Introducing Commentary Writer: AI That Goes Deeper on Your Data

We're excited to announce that today we're launching Commentary Writer, the first AI feature and it changes how you create commentary for your reports.

The Problem We Saw

AI in finance is everywhere. ChatGPT. Claude. Copilot. Every tool promises to write your commentary for you.

But when we spoke to finance leaders who actually tried using these tools, we heard the same things:

"I would never send that to my CEO without completely rewriting it."

"It just restates what's already visible in the charts."

"I have no idea where it got that number from."

The problem wasn't speed. It was trust.

When we interviewed 20 finance leaders who regularly present to CEOs, boards, and clients, 100% said they'd review AI commentary before sharing it externally.

Every single one.

Because when your name is on the report and someone asks, "Where did this number come from?" you need to know the answer.

Generic AI can't give you that. It doesn't understand your business goals. It can't show you where numbers came from. And it gives you summaries anyone could write by glancing at your charts.

Why We Took Our Time

We could have rushed something to market in 2023. Everyone else did.

But we knew generic AI wasn't good enough for the work that actually matters (board packs, investor updates, client reports). The moments where credibility is everything.

After countless conversations with customers, gathering feedback and deep research into areas of existing tools fell short, so we built something different.

What Makes Commentary Writer Different

Business Context

Generic AI doesn't know your goals, your strategy, or your market conditions. So it gives you generic insights.

Commentary Writer is different. You set your business context once (your goals, your strategy, your priorities, your current challenges). And Commentary Writer uses that context in every report.

Not "Revenue increased 8%."

But "Revenue increased 8%, slightly below the 10% target due to delayed product launch in Q1."

That's the difference between narration and insight. Between describing what happened and explaining why it matters.

85% of finance leaders told us business context would make AI genuinely valuable. "That would be the holy grail," one CFO said.

So we built it in.

‍Symbolic Attribution

When you hover over any figure in Commentary Writer, you see the source data, how it was calculated, and the logic behind the conclusion.

We call this Symbolic Attribution. And it's what makes Commentary Writer AI you can actually trust.

Before you share a report with your board, your client, or your CEO, you can verify every single number. No black box. Full traceability.

This is what separates Commentary Writer from ChatGPT, Claude, and every other AI tool.

You can show your work.

Report Context

Your business doesn't operate in a vacuum. Seasonal trends, strategic shifts, market conditions, one-off events...they all change what your numbers mean.

That's why Commentary Writer includes Report Context. For each reporting period, you can add notes about what's happening: "Q4 includes holiday sales spike" or "Launched new product line in March" or "Paused hiring in February."

Commentary Writer adapts its insights to reflect that context. Because the same variance means different things in different situations. Your AI should understand that.

63% of finance leaders told us they're frustrated with AI that simply restates what's already visible. They need insights that go deeper.
