BYOK · Custom API

Your keys, your models
60+ providers, swappable anytime

Drop in the API keys you already own: OpenAI, Anthropic, Gemini, DeepSeek, xAI, plus any OpenAI- or Anthropic-compatible endpoint or self-hosted relay. Keys are AES-encrypted on device, requests go straight to the provider, you pay provider prices — the app never sees your key.

Key in, ping tested, models toggled — thirty seconds

Switch providers on the left; paste the key, hit “Test” for a real round-trip latency, filter models by modality, and set defaults on the right. This iPad is a live prototype — every step is tappable.

Keys live in the on-device keystore only — no relay

BYOK's security boundary, spelled out

  • On-device onlyKeys are AES-encrypted in secure storage on your phone — never uploaded, never logged, never in telemetry.
  • Direct to providerRequests leave your phone for the apiHost you configured. No resale proxy in between; you pay provider list price.
  • Versioned endpointsapiHost carries the full version prefix, so any OpenAI / Anthropic style endpoint or self-hosted gateway works.
  • Transparent usageEvery request logs model, tokens, cache hits and cost into the API request record for audit anytime.

FAQ

Common questions

Which providers and endpoints are supported?

60+ presets including OpenAI, Anthropic, Google Gemini, DeepSeek, xAI, Mistral, Groq; any OpenAI- or Anthropic-compatible endpoint (including one-api / new-api relays) can join as a custom provider.

Is my API key ever uploaded?

No. Keys are AES-encrypted in on-device secure storage and requests go directly to the provider — Foreverse servers never touch your key.

How do I know a model actually works?

Every provider page has a Test button that fires a real request and shows round-trip latency; the model list filters by text / image / speech / video and toggles take effect immediately.

Can I use it without my own keys?

Yes. The official channel offers metered built-in models (1 credit = $0.0001). Start official, switch to BYOK later — your data stays put.
