A Telegram group is a many-to-many chat: every member can post, reply, and see the full message history, unlike a channel where only administrators publish and subscribers only receive. Groups top out at 200 members before Telegram requires converting them to a supergroup, which unlocks admin roles, pinned messages, and — if forum mode is enabled — topic-based sub-threads. Autogram automates channels, not groups: the broadcast, one-to-many model is what a scheduled or AI-generated post publishes into, and a group's open, conversational structure has no equivalent publishing queue to target.
The API distinguishes them as different chat types (group, supergroup, channel), and the difference is behavioral, not just a UI skin: any member of a group can send a message that every other member sees, while a channel post can only come from an administrator (human or bot) and channel subscribers cannot reply in the channel itself. A community discussion belongs in a group; a publishing feed belongs in a channel.
A regular group is capped at 200 members; past that, Telegram converts it to a supergroup, which supports up to tens of thousands of members, admin permission levels, message pinning, and slow mode. A supergroup can also enable forum mode, splitting the chat into named topics — a structure closer to a discussion board than a single stream.
Autogram's scheduling, AI content generation, and analytics are all built around the channel's one-directional publishing model: one administrator-controlled feed, an unlimited passive audience, and per-post view counts. A group has no equivalent 'queue' an automation tool publishes into — every member can already post directly — so the product surface Autogram automates is the channel, not the group.
