CSI Pro

CSI Pro is a browser-based toolkit for customer success teams assessing renewal risk and preparing account reviews. It suits teams that want offline core workflows in a compact tool rather than a broad customer-success platform. Its free plan covers scoring and analysis; Pro is for teams that need document-informed work and AI-enhanced outputs.

Overview

CSI Pro converts usage trends, support volume, and sentiment into a renewal probability score from 0–100%. Account research and customer-success document preparation sit alongside that score, making it useful for teams that want to connect risk assessment with review preparation. Its focus is deliberately narrow: renewal analysis and supporting materials, not a full account-management suite.

The tool runs as a single HTML file in a browser, and core scoring, QBR, triage, and advisor features work offline without AI. That makes the basic workflow less dependent on connectivity, although expanded research and AI-provider features require an online connection.

Key features

Scoring and customer materials

The renewal score draws on three signals—usage trends, support volume, and sentiment—to give teams a single estimate for prioritizing account reviews. CSI Pro also generates structured QBR drafts and one-page escalation briefs. These provide a starting point for repeatable preparation; teams that want AI-enhanced outputs need Pro.

Account research and document context

Account Intelligence combines company news, financial signals, and customer-success community data. Free users get three research searches, and Wikipedia serves as a fallback without an API key. Pro adds research quotas of five Perplexity searches per day and 2,000 Brave searches per month, useful for teams that research accounts routinely but still bounded enough to matter at higher volumes.

Pro's Document Vault accepts PDF, CSV, and TXT files and uses their contents to inform QBR, triage, and advisor outputs. That can make prepared materials more account-specific, but the Vault is not part of the free workflow.

AI and privacy

The free Zero-Config AI Bridge copies a pre-filled prompt for use with ChatGPT, Claude, or Gemini without requiring an API key in CSI Pro. Pro also supports OpenRouter, Anthropic, Google Gemini, Ollama, OpenAI, and generic OpenAI-compatible endpoints. This range gives teams flexibility over provider choice; teams that prefer a fully offline workflow can stay with the core features instead.

The maker says account data stays in the browser and API keys are encrypted with AES-256-GCM and PBKDF2 at 100,000 iterations. Its privacy policy says it uses no analytics, cookies, third-party tracking scripts, crash reporting, or server-side data collection. These are meaningful privacy commitments, though teams should still assess the tool against their own data-handling requirements.

Pricing

Free is a sensible fit for occasional scoring and analysis: there is no account requirement, and core features work offline. The three research searches limit how far it goes for ongoing account intelligence. Pro Lifetime is aimed at teams that need the Vault, enhanced outputs, or more research; its perpetual license is for internal business use and covers up to two devices, so it is not a broad multi-seat team license. A free trial is offered, but no trial length is given.

Platforms

CSI Pro runs in a web browser. Its specifications list Chrome 90+, Firefox 88+, Safari 14+, and Edge 90+. The single-file format and offline core features suit users who want browser-based access without depending on a continuously connected service.

Who it's for

CSI Pro is best for customer-success professionals who need a renewal-risk signal plus QBR and escalation preparation, especially when offline access or local data handling matters. It is less suited to organizations seeking a broad platform for account operations, or teams that need more than two licensed devices under one Pro license.

Pros and cons

Pros

• Offline core workflows: Scoring, QBR, triage, and advisor features work without AI or an internet connection.
• Useful free starting point: Core scoring and analysis are available forever without an account.
• Document-informed Pro outputs: The Vault accepts PDF, CSV, and TXT files to inform several customer-success materials.
• Provider flexibility: Pro supports several named AI services as well as compatible endpoints.

Cons

• Free research is limited: Three searches may be insufficient for teams reviewing many accounts.
• Pro is limited by device count: The lifetime license allows simultaneous use on only two devices.
• Expanded features depend on connected services: Research quotas and external AI-provider workflows make online use relevant beyond the offline core.

Alternatives

Customer Success Analytics Software is the broader category to explore when comparing tools for this discipline.

• Bruin for Customer Success is worth considering if you want a free tier with $100 in credits and 50 AI tasks, or need its API, desktop, Linux, or self-hosted platform options.
• Muntri is an alternative if you want a practice-call product: its free plan includes three practice calls and a private workspace, while its paid Practice Arena costs $299 a month.
• AccountLens may suit users who prefer self-hosting; its free MIT-licensed option requires you to provide and manage infrastructure.
• Dimension Labs is an alternative for users who want an Explore tier capped at 1,000 records per month, with one data source and CSV export.
• GainTrace is an alternative with a free tier capped at 25 companies, 100 contacts, and 5,000 events per month.
• Hook is another paid alternative.
• Custify is worth considering if you want a paid platform with a free trial and custom pricing.
• Planhat is a paid alternative with custom-priced CRM and PSA plans.

Verdict

Choose CSI Pro if renewal scoring, offline core analysis, and customer-review materials are the work you need to streamline. The free plan makes those basics accessible, and Pro adds the strongest differentiators: document-informed outputs and account research. Look elsewhere if you need a broader customer-success platform or a license covering more than two devices.
