, embedded in a website or knowledge base, copied as HTML, or exported as PDF. Guide Me displays step-by-step instructions and highlights where to click. The browser agent interacts with SaaS applications through their front-end interfaces using a Chrome or Edge extension, without API connections or bespoke integrations; Tango names HubSpot and Salesforce as supported examples. The service is cloud-based and does not offer on-premises deployment. Tango says data is encrypted at rest and in transit, and that its AI providers may not retain or use customer data for model training or fine-tuning. Secure Blur and Live Blur help limit sensitive data collection, and editors can permanently redact details in images. A free plan includes five shared workflows and up to 10 users per workspace. Paid plans start at $15/user/mo (annual).
