persīv Codex
at cost, or for free.
A VS Code-based editor with a built-in local model, use your own API keys with no proxy, and persistent AI memory. Your code stays on your machine or goes straight to your provider. Nothing in between.
Windows & Linux coming soon · Free with the local model, forever
Four things that matter.
Local Model Included
On-device AI. No account. No internet. No cost.
Looking Glass is a 1.7B parameter model shipped with every copy of persīv. It runs entirely on your hardware — Apple Silicon optimized, fast enough for real work. Open the app, start coding. Nothing to configure.
Bring Your Own Keys
Your keys. Direct connection. Nothing routed through us.
API calls go straight from your machine to Anthropic or OpenAI. No proxy, no relay, no intermediary server. Your prompts and code never touch our infrastructure. You pay the provider at their listed price — we don't see the request and we don't take a cut.
Memory Crystals
Persistent context that loads before you type a word.
Save architectural decisions, prompt patterns, and project conventions as named memory. Your AI reads them at the start of every session. No re-explaining your codebase. No drift between conversations.
Real-Time Cost Tracking
Every token. Every dollar. Every team member. Live.
Token-level spend attribution by model, project, and person — updated in real time as requests flow. Set budget ceilings at the org, team, or individual level. Exportable audit trails. You always know exactly where you stand.
Meet Looking Glass.
A compact language model built for local inference. 1.7 billion parameters, optimized for Apple Silicon, runs without internet. Good for boilerplate, explanations, tests, commit messages, and quick iteration. Not a replacement for the large cloud models — a complement to them.
