Bidding Architect
Create and manage your bidding systems and conventions
Build, organize, and share your bridge bidding systems with our interactive visual editor. Create full systems or standalone conventions, add variations for different seats and vulnerabilities, and collaborate with your partner.
- Organize your systems and conventions into folders. Rename, duplicate, move, or delete items from the context menu.
- Import a file from community and create an editable copy to build on top of it.
- Guest users can create and edit systems locally in the browser without signing in, but data is stored only on that device.
- Each system is built as a tree of bidding nodes. Click a node to expand it and add child bids.
- Add a meaning or description to each bid, plus optional annotations and color highlights.
- Add free-form text chapters between bidding sequences for notes and explanations.
- Undo and redo are available for all edits. The total bid count is displayed in the toolbar.
- Create variations to define different bidding trees based on seat position (1st, 2nd, 3rd, 4th) and vulnerability.
- When adding a bid, you can choose to insert an opponent bid instead - useful for documenting your agreements after interference.
- Share any system with other users by email. Choose between View (read-only) or Edit permissions.
- Shared systems appear in the recipient's file browser. Multiple users can edit simultaneously with real-time sync.
- Manage or revoke shares from the context menu at any time.
- Save snapshots of your system at any point. Each version is numbered and timestamped.
- View the full version history and restore any previous version.
- Useful for tracking changes over time or reverting experiments.
- Publish your systems to the Community tab so other users can discover and copy them.
- Browse community systems sorted by name, author, date, or popularity. Filter by tags like "Standard American", "Precision", "Acol", and more.
- Copying a community system creates a linked copy that tracks updates - you'll see a badge when the author publishes a new version.
- You can update to the latest version with one click, or make an editable copy to break the link and customize independently.
- Free - Create and edit systems up to 500 nodes. Browse and copy from the community.
- Builder - Removes the 500-node limit so you can build systems of any size.
- Pro - Everything in Builder, plus sharing, version history, community publishing, and linked copies.
Common questions
Yes. When adding a bid, you can choose to insert an opponent bid instead of your own. This lets you document your agreements after overcalls, doubles, and other interference.
Free accounts can create systems with up to 500 nodes. The Builder plan removes this limit so you can build systems of any size. Your existing data is preserved if you downgrade - systems over 500 nodes simply become read-only.
With the Pro plan, you can share any system with other users by email. Choose View (read-only) or Edit permissions. Shared systems appear in the recipient's file browser. Only Pro users can edit shared systems, a non Pro can view them in read-only mode. Multiple Pro users can edit simultaneously with real-time sync.
When you copy a system from the Community, you get a linked copy that tracks the original. When the author publishes a new version, you'll see an "Update available" badge and can update with one click. You can also break the link to customize independently.

No. The Bidding Architect is free to use with a 500-node limit. Advanced features (unlimited nodes, sharing, version history, community) are available through the Builder and Pro subscription plans.
