Your marketing strategy lives in 5 files.
Notion page. Slack thread. brief-FINAL-v3.docx. Half-finished prompts copied from a friend's tweet.
Nobody knows which version is real.
Your AI sees a different story every conversation.
I'm building one canvas that fixes that.

Context: 9 years ago I made a free poster of this framework — the Digital Marketing Canvas.
Thousands of downloads. Translated to 13 languages. Used in consulting workshops worldwide.
The poster taught the framework.
The SaaS operates it.

The landing's live. The product is still beta.
What I'm building toward: one canvas → AI context → exported skills → synced for your team and clients. No more drift.
Brutal feedback welcome.
Build-in-public starts now. digitalmarketingcanvas.co/sa…

I've been quietly building the AI-native version for months. Today I shipped the landing.

In the coming weeks, we plan to start testing ads in ChatGPT free and Go tiers.
We’re sharing our principles early on how we’ll approach ads–guided by putting user trust and transparency first as we work to make AI accessible to everyone.
What matters most:
- Responses in ChatGPT will not be influenced by ads.
- Ads are always separate and clearly labeled.
- Your conversations are private from advertisers.
- Plus, Pro, Business, and Enterprise tiers will not have ads.

To preserve chain-of-thought (CoT) monitorability, we must be able to measure it.
We built a framework evaluation suite to measure CoT monitorability — 13 evaluations across 24 environments — so that we can actually tell when models verbalize targeted aspects of their internal reasoning. openai.com/index/evaluating-…

Helping students come up with good startup ideas is like hooking them up to the deck catapult of an aircraft carrier. If you succeed, they're gone. What are they supposed to do, not work on the idea? And working on a startup is incompatible with being a student.

Has anyone experimented with “hidden prompts” in website content for ChatGPT Atlas?
I’m wondering if we can guide how Atlas reasons about a page (summaries, form help, etc.) via hidden metadata / DOM hints.
Curious about experiments, wins, fails 👀

We bootstrapped @TallyForms to $4 million ARR with a tiny team and simplicity as our moat.
Here's how we got here:
1️⃣ Pick a crowded, boring industry with low NPS
2️⃣ Target a specific audience (and ignore the rest)
3️⃣ Talk to users constantly
4️⃣ Build one thing extremely well
5️⃣ Keep. Things. Simple.
Endlessly grateful to everyone who's helping us grow. On our terms, at our pace, with our values intact.
As always, full story on the blog → blog.tally.so/how-we-grew-ta…

gpt-oss is out!
we made an open model that performs at the level of o4-mini and runs on a high-end laptop (WTF!!)
(and a smaller one that runs on a phone).
super proud of the team; big triumph of technology.

New Anthropic research: Persona vectors.
Language models sometimes go haywire and slip into weird and unsettling personas. Why? In a new paper, we find “persona vectors"—neural activity patterns controlling traits like evil, sycophancy, or hallucination.
ALT Our automated pipeline takes as input a personality trait (e.g. “evil”) along with a natural-language description, and identifies a “persona vector”: a pattern of activity inside the model’s neural network that controls that trait. Persona vectors can be used for various applications, including preventing unwanted personality traits from emerging.
