agentic AI with full browser control

a local-first assistant that reads your tabs, navigates pages, runs workflows, and remembers everything across sessions — powered by claude, openai, azure, or ollama.

free, open source (MIT). settings can be changed any time — provider, API keys, autonomy, browser permissions — from the REPL, the web UI, or by editing .env.

while it thinks, you see it think

chika streams its reasoning, tool calls, and plan checklist in real time. no opaque spinners. no "loading…" silence.

what's in the box

browser hands

read DOM, click, fill, screenshot, monitor element changes

workflow engine

10 step types, single-step recovery, auto-continue

plan checklist

verbose patch-editable plans across CLI/frontend/extension

multi-provider

anthropic, openai, azure, ollama; switch via /provider or settings modal

profiles + memory

isolated workspaces, per-profile markdown memory with TTL

auto-update

updates itself on launch when CI is green; opt out with /auto-update off

Windows 10/11 · per-user install · no admin

macOS 12+ · pkg installer · admin required

PyPI

pip install chika

standard pip install when released

update

chika updates itself on launch when upstream CI is green. you don't need to do anything. but if you want to:

from the CLI

chika update
chika update --check
chika doctor

from inside the REPL

/update
/update --check
/auto-update on|off
/doctor

auto-update only applies on a fast-forward to main with all CI green and your working tree clean. never rolls you onto a broken commit.

uninstall

two ways: the os app manager (the one you already know), or chika uninstall.

OS app manager

  • Windows: Settings → Apps → Installed apps → Chika
  • macOS: sudo /Library/Application\ Support/Chika/uninstall.sh
  • Linux (deb): sudo apt remove chika
  • Linux (universal): ~/.local/share/chika/uninstall.sh

CLI

chika uninstall
chika uninstall --yes
chika uninstall --remove-data

user data at ~/.chika/ is preserved by default. delete it manually if you want a clean removal.
