Today we’re launching Simular Pro - our first production-grade computer use agent that can use computers like a human.

We built Simular Pro because most AI tools stop at text or APIs. In the real world, workflows often live inside GUIs - spreadsheets, EMRs, CRMs, dashboards - and they change all the time.

Simular Pro currently runs on your mac or macOS virtual machine. It can see the screen, move the mouse, click buttons, type text, and adapt when the UI changes.

How we built it:

Most agents rely purely on LLMs - great explorers, but flaky executors.

RPA tools are stable, but rigid.

Simular Pro combines both to solve the Generality vs. Repeatability problem:

• Neural Agent: explores and adapts.

• Symbolic Agent: locks in what works and executes.

Every action becomes editable, deterministic code — fully transparent and repeatable.

Examples that Simular Pro can do:

1️⃣ Price comparisons on Labubus for my daughter’s birthday → 30 legit options ranked by value in a spreadsheet.

2️⃣ Finding YouTube influencers for Simular’s launch → keyword search, pulled subs/views, ranked top 60 in minutes.

3️⃣ Batch drafting cold emails → pulled leads from CRM, grabbed context, drafted tailored intros; I just reviewed & sent.

4️⃣ Social content from an 18-page paper → drafted an X thread, suggested visuals, loaded into NotebookLLM to spin up a podcast.

5️⃣ Hiring an ex-DeepMind PM → ran LinkedIn search, filtered results, pulled names/roles/schools into a spreadsheet.

6️⃣ End-to-end Xcode build → compiled & packaged app, zipped & uploaded to Google Cloud with auto-update logic.

We’ve seen business customers automate everything from insurance claims processing to healthcare admin to data migration - all without custom integrations.

We’d love your feedback, ideas, and wildest use cases. Drop a comment if there’s something you wish an AI could just handle for you.

@agidude Steve Jobs gave you a big thumbs up, aha

@andrew_jameson111 not sure if he would really like it though lol
David Huang

Sorry probably a super dumb question, how does this differentiate from other agents like manus, genspark, etc.

Ang Li
@david_huang19 there are two types of agents - API agents and GUI agents. Manus is API + virtual browser. Simular Pro is a dedicated GUI agent on desktop which enables your computer to act independently like a digital worker.

@agidude I see, good insight, thanks for the explanation!

Omari.

@david_huang19  @agidude  Well detailed explanation. Thanks.

It reminded me ad of Cadbury. At this particular moment, every marketer should love it. 😀

Ang Li
@busmark_w_nika thanks for your pointer! I didn’t know this ad before but apparently.. gorillas are all you need lol

@agidude yeah, even Robbie Williams acted like a gorilla in this movie: https://www.imdb.com/title/tt14260836/

I used it and it’s really really powerful! It has some learning curve but very well worth learning it
Ang Li
@cocoopenart thank you coco!!!

That’s wild, the demo is beyond cool and this feels like the kind of leap that makes “computers as teammates” real.

Can already imagine the productivity unlock once this hits Windows. Big fan, watching closely!

Ang Li
@dheerajdotexe thank you bro! We are actively working on a windows version. Stay tuned!!

Congrats! Complex dynamic UI elements like pop-ups or multi-layer workflows can disrupt automation reliability. How are you addressing these challenges to ensure repeatable and robust automation?

Ang Li
@vouchy we allow users to insert limited steps of LLM based navigation at any place in the workflow which can help identify accidental popups and close them effectively.

Simular Pro is the first agent I've seen that runs on macOS. I already love it after my first try!

Ang Li
@justin2025 thanks Justin! glad you like it!
Andrew Jameson

Whoa—being able to automate any macOS workflow, even when the UI changes, is wild and interesting

Mcval Osborne

Absolutely love that it works for macOS.

Ang Li
@mcval_osborne Mac is my favorite too!
Jian Lu
Love it! And the intro video is so entertaining!
