Best AI for essays

Use AI to think, research and get feedback on your essay, then write it in your own words. Check your class rules first; many schools allow brainstorming and feedback but not AI-written text. All five picks have a free plan. Start with one chatbot for planning and feedback, add a source tool for research, and finish with a proofread.

// ready-to-paste prompt

Try this prompt

Here is my essay prompt and rubric: [paste]. Here is my draft: [paste]. Do not rewrite it. Give me feedback in three parts. 1) Is my thesis clear and arguable? 2) Which paragraphs do not support it, and why? 3) Quote the 3 sentences that are hardest to follow and explain what is unclear, so I can fix them myself. End with one question a skeptical reader would ask.

// use cases

Ready-to-paste prompts for these tools

ChatGPT

Snap the inside of your fridge and get meals that use up what's about to expire first.

Use cases you didn't know about

Photograph your fridge, get a 3-day meal plan

Who it's for: Anyone who throws out wilted veg every week
Tool to use: ChatGPT · Open ChatGPT ↗

prompt · fill in the [brackets]

I'm attaching [1-3] photos of my fridge and pantry. First, list every ingredient you can see, and mark anything that looks like it needs using in the next 2-3 days (soft produce, opened dairy, leftovers, meat near its date). Ask me to confirm anything you're unsure of.

Then make a 3-day plan (breakfast, lunch, dinner) for [number] people that:
- uses the at-risk items on day 1 and 2
- needs at most [5] extra items from the store (give me that shopping list)
- fits [diet/allergies, e.g. no pork, one picky 6-year-old]
- uses [equipment: oven / air fryer / one pot] and takes under [30] minutes on weeknights

Finish with a 10-minute prep-ahead list for tonight.

Steps & tips

ChatGPT accepts photos in the app: tap + and take the picture straight from the fridge.
Open the crisper drawers before shooting; that's where food hides.
When in doubt about whether something is still safe to eat, throw it out. AI can't smell it.

Claude

Have AI read the whole lease and point out anything non-standard before you sign.

Use cases you didn't know about

Upload a lease and flag the unusual clauses

Who it's for: Renters about to sign (or renew) a lease
Tool to use: Claude · Open Claude ↗

prompt · fill in the [brackets]

I'm attaching my residential lease as a PDF. I'm a tenant in [city, state/country]. Please:
1. Summarize the key terms in a table: rent, due date, late fees, deposit, lease length, renewal and notice periods, who pays which utilities, pets, subletting, repairs.
2. List every clause that is unusual, one-sided or worth asking about (e.g. automatic renewal, fees for routine maintenance, broad entry rights, waiving rights, penalties for early termination). For each: quote it, explain in plain English what it means for me, and rate it Low / Medium / High concern.
3. Note anything that may conflict with typical tenant protections in my area, clearly marked as something to verify.
4. Give me 5 polite questions to send the landlord before signing.

Be specific and quote section numbers. Don't give legal conclusions; flag things to check.

Steps & tips

Claude reads PDFs directly: attach the file in the chat.
Remove your ID numbers or bank details from the file first if you prefer.
Informational only, not legal advice. For anything you'd sign or dispute, check with a qualified lawyer or tenant-rights group.

Claude

Upload a medical bill, EOB or utility bill and get a line-by-line plain-English breakdown plus a script to dispute errors.

Use cases you didn't know about

Explain my confusing bill (medical or utility)

Who it's for: Anyone staring at a bill that makes no sense
Tool to use: Claude · Open Claude ↗

prompt · fill in the [brackets]

I'm attaching [a medical bill / my insurer's Explanation of Benefits / a utility bill]. Please:
1. Explain every line item in plain English (what the code or charge means, why it might be there).
2. Show the math: total charged, what insurance or credits covered, what I'm being asked to pay. Point out if the numbers don't add up.
3. Flag likely errors or things worth questioning: duplicate charges, services I may not have received, out-of-network surprises, estimated vs actual meter readings, fees that look unusual.
4. Tell me what documents to request (itemized bill, EOB, meter history).
5. Write a short, polite phone script and an email I can send to the billing department to ask about the flagged items, and ask about payment plans or financial assistance.

Context: [what the visit or service was, dates, my plan type if known].

Steps & tips

Ask for an itemized bill first; summary bills hide the codes.
Black out your member ID and account number before uploading if you prefer.
Informational only, not medical advice. Your doctor or pharmacist has the final word. Informational only, not financial advice. Double-check numbers against your actual statements.

