Event planners juggle dozens of vendor proposals in different formats. These five AI tools cover the full workflow: drafting proposal decks, comparing vendor submissions, and generating branded visual mockups for client presentations.
Event planners juggle dozens of vendor proposals — caterers, florists, AV teams, venues — each arriving in a different format, with different pricing structures and visual materials. The manual work of organizing, comparing, and presenting all of this is where most planners lose hours every week.
AI tools can streamline three distinct stages of the vendor proposal lifecycle:
No single tool does all three well. This guide picks the best AI tool for each stage, so you can assemble a complete AI-assisted workflow from RFP intake to client presentation.
If your team already lives in Google Slides, Plus AI is the most natural fit. It's an AI add-on that works directly inside Google Slides, generating outlines, individual slides, and rewriting content without forcing you to learn a new interface1.
For vendor proposals, this means you can feed it a rough brief — "create a proposal deck for a corporate gala with three catering options, AV requirements, and a venue overview" — and get a structured outline back in seconds. You stay in the tool your team already knows, and the AI handles the blank-page problem.
Where it shines: Speed of first drafts. If you're producing multiple proposal decks per week for different clients, the outline-generation step alone saves meaningful time.
Where it falls short: It's not a design tool at heart. The slides it generates are functional but won't wow a client the way a purpose-built design platform can. Think of it as a fast starting point, not a finished product.

Beautiful.ai takes the opposite approach: it's a standalone presentation platform built around smart templates that automatically adjust layout and design as you add content2. You drop in text and images, and the software handles spacing, alignment, and visual hierarchy on its own.
For event planners, this solves a real problem. Vendor proposal decks need to look professional — they're often the first impression a client gets of your recommended setup. Beautiful.ai's brand consistency tools let you lock in fonts, colors, and logos so every deck looks like it came from your agency2.
Where it shines: Client-facing polish. If the deck is going in front of a stakeholder who's paying five or six figures for an event, the auto-formatting ensures nothing looks amateurish.
Where it falls short: It's a separate platform, not a Google Slides add-on. Teams that need to collaborate in real time within Google Workspace may find the context-switching friction not worth it for internal drafts.
Here's the stage most planners overlook: once all the vendor proposals come in, someone has to read them, compare pricing, evaluate scope, and summarize the differences. That's a document-analysis task, and it's where Claude excels.
Claude, built by Anthropic, is a large language model known for strong reasoning and a large context window — meaning it can ingest and analyze long documents in a single conversation3. You can upload multiple vendor proposals (catering menus, venue contracts, AV quotes) and ask it to build a comparison table, flag discrepancies in scope, or summarize the key terms of each submission.
Where it shines: Handling volume. If you're comparing five catering proposals that are each 15 pages long, Claude can process all of them and produce a structured comparison in minutes. Its reasoning quality means it catches nuances — like a quote that excludes service staff — that simpler summarizers miss.
Where it falls short: It's a text-in, text-out tool. Claude won't create slides or images. Use it for the analysis layer, then hand the output to Plus AI or Beautiful.ai for presentation.
Vendor proposals are visual. A caterer sends photos of their plated dinners, a florist sends images of centerpieces, a venue sends room shots — and too often these photos are poorly lit, cluttered, or shot on a phone in a hurry.
Photoroom is an AI photo editing tool that handles background removal, AI scene generation, and batch processing4. You can take a quick smartphone shot of a sample table setup, strip the background, and drop it into a clean, professional scene. The batch processing feature means you can clean up an entire folder of vendor photos at once4.
Where it shines: Turning usable-but-rough photos into presentation-ready assets without hiring a photographer or learning Photoshop.
Where it falls short: It's focused on product and object photography. For wide-angle venue shots or complex event spaces, the AI scene generation can look artificial. Best used for individual items — dishes, floral arrangements, decor pieces — rather than full-room photography.
Flair.ai is a dedicated AI design tool that lets you place products into high-quality, branded scenes using a drag-and-drop editor5. While it's marketed primarily toward e-commerce, event planners can use it to create visual mockups of vendor setups — tablescapes, staging configurations, decor layouts — that look polished and on-brand.
The workflow: upload a photo of a specific item (a centerpiece, a chair, a lighting fixture), then use Flair.ai's scene generation to place it in a realistic event setting. The drag-and-drop editor gives you control over composition, and branded assets keep everything consistent across proposals5.
Where it shines: Helping clients visualize a vendor's offering in context. A florist's centerpiece photo placed in a realistic tablescape mockup is far more persuasive than the raw product shot alone.
Where it falls short: There's a learning curve to getting scenes to look natural rather than staged. And like Photoroom, it works best for individual items and composed scenes — not for generating full event floor plans.
The five picks aren't competitors — they address different stages of the same workflow:
| Stage | Tool | What it does |
|---|---|---|
| Proposal deck drafting | Plus AI | Generates slide outlines and drafts inside Google Slides1 |
| Client-facing deck design | Beautiful.ai | Auto-formats polished, brand-consistent presentations2 |
| Vendor proposal analysis | Claude | Compares and summarizes long vendor documents3 |
| Photo cleanup | Photoroom | Removes backgrounds and generates clean product/venue photos4 |
| Visual mockups | Flair.ai | Creates branded scene mockups of vendor setups5 |
A typical workflow might look like this: Claude analyzes and compares incoming vendor proposals → Photoroom cleans up the vendor photos → Flair.ai composes those photos into branded mockups → Plus AI drafts the proposal deck outline → Beautiful.ai produces the final client-facing presentation.
You probably don't need all five. If you only produce a few proposals per month, Plus AI plus Claude covers the essentials. If your agency handles high-volume events where visual presentation is a differentiator, adding Beautiful.ai and Flair.ai makes sense. Photoroom fills in wherever raw vendor photos need polish.
