How ratings work
Scores are computed by published rules, then gradually adjusted by member ratings. They help you compare resources; they are not an official endorsement and we do not vouch for the content.
Current algorithm v1
System score
System score = 1 + 9 × Σ(weight × dimension value), out of 10. Missing inputs count as a neutral 0.5 and are marked on the listing page.
Tiers
- Audience
- < 100 → 0.1 · 100–999 → 0.3 · 1,000–9,999 → 0.5 · 10,000–99,999 → 0.7 · 100,000–999,999 → 0.85 · ≥ 1,000,000 → 1.0
- Channel activity (last post)
- ≤ 7 days → 1 · ≤ 30 days → 0.7 · ≤ 90 days → 0.4 · older → 0.1
- Group activity (online ÷ members)
- ≥ 5% → 1 · ≥ 1% → 0.7 · ≥ 0.2% → 0.4 · lower → 0.1
Risk caps
The higher the risk, the lower the ceiling, and caps apply to the final score too: 8–9 → ≤ 3.0 · 6–7 → ≤ 5.0 · 4–5 → ≤ 7.0. At risk 10 the score is fixed at 1.0 and member ratings cannot change it.
Member ratings
Signed-in members can rate a listing from 0.5 to 10 in steps of 0.5; one rating per account per listing, editable or withdrawable.
Final score = system score × (1 − w) + member average × w, where w = 0.4 × n ÷ (n + 5): 1 raters 7% · 5 raters 20% · 20 raters 32% · never above 40%. With no member ratings, the final score equals the system score.
What is never used
Ads and sponsorship, favorites, likes and editorial picks never enter the score.
Official backlink check
Some Telegram links on tool listings are inferred from a channel's description, and anyone can link a channel to a website. We only call a channel official, and only count the backlink dimension, when the tool's own website links back to that t.me address. If the site can't be fetched or doesn't link back, the dimension is 0 with no further penalty.
Where the inputs come from
Reviewer results come from the AI review against our Telegram listing policy; audience, verification and post times come from periodic snapshots of Telegram's public pages, not live data, with the collection date shown on each listing.
