Open Comet is a high-fidelity AI agent that lives in your browser’s sidepanel. Unlike basic assistants, it autonomously browses, researches, and executes multi-step workflows across any website. Built on a "Zero-Data" architecture, it keeps your history local while providing enterprise-grade reasoning. Features include high-fidelity execution guards, STORM-inspired research loops, and full support for both Cloud (BYOK) and Local (Ollama) models.
Hi Product Hunt! 👋 I’m Prince, the creator of Open Comet.
Most AI agents today feel 'trapped' behind a chat box, forcing you to copy-paste data back and forth. I built Open Comet to bridge that gap—an agent that actually lives where you work.
My goal was to combine the power of autonomous research with a strict privacy-first architecture. Whether you're a researcher needing deep link exploration or a developer automating repetitive web tasks, Open Comet is designed to stay out of your data and in your flow.
Excited to hear your feedback and answer any questions!
Autonomous AI research agents are where things are headed for anyone doing serious market analysis. I built PolyMind (https://polyminds.netlify.app/) to track large trades on prediction markets using AI-powered alerts, and the hardest part was always the research layer — synthesizing signals from dozens of sources into actionable insight. An autonomous browser agent that can handle deep research tasks across the web would be a game-changer for financial due diligence workflows. How does Open Comet handle source reliability and conflicting information across pages?
Lovely! Can this browse my logged in pages like linkedin ? And take actions on my behalf. Some UX flows especially linkedin is sub-optimal and this can help save me lot time. Thanks.
every autonomous browser agent I've tried hits the same wall eventually - persistent auth sessions and bot detection. curious where this one breaks.
Tried a few browser agents before and the scariest moment is always when it hovers over a "Submit Order" button. Does this one ask before doing something irreversible or do you just trust it and hope?
really appreciate the zero-data architecture and local history storage. most ai tools are just black boxes with your data so keeping it in the browser is a big plus for privacy. definitely going to give the chrome extension a spin today
love that you went with local history storage. too many AI tools are black boxes with your data. curious about the STORM research loops - does it actually follow citation trails and cross-reference sources, or is it more like iterative searching?
Does this work only on Perplexity's Comet browser? Is there an affiliation with them as Open Comet's branding, name and logo is almost 100% on par with Perplexity's - most specifically, their Comet product.
autonomous is doing a lot of work here - the distinction that matters for real adoption is whether it blocks before acting or just does things and logs it.
