The complete system for behavioral observation.

Keep your attention on the student while Sightline brings the whole workflow into one place, from recording to the write-up. Student records stay on your machine.

Everything runs on the computer in front of you.

You shouldn't need a DIY toolkit for observation.

A timer, a tally grid, a spreadsheet, a draft in Word. Juggling them by hand takes more of your attention than the student does.

Sightline’s session results for one partial-interval observation: per-behavior magnitude percentages, an occurrence chart broken out by activity, and the full interval raster with its activity timeline.

Sightline.
One tool, start to finish.

Record, time, total, and draft in one place, nothing retyped between them. Your results are ready before you’ve left the room.

  1. Writer’s Workbench

    Write up from the record,
    not from memory.

    Sightline keeps your coded record and analysis open beside the draft, so you assemble the write-up from the evidence in front of you.

    The Sightline write-up workspace: an editable FBA draft on the left with a contingency table of ABC instances inserted below the narrative, and its evidence on the right, showing the antecedent-behavior-consequence contingency and the ABC entries the draft draws from.
  2. It’s all there when you need it.

    An evaluation is rarely one observation. Every session, result, comparison, and draft for a student stays in one workspace.

    Sam Sample’s workspace lists four October 2025 sessions with dates, contexts, recording methods, and durations, alongside navigation to the Case File and FBA Workspace.
Observation methods

One workflow, eight methods.

Choose one and Sightline reshapes the clock, scoring, and results to match. The workflow around them stays the same.

iPhone companion

Record from your phone.

On-device AI

Less to draft. More time for students.

Most AI tools for this work send the student’s record to a company, and a draft comes back. Sightline’s model is built into the app, working only from the record you coded.

  • Observation summaries

    A professional, report-style summary of one session that leaves interpretations and implications to you.

  • FBA write-up support

    Get draft hypothesis statements and session narratives based on Sightline’s analysis of your coded ABC entries, ready to review and edit.

  • Dictation and voice notes

    Dictate into any Sightline text field, with optional AI cleanup to remove filler words and false starts and fix punctuation. Your computer also transcribes Companion voice notes into the session log.

Student privacy

What you don’t share, you don’t risk.

Privacy isn’t a promise. It’s our design.

A psychologist’s file is one of the most sensitive educational records belonging to a student. Sightline is built on one privacy rule: we never ask for a copy.

Student records stay encrypted on your computer. The AI runs there too. We hold no copy.
