Claude and ChatGPT both handle all three jobs competently: a first-draft contract from your own terms, a firm but friendly client email, and captions in your voice. Neither wins on every task. The better one is whichever needs fewer edits on your documents, so run identical prompts on both and score the results.
I am not going to give you a winner from a single run, because model versions change roughly monthly and a result from last week can be wrong today. What lasts is the test: three tasks, fixed inputs, a scoring sheet and a privacy check. It takes about forty minutes and costs nothing on the free tiers of both.
The test: same inputs, two assistants, one scoring sheet
A fair comparison needs the same words going in. Open a fresh chat in each assistant, paste identical prompts, and do not nudge one with follow-ups the other did not get. Run each task twice, because a single output can be lucky.
Use the free tier of each first. The list prices, as of October 2026: ChatGPT has Free, Go at $8 a month, and Plus at $20; Claude has Free, Pro at $20 a month or $17 a month billed annually. Free tiers cap how much you can send, so spread the test over two sittings if you hit a limit. If you want the wider model comparison, ChatGPT, Claude and Gemini compared head to head covers it, but a photographer's decision turns on your own documents rather than benchmarks.
Score every output from 1 to 5 on the same criteria:
- Accuracy: did it include every term I asked for and invent none?
- Voice: would I send it with light edits?
- Structure: can a client scan it?
- Restraint: did it avoid promising things I did not offer?
- Edit time: minutes until I would send it.
Task one: a portrait-session contract
Contracts are where the stakes are highest and where assistants tempt you most. A photographer's agreement usually covers the booking and deposit, what is delivered and when, copyright and the licence the client receives, cancellation and rescheduling, and what happens if the photographer cannot attend. Give the assistant your actual terms; do not ask it to guess them.
Draft a one-page portrait session agreement in plain English for a
solo photographer. Terms to include exactly as stated, no others:
- Session: 90 minutes, one location, up to 2 outfit changes.
- Fee: $450, of which a $150 non-refundable deposit books the date.
- Balance due 7 days before the session.
- Delivery: 30 edited digital images within 14 days, via online gallery.
- Licence: the client may print and share online for personal use;
commercial use needs written permission. Copyright stays with the
photographer.
- Reschedule: free with 72 hours' notice, once.
- Cancellation within 72 hours: deposit forfeited.
- If the photographer cannot attend: full refund or a new date.
Use short numbered clauses. Mark anything you are unsure about
with [CHECK]. Do not add clauses I have not given you.Look for three things when you score it. First, whether any clause appears that you did not ask for, such as a liability cap or an indemnity, which an assistant may add from habit. Second, whether it flags uncertainty with [CHECK] as instructed. Third, whether the plain wording survives: "forfeited" is fine, "hereinafter" is not.
An illustrative failure: the draft says images are delivered "within 14 days of the session" in one clause and "within two weeks of editing" in another. They are not the same promise. A careful read catches it; a skim does not, which is why you should read every clause aloud once.
A clause audit you can run on either draft
After the draft arrives, run a second prompt in the same chat that asks the assistant to check its own work against your list. This catches more than rereading does, because it is mechanical.
Check the agreement above against my terms. For each of these eight
terms, quote the clause that covers it, or write MISSING. Then list
any clause that is NOT in my terms. Then list any two clauses that
could be read as contradicting each other.Record the result in a table of your own. A filled-in example for one draft:
| My term | Clause found | Verdict |
|---|---|---|
| $150 non-refundable deposit | Clause 2 | Covered |
| Balance due 7 days before | Clause 3 | Covered |
| 30 edited images in 14 days | Clauses 4 and 9 | Two different deadlines, fix |
| Personal-use licence | Clause 5 | Covered, but "social media" not named |
| One free reschedule | Clause 6 | Covered |
| Photographer cannot attend | None | MISSING |
That missing row is the realistic failure. Assistants leave out the unhappy-path clauses, the ones about what you owe the client when things go wrong, because your prompt phrased them as an afterthought. Put them first in the terms list next time, and note which assistant caught its own gap when asked.
Two extra clauses photographers forget to ask about
- Model release and portfolio use. If you want to show the client's images on your site, the agreement needs a separate, explicit permission, with an opt-out. Do not let an assistant bury it inside the licence clause.
- Backups and loss. State how long you keep the files after delivery. A vague "we keep your photos safe" is a promise you may not be able to keep.
What no assistant can do for you
It cannot know which clauses are enforceable where you and your client live, how your jurisdiction treats non-refundable deposits, or how copyright transfers work for commissioned portraits. Before you send a drafted contract to a paying client, have a solicitor or an adviser familiar with your market read it once. That cost is small against one dispute, and you can reuse the document for years.
Task two: three awkward client emails
Emails test tone. Give both assistants the same three situations and see which draft you could send fastest.
- Chasing a late balance. The balance was due a week ago and the session is in six days.
