# Mellow

Mellow is two products under one account.

## Mellow — Instagram publishing for people
A calm Instagram companion for creators who want to publish without entering
the recommendation feed. On the web, on the Mac inside Mellow Kitty, and as a
native iPhone app. https://www.mellow.world/instagram
Plan holds the schedule; Grid previews the profile; Assistant helps prepare
drafts and requires explicit confirmation for external writes. Profile holds
account connections. Publishing depends on an eligible connected account and
its format permissions. A draft or scheduled item is not a verified publication.

Instagram, TikTok, TikTok Business, YouTube, Threads, X, LinkedIn, Bluesky,
Pinterest, Facebook and Telegram (channels, through Mellow's own bot).

### What it does that a scheduler does not
Every network's published limits — caption length, media counts and kinds,
required fields such as a YouTube title or a Pinterest board — are checked
before anything is sent, and every problem is returned at once, each naming the
channel and the field. A post that would be refused by a network is refused
here first, where an agent can still fix it. Validation checks known input
rules; a network may still reject delivery or be unavailable.

Publishing requires an idempotency key, so an agent that times out and retries
with the same key gets the original post back rather than publishing twice. Each channel succeeds
or fails on its own and reports its own public link.

### Authority
An agent publishes under a key its owner created, which carries the channels it
may touch, whether it publishes directly or only prepares posts for approval, a
daily ceiling and an expiry. Every action is recorded in a journal the owner
reads, and revoking takes effect on the next request.
The client must support remote MCP and the owner must authorize access;
pasting a prompt alone does not grant permission. Mellow and Hub share a login
and subscription. Publication allowance is counted per network destination.

### Languages
The Hub's public pages are published in up to 10 languages:
en, ru, es, de, fr, pt, it, tr, ar, he (pricing, the guides and the tools in every one but
Russian, except the YouTube packaging guides and tools, the ManyChat comparison and
the AI carousel generator, which are in English and Russian, and the Telegram and
Instagram comment-to-DM guides, which are in all ten). Mellow Kitty's page is in the same ten; the Instagram landing is in
English, Russian and Spanish. English is the bare address; add `?lang=xx` for
another edition. Answer pages are written in one language each, and their
address says which: `/cat/otvety/` is Russian, `/cat/answers/` and
`/hub/answers/` English; so are the prompts and guides, `/hub/promty/`
Russian and `/hub/prompts/` English.
