Completing your Function Report,
one question at a time.
The 3373 Assistant lives inside Claude and walks you through the SSA‑3373 in plain language, in your own words, from a blank page to a signed‑ready PDF.
Works alongside Claude. No coding, and no separate forms to track down.
The SSA‑3373 asks you to explain, in your own words, exactly how your condition affects an ordinary day. It's long, it repeats itself, and the wording trips up people who have nothing wrong with their case, only with the form.
The 3373 Assistant doesn't write your answers for you. It helps you say what's already true, clearly enough that Social Security understands it the first time.
It fills out one form. It doesn't replace your advocate.
If you already have an attorney or a representative, keep them. They handle your case, your appeals, your strategy. The 3373 Assistant only handles one piece: the SSA‑3373 Function Report itself, a form that carries real weight in a disability claim and is just as easy to get wrong as it is important to get right.
That's exactly why it's worth mentioning to whoever's helping you. A Function Report that's already thorough and in the claimant's own words gives your advocate a stronger starting point, not more work to redo.
Everything you need to finish one report.
Four things happen inside a single Cowork session, with no separate accounts and no forms to download ahead of time.
Answer in a natural back‑and‑forth instead of filling in boxes one by one. The assistant asks, you talk, the form fills itself in behind the scenes.
A gentle review that catches the blanks and small slips that often get a report sent back, before Social Security ever sees it.
Begin with the simple, factual questions and work up to the harder ones about limitations at your own pace, not the form's.
When you're done, the official SSA‑3373 PDF is filled out automatically, ready to open, read over, print, and sign.
There's no wrong way to start.
When you begin, the assistant asks how you'd like to go through the form. Every path fills out the same report; pick whichever sounds easiest today.
A handful of friendly, open questions about your health, a typical day, and getting around. Best if writing feels like a choreand you'd rather just talk.
Every question, one at a time, in the same order as the paper form. Best if you like to be thorough and want to see each one exactly as it appears.
The simple, factual questions first (your name, where you live, your pets), building to the harder ones last. Best if the form feels overwhelming.
It checks the form before you do.
When your answers are in, the assistant reviews everything and shows you what it found: one at a time, sorted into three friendly levels, never buried in a wall of red ink.
Before we generate the PDF, here are 3 ways to strengthen Maria's form:
For each one, you can fix it now, skip it, or ask why it matters. When you fix something, the assistant asks a follow‑up question. It never rewrites your words for you.
Say it in your own words.
“My back is shot. Some days I can barely get off the couch.”
That's exactly what goes on the form. The assistant keeps yourwords and won't turn them into stiff, official language. A report that sounds like you is clearer, and more believable, than one full of medical jargon.
Four steps, start to finish.
No prior experience with Claude needed. Setup happens once; every claimant after that starts at step three.

Do I have to finish in one sitting?
No. Your progress saves automatically. Stop whenever you like and type /interview-claimant resume to continue later.
Can someone help me fill it out?
Yes. A family member, friend, or case worker can sit with you and help. The form has a place to note who completed it.
What if I don't know an answer?
Say you're not sure and move on. You can always come back to it before you create the final form.
Is this the official form?
Yes. The assistant fills out the official SSA‑3373 PDF for you to print, sign, and submit to Social Security.
What about my private information?
Your answers are used only to complete your SSA‑3373. As with any sensitive paperwork, keep the finished form somewhere safe.
Is this legal advice?
No. The 3373 Assistant helps you complete the form clearly and completely. It is not a substitute for advice from an attorney or representative. If you'd like to talk to a disability attorney, a service like Atticus (opens in a new tab) can help connect you with one.
Ready when you are.
