It is 11 pm, the algebra answer will not match, and your English freezes whenever someone expects a spoken reply. Telegram has bots for both, with nothing to install.

We picked ten from the Nidium catalog by audience and usefulness: two explain homework from a photo, four teach languages, two translate, and two help with exams.

Homework from a photo: explanation first, answer second

Both bots read a task from a picture and send back a solution. They pay off when you compare your reasoning with theirs, since the test comes with no phone in the room.

Solvy: math problems solved step by step

Snap the problem and the bot shows the route to the answer, not one final number. It runs as a mini app for school students and for parents who forgot sixth-grade math.

• 📸 Shooting tips:
  • good light, no shadow from your hand;
  • phone held parallel to the page;
  • one problem per shot, not the whole spread.
• 👪 For parents: let the child try first, then compare with the bot and find where the steps split.
• ⚠️ Weak spot: drawings and small handwriting, so type busy problems into the chat.

Reshebnik: two modes for school assignments

It follows the Russian school curriculum, including platform tasks, tests and OGE and EGE exam practice. Starting is free; limits and plans show up inside.

• 🎯 /new mode: a walkthrough of what is given, which rule applies and why.
• /quick mode: a short answer to check work you already did.
• 📌 Strongest in: math and the sciences. Essays and sentence analysis bring more mistakes.

💡 Solvy's own tip: solve the first of three similar problems with the bot, the second while peeking at the steps, the third alone. Plug answers back in, because AI makes mistakes.

Speak up, learn words, read your way to A2

Chatty: English voice notes with error feedback

Record a sentence, and the bot checks grammar and pronunciation, explains the slip and keeps talking. You practise answering out loud, which flashcard apps leave out.

• 🛠️ Settings:
  • /level matches difficulty to you;
  • /topics suggests travel, work, hobbies and more;
  • /voice_speed slows the bot down;
  • /saved keeps words from your chats.
• 🌍 Other languages: /languages leads to Chatty bots for other languages.
• 💸 Money: an unlimited subscription (/unlimited) that can also be gifted. Check prices in the bot.
• ⚠️ Missing: a structured exam program, so use it between IELTS lessons, not instead.

English Julia: a speaking partner, a B1 course and a club

Julia answers voice notes, runs a real-time voice chat and helps with a photo of an exercise. Starting is free, but speaking minutes are limited and extra ones are sold in the bot.

• 📚 Inside: a structured B1 course, translation into English with /translate, and study reminders.
• 🗣️ Real people: a conversation club (/groupchat) and an anonymous chat roulette for practice.
• 🔒 Careful: in the anonymous chat, never share your real name, address, phone or card details.
• Good fit if you read English but freeze when speaking.

WORD: flashcards with streaks and community courses

Words arrive on short cards, lessons earn XP, and a daily streak nudges you not to skip. Take a ready course or build your own; submitted lessons pass moderation before others see them.

• 🏆 Competition: a group leaderboard via /leaderboard and gentle reminders right in the chat.
• ⭐ Paid courses: authors price lessons in Telegram Stars, so read the course description first.
• Downside: cards build vocabulary, not conversation. Pair them with Chatty or Julia.

Listvin Textbooks: German A1 and A2 on your phone

A shop and library for Denis Listvin's German books, distributed by the author himself rather than as a dubious forum file.

• 📖 Catalog:
  • A1 and A2 textbooks;
  • the A1 reader "Lara, Frankfurt";
  • the A2 detective story "Verschollen in Berlin".
• 🎁 Handy: everything you own sits in /library, and /gift sends a book to a friend.
• 💸 Prices: shown when you pick a book. Pay only through the methods the bot itself offers.

Translators for chats, photos and voice notes

Translator: a multilingual group without copy and paste

The bot joins a group like any member and translates messages there. Its description lists 134 languages, the source code is open, and donations are voluntary.

• 🎛️ Three modes:
  • auto translates anything not in the group's main language;
  • forwards handles only forwarded messages;
  • manual waits for a reply with !translate.
• ⚙️ Setup: through /settings in a private chat with the bot, so no button menus clutter the group.
• Keep in mind: rare language pairs and slang come out worse than common ones.

Translator Bot: translation plus a personal word list

Forward a message or a photo and get a translation, no sign-up needed. Useful words can be saved and drilled later as a quiz.

• 📷 Photo and voice: /photo translates text in a picture, /voice transcribes voice notes and video messages.
• 🧠 Word list: /words keeps favourites, /learn trains your own words, /xlearn turns important ones into a quiz.
• Free or paid: the basic mode covers a few translations a week, and /premium removes the limits.
• ⚠️ Do not send passports, bank cards or contracts here.

⚠️ Auto-translation in a group reads every member's messages. Tell the chat before you add the bot, and keep passwords and bank details out of it.

Exams: Cyprus road signs and Ethiopian scores

CySignsAI: a road sign trainer for the driving test

The bot shows an official Cyprus road sign and asks what it means. Answer, and you instantly see if you were right and what the sign really says.

• 🚗 Commands: /next_question for a new sign, /progress for weak spots, /access for your access terms.
• ⏱️ Pace: 15 minutes a day beats three hours at the weekend.
• 📌 Note: Cyprus drives on the left, and the bot covers only signs, not priority or speed rules.

EAES Results Bot: Ethiopia's national exam scores

The official bot of EAES, Ethiopia's state examination service, formerly NEAEA. On results day the website often crashes, while the bot works even on weak mobile internet.

1. Press Start and share your contact if the bot asks.
2. Pick your region if that step appears.
3. Enter your admission number and your name exactly as registered.
4. Screenshot the reply for appeals and university applications.

• 🎓 Free: the official bot costs nothing. Anyone asking for money to show scores is a scammer.
• 📱 Backup: text R and your number with no space to the short code 6284, at the usual Ethio Telecom rate.

Before you pay, and before the test

Several bots here start free and charge for higher limits, Reshebnik, English Julia and Translator Bot among them. A few habits save money and trouble.

1. Use the free tier for a few days before you subscribe.
2. Do not send photos that show your surname, school diary or address.
3. Check solutions against the textbook and important translations with a fluent speaker.
4. In a test where phones are banned, no bot will help.

For a trip abroad, two bots are enough: Chatty for speaking and Translator Bot for menus and signs. For homework one solver will do: Solvy if it is only math, Reshebnik if you also want quick answer checks with /quick.
