What is Tendrex?

Tendrex is an AI-powered platform that helps organisations discover, respond to, and win tenders faster. It combines live UK procurement portal search, document ingestion, AI-generated answers with a priority-based RAG pipeline, a structured review workflow, AI-assisted editing, compliance tracking, reusable templates, customisable dashboards, webhooks, a public REST API, and a comprehensive audit trail into a single application.

Why Tendrex?

Tendrex is built for bid teams, proposal managers, and subject-matter experts who regularly respond to tenders, RFPs, ITTs, and questionnaires.

Speed

Reduce draft time by up to 80% using context-aware AI with a priority chain: canonical answers, historical responses, then RAG. Six AI editing transformations help you refine answers instantly.

Accuracy

Answers are grounded in your documents with clear citations, confidence scores, and highlighted source excerpts. Threaded comments and version history ensure nothing is missed.

Collaboration

Five user roles, specialist teams with AI auto-classification, personal queues, in-app notifications, and customisable dashboards for every role.

Knowledge

Build a compounding library of approved answers. Promote the best to canonical status for consistent reuse. Reusable tender templates capture your best structures.

Key Features

Tender Discovery

Search live UK procurement portals — Contracts Finder, Find a Tender, Public Contracts Scotland, and Sell2Wales — from within Tendrex. Filter by category, value, region, and buyer. Bookmark opportunities and import them directly into your portfolio with metadata pre-populated.

AI-Generated Answers

Upload tender questions and receive draft responses grounded in your source documents, policies, and previous submissions. The AI uses a priority chain - checking your canonical answer library first, then historical tender responses, then RAG from uploaded documents - so answers improve with every tender you complete.

AI-Assisted Editing

Refine any answer with six AI-powered transformations: Improve grammar and clarity, Expand with detail and examples, Condense to key points, Formalise to UK public sector tone, convert to Bullet Points, or Strengthen with evidence and commitments.

Smart Review Workflow

A dedicated full-screen review page with split panel, keyboard shortcuts, and inline document viewer. Approve, edit, reject, provide custom answers, or assign to team members. Every answer includes confidence scoring (High/Medium/Low), threaded comments with highlighting and resolution, and a full version history with diff view.

Tender Lifecycle Management

Track tenders from identification through bid/no-bid decisions, active response drafting, review, submission, and outcome recording. Capture client details, contacts, portal information, estimated value, contract duration, lots, and tags. Export completed tenders to DOCX or PDF for submission.

Tender Templates

Create reusable templates from your best tenders to standardise question structures, compliance presets, and default team assignments. Apply a template when creating a new tender to hit the ground running.

Compliance Tracking

Manage compliance items per tender across categories like Legal, Financial, Insurance, Quality, Social Value, Sustainability, Health & Safety, and Data Protection. Track status, assign owners, upload evidence, and apply pre-built UK compliance templates.

Growing Answer Library

Every approved answer is saved, indexed, and searchable. Promote answers to canonical status so the AI prioritises them for similar future questions. Filter by source type (Manual/AI), confidence level, and export to Excel.

Customisable Dashboards

Over 30 widget types covering metrics, lists, and charts - from pipeline value and win rate to team workload and deadline calendars. Drag-and-drop layout, widget resizing, role-based defaults, and multiple dashboards per user.

Teams & Role-Based Access

Five user roles - Admin, Bid Manager, SME, Reviewer, and Viewer - each with a personalised dashboard. Create specialist teams with expertise tags (Security, Legal, Commercial, ESG, Technical, Operations, HR). AI auto-classifies questions and routes them to the right team. In-app notifications keep everyone informed.

Audit & Governance

Comprehensive audit logging for every action - answer generation, reviews, assignments, tender changes, user management, and SSO logins. View per-entity audit trails or browse the org-wide audit log with filtering and pagination.

Developer Tools & Integrations

A public REST API with API key authentication for external integrations. Event-driven webhooks notify your systems when tenders, answers, compliance items, users, or documents change. An in-app API playground lets you test endpoints directly.

Global Search

Press Cmd+K (or Ctrl+K) to search across tenders, teams, the knowledge library, and pages from anywhere in the app.

Secure & Private

Multi-tenant data isolation with organisation-level separation. Microsoft Entra ID (Azure AD) SSO with auto-provisioning. Role-based access control enforced across all API endpoints. Custom org branding with logos, colours, and display names.

The Workflow

1. Discover & Import: Search live UK procurement portals for opportunities, or create a tender manually. Import tenders directly with metadata pre-populated. Build your knowledge base by uploading reference documents (PDF, Word).
2. Upload Questions: Upload the question file (Excel with multi-sheet support, or Word). AI auto-classifies columns including weighting and word limits, extracts metadata, and routes questions to teams.
3. Generate & Refine: AI drafts answers with citations and confidence scores. Use AI-assisted editing to improve, expand, condense, or strengthen answers. Your team reviews in a dedicated full-screen interface with threaded comments and source traceability.
4. Track & Export: Manage compliance items, track progress on customisable dashboards, and export to DOCX or PDF for submission. Approved answers join your canonical library - the AI gets smarter with every tender.
