Meet your mentor
Every Spark & Anvil app has a friendly mentor character that demonstrates, asks, and patiently scaffolds learning. On-device AI personalizes the mentor's responses to your kid's progress — never connecting to a server, never collecting data.

#dc2626 EditQuest flips the desk — YOU are the teacher. A confident-but-wrong writing robot hands in its work, and across 16 editing and proofreading missions you mark each sentence ✓ or ✗ and then write the fix: end punctuation, capitalization, commas and run-ons, apostrophes, subject–verb agreement, verb tense, homophones, pronoun clarity and plain concision. The Red-Pen Guild — ten friendly copy-desk editors who each hunt ONE class of error — teach you to SEE the mistake before you fix it, the skill that turns a reader into an editor. Ages 9–14, on-device, no accounts, no ads.
Characters who teach
Meet the cast
EditQuest's 10-member 'Red-Pen Guild' are friendly copy-desk editors, and each one's defining act IS one class of error it hunts and fixes (spot the guild-member's mistake and you have learned the rule): Cappy (capitalization) · Pip (end punctuation) · Splice (comma splices & run-ons) · Listy (commas in a series) · Apostro (apostrophes) · Echo (homophones) · Concord (subject–verb agreement) · Tempo (verb tense) · Ana (pronoun clarity) · Trim (concision). Their mentor Proofa is the editor-in-chief.
Cappy
Capitalization — makes proper nouns and every sentence's first word stand tall; its defining act is catching a lowercase name or opener
Read chapter →
Pip
End punctuation — gives each sentence its right ending (. ? !); catches a sentence that stops with the wrong mark or none
Read chapter →
Splice
Comma splices & run-ons — separates two full sentences a comma wrongly glued together, or breaks a run-on that never stops
Read chapter →
Listy
Commas in a series — sets the pauses between items in a list so the list reads cleanly
Read chapter →
Apostro
Apostrophes — sorts possessives from contractions from plain plurals (its vs it's, dogs vs dog's)
Read chapter →
Echo
Homophones / spelling-in-context — hears the words that sound alike and picks the right one (their / there / they're)
Read chapter →
Concord
Subject–verb agreement — matches a verb to its subject's number (one bird sings, two birds sing)
Read chapter →
Tempo
Verb-tense consistency — keeps a passage in one time; catches a sentence that slips from past to present
Read chapter →
Ana
Pronoun clarity — makes every pronoun point clearly to the one noun it stands for
Read chapter →
Trim
Concision — cuts wordiness and redundancy so the sentence says it once, clearly
