Telegram bots, websites and apps.

Occasional AI use does not justify another monthly plan: users need one place for text, documents, images and video, billed by request.

One chat covers answers, search, finished documents and video transcription without another monthly subscription. Uploaded files are scanned for malware, and conversation context is encrypted.

• YooKassa, international cards, cryptocurrency and Telegram Stars
• 50+ specialist modes, from marketing to psychology
• Conversation memory, RAG search and reminders in one chat
• Each task uses a model with the right level of capability so requests are not needlessly expensive
• An interrupted request can resume after a failure

UTM tags, QR codes, media compression, analytics checks and YML feeds are usually spread across separate services.

The tools run in the browser, so photos and video stay on the device. Pages remain indexable, and analytics waits for consent.

• 40+ tools covering UTM tags, QR codes, media compression, YML and A/B tests
• Photos and video never leave the device
• Each tool page is structured for search and sharing
• Yandex Metrika starts only after cookie consent

A scanner finding needs verification, a root cause and another check after the fix.

Detects the project stack, gathers evidence for each finding and separates confirmed defects from hypotheses.

• Source, dependency and change reviews
• Confidence levels and priorities for findings
• Validation of root-cause fixes

Teams managing several Telegram channels need one publication calendar and a shared place for media instead of sending every post by hand.

A team can prepare and schedule posts for several Telegram channels in one interface. Media stays available to the team, and updates are validated before release.

• One publication calendar for several Telegram channels
• Media is uploaded once and remains available to the team
• Scheduled posts publish without an open browser
• Updates are validated before production

publishing: scheduled · workspace: one calendar

Marketplace prices change, and a temporary site failure should not leave a gap in the tracking history.

Users can see how a price changed and get a signal when an offer becomes attractive. If a marketplace is temporarily unavailable, the check runs again.

• A 90-day price history with product thumbnails and smoothed charts
• A "time to buy" signal on each tracked item
• One tracked item brings together prices from Ozon, Wildberries and Ozon Travel
• A check runs again after a temporary marketplace failure

Bookkeepers copy invoice details into the banking app by hand; the work takes time and introduces typing errors.

A bookkeeper sends an invoice in a familiar format and receives a banking QR code without retyping payment details. Scans and photos are recognised, and low-confidence fields are extracted again.

• Five input formats: PDF, JPG/PNG, Excel, Word and RTF
• Pay per processed invoice instead of a subscription
• Works with exported invoices, scans and camera photos
• Low-confidence fields are extracted again before the QR code is returned

formats: 5 · output: QR ST00012

In a long Telegram chat, important points are mixed with hundreds of messages, voice notes and images that a text-only summary misses.

The bot turns text, voice notes and images from a selected period into one readable summary. If the primary AI service is unavailable, the request switches to a backup.

• Free and paid access with limits per chat and per user
• Five summary styles across text, voice notes and images
• Automatic switch to a backup AI provider after a failure
• Text in images is read before the summary is prepared
• Long summaries keep valid Telegram formatting

The partners' answers need to be compared without revealing where they disagree.

Partners answer separately; the result shows compatibility patterns without exposing individual disagreements, then produces a joint analysis for the couple.

• Each partner takes the test separately, and only matching answers are shown
• Statistical comparisons appear only when the sample is large enough
• The couple receives a consistent, shareable result card
• Simultaneous payments are applied once
• Each promo code can be redeemed only once

Exact-string matching rejects answers that are correct in meaning but phrased differently.

Correct answers are judged by meaning instead of exact wording. Older scores gradually carry less weight so new players can compete.

• Accepts correct answers even when phrased differently
• Older scores gradually lose weight, keeping the leaderboard open to new players
• A web admin panel manages the song catalogue and accepted answers

An anonymous service should not retain message text longer than delivery requires: every durable copy increases the impact of a leak.

The same moderation covers every delivery mode. People can reply to each other without either side learning the other's identity.

• Only conversation metadata remains after ordinary delivery, not the message text
• Drafts and scheduled text are removed when no longer needed for delivery
• Replies can remain open or work once; both sides stay anonymous
• Moderation checks toxicity before delivery
• Telegram restricts standard forwarding and saving for protected messages

The same ad can return with rewritten copy, a resized image or a watermark, so exact matching misses the duplicate.

The service finds the same ad after its copy is rewritten or its image is resized or watermarked. The original remains recoverable if comparison is interrupted.

• Finds rewritten ads by meaning, not exact wording
• Finds resized and watermarked versions of the same image
• Searches the history and removes repeated copies of one publication
• Incoming messages remain recoverable until comparison completes

An existing page needs editing without moving it into a site builder that changes the original layout and leaks admin styles into the site.

An adaptation of @delmaredigital/payload-puck with a Russian interface and isolated admin styles. Editors change blocks and preview them in the website’s styles.

• Keeps the existing page code and layout intact
• Russian editor and admin interface
• Drafts, publishing and version history through Payload
• Live Preview renders with the website's own styles
• Admin styles do not leak into published pages

An applicant ID in a URL is copied into browser history, Referer headers and access logs. An exam-result lookup does not need those copies.

Applicants receive results without exposing identifiers in URLs, browser history or access logs. The admissions team gets an audit trail for every change and can export PDF reports.

• Applicant IDs stay out of URLs, browser history, Referer headers and web-server logs
• Staff export result reports as PDFs with Cyrillic-safe filenames
• One deletion request removes the applicant's related records
• The temporary setup account turns itself off after the first administrator is ready
• Shared rate limits and repeat-offender blocking protect the public lookup

Each morning, a homeroom teacher needs to record attendance, remind late students and prepare the absentee report.

Students, parents and teachers follow separate flows. The teacher receives a ready absentee list, while staff can change message text without updating the bot.

• Attendance check-in, reminders and the teacher report run automatically
• Separate flows for students, parents and teachers
• The teacher receives one absentee report
• Staff edit message text in the admin panel without updating the bot

Seventeen servers across five jurisdictions were monitored separately; basic uptime checks did not show database lock waits, worker memory or backup state.

One dashboard shows server, database and Cloudflare health, while Telegram alerts report outages, expiring capacity and certificate risks.

• 49 HTTP and 17 ICMP probes
• Analytics for 27 Cloudflare zones in Grafana
• Alerts for outages, disk space, certificates and databases
• Every server has automatic protection against memory exhaustion and system hangs
• Backups share an S3 repository with automatic retention
