Proposal Builder Agent
Turns a client brief into a structured proposal, then self-reviews it for gaps.
By Mark Barclay · Last updated
Most lost proposals were lost at the scoping stage, not the pricing stage. This agent separates what is included from what is excluded, then argues against its own draft to find the gaps a client would exploit later.
Key takeaways
- •Splits every deliverable into what's included and what's explicitly excluded.
- •Runs a self-review pass that flags scope and payment risk.
- •Surfaces the assumptions you'd otherwise discover mid-project.
- •Writes the full document only after you approve the structure.

How does the Proposal Builder Agent actually run?
It runs as a pipeline, not a conversation. When you press run, the agent works through 4 steps on SynaBot's servers and returns a structured deliverable rather than a chat reply.

- 3Building timeline and assumptions
- 4Self-reviewing for gaps and risk
How do I use the Proposal Builder Agent?
- 1.Paste the client brief in their words or yours.
- 2.List the scope as bullets — one deliverable per line.
- 3.Add pricing and timeline if you have them.
- 4.Review the risk flags, then approve to generate the full proposal.
What's the difference between an AI Agent and an AI Assistant?
An AI Assistant is a conversation: you ask, it answers. An AI Agent is a program: you give it an input, it executes a multi-step plan on its own — fetching, extracting, scoring, drafting — and returns a finished deliverable. Where the Proposal Builder Agent would produce something you'd send or publish, it stops and waits for your approval first.
Is it safe to use with business data?
Yes, within sensible limits. The agent only sees what you paste or the public URLs you supply, it runs on business-tier models that don't train on your inputs, and it never gains write access to your systems. Any draft it produces stays on your screen until you choose to use it. Don't paste anything you wouldn't share with an external consultant.
