D&D Edition Converter
Drop in a creaky old module. THAC0, descending AC, ascending CR, the morale rules nobody used: the agent rejiggers all of it into 5e stat blocks. The first 3 sections are on the house.
How it works
Hand it your PDF
AD&D, 2nd Edition, 3e, 3.5e, 4e. Scanned tomes welcome; the OCR chews through every page.
The agent transcribes section by section
It identifies the parent edition, fetches the official 5e stat block when one exists, and rebuilds bespoke ones from DMG CR guidance otherwise. Every encounter, trap, and saving throw gets ported. Free preview covers the first 3 sections.
Download or unshackle the whole tome
Out comes clean markdown: 5e mechanics under the hood, the original prose untouched. Sign up and connect your OpenRouter key or ChatGPT account to finish the rest.
Frequently asked questions
What editions can it convert from?
AD&D 1st Edition, AD&D 2nd Edition, D&D 3rd Edition, D&D 3.5e, and D&D 4th Edition. Everything lands in D&D 5th Edition (2014 rules).
What exactly gets converted?
All the mechanical scaffolding: armor class, attack bonuses (THAC0 included), saving throws, hit dice, damage, spell references, treasure, trap DCs, encounter composition, and stat blocks. Boxed read-aloud text, maps, handouts, and flavor prose are left exactly as the author wrote them.
How accurate is the conversion?
When a creature exists in the 5e SRD, the agent points to the official stat block. For homebrew or edition-flavored monsters, it builds a bespoke one calibrated against DMG CR guidelines. Anything ambiguous gets a [CONVERTER NOTE] marker so you can sanity-check at the table.
Does it handle the full adventure or just encounters?
The whole module: chapters, rooms, appendices, encounters. The agent works through it section by section so nothing slips. Non-mechanical content passes through untouched. The free preview transcribes the first 3 sections (or the first 20 pages, whichever caps first); connecting your own model account unshackles the rest.
Is it free?
Yes. LorePanic is free and open source. The preview needs no account: one PDF per day, the first 3 sections transcribed (capped at 20 pages) so you can check the quality first.
To finish a tome, sign up and connect your own model account: an OpenRouter key or your ChatGPT Plus subscription. Your provider bills you for what the conversion uses, and LorePanic adds nothing on top.
Why do I need my own model account for a whole book?
Reading the source, hunting down 5e equivalents and rewriting every stat block is a lot of model work: a full module can cost a few dollars at provider rates. LorePanic runs on a small shared allowance that everyone splits, so one full conversion would eat everybody's day. On your own account, you pay only for your book.
Can I finish a partial conversion later?
Yes. Each converted section is stashed on disk. Start with the preview, sign up later, and the agent picks up at exactly the section that came next. No re-OCR, no re-converting work that is already done.
