An AI bid-writer priced for employees who can't expense software

What it does Yibiao is an Electron desktop app that generates Chinese tender and bid documents using LLMs. It keeps configs, caches, and outputs in a local workspace, and wraps the whole proposal workflow—outlines, technical writing, image insertion, and post-generation checks—into a single offline-first client. The stack is React, TypeScript, and Vite under the hood.

The interesting bit The author explicitly targets cost: a 200,000-word document reportedly costs under one yuan via DeepSeek Flash, and the app is adapted for a free model called LongCat-2.0-Preview. That positioning—“the OpenClaw of bidding”—is a direct jab at the pricey closed-source competition.

Key highlights

• Deep integrations with DeepSeek, Volcano Ark, and LongCat APIs, plus local-model support via Ollama and LM Studio
• Enterprise knowledge base for recycling historical cases and materials into new proposals
• Background tasks (parsing, generation) persist to disk so you can navigate away without losing progress
• Built-in checks for duplicate content and disqualification risks before submission
• Mermaid diagrams and image-to-Word export for richer technical proposals

Caveats

• The README includes a defensive statement about “issue attacks,” suggesting recent community friction
• Several features, including bid news and advanced collaboration, are noted as still in development
• The interface and documentation are overwhelmingly Chinese; English support appears minimal

Verdict Grab it if you draft Chinese tender documents and want to keep API costs near zero while keeping everything local. If procurement paperwork isn’t your job, this is a very specialized tool to skip.
