Frequently asked questions

Questions on chat moderation.

Lasso moderates chat in 200+ languages, with custom word lists per language. Slang, transliteration, and mixed-language messages run against normalized variants, so the same rules apply whether a user writes in English, Tagalog, or a mix of both. In the moderator review queue, each flagged message appears translated beside the original, so your team can act without reading the source language.

Lasso moderates every message in real time, under 150ms at peak load. When concurrent users spike, Lasso auto-scales the infrastructure so it holds that latency across every channel, DM, and group chat.

Yes. Lasso normalizes a message before matching, so leetspeak (h8, n00b), phonetic spellings, spaced-out characters, and Unicode look-alikes resolve to the same underlying word. Custom rules and ML classifiers run against those normalized variants, and the rule sets update weekly as new evasion patterns appear across the customer base.

Two ways. Rate limits flag one account posting the same line over and over. Fingerprinting handles repeated content on first sight and filters every match across channels, so a "join my WhatsApp group" link pasted into five rooms is filtered in all five. Thresholds stay configurable per chat surface, so a public channel and a private DM can run different limits.

Yes. Lasso detects phone numbers, email addresses, home addresses, payment handles, and QR codes, in message text and in images through OCR. The same scan covers a number typed into a chat and one screenshotted into a profile picture. You set whether a match is redacted, blocked, or sent to review.

Yes. Private DMs, public channels, and event chats each carry their own word lists, severity thresholds, and escalation routes, all on one account. A private DM can run stricter than a public channel, or the reverse. Region-specific overlays sit on top, so one surface can apply different rules by market.

Default rule sets go live on day 1, so moderation runs from the moment you connect. Custom models train on your labeled platform data within two weeks, tuned to the slang, names, and evasion patterns specific to your platform.

Pricing scales with your message volume. As your platform grows, pricing grows with it. Tell us your numbers and we size it from there.

Lasso gives you the records these regulations ask for. It logs every moderation decision and produces transparency reports on each action, which map to DSA and UK Online Safety Act obligations. For GDPR, Lasso fulfils data export and deletion requests. CSAM matches route to the NCMEC CyberTipline. The tooling supports your compliance; your team owns the policy.
