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.
One tool, start to finish.

Record, time, total, and draft, all in one place, so nothing is retyped and nothing is lost between steps.

The Sightline recording screen during a partial-interval session: a running interval clock, the current activity, scoring controls for two behaviors with their interval grids, and session notes and a timestamped observation log beside them.

Your analysis is ready before you’ve left the room.

The moment you stop scoring, Sightline calculates the results and breaks them down by activity, so you see where the behavior concentrates, not just how often it happened.

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.

  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. Stay organized, not scattered.

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

    A student’s session list in Sightline: four observations grouped by month, each tagged with the method that produced it, its duration, and the behaviors recorded.

One workflow, eight methods.

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

iPhone companion

Record from your phone.

Need to move around the room, record outside, or step away from the computer? Your phone picks up the session.

Remote scoring
Scores, activity changes, and notes land in the desktop session in real time.
On its own
The phone runs the whole observation and hands it off to the desktop when the two reconnect.
Voice notes
Speak a note mid-session. It’s transcribed on your desktop, not by a cloud service.

A phone-only observation stays on the phone until it hands off to your computer over encrypted Bluetooth, then deletes itself.

On-device AI

The AI runs on your computer.

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.

No account, no upload. That’s true on the trial too.

  • Observation summaries

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

  • FBA analysis

    Sightline computes the likely function of the behavior from the ABC entries you coded. The AI helps you draft summary statements and session narratives from that analysis, and you assemble the FBA.

  • Cross-session analysis

    How a behavior changed from baseline through intervention, and a synthesis of every observation of the student.

Student privacy

Sensitive work belongs on devices you control.

The record you build is a file on your own machine. Protected student information never touches an online server, there’s no account behind the app, and Sightline never receives your student data. It leaves your machine only when you export or share it yourself.
