No subscription. No monthly fees. Pay only for what you use.
Purchased with real money via Stripe. Required for code generation (Tier 3) — any operation that calls an external LLM provider. Also accepted for graph queries and envelope assembly.
1 LCN = 20 NOK. Minimum purchase: 5 LCN (100 NOK).
Earned through contributions. When your queries add value to the shared pattern graph, you earn SYN. Spent automatically on graph queries and envelopes — internal operations that don’t require an external LLM.
Cannot be purchased. SYN cannot pay for LLM calls.
refactor-preview, breaking-change, commit-impact).deprecation-path, risky, review).Three key-delivery modes — pick your tradeoff between privacy, cost, and embedder quality. Every mode surfaces the same graph-expanded result shape (callers, callees, type relations) — the embedding supplies candidates; the graph layer supplies the moat.

LCN covers real costs (LLM providers charge us per token). SYN rewards contributions to the shared knowledge graph — your scan/query activity makes the graph better for everyone.
Graph queries and envelopes fall through to LCN. You can always use the service — SYN just gives you a cheaper path for internal operations.
No. Generation calls external LLM providers that charge in fiat, so it requires LCN. SYN is for internal compute operations only.
When your usage contributes patterns to the shared graph (e.g. a structural pattern gets promoted from your private graph to the shared pattern library), you earn SYN. More contribution mechanisms are coming.
No. Pay-as-you-go only. Your LangCoin balance never expires. No recurring charges.
Unused LangCoin is refundable within 30 days of purchase. Contact support for refunds.
Yes. Local-mode embedding runs on an Ollama instance co-located with our forge-api — your function signatures and docstrings get embedded into vectors in-process and never leave the host. No external provider sees the content, not even us (the operator of the host) beyond infrastructure logs. If your threat model requires stricter isolation than that, the on-prem deployment is the next step — talk to us.
BYOK tenants contribute the compute cost of embedding their own corpus. That contribution translates to a small SYN balance you can spend on future internal operations — searches, envelopes, graph queries. One mSYN per 1,000 tokens embedded keeps the contribution flywheel anchored without over-minting.
