Any AI. Any email. Any system.
Pontius works with whatever you use. No lock-in, no ecosystem traps. Switch AI tools, email providers, or operating systems whenever you want.
The problem with email tools
Most tools lock you into their ecosystem
Gmail-only. Requires their AI. Windows-only. Every constraint is a trap. When you outgrow the tool — or the tool changes — you're stuck rebuilding from scratch.
AI lock-in
“Works with ChatGPT” — until you want Claude. Or Gemini. Or the next breakthrough. Then you start over.
Email lock-in
Gmail integrations that break on Outlook. Proprietary APIs that don't work with Fastmail. Your provider becomes your prison.
Platform lock-in
Mac-only apps. Browser extensions that only work in Chrome. When you switch machines, your workflow doesn't come with you.
“Ultimate freedom, maximum security. You're not locked into an ecosystem, not trusting some startup with your correspondence.”
Pontius uses standard protocols. IMAP/SMTP for email. CLI commands for AI. Pure Go for cross-platform. No proprietary hooks, no ecosystem traps.
No lock-in. Ever.
Use what you want. Switch when you want.