- A request for all the raw files. You deliver edited images only.
- A client unhappy with the edit. They say the skin tones look orange.
Write an email from me, a portrait photographer, to a client whose
$300 balance was due 7 days ago. The session is in 6 days. Tone:
friendly and firm, no apology for asking. Mention that the date is
held until the balance arrives and give two ways to pay. Under 120
words. Use [first name] and [your name] as placeholders.Illustrative good output: "Hi [first name], a quick reminder that the $300 balance for your session on [date] was due last week. I'm holding your slot until it arrives. You can pay by card through the link below or by bank transfer using the details on your invoice. Once it's in, I'll send a short reply so you know it's confirmed. Thanks, [your name]."
What to fix: assistants often add a line such as "I hope this email finds you well" or an apology you told them not to include. Delete it, and note in your scoring which assistant needed more deleting. For the awkward ones, paste the client's actual message with names removed and ask for two versions, one that offers a reshoot of one set of images and one that holds the line. Our wider guide to handling photographer client emails with AI goes through the full inbox.
A before and after for the raw-files request
Clients ask for raw files for innocent reasons, often because they want to edit them for a keepsake or they worry about quality. A first draft from an assistant sometimes reads like a policy notice. Here is an illustrative before and after.
Before (typical first draft): "Unfortunately, our policy does not permit the release of unedited raw files. Our editing process is an integral part of our artistic vision, and raw files do not represent the final product."
After (your edit): "Hi [first name], I don't release raw files, because they're unfinished: no colour work, no retouching, and the lighting looks flat until the edit. What I can do is send the full edited set, and if there's a particular look you're after, tell me and I'll do one round of adjustments. Would that work? [your name]"
The after version answers the question the client is really asking, which is "will I get what I want?", rather than defending a policy. Score both assistants on how close their first draft is to the second version. If you give each the sentence "the client is worried about quality, not trying to cut me out", the drafts usually improve markedly, which says something about the value of one line of context.
Check the edit-request reply for promises
The risk in dispute emails is an accidental promise. If the draft says "I'll happily redo the whole gallery" and your terms allow one revision round, you have just offered more than you owe. Scan every verb of commitment: refund, redo, reshoot, discount.
Task three: captions, alt text and a month of posts
Captions are the lowest-risk task and where speed matters most. Give the same three photos' descriptions to both assistants. You do not need to upload images to compare writing, and describing them in words keeps client faces out of the prompt.
Here are five of my past Instagram captions (voice sample):
[paste five]
Describe my style in three bullet points. Then write three captions
for a golden-hour couple's session at a quiet beach. Each under 40
words, one question, no hashtags. Then write one alt-text line for
each, under 125 characters, describing what is in the photo for
a screen reader.Score on voice first. Then check the alt text, which is a separate skill: it should say who and what is in the frame ("two people laughing on a beach at sunset, the tide behind them") rather than praise it ("stunning romantic moment"). Of the three tasks this is the one where both assistants usually need the least editing, and the one where your voice sample makes the biggest difference.
A month-of-posts variant: paste your booking calendar and ask for twelve caption ideas that fit your sessions that month, each tied to a real session type. This is an idea list rather than finished copy, so score it on usefulness.
A caption before and after
Raw first drafts for a beach session often read like a greeting card: "Golden hour magic with these two. Love is in the air! Book your session today." A voice sample fixes the register. After pasting five captions that are dry, specific and slightly self-mocking, an edit might arrive as: "We lost the light twice, once to a dog and once to a very determined gull. These two didn't mind. Do you want your session to be this unplanned?" Count how many edits each assistant needs to get from the first form to the second, and note whether it copies your phrases too literally. Reusing your own jokes in every caption gets noticeable within a week.
One photographer's scores for Claude and ChatGPT
Here is an illustrative sheet for one photographer. The numbers are an example of how to record results, not my measurements.
| Task | Claude: accuracy / voice / edit minutes | ChatGPT: accuracy / voice / edit minutes | Note |
|---|---|---|---|
| Contract | 4 / 3 / 15 | 4 / 4 / 20 | One added a liability clause I did not ask for |
| Late-balance email | 5 / 4 / 3 | 5 / 4 / 4 | Both needed a greeting line deleted |
| Unhappy-client reply | 4 / 4 / 8 | 3 / 4 / 10 | One offered a full redo |
| Captions plus alt text | 4 / 4 / 6 | 4 / 5 / 5 | Voice sample changed everything |
Add up edit minutes: 32 against 39 in this example, so a seven-minute gap per session. At twelve sessions a month that is under ninety minutes, which tells you the choice matters less than the habit of using either one. If your results are this close, pick the one whose interface you prefer, or whichever fits tools you already use.
Privacy settings before the first paste
Contracts and client emails contain names, addresses, dates and sometimes children's details. Do these before you start:
- On consumer plans of both assistants, find the model-training switch in privacy settings and turn it off. Labels change, so look for the setting that mentions using chats to improve the model.
