Simple credits.
Clear expectations.

Preview information · October 30, 2026

Unbind provides text chat through an external model provider. Free usage is subject to verification, limits and the shared provider budget. Live deposits remain disabled. This page describes the product rules; final operator details and live service terms must be completed before activation.

Free prompts

An eligible browser guest receives five lifetime Flash prompts by default. The owner can configure a lower allowance. Prompts have input/output limits, verification and rate controls, and a shared trial budget. There is no daily reset or guarantee that a browser corresponds to a unique person.

How usage is priced

Initial retail prices per million tokens are: Max $3 uncached input, $0.30 cached input, and $5 output; Flash $1 uncached input, $0.10 cached input, and $2 output. Provider-reported cached input replaces ordinary input billing for those tokens. Conversation history sent again is billable input. These retail prices are separate from unknown upstream costs.

A conservative maximum charge is held before a paid reply. Final reported usage determines the charge, and unused funds are released. If usage is missing, the hold remains pending for reconciliation. Regenerating is a new request with a new charge or trial use. Stop hides further streamed output; the upstream request may continue and incur charges while final usage is collected.

Deposits and valuation

After activation, only SOL and native USDC on Solana mainnet-beta are supported. A $5 USDC payment buys $5 of usage credits. SOL deposits use a persisted USD valuation tied to the finalized transaction time, subject to the documented source and freshness checks. Outages leave a deposit pending instead of inventing a price. The sender pays their network fees; the app separately accounts for its sweep fees and necessary account costs.

Credits are spend-only access to AI usage. They are nonwithdrawable, cannot be transferred to another guest, and are not a custodial balance available for withdrawal. Treasury sweeps do not remove purchased credits or automatically buy inference-provider credit.

Protect your access

Link a wallet before depositing if you want access from another browser. A guest who loses an unlinked session loses access to their chats and balance. The original ledger and deposit mapping remain intact; they are not reassigned.

Limits of the service

AI responses can be inaccurate. No capability, uptime, benchmark, or guaranteed non-refusal claim is made. Text is the only supported input and output. Scoped Unbind API keys support single-turn text requests and share the guest allowance and service budget. There are no subscriptions, uploads, autonomous tools or user withdrawals.
