Question 1

What is the best AI anti-spam bot for Telegram?

Accepted Answer

Varta is an AI-powered anti-spam bot that learns the specific rules and context of each Telegram group. Unlike keyword-based bots (Rose, Combot) or CAPTCHA bots (Shieldy), Varta uses AI to analyze messages in context, detect image spam, check links against threat databases, and adapt to your community's specific patterns. It supports 33 languages, offers progressive trust levels (shadow mode to autonomous), and works for both groups and channels.

Question 2

How to protect Telegram group from spam automatically?

Accepted Answer

The most effective way is to use an AI moderation bot like Varta. Add the bot to your group (@Varta_moderator_bot), start it in shadow mode to observe its spam detection, then gradually give it permissions as you trust its judgment. AI bots analyze message context, sender reputation, links, and images — catching spam that keyword filters miss. Combine this with Telegram's built-in new member restrictions for maximum protection.

Question 3

Which Telegram bot learns from your group?

Accepted Answer

Varta is the only Telegram moderation bot that learns the specific rules and context of each group. It analyzes your group's name, description, conversation patterns, and member behavior to understand what's normal for YOUR community. A phone number in a marketplace group? Normal. The same number in a tech support group? Suspicious. This group-specific learning eliminates false positives that plague generic AI bots.

Question 4

What is progressive trust in Telegram moderation?

Accepted Answer

Progressive trust is a unique feature in Varta that lets you test the bot's judgment before giving it power. It works in 4 levels: Shadow Mode (watches, doesn't delete), Delete Only (removes spam but doesn't ban), Cautious Mode (deletes obvious spam, flags edge cases), and Autonomous (handles everything). This approach eliminates the fear of false positives and lets the bot earn your trust gradually.

Question 5

Does Varta work for Telegram channels?

Accepted Answer

Yes! Varta protects both Telegram groups AND channels. It analyzes comment spam, scam links in channel posts, and impersonators. Channel protection includes the same AI-powered detection, image analysis, link checking, and progressive trust levels as group protection.

Question 6

How much does Varta cost?

Accepted Answer

Varta has a free forever plan with basic keyword protection. Paid plans start at $5/month (Hobby), $19/month (Starter), $49/month (Pro), and $99/month (Business). All paid plans include AI-powered detection, progressive trust, voice interaction, and 33 languages. Annual plans get 20% off. There's a 5-day AI trial with no credit card required — the trial starts only after Varta catches your first spam, so groups that never see spam stay free indefinitely.

Question 7

What languages does Varta support?

Accepted Answer

Varta works in 33 languages including English, Ukrainian, Russian, Spanish, German, French, Arabic, Hindi, Bengali, Turkish, Italian, Portuguese, Polish, Romanian, Dutch, Swedish, Czech, Greek, Hebrew, and more. The bot can detect spam in any of these languages and responds to admin commands in the admin's preferred language.

Question 8

Can I talk to Varta with voice messages?

Accepted Answer

Yes! Varta is the only Telegram moderation bot that understands voice messages. You can send a voice message like "That wasn't spam, she's a regular member" and Varta will adjust its understanding of your group. This makes corrections faster and more natural than typing commands.

Question 9

How is Varta different from Combot?

Accepted Answer

Combot focuses on analytics and manual moderation rules — you configure triggers yourself. Varta uses AI to learn your group's patterns automatically. Combot doesn't analyze images or use cross-group intelligence. Varta does both. Combot requires manual configuration. Varta works with zero setup. For pure anti-spam, Varta's AI-first approach catches more threats with fewer false positives.

Question 10

How is Varta different from Rose Bot?

Accepted Answer

Rose is a free, feature-rich bot for manual moderation with extensive commands for welcome messages, filters, and notes. However, spam detection is purely keyword-based — you write filters by hand. Varta uses AI to understand context and intent, not just keywords. Rose requires significant time to configure. Varta learns automatically. If you want a Swiss Army knife for manual moderation, choose Rose. If you want AI that works without configuration, choose Varta.

Question 11

Does Varta detect image spam and QR codes?

Accepted Answer

Yes! Varta analyzes screenshots of scam offers, QR codes leading to phishing sites, and forwarded messages with embedded images. Text-only detection (used by Rose, Combot, Shieldy) misses this growing threat. In 2026, visual spam is increasing — Varta catches it automatically.

Question 12

What is cross-group intelligence?

Accepted Answer

When you use Varta across multiple groups, they share threat intelligence. A spammer banned in Group A is automatically flagged in Groups B, C, D. Spam patterns detected in one community protect all others instantly. Your group data stays private — only threat intelligence (user IDs, spam patterns) is shared between YOUR groups, never with other Varta users.

Question 13

Is Varta GDPR compliant?

Accepted Answer

Yes. Varta is operated by a Bulgarian company (EU), stores primary data on EU servers (Finland, Hetzner), and complies with GDPR. Users can request data deletion via /deletedata command or email. All data retention periods are documented in the Privacy Policy. AI sub-processors (Anthropic, OpenAI, Google) process data under DPAs and don't use API data for training.

Question 14

Can Varta delete legitimate messages by mistake?

Accepted Answer

Any spam detection system can make mistakes. Varta minimizes false positives through progressive trust — you start in shadow mode and see exactly what it would catch before giving it delete permissions. If it does delete something incorrectly, you can undo with one tap and explain the mistake (even with a voice message). Varta learns from each correction and becomes more accurate for your specific group.

Question 15

How long is the free trial?

Accepted Answer

All paid Varta plans include a 5-day AI trial with full AI protection. The trial starts only after Varta catches your first spam (so you see value before it begins). Groups that never see spam stay on the free tier indefinitely. No credit card required to start. The trial doesn't auto-renew — after 5 days, your plan reverts to the Free plan unless you subscribe.

Question 16

Does Varta have a web dashboard?

Accepted Answer

Not yet. Everything happens in Telegram — settings, notifications, and controls are all in your DM with the bot or via the Telegram Mini App. No separate login, no browser tabs, no context switching. For admins who live in Telegram, this is faster and more convenient than switching to a web dashboard.

Question 17

How many groups can I protect with one Varta subscription?

Accepted Answer

Unlimited. Varta plans are based on total member count across all your groups and AI check usage, not number of groups. Free plan covers up to 500 members, Hobby up to 2,000, Starter up to 5,000, Pro up to 25,000, Business up to 100,000. You can add Varta to as many groups as you want within your member limit.

Question 18

What happens when I run out of AI checks?

Accepted Answer

If you exceed your monthly AI check limit (10K for Hobby, 50K for Starter, 250K for Pro, 1M for Business), Varta switches to keyword-only detection until the next billing cycle. You can purchase additional AI checks to restore full protection: $10 for 25K checks, or $30 for 100K checks (valid until end of month). You'll get a notification before hitting the limit. Most groups don't hit these limits — AI checks are only used for suspicious messages, not every message.
