# Echo

> Echo (echoappx.com) is an AI copilot for X (formerly Twitter). It learns how you
> write from your own posts, then helps you draft, rewrite, design, schedule and
> publish threads and posts without sounding like generic AI.

Echo is a web app — nothing to install. You sign in with your X account, Echo analyses
your recent posts to build an "Echo profile" that captures your tone, vocabulary and
recurring patterns, and every AI action afterwards is constrained by that profile.

The site exists in English and Spanish, and the language is part of the URL: English at
the root (`/`, `/pricing`, `/compare/…`) and Spanish under `/es` (`/es`, `/es/pricing`,
`/es/comparativa/…`). Every page carries reciprocal `hreflang` annotations and its own
canonical, so the two versions are separate documents, not one document that changes
depending on who is asking. English is `x-default`.

This file is the authoritative, single-language summary of the product for agents that
would rather read one page than crawl ten.

## What Echo does

- **Voice profiles ("Echo profiles")** — paste your X handle and Echo reads your latest
  posts to build a profile of your tone, vocabulary and structure. No long forms.
- **Profile training** — tell Echo which words to avoid, which phrases you prefer and
  what structure defines you. Each instruction is stored on the profile and applied
  automatically to every later rewrite.
- **Rewriting** — improve a hook, simplify a paragraph, translate a thread, or revise a
  whole draft. Every action respects the rules of the active profile.
- **Virality score** — analyses a draft and scores it against your recent posts before
  you publish.
- **Direct publishing to X** — connect the account once and publish full threads with
  one click. No copy-paste, no tab switching.
- **Scheduling** — visual daily/weekly calendar for scheduled posts and Auto-RTs.
  Recurring schedules and bulk publishing (CSV/JSON) on the Pro plan.
- **Image editor** — design covers and post images inside Echo: shapes, text, layers,
  guides, templates, AI background removal and AI image generation. Send the result
  straight to the thread editor.
- **Library** — saved threads, drafts and AI results, plus your published posts from X.

## Plans and pricing

All prices are in euros and include VAT. Billing runs through Stripe; you can cancel at
any time from Settings → Subscription. Paid plans can be billed monthly or annually.

| Plan | Monthly | Annual | Monthly credits | Echo profiles | Publishes to X |

  storage, PNG export with a watermark. No card required.

## How credits work

Credits are the unit consumed by every action that costs money. Indicative costs:
publishing a tweet is 10 credits, generating an image is 50, a Pro image is 140, and a
full profile analysis is 500. The exact cost is shown on the button before each action.

Credits reset at the start of each monthly cycle and do not roll over. There are no
top-up packs: if you run out early you either move up a plan (applied immediately, with
Stripe proration) or wait for the reset.

As a rough guide, Creator's 4,500 credits are about 450 tweets, 90 images or 9 profile
analyses per month; Pro's 13,000 are about 1,300 tweets, 260 images or 26 analyses.

## Frequently asked questions

**Do unspent credits roll over?** No. They reset at the start of each monthly cycle.

**Can I switch plans whenever I want?** Yes. The Stripe Customer Portal handles upgrades,
downgrades and cancellations. Upgrades are instant; downgrades apply at the end of the
current cycle.

**What happens to my Echo profiles if I downgrade?** You keep every saved profile, but
only the first N are usable under the new plan cap (Free: 1, Creator: 3, Pro: 10). The
rest become read-only until you upgrade again or delete them.

**Are taxes included?** Yes. The listed prices are final and include VAT; Stripe adds it
to your invoice automatically.

**Why can't the Free plan publish to X?** Each post has a real cost through the X API
(roughly €0.01 per tweet). Free is designed to carry no variable cost, so it works as a
local organiser and editor while you try the tool.

**How does the daily soft cap work?** Creator allows 30 posts/day and Pro 50 posts/day as
an anti-abuse measure. The cap counts individual tweets, so a 15-tweet thread counts as
15. Contact support if you legitimately need more volume.

Spanish: the same pages at `/es`, `/es/pricing`, `/es/comparativa` and
`/es/comparativa/<slug>`.

Each comparison page states plainly where the competing tool is better than Echo.
Competitor details were read from the vendors' own sites and are dated on the page;
prices change, so each page links to the vendor's live pricing rather than freezing a
number.

- Sitemap: `https://echoappx.com/sitemap.xml`. Robots: `https://echoappx.com/robots.txt`.
- Structured data (`SoftwareApplication`, `Organization`, `WebSite`, `FAQPage`) is
  embedded as JSON-LD in the landing page.
- Everything under `/dashboard`, `/studio`, `/scheduler`, `/image-editor`,
  `/echo-profiles`, `/inbox`, `/settings`, `/admin`, `/onboarding`, `/help` and `/api`
  is private and disallowed for crawling.
