AI for Business — 33 tools that read, sort and write for you

AI for Business

33 tools for the work every business does by hand. Read an invoice into a spreadsheet. Sort a bank statement into ledgers. Clean a customer list. Write the letter, the listing, the post, the ad, the landing page. Summarise the contract before you sign it.

How these are different from the rest of the site

Everything else on 1234Tools runs on your device and never sends anything anywhere. These cannot: they need a language model, and that runs on a server. So each of these pages says exactly what it will send before you press the button — the text of the invoice, the rows of the statement — and the file itself is read on your device and never leaves it.

You need an account, because calls are counted: 10 a month free, with no card, and 300 a month on Pro. We store the count, not what you sent or what came back. The model is Anthropic’s Claude, through our own gateway; your text is not used to train it. The details, in the privacy policy.

Question Paper GeneratorA full question paper from your blueprint — sections, general instructions, marks against every question — with a separate marking scheme that gives the model answer and where each mark is earned.Lesson Plan & Worksheet WriterA lesson plan you could hand to a cover teacher — objectives in observable verbs, a timed sequence, the misconceptions to expect and what to say to each — with a printable worksheet and its answer key.Report Card Comment WriterPaste the class list with marks, attendance and a few words about each pupil, and get a report card comment for every one of them — in their own name, about their own term, with the next step spelt out.Marking Rubric & Assessment Criteria BuilderA marking rubric for a task you set — criteria against bands, with descriptors that actually tell a 7 from a 5, the marks allotted to each criterion, and a note on what a top answer does.Parent Communication WriterThe message home, written properly — absence, progress, behaviour, fees, trips, exams, closures — in the shape of the channel you are sending it on, and in a second language if the family reads one more easily.Textbook Question ExplainerPaste the question you are stuck on — one, or a whole exercise — and get the method worked through step by step, the idea it rests on, the mistake most people make, and a similar question to try with its answer.SEO Title, Meta & Outline WriterGive it a page topic, who it is for and the keyword you want to rank for; get back a title that fits in the search result, a meta description that fits under it, an H1, an H2 outline, the questions people ask, where to link from — and a note on what the searcher actually wants.Blog Post WriterA brief in, a finished post out: headings, an introduction that says what the point is, and a summary at the end. British spelling and no invented numbers — anything it cannot support is marked [source needed] for you to fill in or cut.Google & Meta Ad Copy WriterOne offer in; a full set of ad copy out — 15 Google responsive search ad headlines and 4 descriptions, 3 Meta primary texts and 5 headlines — each written short of its character limit, counted here in your browser, and flagged if one slips over, as a table you can paste straight into the ad platform.Email Campaign WriterA launch, an offer, a win-back, a newsletter or an onboarding series, written from your facts: five subject lines with preview text, the email itself, a plain-text version, the call to action — and a three-email sequence when you ask for one.Brand Voice Guide BuilderPaste two or three pieces of copy you already like and say what the brand is; get back a voice guide — the personality in three words, a tone do/don’t table, words to use and words to avoid, your samples rewritten to show the rules, and how the voice changes for social, support and sales.Landing Page Copy WriterProduct, audience, offer and proof in; a landing page out — hero headline and subhead, three benefit blocks, how it works, the objections answered, testimonial slots marked [quote needed], an FAQ and five calls to action — written from your facts and nothing else.Scanned Invoice & Receipt ReaderPhotograph or scan an invoice or receipt and get the vendor, numbers, dates, taxes and every line item back as a table you can download — the picture is read directly, so a scan with no text layer works.Expense Receipts to SpreadsheetPhotograph up to four expense receipts at a time and get one row per receipt — date, merchant, category, amount, tax, currency and how it was paid — as a CSV or Excel file for the expense claim or the books.ID & KYC Document ReaderPhotograph a PAN card, Aadhaar (front), passport, driving licence, GST certificate or cheque and get the typed fields back — document type, name, number, dates, address — with a checklist of what to verify before you accept it.Quotation & Proposal WriterThe facts of a deal — who it is for, what you will supply, the prices, the terms — written up as a quotation or a short proposal: a numbered line-item table, totals with tax, validity and the terms spelt out, ready to paste onto your letterhead.WhatsApp Business Template WriterSay what the message is for and what changes per customer, and get three to five WhatsApp Business message templates in Meta’s format — {{1}} placeholders, a category, sample values, buttons — with a note on what gets each one rejected at review.Customer Review ResponderPaste the reviews — one per line, or a CSV export — and get, for each one, the sentiment, the issue in a few words, a reply in your voice ready to post, and what to fix inside the business, as a table you can download.Contract, NDA & Offer Letter GeneratorName the parties and the terms and get a full first draft — a mutual or one-way NDA, a service or consultancy agreement, an offer letter, a leave-and-licence summary — with numbered clauses, defined terms and [brackets] where you still have to decide. A draft for your lawyer, not a substitute for one.Job Description WriterThe facts of a role — title, what they will do, what they must have, pay, where and when — written into a job description with responsibilities, requirements, nice-to-haves and a salary line, then checked for wording that puts good candidates off.CV Screener against a Job DescriptionPaste the job description and up to five CVs and get, for each candidate, a fit score with the reasoning, the requirements they meet, the gaps, and the questions to ask at interview.

What they are good at, and what they are not

Reading and structuring — invoices, statements, contracts, notes — is where they save hours. The output is a first draft of data entry or of a document that you check, not a replacement for checking.
Writing from facts works well when you give the facts. Anything missing comes back as a bracketed placeholder rather than an invention; that is deliberate.
Tax and legal questions get honest confidence levels and a list of what to check. They are a fast route to the right neighbourhood, not a filing or a legal opinion.
Scanned documents are read as pictures by the Scanned Invoice & Receipt Reader, the Expense Receipts tool and the KYC Document Reader: the resized picture itself is sent, so cover what should not travel before you photograph it. A typed or exported PDF is still better fed to the text tools, which send no picture.

Frequently asked questions

Why do I need an account for these and nothing else?

Because these cost money each time they run and the free allowance has to belong to someone. The account does nothing else: it is an email address, a plan, and a count. Every tool that runs in your browser stays free and anonymous.

Is my data used to train the model?

No. Calls go through our gateway to Anthropic’s API, whose terms exclude API data from training. We do not store your inputs or the outputs.

What happens when the free calls run out?

The tool tells you, with the date they reset, and points to the plans. Nothing is charged without you choosing a plan.

Which tools are coming next?

A GST return reconciler, batch runs over whole folders for Pro, and Tally-direct import for the categoriser. The order depends on what people ask for — the contact page works.
