By: Robert Soares | The Pitch vs. The Product
"AI will create unique, personalized documents for every single reader!"
You've seen the pitches. AI-powered content engines that generate custom proposals for each prospect. Ebooks that rewrite themselves based on reader behavior. Marketing materials that adapt in real-time.
The gap between that pitch and what actually ships is wide enough to drive a truck through.
What's Actually Happening in 2026
Some of it works. A lot of it is marketing wrapping on old technology.
Here's an honest breakdown:
Working well: Basic personalization, merge fields, conditional content blocks. These aren't even AI, but they get bundled into "AI-powered personalization" packages constantly.
Getting better: AI-generated summaries, smart content recommendations. Useful as assistants, not replacements.
Still mostly hype: Fully autonomous document generation that produces anything you'd actually send to a client.
The skepticism isn't just ours. As one Hacker News commenter put it: "I can spot ai-generated content a mile away, it tends to be incredibly useless so once I spot it, I'll run in the opposite direction." That's your client's reaction if AI writes your proposal and you don't catch the telltale blandness.
What Works Today (And Isn't Actually AI)
Merge Fields
The simplest personalization. Still the most reliable.
"Dear First Name" becomes "Dear Sarah." "Your company, Company Name" becomes "Your company, Acme Corp." Nothing fancy. Works every time. Zero hallucination risk.
Conditional Content Blocks
Show different sections based on audience attributes.
If industry = "Healthcare," show healthcare case study. If company size > 500, show enterprise pricing. If role = "Technical," show API documentation.
You define the rules. The system follows them. This is deterministic, not probabilistic, which means it does exactly what you told it to. AI doesn't enter the picture, and honestly, it doesn't need to.
Dynamic Product Recommendations
"Customers like you also viewed..." is based on browsing history, purchase patterns, or explicit preferences. Not generating new content, just selecting from existing options. This is where AI adds genuine value: pattern matching across large data sets.
Personalized Covers
Same document, different cover page per recipient. "Prepared for Acme Corp" with their logo and the recipient's name. Inside content is identical. The cover feels custom.
This takes 30 seconds to set up and makes a real difference in perceived value. It's also ancient technology dressed up in new packaging when vendors call it "AI personalization."
Where AI Actually Helps (With Caveats)
AI-Generated Summaries
Some tools now generate executive summaries based on recipient profile. Upload a long document. The AI creates a one-page summary highlighting what matters for this specific reader's role and industry.
Quality varies. Sometimes helpful. Sometimes generic. Improving steadily. But "improving steadily" and "ready for client-facing output" are two different things.
Smart Content Selection
AI that recommends which content pieces to include in a package. "For a CFO in manufacturing, we recommend: ROI calculator, manufacturing case study, and financial comparison chart."
Not writing new content. Selecting from a library. Actually useful, because the selection logic gets better with data. This is AI doing what it's good at: sorting through options you've already created.
Adaptive Navigation
Flipbooks that highlight sections based on stated interests. Reader indicates they care about pricing, so the pricing section is pre-opened or highlighted. Not personalized content. Personalized experience. There's a meaningful distinction.
Where AI Falls Short (And Will For a While)
Understanding Your Business
AI doesn't know your product like you do. It doesn't know your competitive positioning, your pricing nuances, or what makes your customers successful. It can fill in Product Name and Feature A. It can't explain why your approach is better for a specific customer's situation.
Another Hacker News user described their experience with LLM output: "I hate what LLM spit out and would never accept the whole output verbatim." They use it iteratively for brainstorming rather than final output. That's the right mental model.
Nuance and Tone
Generic AI content sounds... generic. It lacks the voice that makes your brand distinctive. You might save time on first drafts. But you'll spend that time (and then some) editing for quality. According to a RAND study cited by Gartner, 80-90% of AI projects never leave the pilot phase. Part of the reason is that the gap between demo and production quality is wider than teams expect.
Accuracy
AI hallucinates. It makes things up. In a marketing email, that's embarrassing. In a contract or compliance document, that's dangerous.
Human review isn't optional. It's essential.
Relationship Context
Your best sales proposals reference past conversations, acknowledge specific challenges, and build on established trust. AI doesn't know you had a great conversation about their supply chain challenges last Tuesday. It can't reference the email their CEO sent. The most persuasive parts of a proposal are the parts that prove you listened. AI hasn't been in the room.
Practical Personalization That Works Now
You don't need AI for effective personalization. You need systems.
Template with merge fields. Create your base document. Add merge fields for name, company, and key variables. Thirty minutes of setup. Every document feels addressed to the recipient.
Conditional sections. Create variations for different segments. Industry-specific case studies. Role-specific messaging. Size-appropriate pricing. Set up rules. The right content appears for the right audience. A few hours per template. Content feels relevant to each segment.
Modular content library. Build a library of reusable sections. Assemble custom documents by selecting appropriate modules. Product page A + Case study B + Pricing tier C + Team bio D = custom proposal. Ongoing content development, but highly customized documents with minimal per-document effort.
AI-assisted, with human oversight. Use AI for first drafts, suggestions, and optimization. Human reviews and finalizes everything. Faster creation, maintained quality. This is the only level where AI enters, and it's as an assistant, not the author.
The Honest Advice
Start simple. Pick one document type. Add merge fields. Measure whether it performs better than generic versions. It will. Then expand.
Build your module library. Every case study, product description, and proof point is a potential module. Organize them for easy selection. When you need a custom proposal, you're assembling, not creating from scratch.
If you want to test AI, try it on low-stakes documents first. Always review and edit output. Compare quality to your best human-written versions. Be honest about whether it's actually saving time or just shifting where the time goes.
The personalization that moves the needle in 2026 is mostly the same personalization that worked in 2016. Merge fields, conditional logic, and a well-organized content library. AI makes it faster to assemble. It doesn't make it unnecessary to build.
