Negotiation Tools
Negotiation Visualizer
Chart offers and brackets from both parties to visualize convergence. Numerical offers appear as connected dots; brackets appear as shaded ranges. Overlapping bracket zones are highlighted in green.
How it works
Most negotiations are easier to understand as a picture than as a list of numbers. The Negotiation Visualizer charts a settlement negotiation round by round: enter each offer as it happens, and the chart plots the plaintiff's demands and the defendant's offers as two converging lines.
The tool accepts two kinds of moves. A firm offer is a single number, like 500,000. A bracket is a range, entered like 200,000-400,000, which appears on the chart as a shaded band with a dotted line through its midpoint. When both sides have brackets on the table and the brackets overlap, the overlapping zone is highlighted in green — often the first visible sign of where a deal might land.
Once both sides have made at least three moves, you can turn on a projected convergence point. It fits a straight line through each side's three most recent moves and extends both lines to where they would intersect — the round and the dollar figure where the parties meet if the current pattern simply continues. Negotiations rarely move in straight lines, but the projection is a useful reality check on pace.
Everything runs in your browser. No offer you enter is stored on a server or transmitted anywhere, and you can export the chart and offer history to PDF for your file.
Worked example
Suppose the plaintiff opens at $500,000 and the defendant responds at $100,000. The plaintiff comes down to $400,000; the defendant comes up to $200,000. The plaintiff then offers a bracket of $300,000–$450,000 and the defendant counters with a bracket of $225,000–$325,000. The chart shows the two paths closing, the two brackets overlapping between $300,000 and $325,000 in green, and — with three moves on each side — a projected convergence in the low $300,000s a round or two ahead.
When to use it
Use it live during a mediation to keep a clean record of the bidding, to show a client how far the other side has actually moved, or after a session to study the pattern before the next round. The exported chart also makes a clear exhibit for a client update letter.
Frequently asked questions
How do I enter a bracket in the Negotiation Visualizer?
Type the range with a dash, like 200,000-400,000. The chart draws it as a shaded band with its midpoint marked. The order doesn't matter — the tool sorts the endpoints.
What does the green area on the chart mean?
Green marks where the two sides' brackets overlap. An overlap doesn't guarantee a deal, but it usually means the parties' signaled ranges already contain a common number.
How is the projected convergence calculated?
It is a straight-line projection based on each side's three most recent moves. The tool fits a line through each side's last three offers and extends both lines to their intersection. It appears only after both sides have made at least three offers, and it is a projection of the current pattern — not a prediction.
Is my negotiation data saved anywhere?
No. Offers exist only in your browser for the current session and are never sent to a server. Closing the tab clears them. Use Export as PDF if you want a record.
