Upload an RFP. Get a full draft back.

Buoyant reads your RFP, extracts every scope item and requirement, then generates a complete proposal inside Microsoft Word—drawing from your past proposals, projects, resumes, and more.

Always human-reviewed. No black-box sending.

Select any paragraph or section and ask Buoyant to rewrite, expand, or tighten it—using your firm’s past proposals and boilerplate as context so the output sounds like your team, not a chatbot.

Works inside the Word taskpane. No copy-pasting between apps.

Your data stays yours.

Engineering firms handle sensitive project data, client information, and proprietary methodologies. We built Buoyant with that in mind.

Encrypted end to end

All data is encrypted in transit and at rest. Your proposals, RFPs, and knowledge base never travel unprotected.

Fully isolated by organization

Every customer's data is kept strictly separate. Your firm's content is never accessible to other organizations.

Your data is never used for training

We do not train AI models on your firm’s data. Your proprietary proposals, resumes, and project histories remain yours alone.

Buoyant brings AI to the tools engineering and consulting firms already use—starting with proposals.
