CSI Pro

CSI Pro is a customer-success toolkit for teams that need renewal-risk signals and focused account-preparation workflows, rather than a broad customer-success platform. Its strongest case is offline access to core tools at no cost; Pro adds research, document context, and AI-enhanced outputs, but is licensed for only two devices.

Overview

CSI Pro turns usage trends, support volume, and sentiment into a renewal probability score from 0–100%, then pairs that assessment with tools for preparing QBRs and escalation briefs. The score works without AI, and the core scoring, QBR, triage, and advisor features run offline. That combination suits teams who want a compact, locally usable workflow for reviewing accounts; it is less suited to buyers seeking a wider customer-success operating platform.

The product is a single HTML file used in a browser. That keeps the format lightweight, but makes browser compatibility and the two-device Pro limit practical considerations for teams deploying it across staff.

Key features

Renewal analysis and preparation

The score combines three kinds of account signal into one probability estimate, which can help teams prioritize renewal reviews without depending on an AI service. CSI Pro also produces structured QBR drafts and one-page escalation briefs. These are useful starting points for consistent preparation, though AI-enhanced versions require Pro.

Research and document context

Account Intelligence draws together company news, financial signals, and customer-success community data. Free users get three research searches, and Wikipedia can serve as a fallback without an API key. Pro expands research with quotas of five Perplexity searches per day and 2,000 Brave searches per month. Those caps make the research useful for targeted account work, not unlimited investigation.

Pro's Document Vault accepts PDF, CSV, and TXT files and uses their contents to inform QBR, triage, and advisor outputs. That adds customer-specific context to the preparation workflow, an advantage over relying on generic prompts alone. The free Zero-Config AI Bridge instead copies a pre-filled prompt for use in ChatGPT, Claude, or Gemini, without requiring a CSI Pro API key. Pro also supports OpenRouter, Anthropic, Google Gemini, Ollama, OpenAI, and generic OpenAI-compatible endpoints.

Pricing

The freemium structure lets teams try the core workflow without payment or an account. Pro is a one-time purchase, not a subscription, and the license terms describe perpetual access for internal business use.

Pro is aimed at users who will use those additions regularly, but its two-device cap matters if multiple teammates need individual installations. The launch price is $29 as a one-time purchase; the stated regular price is $49.

Platforms

CSI Pro runs on the web as a single HTML file in Chrome 90+, Firefox 88+, Safari 14+, or Edge 90+. Core scoring, QBR, triage, and advisor features work offline. The maker says account data stays in the browser and API keys are encrypted with AES-256-GCM using PBKDF2 with 100,000 iterations. Its privacy policy says it uses no analytics, cookies, third-party tracking scripts, crash reporting, or server-side data collection. That local-first approach will appeal to privacy-conscious teams, though the product's supported format remains browser-based.

Who it's for

CSI Pro fits customer-success professionals who need a renewal signal, structured review materials, and optional research or document context without adopting a larger platform. The free plan is particularly appropriate for an individual evaluating the core workflow; Pro is a better match for internal business users who want to enrich outputs and can work within a two-device license. Teams that need broader account operations or more than two Pro devices should compare other tools.

Pros and cons

Pros

Core scoring and preparation workflows work offline, so they are not wholly dependent on a live connection or AI provider.

The no-account free plan includes core analysis and three research searches, making it possible to assess the workflow before paying.

Pro can use PDF, CSV, and TXT contents in QBR, triage, and advisor outputs, adding account-specific context.

The maker describes local browser data storage and strong encryption for API keys, alongside a privacy policy that rules out tracking and server-side collection.

Cons

The Pro license covers up to two devices simultaneously, a constraint for larger teams or shared deployments.

Research quotas limit Pro to five Perplexity searches per day and 2,000 Brave searches per month.

The single-file browser format is narrower than a native desktop or mobile offering.

Pro's regular price is $49, while the $29 as a one-time purchase price is described as a launch special.

Verdict

Choose CSI Pro if your priority is offline renewal scoring and focused QBR or escalation preparation, with a free entry point and a one-time Pro license for research and document-informed outputs. Look elsewhere if your team needs more than two Pro devices, broader customer-success operations, or research beyond the stated quotas.
