Building beautiful software @Notion, formerly @Shortwave @Firebase @Google @Microsoft

[Jacob Wenger @_jwngr]

Building core product abstractions at @NotionHQ is challenging because the product has a huge surface area which is, by design, interconnected. But there's a big payoff on the other side once the new composable primitive exists: emergent behaviors "just work" and layers of functionality come "for free."

[Jacob Wenger @_jwngr]

@brian_lovin @NotionHQ Make sure to turn the reasoning up

[Jacob Wenger @_jwngr]

So to vibe code @NotionHQ in 2026 you just need:
- Composable blocks + perms
- Databases w/ row + column perms
- Agents as 1st class primitive
- Hosted Workers for syncs + trusted code
- Hosted frontends over your data
- SDKs, APIs, MCPs, CLIs for all of it

Good luck!

Column permissions are finally here! Your #1 requested feature.

Control exactly who can view and edit each property in your database. So the sensitive stuff can stay private 🔐

Custom blocks are in private alpha and getting more capable every week. DM me if you want to try them.

AI can build a convincing first version of an app pretty quickly. Getting a team to use it is harder. You need to figure out identity, permissions, data, sharing, and how people will make changes together.

I built a custom block that does desk seating right inside Notion.

11 offices. 19 floor plans. 1,496 seats. One place to manage it all.

[Jacob Wenger @_jwngr]

Austin built a desk seating block for our team that respects each viewer's permissions and shares like anything else in Notion. He got to spend his time on solving his problem instead of building an auth or permissions system or figuring out hosting.

Big things are happening directly inside the Notion editor.

The stated product philosophy is basically the exact opposite of “happiness is wanting what you have and not wanting what you don’t have.”

if you wanna know how long we've been working on muse, here's an excerpt from a doc that i wrote for the meta board a year ago in sep 2025

@natfriedman, the whole team & i have been building muse for a long ass time. been a real pleasure to bring that to life for all of you ♥️

What's the wildest bug report you've ever gotten? Here's a memorable one of mine.

Been a tough few years for the “Notion is just a note taking app” crowd

Slack be like “the solution to every problem is channel-shaped”

[Marc Benioff @Benioff]

Don’t code alone. Slack Code is live.
Humans and agents. Same channel. Same work.
Launching today with agents from @AnthropicAI, @github, @Cognition, and @vercel. This is real multiplayer coding. See it at @Dreamforce #DF26

[Stephen Wu @wustep]

Developers: we’re opening up an early alpha for custom blocks.

It’s a new Notion primitive for building interactive blocks that can read your workspaces and databases.

Very early, very experimental, and we’d love to learn from what you build with it!

🧵 to be one of our first alpha testers

[Jacob Wenger @_jwngr]

Ultimately you want consistency more than anything. Officiating should not tilt a game. Prove it with numbers.

[Jacob Wenger @_jwngr]

Eliminate penalties. Missed calls become tie breaker. Every whistled play gets evaluated by VAR. Room is livestreamed on YouTube. Realtime tools to search calls on historically similar plays. Post game report w additional review and analysis.

[Jacob Wenger @_jwngr]

Momentic helps you ship a better product and catch defects faster. They’ve got some fans here at Notion. Great to see them continually iterating on how to verify applications actually work.

[wei-wei @wuweiweiwu]

AI writes all your code. Does it still work?

That's the gap: coding agents are scaling output, but the same with bugs and incidents. The biggest bottleneck is QA: how can you make sure the code your agents just wrote doesn’t break everything?

The best QA are the ones who know everything about your product. Today, we give that knowledge to Momentic’s most capable agent.

Every Linear ticket, every PRD in Notion, every PR - Momentic knows all.

In just the past few weeks, our agents analyzed 70k+ test failures and created 600 tests. Achieving a 73% PR merge rate, and it’s growing fast.

We’re grateful for the trust of our customers, including Notion, Xero, Webflow, Retool, Runway, Bilt, and more.

World Cup group stages are better product for a soccer fan than knockout stages because nothing ends in penalty kicks
