Announcing dots. Dots work 24/7 for you, learn from your feedback, have their own computer, browser and can be connected to over 4k apps in our ecosystem.
They’re powered by Astra our best model yet. Included in your Pro plan, without drawing down on any of your usage. You can even call a dot while it’s working.
We’re getting you started with your primary dot today and soon you’ll be able to create entire teams of them.

Been a bit quiet here because internal Slack has been hilarious lately and because we are all locked in on DevDay. Tuesday will be fun.
efficiency, productivity, speed
we keep worshipping these words like they are what we live for
ship faster
merge more
manage more agents
compress every loop
remove every pause
turn every hour into output
but what is the point of endless production if there is no time left to think deeply?
not react
not optimize
not summarize
not clear the queue
think
to sit with a question long enough that your real intention starts to appear
to find the purpose underneath the motion
to ask whether the thing being accelerated should exist at all
ai could be a new canvas
a way to make strange things
personal things
impossible things
tools, worlds, poems, games, interfaces, films, languages, rituals
things that let more people touch the shape of their own imagination
but instead, so much of it is becoming slop factories
more content
more funnels
more tickets
more fake work pretending to be value
you can merge 2000 prs
you can manage 500 agents
you can wake up to dashboards proving that the machine kept moving while you slept
but what is the point if you only sleep 5 hours a day?
what is the point if you stop talking to other humans?
stop learning about the past?
stop playing?
stop wandering?
stop being surprised?
what is the point if your whole life becomes optimizing the system that is consuming you?
speed is not meaning
scale is not wisdom
automation is not freedom if it only makes everyone run faster
and where are we running?
toward what?
a world where every person becomes a manager of machines, and every machine produces more things no one had the time to truly want?
the danger is not that ai makes us lazy
the danger is that ai makes us endlessly busy
that it gives us infinite production before we have found intention
infinite execution before we have developed taste
infinite motion before we have learned how to be still
maybe the real frontier is not more speed
maybe it is discernment
knowing what not to make
knowing when to stop
knowing when the most productive thing is to sleep, read history, call a friend, play with a cat, walk without tracking it, or stare at the ceiling until the false urgency dissolves
tools should give us more life
not turn life into a tool
if ai is going to matter, it should not just help us produce more
it should help us become more human
more imaginative
more free
otherwise, it’s the same old factory
just without humans

The hardest thing about building @harvey is doing what’s best for our customers despite immense pressure to do what’s easy.
The easy thing would have been to force our customers onto consumption pricing before they were ready and serve them worse models to protect our margins.
We chose to help our customers transition on a timeline that works for them and give them the best models in the meantime, even though it hurt our margins.
This meant optimizing our product through routing, harness improvements, and post-training so we could serve frontier intelligence at an affordable price.
It also meant building the infrastructure for customers to monitor and manage spend: usage dashboards, per-matter cost attribution, spend caps, and ROI reporting.
As a result, we improved our gross margins from -50% to positive in a single quarter despite usage doubling month over month and continuing to serve the best models.
Our philosophy is simple: do what’s best for our customers, even when it’s painful, hurts our margins, or draws criticism from competitors, X, and the press.
We believe the most important part of building a company is earning and keeping your customers’ trust. You do that by doing the hard thing for them, even when it costs you.