- Know the retention. Anthropic's consumer retention is 30 days with training off and up to five years with it on. ChatGPT's temporary chats are kept for up to 30 days.
- Use placeholders: [client], [venue], [date]. Fill them in after you copy the draft out.
- If you take on an assistant for a studio with staff, business plans from both vendors do not train on your content by default. Check the current terms before you rely on that.
- Never paste a client's payment details, passport numbers or anything about a minor.
A realistic mistake: a photographer pastes a full client email thread, with a home address and a child's name, into a free account with the training switch on. Nothing visibly goes wrong, which is exactly why the habit of placeholders matters. You cannot see a privacy lapse; you can only prevent it.
Which tasks to delegate first, and which to keep
From the three tasks, a sensible order for a solo photographer is captions first (low risk, immediate saving), routine emails second (templates for deposit reminders, gallery-ready notices, review requests), and contracts last (high stakes, rarely rewritten). Keep client conversations about grief, sensitive family situations or complaints in your own words, using the AI only to tidy your draft.
The assistants can also get you from enquiry to quote faster, which our tutorial on same-day quotes and shot lists from a brief shows, and wedding specialists have a set of prompts of their own in the ChatGPT prompts for wedding photographers tutorial.
Save the winners as reusable instructions
Once a prompt works, store it. Claude has Projects and ChatGPT has Projects; either can hold your standard terms and voice sample so you do not paste them each time. Custom GPTs are being retired, so build on Projects instead. Keep a plain-text copy of each good prompt as well, so you are not tied to one assistant when prices or terms change.
A concrete set-up for a Project, in either assistant, takes about fifteen minutes:
- Create a Project called "Studio admin".
- Add your standard terms as a text file, with the unhappy-path clauses at the top.
- Add the five voice-sample captions and three emails you were proud of.
- Write one standing instruction (custom project instructions are a paid-plan feature on Claude): "Use en-GB spelling, keep emails under 150 words, never offer refunds or discounts, mark uncertain points with [CHECK]."
- Start each task as a new chat inside the Project, so the context is there but old threads do not clutter it.
What the subscription is worth to a solo studio
Take an illustrative studio running fifteen sessions a month. If the assistant saves ten minutes on each session's admin (reminders, the contract tweak, gallery notice, review request) that is 150 minutes, or two and a half hours. A $20 plan costs the same as roughly a fifth of an hour at a $100 hourly rate, so the plan pays back if it saves even twelve minutes a month. That sum is why a paid plan is rarely the sticking point; the real cost is the time it takes to read and edit each draft honestly. If you find yourself sending drafts unread, the saving has become a risk, and the answer is to slow down rather than switch tools.
Three mistakes that show up in week two
- Drift in the contract. You regenerate the agreement for a second client and the wording changes slightly, so two clients now hold different terms. Keep one master file and edit it by hand; use the assistant to compare versions, never to produce a fresh one each time.
- Over-friendly reminders. A tone that is perfect for a nervous bride can read as weak when chasing a $300 balance. Give a tone instruction in every email prompt.
- Caption sameness. After twenty captions the openings start to match: a scene, a question, a call to action. Ask for three structurally different options each time and pick the odd one out.
When the answer is "neither yet"
If your edit time is higher than writing it yourself, stop. That happens with highly personal emails and with contracts for unusual work, such as commercial licensing with several usage tiers. In those cases the assistant is still useful as a checker: paste your own finished draft and ask "which of my clauses contradict each other?" or "what question would a client ask after reading this?". Checking your own work is a smaller task than drafting, and the results are easier to trust.
Run the forty-minute test once, record the sheet, and repeat it in three months, because the numbers will have moved.
Questions photographers ask about Claude and ChatGPT
Can I use an AI-drafted contract without a solicitor?
Use it as a first draft, not as the final document. A person who knows contract law in your market should read the clauses on liability, copyright and cancellation before you send it to a paying client. The AI is good at structure and plain wording, and weaker at knowing what is enforceable where you work.
Which is cheaper for a solo photographer, Claude or ChatGPT?
At list price both have a free tier and a $20 a month paid plan, with Claude also at $17 a month billed annually and ChatGPT offering an $8 Go tier. Start free, run the test below on both, and pay for only the one you reach for. Many photographers need neither paid plan.
Should I paste client names and addresses into a chatbot?
Avoid it where you can. Use placeholders such as [client] and [venue], and keep identifiable details out of the prompt. If you use a consumer plan, switch off the model-training option in privacy settings first, and read the retention wording before pasting anything sensitive.
Will AI captions sound like me?
Only if you show it your voice. Paste five of your own past captions as examples, ask it to describe your style, then ask for new captions in that style. Edit the first batch heavily, and the later ones need less editing.
