Show HN: AI agent that runs real browser workflows (ghostd.io)

4 points by heavymemory ↗ HN
I’ve been experimenting with letting an AI agent execute full workflows in a browser.

In this demo I gave it my CV and asked it to find matching jobs. It scans my inbox, opens the listings, extracts the details and builds a Google Sheet automatically.

I was looking for a similar produc/project the other day. Alas my need is a Linux native version. You may want to consider it as Mac seems to be overserved by the agent harness supply while Linux is the opposite

Cool demo. The tricky bit with browser workflow agents is figuring out which workflows to automate in the first place. Most people don't even realize they're doing the same thing over and over - they just do it.

I've been building MemoryLane (https://github.com/deusXmachina-dev/memorylane) which comes at this from the other side - it records screen activity, spots repeated patterns with AI, and then tells you "hey you keep doing this, want to automate it?" Works as an MCP plugin for Claude/Cursor.

Feels like pattern detection (finding what to automate) + browser agents like yours (actually doing the automation) is the right combo. Are you thinking about the discovery side at all, or mostly focused on execution?

Interesting demo, how are you thinking about prompt injection and security with web agents? Ive been facing this as well.

Nice demo. The prompt injection concern is real for any browser agent in production. We've found that the hybrid approach (deterministic steps + AI for the unpredictable parts) combined with step-level observability is what gives teams confidence to run these unattended. The 'fixed action set' is a good start.

One thing that surprised me while experimenting with agents is how quickly automation runs into the problem of context and memory.

Executing workflows is actually the easy part. The harder problem is deciding what the agent should remember about previous interactions and how that memory should influence future behavior.

Without some form of long-term memory or learning loop, agents often end up behaving more like stateless automation scripts.

It makes me wonder whether the next interesting step for agents isn't just more tools, but systems that can gradually evolve from their interactions with a single user.
