Comparison
Perplexity built a whole Chromium browser around an assistant. Browsentic takes the other road: it stays inside the browser you already have, with the profile, the logins and the extensions you already trust. Here is where each one wins.
Different owners
A new browser, built around an assistant
An extension in the browser you already have
Side by side
Checked against Perplexity’s own pages and help centre, September 2026. Their product moves; when this drifts, an issue is the fastest fix.
| Browsentic | Comet | |
|---|---|---|
| The shape of it | ||
| What you install | An extension and a local daemon, in the browser you use now | A second browser, then your profile into it |
| Your logins | Already there: it drives the tab in front of you | Imported, then maintained in a second place |
| Where it thinks | Your machine; the daemon binds to loopback | Perplexity’s cloud |
| The agent | Claude Code, Codex or Antigravity, your pick, down to the model | Perplexity’s models |
| What it costs | Nothing beyond the agent subscription you already have | A free tier, Pro at twenty dollars a month, Max at two hundred |
| Source | MIT licensed, source available | Proprietary |
| If it is discontinued | It is yours: the source, the daemon and the extension are on your disk | The browser is the product |
| On the page | ||
| Read, click, type, submit | Yes, and anything consequential asks first | Yes |
| Console and network | Yes: errors, failed requests and timings, over Chrome’s debugger | Not exposed |
| Credentials | Sealed into placeholders; the agent never sees plaintext | Handled by the browser’s own password manager |
| Show it a job once | Recordings: do it yourself, later say “do it like last time” | Describe it again each time |
| Site knowledge | Site maps: it explores any site and keeps notes, intranets included | None kept between tasks |
| Search | None of its own: it drives the pages you already use | An answer engine, and the reason many people install it |
| While you are elsewhere | ||
| Scheduled jobs | Kept in the extension, on your machine | Background assistants, on the Max plan |
| Several agents at once | Several tabs, several agents, one browser, one daemon | One assistant |
| Voice | Dictate in the panel, press to talk in the popup | Voice mode |
| Mobile | No: it needs a desktop Chromium browser | iOS and Android |
No equivalent over there
The hardest part of an AI browser is the day you install it: the profile, the extensions, the passwords, the sessions you would have to sign into again. An extension skips all of it, because you are already in the right browser.
It runs on the CLI you already pay for, and switching between Claude Code, Codex and Antigravity is one click. No second subscription, and no bet on one vendor staying in the browser business.
Atlas shut down in August 2026 and took its browser with it. Browsentic is MIT licensed and runs on your machine, so the worst case is that nobody updates it, not that it stops opening.
Passwords, keys, tokens and card numbers become sealed placeholders before the agent sees them, and turn back into plaintext only inside the field they are typed into.
Record a job yourself and replay it later. Point it at a site and it maps itself. Both become skills you read before you arm them, and both work on an intranet no model has seen.
The same daemon speaks MCP over stdio, so Claude Code, Cursor or Zed can drive the paired tab. One browser, shared by the panel and every client you use.
Credit where it is due
A comparison you cannot lose is not a comparison. These are real, and some of them are why some people should pick their product over ours.
Search, ad blocking, voice and a sidebar that is there before you ask for it. Browsentic has none of that: it is a panel in the browser you already chose.
Comet installs the way a browser installs. Browsentic wants an npx command and a trip through chrome://extensions, and we know that is a worse first five minutes.
Perplexity’s search is the reason many people are there at all, and it is genuinely good. Browsentic does not search: it drives the pages you open yourself.
Comet runs on iOS and Android. Browsentic needs a desktop Chromium browser and a daemon on the same machine, so there is no mobile story at all.
The short version
Pick Comet if you want an AI browser: search, a sidebar and voice in one download, on desktop and mobile, and you are happy to move in.
Pick Browsentic if you want to keep the browser you have, run the agent you already pay for, keep the whole thing on your machine, and own the source.
They can coexist, though there is little reason to run both. If you are trying Comet, Browsentic will drive it too: it is Chromium, so the extension loads.
Free and MIT licensed. No signup, no key to paste, and a fresh install connects to nothing until you pair it yourself.
