CleanSpeak

Overview

CleanSpeak is a configurable moderation toolkit for services handling user-generated content. It is best suited to app, gaming, retail, hospitality, and enterprise teams that need custom policies and a choice of deployment. Its strongest case is broad filtering with workflow controls; the notable gap is that it can moderate audio but cannot filter it.

Key features

Custom blocklists catch negative words and phrases, including altered forms used to evade filters, and customers can amend or extend 22+ base language lists. Tunable machine-learning models and integrations with Google Perspective and SightEngine support analysis of text, images, and video. That mix suits services with distinct policies or multilingual audiences, but requires teams to shape the rules and models around their own standards.

Moderation queues support human review, escalation, and automated workflows. Rules can apply different actions to different content sources, while user scoring can trigger automated actions on accounts. These controls make CleanSpeak a stronger fit for teams managing ongoing community behavior than for buyers seeking only a standalone image classifier.

Reports cover moderator activity, content searches, and term or model frequencies, useful for tracking review work and recurring signals. Synchronous REST APIs return JSON, supporting integration into real-time applications for filtering, moderation, and user management. CleanSpeak says a single server can filter 10,000 or more messages per second, a meaningful option for high-volume deployments.

Customers can use the managed cloud service or install and maintain server software themselves. The privacy policy gives customers control over data sent through APIs or interfaces and lets them delete stored information through those interfaces. On-premise installation may help with COPPA and EU privacy requirements, but compliance remains the customer's responsibility.

Pricing

CleanSpeak uses custom pricing, with cloud and self-hosted options and discounts for startups and nonprofits. Contact sales for a quote. There is no free plan, but a 30-day free trial is offered without a credit card. Because support is a separate purchase, confirm whether the quote includes it: technical support is provided during the company's regular Colorado business hours only to customers who buy support services.

Platforms

CleanSpeak is available through the web and APIs, and server installation is described for Linux, macOS, and Windows. Self-hosting offers control over installation and maintenance; the managed cloud option avoids operating the server yourself.

Who it's for

CleanSpeak is a strong match for teams that need configurable text, image, and video filtering, human review queues, user scoring, and real-time integration in one toolset. Its deployment choice can matter to organizations with specific infrastructure or privacy needs. It is a poor fit when audio filtering is essential, or when a published price and included support are prerequisites for purchase.

Pros and cons

Pro: Custom blocklists, language lists, and source-specific rules let teams adapt moderation to their policies.

Pro: Review queues, escalation, automation, user scoring, and reporting cover both content handling and moderation operations.

Pro: Hosted and self-managed deployment, plus synchronous REST APIs, give teams options for integration and operations.

Con: Audio can be moderated but not filtered, leaving a gap for services that need voice-content filtering.

Con: Custom pricing and separately purchased support make costs and service terms important to settle before committing.

Alternatives

For image-focused moderation, WebPurify offers per-image AI moderation with real-time results and API access, as well as live moderation. Tisane API is worth considering if a free community tier matters: it includes 50,000 requests per month, though its rate is limited to 10 hits per minute and customization and technical support are excluded. PicPurify offers a free tier with 2,000 units and a $19 a month Starter plan for 10,000 units, for buyers who prefer published usage tiers.

Sightengine has a free tier and a $29 a month Starter plan with 10,000 operations, but its free plan excludes video processing and live-stream support. Google Cloud Vision API is an option for buyers who prefer pay-as-you-go image-feature billing and a free allowance. Hive Moderation provides selected models on a pay-as-you-go basis and free credits after adding a payment method, rather than CleanSpeak's custom-solution approach. Moderation API may suit smaller teams wanting a published monthly tier: its $79 a month Basic plan includes 10,000 messages, video and audio moderation, and three team members. Amazon Rekognition Content Moderation is another alternative.

Verdict

Choose CleanSpeak if your team needs customizable moderation across text, images, and video, with review workflows, user scoring, and a choice between hosted and self-managed deployment. Its flexibility and real-time APIs are the main reasons to shortlist it. Look elsewhere if filtering audio is central, or if you need a clear public price and support terms before speaking with sales.
