AI Writer Help: Get Useful Drafts and Better Revisions

Weak AI writing usually comes from a weak brief. Here is how to give an AI assistant the context it needs, diagnose bad drafts, and turn revision feedback into writing that actually fits your purpose.

Updated 5 min read

When AI writing comes out flat, generic, or off-tone, the problem is almost always in your instructions — not in the AI. Give the assistant a clear purpose, a specific reader, examples of the voice you want, and the facts it needs, and the draft improves significantly before any revision.

The other common problem is that good prompts disappear with the chat. Tools like fenbs store reusable writing prompts and accepted style preferences so every new session starts with the same instructions rather than rebuilding them from memory.

Diagnose weak AI writing before you revise

Before asking the AI to try again, name the actual problem. Vague feedback like "make it better" produces a different vague draft. Specific feedback fixes a specific flaw.

  • Too generic: the draft could apply to any company or situation. Fix: give specific facts, names, and numbers from your actual context.
  • Wrong tone: too formal, too casual, or too promotional for the reader. Fix: describe the tone in one sentence and provide an example sentence that hits it.
  • Missing the point: the draft answered a different question. Fix: restate the one thing this piece must communicate in plain terms.
  • Too long: padded with qualifiers and repetition. Fix: give a word count and ask the AI to cut, not summarize.
  • Unverifiable claims: statistics or examples that sound plausible but need sources. Fix: ask the AI to use only facts you provide, or flag anything it cannot cite.

Write a brief the AI can actually use

A good brief takes five minutes to write and saves several rounds of revision. Include five elements: the purpose of the piece, the reader, the voice, the key facts or sources, and the format.

  1. Purpose: what action should the reader take, or what should they understand after reading?
  2. Reader: who are they, what do they already know, and what do they care about?
  3. Voice: formal or conversational, first or third person, long sentences or short. Provide one example sentence.
  4. Facts: the specific claims, numbers, names, or events the piece should include. Do not leave the AI to invent these.
  5. Format: word count, number of sections, heading style, any required elements like a call to action or a disclaimer.

A brief for a client email is shorter than a brief for a report. The level of detail should match the risk: a quickly written email needs less brief than a proposal that will be reviewed by a lawyer.

Use examples to set the voice

Describing a voice in the abstract is hard. "Professional but approachable" means different things to different people and different AI models. The most reliable way to set the voice is to provide an example.

Paste a sentence or paragraph written in the voice you want — from your own previous writing, a piece you admire, or a company style guide — and ask the AI to match it. Then check: is the match close enough, or is the AI interpreting "approachable" as informal slang when you meant warm but precise?

If you write in the same voice regularly, save the example sentences and the description together. The next time you need help with writing assistance, the voice instructions are already documented.

How fenbs helps

Save writing prompts and accepted style preferences

fenbs stores a shared Skills and prompts library that any connected AI assistant reads at the start of a session. Write your writing instructions, the voice description, and the example sentences once and save them in fenbs. Your next session starts with the same guidance — and so does a colleague's — without rebuilding from scratch.

Giving revision feedback that produces better results

After a first draft, good revision feedback is as specific as the original brief. Tell the AI what is wrong and why, not just that it should improve.

  • Quote the specific sentence or phrase that is wrong, then say what is wrong with it: "This sentence implies we are offering a guarantee. We are not."
  • Give the replacement fact or claim, not just the instruction to change: "Replace this with the actual statistic from our internal data: 23% reduction in processing time."
  • Ask for one change at a time when there are multiple issues. A list of five problems often produces a draft that half-solves all five instead of fully solving any one.
  • Ask the AI to explain the logic behind a revision you are unsure about. If the explanation does not make sense, the revision is probably wrong.

When AI writing is not the right tool

AI writing assistance works well for first drafts, structural outlines, and iterating on a piece you understand. It works less well for writing that requires original research, that will be attributed to a named person with a strong established voice, or that involves professional judgment — legal advice, medical guidance, expert analysis.

In those cases, AI can still help: drafting an outline, suggesting structure, or checking for clarity after a person has written the substance. The judgment and the original material come from the person; the AI helps with the form.

How to do this with fenbs

  1. Create a free account and start a project for your writing work.
  2. Add a Skills and prompts note with your best briefs — the purpose, reader, voice, and format instructions that produce the results you want.
  3. Write accepted style preferences — prohibited words, required formats, tone rules — as Decisions and rules so every connected AI reads them first.
  4. Connect your AI writing app to fenbs over MCP from Integrations.
  5. When a prompt produces a result you want to keep, add it to Skills and prompts with a note on when to use it.
  6. Save revision notes as context on the task so the next session knows what was tried and why it did or did not work.

Questions people ask.

Why is my AI writing generic and unhelpful?

The most common cause is a vague brief. Tell the AI the purpose, the specific reader, the voice, and the facts it must include. Provide an example sentence in the voice you want. Generic input produces generic output.

How do I get AI to write in my voice?

Provide an example sentence or paragraph written in your voice and ask the AI to match it. Describing voice in the abstract is less reliable. Save the example with your writing prompts so you can use it in every session without searching for it again.

Can AI help me write something that requires professional judgment?

AI can help with structure, clarity, and drafting. It should not provide the judgment itself for legal, medical, financial, or expert analysis. Use AI to improve the form of writing you have done; supply the professional judgment yourself.

How many times can I ask an AI to revise a draft?

As many times as needed, but diminishing returns set in quickly without changing your instructions. If three rounds of revision have not produced a usable draft, the problem is usually in your prompt. Rewrite your prompt — especially the purpose and reader description — before asking for another draft.

How do I save AI writing prompts for reuse?

Most AI chat apps do not persist prompts between separate sessions. A tool like fenbs stores prompts in a shared library any connected AI assistant reads at the start of a new chat. That means the same brief is available in your next session, a colleague's session, or a different AI app.