ChatGPT

Upload a statement export and get a list of every recurring charge, price creep and duplicate.

Use cases you didn't know about

Find forgotten subscriptions in your bank statements

Who it's for: Anyone who suspects they're paying for stuff they forgot about
Tool to use: ChatGPT · Open ChatGPT ↗

prompt · fill in the [brackets]

I'm attaching [3] months of bank/credit card statements as [CSV/PDF]. Please:
1. Find every recurring charge (monthly, yearly, weekly) and put them in a table: merchant, amount, frequency, first and last date seen, yearly cost.
2. Flag price increases, duplicates (e.g. two streaming accounts), free trials that turned paid, and small charges that repeat.
3. Total my yearly spend on subscriptions.
4. Sort them into Keep / Review / Probably cancel, based on this: I actually use [list what you use].
5. For each 'Probably cancel', tell me the usual way to cancel (app store, website settings, phone) and whether a cheaper tier usually exists.

Steps & tips

Download the CSV export from your bank's website; it's cleaner than a PDF.
Delete account numbers from the file before uploading if you prefer.
Informational only, not financial advice. Double-check numbers against your actual statements.

ChatGPT

Photograph an old recipe card and get a clean, scaled, metric-or-cups version you can share with family.

Use cases you didn't know about

Digitize grandma's handwritten recipe card

Who it's for: Families saving recipes before the cards fade
Tool to use: ChatGPT · Open ChatGPT ↗

prompt · fill in the [brackets]

I'm attaching a photo of a handwritten recipe card. Please:
1. Transcribe it exactly as written first (keep the original wording, mark anything unreadable as [?]).
2. Then write a clean modern version: ingredient list with both US cups and grams, numbered steps, oven temp in °F and °C, pan size, total time.
3. Translate vague old instructions (e.g. 'butter the size of an egg', 'moderate oven', 'oleo') into exact amounts and explain your guess.
4. Scale it to [number] servings.
5. Suggest [1-2] tweaks for [dietary need, e.g. dairy-free] without changing the soul of the recipe.

Steps & tips

Shoot in daylight, flat, without flash glare.
Keep the original transcription with the photo; family members may read the handwriting differently.
Print the clean version for a family cookbook.

Claude

Turn your current bill and competitor prices into a calm, specific retention-call script.

Use cases you didn't know about

Get a script to lower your internet or phone bill

Who it's for: Anyone whose promo rate quietly expired
Tool to use: Claude · Open Claude ↗

prompt · fill in the [brackets]

Help me call [provider] to lower my [internet/phone/insurance] bill. Facts: I pay [amount]/month for [plan/speed]; I've been a customer for [years]; my promo ended [date]. Competitors near me: [provider + price, provider + price]. I'm willing to [switch / drop a channel package / sign a 12-month deal]; I'm not willing to [lose speed / pay install fees].

Write me:
1. A 30-second opening that asks for the retention/loyalty department.
2. 3 specific asks, in order, from best case to acceptable.
3. Calm replies to the 5 most common pushbacks ("that's the best price", "promo is for new customers", etc.).
4. When and how to say I'm ready to cancel, and what to confirm in writing before hanging up (new price, end date, fees).
Keep it polite and short enough to read on a phone during the call.

Steps & tips

Look up competitor prices for your exact address first; that's your leverage.
Ask for the agreed price in a confirmation email or chat transcript.
Be kind to the agent; they're more likely to find a deal.

Frequently asked questions

What is the best AI for essays?

For planning and feedback, ChatGPT or Claude on the free plan. For finding sources, Perplexity, and for working from your assigned readings, Gemini Notebook. Finish with Grammarly to proofread. Write the final essay in your own words.

Is it cheating to use AI for an essay?

It depends on your school's rules. Brainstorming, outlining and asking for feedback are often allowed; submitting AI-written text as your own often is not. Read your class policy, and if you are unsure, ask your teacher and say how you used AI.

Can AI find sources for my essay?

Perplexity shows a source link with each answer, which makes checking easy. Chatbots can still get details wrong or invent citations, so open every source, confirm the quote and page, and cite the original, not the AI.

Does Grammarly check for plagiarism?

Plagiarism and AI-text detection are Pro features, per Grammarly's plans page (Pro from $12/mo). The free plan fixes spelling and grammar mistakes and shows your writing tone.

What is the best free AI for essay writing?

ChatGPT or Claude's free plan for outlines and feedback, Perplexity's free plan for sources, and Grammarly Free for the final proofread. That covers the whole process without paying.
