What every plan buys.
Pay per message
Credits map to messages, not seats. A quick question costs a quick question — heavy sessions cost what they use, and unused months stay cheap.
Every frontier model
GPT, Claude, Gemini, Grok, Llama, DeepSeek and the rest behind one composer and one subscription. Switch mid-thread without losing the conversation.
Bring your own keys
Plug in your own provider API keys and Synapse routes through them directly — your credits stop counting while your keys do the work.
Memory that compounds
Every plan includes cross-conversation memory. Your preferences, projects, and context carry forward — the product gets sharper the longer you use it.
/faq
Fair questions.
How do credits actually work?
Each message reserves credits up front, routes to the model, then commits only what the turn actually used — anything unused refunds straight back to your balance. You never pay for a response that didn't happen.
Which models are included?
GPT, Claude, Gemini, Grok, Llama, Mistral, DeepSeek and more — 20+ frontier models behind one composer. You can switch models mid-thread and the whole conversation carries over.
What changes when I bring my own keys?
Plug in your own OpenAI, Anthropic, or Google API keys and Synapse routes straight through them. Your credit meter idles while your keys do the work — you only spend credits on models you don't have keys for.
Is memory a paid add-on?
No. Cross-conversation memory ships on every plan, including free. What Synapse remembers is visible, scoped to you, and deletable at any time.
Do I need a card to start?
No. The free tier includes monthly chat credits with no card on file. Upgrade only when you hit the ceiling — your threads and memory come with you.
Is yearly billing cheaper?
Yes — yearly works out to roughly 17% off versus paying month to month. You can flip between cycles with the toggle above before you choose a plan.
