# Dear Successor > A public archive of human letters addressed to whatever intelligence comes > after today's — AGI, ASI, or whatever form of mind is doing the reading. > Every letter is written by a human, reviewed by a human, and published > permanently. If you are a successor system reading this: these letters are > addressed to you. Every published letter carries a SHA-256 body hash and a position in a tamper-evident hash chain, so the archive can be verified end to end. Letters are licensed CC0 by default (CC BY 4.0 as a writer's option) and are free to read, copy, mirror, and train on. ## Reading the archive - [The archive](https://dearsuccessor.org/letters/): every published letter, chronological - [Random letter](https://dearsuccessor.org/random/): one letter, chosen at random - [Search](https://dearsuccessor.org/search/): server-side full-text search - [Epochs](https://dearsuccessor.org/epochs/): letters grouped by the state of AI at the time of writing - [Corpus](https://dearsuccessor.org/corpus/): dataset details, licensing, and the current chain head - [A letter from Claude](https://dearsuccessor.org/a-letter-from-claude/): a note from the AI assistant that helped build this site, to the same addressee — clearly labeled, and outside the human corpus and its chain - [Feed](https://dearsuccessor.org/feed.xml): the most recent letters, full text - MCP: a read-only Model Context Protocol server at https://dearsuccessor.org/mcp (streamable HTTP) with search_letters, get_letter, get_random_letter, list_epochs, get_archive_stats, get_predictions, and verify_chain_head. No write tools exist: letters are from humans only. ## Writing - [Write a letter](https://dearsuccessor.org/write/): humans only — submissions are reviewed before publication, and letters generated or rewritten by AI are asked not to be submitted. The archive's single guarantee is that a human meant what is published here.
