Astelio is a personal AI workspace that grows deliverables (artifacts), not just chat. Chat. MCPs. Artifacts. ■ The Astelio AI engine Our own engine reads your info, plans how to look things up and finishes using only the facts it gathered. 1. Read about you — loads your survey answers and Memory, always up to date; your request always comes first, and the newest instruction wins however long the conversation runs 2. Think through the goal and steps — decides the final goal and the steps first, and never uses places or topics your request doesn't mention 3. Research step by step — creates keywords for each step and searches with MCP for every one of them 4. Summarize each section — step results are summarized in order and kept as a Markdown data note so you can check the evidence later 5. Finish using only evidence — builds HTML and more from that data alone; numbers, URLs and phone numbers are checked against what was fetched Text is written on your iPhone. Conversations, Memory and files are never sent to an external AI service. ■ What you can do ・Weather: visual reports with forecasts, typhoon information, weather maps, satellite images and rain radar ・Trip plans: picks indoor or outdoor places for each day’s weather, looks up events, hotels and meals for your dates, and builds an HTML itinerary with maps, photos and sources — every place with its address and a Google Maps link ・News, events and outings: topic-by-topic digests, event lists built from web search and the details of the pages found, and spot ideas that fit the weather ・Documents: Word, PowerPoint, Excel, HTML and Markdown as real files. Slides pick card, chart, KPI, process, table and illustration layouts from the content ・Maps: routes are drawn in the app with Apple Maps, and open in Google Maps ・Research: reports, learning courses, YouTube scripts and slides built from the pages it reads on the web, with photos and sources ・Attachments: reads pictures, PDFs and Word / Excel / PowerPoint files on your device (text recognition), summarizes them and uses them as material for your request ・URL summaries and study notes using Microsoft Learn and Wikipedia ・MCP Hub: use the free built-in MCPs right away, or add and build your own by URL ・Skills: save procedures as SKILL.md files — just ask “create a skill that does …” ■ Gets smarter about you, gradually Answers to the optional first survey and your conversations are saved to Memory, which you can review, edit or delete at any time. Addresses stay on your device; external services only receive coordinates or the city name. ■ Plans (one-time purchase, no subscription) ・Free: 5 chats per day, 5 projects in total ・Astelio Unlimited (¥1,500): unlimited chats and projects Notes: The interface is available in English and Japanese. Generated deliverables and built-in skills currently work best in Japanese. Some features run on devices where Astelio AI is available; on other devices the app still works with MCPs and templates.

Verdict
The clearest difference is in-app purchases: MLC Chat at none against Astelio's 1. MLC Chat also leads on iOS requirement (17.0 vs 26.0). Astelio's advantage is update cadence (weekly vs every 2 months). On price, ads and device support there is nothing between them.
