Problem
You're Losing Customers to Prompt Failures You Didn’t Know Existed
Broken prompts don’t always throw errors. They silently return bad outputs that confuse users, inflate cost and drive churn.
No Version History
Teams can’t compare changes or roll back broken prompt edits. When things break, you're left guessing what changed — and when.

No Alerting
You only find out something’s broken when your users do. Without drift detection or usage alerts, silent regressions go unnoticed for days.

Hard to A/B Test Prompts
Without built-in testing or evaluation tools, it’s impossible to compare prompt versions in a structured, repeatable way.

Prompt Drift
Small changes or model updates cause unexpected behavior over time. You won’t know it’s happening until users start seeing inconsistencies — or stop returning.

Token Waste
Unoptimized prompts quietly inflate your LLM costs. You're paying more for outputs that might be irrelevant, bloated, or broke

No Observability
Without full visibility, You can’t see which prompts are running, what’s failing, or why. No metrics, no traceability — just guesswork and growing risk.

FAQ
Frequently Asked Questions
How does prompt versioning work?
Prompt versioning works like Git for your prompts. Each change creates a new version with a unique identifier. You can tag versions, create branches for experiments, compare performance across versions, and roll back to previous versions instantly. You can integrate automated prompt deployment and A/B testing into your existing CI/CD workflows.
Can I import existing prompts from my application?
Yes, you can bulk import prompts via our API, SDK, CLI, or web interface. We also offer custom migration services for enterprises with large prompt libraries.
How does the SDK integrate with my existing AI stack?
Our SDK works as a lightweight wrapper around OpenAI, Anthropic, and other LLM providers. Add one line to log prompts and responses automatically. We also have native integrations with LangChain, LlamaIndex, and other frameworks.
Can I control who has access to my data within Promptial?
Yes, Promptial allows you to set granular access controls, ensuring that only authorized users within your organization can access or modify sensitive data. You can customize permissions based on roles, ensuring that team members have access only to the data they need for their specific tasks.
What measures does Promptial take to ensure data encryption?
Promptial employs state-of-the-art encryption technologies, including SSL/TLS for data in transit and AES-256 for data at rest, ensuring that all your data remains secure and inaccessible to unauthorized parties. This level of encryption safeguards your information, whether it's being sent to or stored on our servers.
