FAQ

Common questions

How is Synaptic different from other productivity tools?+
Other tools forget everything after each session and live in walled gardens. Synaptic has persistent memory across all your work, works with 50+ models simultaneously, connects to your real tools (Gmail, Drive, Slack, Notion), and supports any MCP-compatible server. It's a persistent knowledge workspace, not just another messaging app.
Is my data private and secure?+
Yes. Your data is encrypted at rest and in transit. API keys are stored with Fernet symmetric encryption. We never train on your data. You can delete your memories, chats, and account at any time. OAuth tokens are stored securely and never exposed.
What is BYOK (Bring Your Own Key)?+
You can add your own API keys for OpenAI, Anthropic, Google, and other providers. Your keys are encrypted and used directly — you pay providers at cost with no markup. Full control over costs and model access.
What is MCP and why does it matter?+
MCP (Model Context Protocol) is an open standard that lets intelligent apps connect to external tools and data sources. Synaptic is the first web-based knowledge platform with a built-in MCP Client — meaning you can connect any MCP-compatible server (DeepWiki, GitHub, Linear, Stripe) and Synaptic will automatically discover and use those tools.
What integrations are supported?+
Synaptic integrates with 50+ services including productivity tools, knowledge bases, and any MCP-compatible server. You can bring your own API keys for any supported integration or use our defaults.
Is it free? What are the pricing plans?+
Yes. Synaptic has a Free plan with 20 messages/day and core features. Pro is $20/month (or $16/month billed annually) with unlimited messages, full integration access, document analysis, and more. Max is $100/month for power users who need higher quotas, more tasks, and priority Opus access.
Do I need a credit card to start?+
No. Every new account gets a 14-day Pro trial automatically with no credit card required. If you don't upgrade, your account simply reverts to the Free plan after the trial ends.
Can I upgrade, downgrade, or cancel anytime?+
Yes. You can change plans anytime, and annual plans save 20%. Paid subscriptions are managed from the Billing panel inside the app once LemonSqueezy is fully connected.
