Cobrief VS Diffyn

Cobrief's answer

Cobrief is the only AI-powered tender platform that covers the entire bidding workflow — from discovering and evaluating public tenders to writing proposals — in a single tool. Our AI reads full tender documents and extracts key requirements, deadlines and qualification criteria onto a single page, with every claim linked directly to its source in the original documents. Unlike generic AI tools, Cobrief never fabricates information. The platform also includes automated price sheet filling, CV matching, market insights based on 10 years of historical tender data, and real-time notifications via email or Slack. Cobrief is ISO 27001 certified, GDPR compliant, and all data is stored and processed in the EU/EEA.

Tender notifications are included free on all plans, removing the paywall that others charge for. The AI drafts proposal responses up to 80% faster, fills price sheets automatically (saving 5x the time), and matches CVs from your team to tender requirements 10x faster. With 1,500+ companies already using the platform and customers like Knowit, Randstad, Hafslund, Oda and Lyreco, Cobrief is proven at scale across industries. We are also founder-owned, built and designed in Norway, and winner of Virke's Innovation Award 2025.

Cobrief's answer

Bid managers, sales leaders and commercial directors at small, medium and large companies that sell goods or services to the public sector. Our customers range from one-person firms bidding on their first tender to large enterprises like Compass Group managing 300+ tenders per year. The platform is used across industries including IT consulting, staffing, facilities management, construction, healthcare and retail. Cobrief currently serves the Norwegian, Swedish, Danish, Finnish and German public procurement markets.

Diffyn's answer:

Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.

Cobrief's answer

Cobrief was founded in 2023 with a simple observation: public procurement is worth over €800 billion annually in the Nordics and Europe, yet the process is bureaucratic, time-consuming and inaccessible — especially for small and medium-sized businesses. On average, only two suppliers bid on each public tender, meaning governments aren't getting the best value and suppliers are missing out on opportunities. Cobrief was built to change that. By automating the tedious parts of tender work with AI, we level the playing field so companies of all sizes can compete. Our vision is to become the world's leading tender platform — one that brings forward the best suppliers.

Diffyn's answer:

I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.
