Genspark for Excel is an AI assistant embedded directly inside Microsoft Excel that lets users complete spreadsheet tasks through natural language commands. It writes formulas including advanced array functions and XLOOKUP, builds charts, generates pivot tables, analyzes datasets, and even pulls live web research — all without leaving the spreadsheet. The tool is designed for analysts, operations teams, and business users who live in spreadsheets but don't want to become Excel formula experts. Instead of googling syntax or copying StackOverflow answers, users describe what they need in plain English and the AI translates it into working Excel operations in place. Genspark has been building AI-native productivity tools since 2024. The Excel add-in is their most focused product yet — going deep on a single high-value workflow rather than building a general assistant. With a free tier available, the barrier to trying it is low for any Excel power user.

illumi is an AI visual workspace designed around one thesis: "execution got cheap overnight, but comprehension didn't keep up." The founders argue that modern AI tools accelerate output production but fragment the thinking process — each conversation starts fresh, context gets lost, and knowledge workers spend more time reconstructing mental models than doing actual work. The tool maintains session continuity across work phases: raw notes and messy thinking in early sessions are preserved and connected to the polished deliverables they eventually become. AI assists at each stage — synthesizing scattered notes into structured frameworks, drafting deliverables from frameworks, and flagging when new context contradicts earlier decisions. The workspace is designed to make the evolution of a project's thinking visible, not just its final outputs. illumi launched on Product Hunt on April 21, 2026 with 92 upvotes and sparked one of the more substantive discussions of the week — a thread titled "Is AI making knowledge work harder, not easier?" resonated strongly. A two-founder indie team built it. At this stage it's an early product with a clear POV, targeting knowledge workers who feel increasingly productive but increasingly confused about their own work.
Reviewer scorecard
“I've watched non-technical teammates struggle with XLOOKUP syntax for years. An AI that lives inside the spreadsheet and writes the formula for you in context is genuinely useful — especially since it can see the actual data structure to avoid type mismatches.”
“The problem statement is accurate — I have a graveyard of ChatGPT conversations that led to good decisions I can no longer reconstruct. A tool that preserves the reasoning chain from messy brainstorm to shipping decision is worth trying. Whether illumi actually does that at v1 is the real question.”
“Excel AI add-ins are a crowded category — Copilot in Microsoft 365 does most of this, and it's bundled for enterprise users. Unless the web research pull is meaningfully better than Copilot's, this faces a brutal incumbent.”
“'Session continuity' and 'preserved thinking' are features that require deep integration into how you actually work — and most people won't restructure their workflow around a new tool unless it's dramatically better from day one. The 92 PH upvotes suggest interest, not retention. Come back in six months.”
“The most profound AI applications are the ones that meet users in their existing tools rather than forcing workflow changes. Embedding AI inside Excel — where billions of hours of knowledge work happen — has compounding impact that standalone AI apps can't match.”
“The 'cognitive overhead of AI' problem is real and growing. We're heading toward a world where AI-generated outputs vastly outnumber human-reviewed outputs — tools that make the thinking process durable and auditable aren't productivity luxuries, they're organizational infrastructure.”
“For content creators managing editorial calendars, audience data, and campaign analytics in spreadsheets, this is a practical daily-driver upgrade. Web research pulls inside Excel changes how you build data-backed content briefs.”
“For content strategists and writers who live in the messy middle of multiple projects, a workspace that connects early ideation to final drafts without losing the 'why' behind every decision addresses a daily frustration. The visual approach feels right for how creative thinking actually works.”
