Aegis
free · open sourceAegis is a free, MIT-licensed filter that sits between you and hosted chatbots like ChatGPT, Claude, and Gemini, screening prompts and responses by keyword matching plus a local machine-learning classifier. All analysis runs on the device; nothing is sent to external servers. It filters traffic but does not change where inference happens, so the underlying chatbot still sees every prompt it passes.

Trust-minimized
The proxy mode requires installing a root certificate and routing all system traffic through it, which is a permanent decryption point on the machine if the tool is ever compromised or abandoned.

Editor's note
A local filter over remote AI — it changes what reaches the model, not who runs it.

IVPN
A small Gibraltar-based VPN focused on doing less: no logs, no trackers in its apps, anonymous accounts, and payment in cash or Bitcoin. Its marketing is unusually honest about what VPNs cannot do. Open-source apps and regular audits reduce the trust required, but the operator still sits between you and the internet.
Mullvad VPN
A VPN service from Sweden that requires no email or name to sign up: you get a numbered account and can pay with cash or Bitcoin. It shifts trust from your internet provider to one audited operator at a flat price. A VPN hides traffic from your ISP, but Mullvad can still see your connection metadata.
Organic Maps
A maps and turn-by-turn navigation app built on OpenStreetMap data that works fully offline with no account, no ads, and no tracking. Download regions once and navigate without telling anyone where you are going. Map detail and search still lag Google Maps in some regions, and live traffic data does not exist.
Proton VPN
A VPN from the Swiss company behind Proton Mail, with open-source apps, independent audits, and a usable free tier with no data cap. A good first step for moving your traffic out of your internet provider's logs. You are still trusting Proton not to log, and the free tier limits speed and server choice.
