Introducing Spectra AI
Chat with your analytics—powered by any model you choose.
No more building complex SQL statements or wrestling with filters. Ask your data questions directly, select the model that fits your needs, and receive fully formatted answers and charts instantly.
Choose your LLM provider
Switch providers on the fly. Configure keys for OpenAI (GPT-4o), Anthropic (Claude), or Google (Gemini). You can even run a self-hosted model directly on your own infrastructure for 100% data privacy.
SQL Guard protected execution
Keep your database secure. Our SQL Guard (powered by sqlglot) validates all proposed SQL before running. It restricts execution strictly to safe SELECT queries scoped to your account table, rejecting any administrative, multi-statement, or DML changes automatically.
Zero complex training needed
Spectra AI automatically embeds a hand-crafted data dictionary and metric definitions based on your exact schema. It understands page loads, clicks, custom events, UTM referrals, and session lengths right out of the box with zero manual prompting or model fine-tuning.

Attributions
Refer traffic with confidence.
Account members can generate personal links to share with prospects. When someone opens your link, their anonymous session is tied to you for the next 30 days—no sign-in required from them.
Attribution links can empower your sales team to track the source of new business. Team members can see the revenue each prospect generates.
Step 1
Generate
Any team member creates a personal attribution link in the Spectra dashboard.
Step 2
Share
Send the link to a prospect. It includes an embedded attribution token in the URL.
Step 3
Track
When they visit, their anonymous session is attributed to that member. Activity shows up in the Attributions report.
Attribution is session-based and anonymous: Spectra does not capture personally identifiable information from prospects or link their activity to a real name.
