See why your students misspell,
not just what.
Orthos auto-classifies every misspelling — vowel patterns, consonant blends, syllable omissions, orthographic doublings — so tomorrow’s lesson is a 30-second decision instead of a Sunday afternoon of color-coding.
Built by a special-education teacher running four intervention blocks a day. No district sales call, no procurement form.
From probe to plan in three steps.
-
1
Give a probe
Paste your word list or pick from your library. Orthos auto-categorizes each word by phonological pattern before you administer it.
-
2
Type student responses
Top-to-bottom entry, one student at a time. Each misspelling gets classified by subtype as you save — no more highlighting a spreadsheet on Sunday night.

See what to teach
The heat map flags words 50%+ of the class missed. Per-student profiles show where each kid’s errors cluster. Plan tomorrow in a glance.
Class-wide patterns at a glance
A weekly probe lands as one chart. Spot the words five of six students missed. Spot the suffix doublings. Spot the syllable drops. Plan tomorrow’s instruction in 30 seconds.
Per-student error breakdown
Every student gets a profile with their accuracy, their error categories, and their word-by-word history. Print it for the parent conference. Share it with the IEP team.
