What is Certainly?
Certainly deploys autonomous AI agents that handle customer conversations across web chat, WhatsApp, Instagram, SMS, email, and voice. Instead of scripted decision trees, the agents reason about goals, call tools in your stack, and resolve tickets end to end. The platform connects to Shopify, Zendesk, Salesforce, Gorgias, and 200-plus AI models with automatic failover.
Traditional chatbots break when customers go off-script. Certainly pairs agentic AI with implementation support from Copenhagen, where the company has operated since 2017. Customers like Feastables, Quad Lock, and Fintiba report containment rates above 40% and measurable revenue impact from post-chat purchases.
E-commerce brands, CX teams, and sales organizations use Certainly for customer support, conversational commerce, and internal ops. Starter plans begin at 500 euros per month with conversation-based billing and a 3-month pilot option.
AI Proposal Builder

What is AI Proposal Builder?
AI Proposal Builder is Qwilr's free sales proposal generator that turns a company website URL into an interactive proposal draft. Paste your site, and the tool scans your messaging, offering, and design style, then builds a prospect-ready page using patterns from over 1 million proposals on the Qwilr platform.
Generic proposal templates make every deal look the same. AI Proposal Builder starts from your own website content, so the first draft already matches your brand voice. You can add videos, dynamic pricing cards, and ROI calculators in Qwilr's editor after generation, which is a different workflow than filling a static PDF template from scratch.
Sales reps, agency owners, and SaaS sellers use it to skip the blank page when pitching new deals. Generation is free without a Qwilr account, but editing and sending requires signing into Qwilr, where paid plans start at $35 per user per month on the Starter tier.
