A sequence of experiments, in the open.
Rheticus is in early beta. Here is what is built, what the beta has to prove, and what comes after it. There are no dates, because we would only be guessing.
- Built
Built
Does a persistent, evidence-based loop hold together on one desk?
0.1
The loop
- A roadmap from a goal, mapped field by field
- Lessons taught in parts, checked last
- The five states and the evidence log
- Practice, demonstrations and reviews
Done when: A result is still on disk after a restart, and decides the next session.
0.2
The plan
- Today, with the next thing to do and why
- A week planned into the hours you have
- Reviews on expanding intervals
- Flashcards on a spaced schedule
Done when: The next day, the app knows what you did and what comes next.
0.3
Depth
- Placement tests, checkpoints and projects
- Questions marked by code where code can
- Misconceptions named, and marks disputed
- Every subject taught its own way
Done when: A whole module can be completed, checkpoint included.
0.4
Your model, your material
- Any provider key, router or local model
- Keys in the system credential store
- Your notes, PDFs, books and pages, cited by page
- Usage costs and spending caps
Done when: A model failure at any point leaves the record intact.
0.5
Open at the edges
- The MCP server for outside agents
- Connections to GitHub, calendars, Anki and Zotero
- Markdown export and local backups
- Your own skills and tools
Done when: An outside agent fetches a task and records an attempt.
- Now
Early beta
Do learners come back for a second week, and why?
0.6
The early beta
- Free, with everything unlocked
- Builds for Windows, macOS and Linux
- Feedback and opt-in reports from inside the app
- Fixes from what beta learners tell us
Done when: Beta learners return in their second week, and we know what brought them back.
- Next
Stabilise
Can strangers install it without help from us?
0.7
Signed and updating
- A notarised macOS build
- Updates through package repositories and the Microsoft Store
- Installs tested on clean machines
Done when: Strangers install it on all three platforms without instructions.
- Later
Launch
Will people pay once for the whole thing?
1.0
General release
- The free version, with one track
- The full version, one payment
- The price, published first
- A restore drill passed
Done when: The download button on this site points at a signed build anyone can buy.
After that.
In the order we believe today. Each waits on evidence, not on a calendar.
The Kircher skills as open source
Needs: Skills that hold up across agents, with stable formats and docs
Encrypted sync and backup
Needs: Proven single-device retention
Curated learning packs
Needs: Knowing which outcomes keep people
Cross-domain connections
Needs: Reliable mastery data in two disciplines
Mobile review companion
Needs: Sync
Team and cohort licences
Needs: Individual retention
Not building.
Reasonable ideas, each postponed for a stated reason.
A full note-taking app
Good ones exist. The vault is plain Markdown any editor opens, and the app links it to lessons.
Badges and leaderboards
They reward showing up, not learning. Today shows study days plainly, with no rewards and no warnings.
Autonomous research agents
Unpredictable cost and quality, and nothing to do with the loop.
A hosted model in the price
We would become a token reseller. You keep the choice and the bill.
Voice tutors and study rooms
A second interface before the first is proven.
Certificates
We can show you your evidence. We cannot vouch for it to anyone else.
Help decide what gets built.
The early beta is free, with everything unlocked. What beta learners tell us decides what gets built next.
