CSI Pro

CSI Pro is a browser-based toolkit for customer-success teams that need renewal-risk analysis and structured account preparation without depending on a continuously connected service. It suits lean teams and privacy-conscious operators who value local, offline workflows. The main trade-off is a focused feature set rather than a complete customer-success operations platform.

Overview

CSI Pro converts usage trends, support volume, and sentiment into a renewal-probability score from 0–100%. That gives account teams a single signal for prioritizing reviews, while the surrounding QBR, triage, advisor, and escalation tools turn the assessment into working material. Core scoring and analysis do not require AI and continue to work offline.

The product is delivered as one HTML file running in a browser, so it is lightweight to deploy and usable without a server connection for its core workflows. Its value is greatest when a team wants a compact renewal-analysis workbench, not a broad system for managing every customer-success process.

Key features

Renewal scoring and customer documents

The score combines three practical signal groups—product usage, support volume, and sentiment—into a probability estimate. It is a useful prioritization aid, but it remains an estimate rather than a replacement for account judgment. CSI Pro also produces structured QBR drafts and one-page escalation briefs, giving teams repeatable starting points for reviews and urgent issue summaries. Pro is required for AI-enhanced versions of these outputs.

Account Intelligence and Document Vault

Account Intelligence brings together company news, financial signals, and customer-success community data. The free allowance is three research uses, with Wikipedia as a fallback when no API key is available. Pro adds a Document Vault that accepts PDF, CSV, and TXT files and uses their contents to inform QBR, triage, and advisor outputs. That is a meaningful advantage for teams whose account context lives in internal files rather than only in external research.

AI choices and offline operation

Supported providers include OpenRouter, Anthropic, Google Gemini, Ollama, OpenAI, and generic OpenAI-compatible endpoints. The free Zero-Config AI Bridge instead copies a pre-filled prompt for ChatGPT, Claude, or Gemini, so users can work without placing an API key in CSI Pro. Core scoring, QBR, triage, and advisor features remain available offline, while connected research and provider-based generation are naturally relevant to the paid workflow.

Security and privacy

Account data stays locally in the browser, and stored API keys use AES-256-GCM with PBKDF2 at 100,000 iterations. The maker says it uses no analytics, cookies, third-party tracking scripts, crash reporting, or server-side data collection. Those choices will appeal to organizations that prefer local handling, although teams still need to manage browser storage and device access responsibly.

Pricing

The free plan is the sensible starting point for individual reviewers or teams that only need offline scoring and occasional research. Pro is a one-time purchase rather than a subscription and is aimed at users who need document-informed outputs and expanded intelligence. The license is for internal business use and permits two devices simultaneously, so larger teams or broader deployment may need a different arrangement. Pro research quotas are five Perplexity searches per day and 2,000 Brave searches per month. A free trial is available.

Platforms

CSI Pro runs on the web in Chrome 90+, Firefox 88+, Safari 14+, and Edge 90+. Its single-file browser format supports offline use for the core workflow, making it suitable where installing a conventional desktop application or maintaining a hosted service is undesirable.

Who it's for

Choose CSI Pro if your customer-success work centers on renewal-risk prioritization, QBR preparation, escalation summaries, and account research, especially when local data handling and offline access matter. Pro is the better fit for teams that need internal PDFs, CSVs, or text files to shape generated outputs. It is less suitable if you need a full account-management suite, extensive collaboration controls, or more than two licensed devices.

Pros and cons

Pros

• Offline core scoring and preparation keep essential work available without a live connection.
• The 0–100% score combines usage, support, and sentiment into a clear review-prioritization signal.
• Document Vault adds PDF, CSV, and TXT context to QBR, triage, and advisor outputs.
• Local browser storage and the stated no-tracking policy reduce routine data-collection concerns.
• A one-time Pro price avoids recurring subscription renewal.

Cons

• The free research allowance is limited to three uses.
• Pro research is quota-based, with daily Perplexity and monthly Brave limits.
• The Pro license covers only two devices simultaneously.
• The product focuses on analysis and preparation rather than a broad customer-success management suite.

Alternatives

AccountLens is the alternative for teams that prefer MIT-licensed, self-hosted software and are prepared to manage their own infrastructure.

Dimension Labs fits data-focused users who can work within a 1,000-record monthly Explore tier and single-source AI-agent Q&A.

Verdict

CSI Pro is a strong choice for lean customer-success teams that want offline renewal scoring, consistent QBR and escalation preparation, and local handling of account data. Pro is worth choosing when document context and AI-enhanced outputs justify the two-device license and research quotas. Look elsewhere if you need a broader customer-success system, larger-seat deployment, or heavier collaboration and automation capabilities.
