Does your proposal turn up with a covering letter, or does it just start at the price? The letter is the first thing a buyer reads, and it frames everything after it. It has to name the job, show you understood the brief, then get out of the way. Proposal Cover Letter drafts it properly, instead of the rushed version written ten minutes before the deadline.
Short answer: Proposal Cover Letter is a free AI writer that drafts the letter sitting in front of a proposal or bid. Set the tone, the length, the formality and who is receiving it, then generate a version you can edit.
What is Proposal Cover Letter?
It is a free tool on EizTools that writes the one page introduction to a proposal, tender or quote. You describe the job, the client and what the letter should do. Back comes a draft with a greeting, a short case for why you fit, and a close that says what happens next.
Straight to a draft
Describe the job in a sentence or two and the letter arrives complete, from the greeting down to the sign-off.
Tone you control
Eight tones, from Formal through Diplomatic to Grateful. The Assertiveness slider decides how hard the letter pushes for a meeting.
Letter shape handled
Toggles add a formal greeting, a sign-off, your contact details and an enclosures note. Leave one off and it is skipped.
Out in your format
Copy it into your document, or download a Word file for the bid pack.
How Does Proposal Cover Letter Work?
You get one screen, and the brief goes in the big box at the top. Its placeholder reads "Describe what you want your Proposal Cover Letter to produce…". The selector underneath is arranged by provider, so moving the same brief from Google Gemini to another family costs one click. Tone, Length, Formality and Recipient live in the advanced options accordion. Each select opens on None, which is less a blank than a delegation to the model.
Generate, and the letter appears in the output card with pills showing the model, a running word count and an estimated reading time. Play it back once with Listen before you export anything, since a letter that sounds stilted aloud will read stiffly on paper too. Anything generated in this session reopens straight from the activity history panel.
Who Is the Letter For?
The Recipient setting quietly rewrites the draft. Pick the one that matches the organisation, not the person who forwarded you the brief.
| Recipient setting | What changes in the draft |
|---|---|
| Individual | Named greeting, warmer close, fewer credentials |
| Company | Business register, references the commercial fit |
| Government | Formal wording, quotes the tender reference, lists enclosures |
| Nonprofit | Mission led opening, value for money instead of margin |
Bidding for a Council Grounds Contract
Picture a grounds maintenance firm bidding for a three year council contract. The prompt: "Cover letter for tender GM-2291, grounds maintenance across 14 council parks. We hold the neighbouring borough contract, run electric mowers and employ local staff."
Set Tone to Formal, Length to Short (150-250w), Formality to Business and Recipient to Government. Switch on Include Formal Greeting, Include Formal Sign-off and Include Enclosures Note. The draft opens "Dear Procurement Team, we are pleased to submit our response to tender GM-2291…" and closes with the enclosures in order.
- ✅ Quote the tender reference in line one
- ✅ Name who will run the work
- ✅ Close with a follow-up date
Match the paperwork Public sector bids are scored against a checklist. Put the reference number, the lot and the submission date in your prompt so the letter repeats them, then check it against the invitation to tender.
Draft as often as you need to on EizTools, a free AI platform that runs in the browser and never asks you to create an account. Each generation starts with your choice of model, whether you want Anthropic Claude on the job or one of the other families. The letter is only the front door, and the Proposal Generator writes the longer document behind it.
Frequently Asked Questions
How long should a proposal cover letter be?
One page is plenty. Short (150-250w) fits most private sector bids, and Medium (300-450w) suits complex tenders, where you have to show you understood a long brief before you get to the price.
What does the Formality select change?
Sentence construction and vocabulary. Legal tightens the wording and drops friendly asides. Casual allows contractions and a first name. Diplomatic softens anything that could read as pressure on the reader.
Can it write an unsolicited proposal letter?
Yes. Say so in the prompt and explain how you found the organisation. The draft will open by earning attention rather than referring to a request that never actually happened.
Should I still edit the result?
Always. The tool only knows what your prompt told it, so names, dates and reference numbers all need checking, and one specific line about this client will lift the letter noticeably.
A cover letter earns its place when it proves you read the brief. Put the client's own words in your prompt, keep it short, and let the proposal carry the detail. Proposal Cover Letter gets you a solid draft, and if the work will run under a signed scope, the Consulting Agreement Draft is a sensible next stop.
