AI-guided English practice

Build fluent habits, not random streaks.

Klio AI turns daily English study into a guided loop of speaking, writing, vocabulary, and review. Less clutter. More usable progress.

  • AI conversation and sentence practice
  • Daily reading and writing prompts
  • Progress, streak, and quota-aware backend
01 Mobile-first

Built around a private mobile rollout, not a generic dashboard.

02 AI where it matters

Conversation, feedback, generation, and review backed by quota control.

03 Production backbone

HTTPS, isolated cache layers, PostgreSQL backups, and runtime health checks.

What Klio focuses on

Structured repetition with enough intelligence to stay useful.

Speaking practice

Prompted sessions and AI-supported speaking flows designed to push you past passive recognition.

Vocabulary retention

Save words, attach sentences, revisit difficult items, and keep the review cycle anchored to your own learning history.

Writing feedback

Generate level-aware prompts, write against a target, and get immediate structured evaluation.

Daily momentum

Reading, writing, and review are framed as a repeatable daily loop instead of disconnected screens.

Workflow

One system, four clear moves.

1

Capture

Add words, save examples, and create context while motivation is high.

2

Generate

Use AI to create sentences, prompts, and guided practice at the right level.

3

Evaluate

Check translations, review writing, and tighten weak spots before they fossilize.

4

Repeat

Return through a daily loop with stored history and measurable continuity.

Infrastructure

Shipping discipline behind the product.

Secure delivery

Cloudflare DNS, Caddy TLS, and a dedicated API host on `api.klioai.app`.

Protected runtime

Internal-only backend port, split Redis roles, JWT auth, and production headers.

Recoverability

Scheduled PostgreSQL backups plus restore smoke validation, not snapshot hope.

Current status

Klio AI is live on production infrastructure.

The mobile experience is the primary product surface. The public web layer exists to present the product and expose a stable production entrypoint.
