Searching for “Telegram voice message bot” returns dozens of results. Most of them do the same thing: convert audio to text. But transcription and summarization are very different — one gives you everything that was said; the other gives you only what matters. This comparison covers both categories.
Test setup: we used the same 8-minute, 47-second voice note — a manager summarizing a team standup in English, including three action items, two names, a deadline, and a budget figure. We scored each bot on output quality, accuracy, speed, free tier, and UX.
What we measured
- Output type — full transcript, paragraph summary, or bullet points?
- Accuracy — did the key facts survive (names, deadline, budget)?
- Speed — how many seconds for the 8:47 test note?
- Free tier — how much without paying?
- UX — sign-up required? Works in groups?
1. TgVoiceBrief (@TgVoiceBriefBot)
Summarizer · Free + $5/mo · No sign-up
The only bot in this list built from the ground up as a summarizer rather than a transcriber. On our test note it returned 4 bullet points in 7 seconds, preserving every key fact — the deadline, budget, both names, and the action items — while removing all filler.
Output on the test note (8:47):
- • Deadline: Friday, November 7
- • Budget approved: $12,000
- • Sarah delivers design mockup by Wednesday; Tom reviews
- • Next standup: Tuesday 10am
⚡ 7 seconds
Pros
- ✓ Bullet points, not a wall of text
- ✓ Fast (6–8 s typical)
- ✓ Works in group chats
- ✓ No sign-up needed
- ✓ Long notes on paid plan
Cons
- ✗ Free: 10-min limit per note
- ✗ 20 summaries/day free
Free: 20/day, up to 10 min · Premium: $5/mo, unlimited
2. Whisper STT Bot
Transcription + basic summary · Free with limits
One of the most popular transcription bots, with 120+ language support and a basic summary mode. On our test it produced a full transcript first, then a 2-sentence summary that missed the budget figure and one of the names. The summary is a secondary feature, not the main focus.
Pros
- ✓ 120+ languages
- ✓ YouTube, Instagram too
- ✓ Good transcript accuracy
Cons
- ✗ Summary misses details
- ✗ Slow on longer notes
- ✗ Small free tier
Free: 5/day · Paid: ~$5/mo
3. ScreenApp
Multi-format SaaS · Free tier · 30+ languages
ScreenApp is primarily a SaaS product for transcribing meetings, videos, and audio. Telegram integration exists but it's not the native experience. On our test it produced a solid transcript with an AI notes section, but the Telegram bot UX requires extra steps compared to native bots.
Pros
- ✓ 30+ languages
- ✓ AI meeting notes
- ✓ Export to Docs/Notion
Cons
- ✗ Not Telegram-native
- ✗ Extra steps required
- ✗ No group chat support
Free: limited mins/mo · Paid: from ~$12/mo
4. TranscribeMe
Transcription only · 2M+ users · Paid
TranscribeMe is one of the oldest and most established transcription services, with 2M+ users. Telegram support is available. However, it does transcription only — no summarization mode exists. On our test it produced an accurate, well-formatted transcript. If you need the full text verbatim, this is reliable; if you need a summary, look elsewhere.
Pros
- ✓ High accuracy
- ✓ Clean formatting
- ✓ Established product
Cons
- ✗ No summarization
- ✗ Mostly paid
- ✗ No group chats
Free: very limited · Paid: from ~$8/mo
5. SaveDay
Save + search + summarize · Multi-format
SaveDay focuses on saving and searching voice notes, PDFs, and articles — with a summary layer on top. The Telegram integration lets you forward voice notes and get a summary plus a searchable archive. On our test the summary was concise (3 sentences) but lost the deadline and budget. The archive/search feature is genuinely useful if that's what you need.
Pros
- ✓ Searchable archive
- ✓ Multi-format (PDF, links)
- ✓ Shareable notes
Cons
- ✗ Summary loses details
- ✗ Not voice-first
- ✗ Limited free tier
Free: limited · Paid: from ~$9/mo
