AI WRITING PROMPT TOOL
One box. Any instruction. Whatever the other nine modes missed
Magic Mode is the open instruction box: instead of picking one of the nine preset tools, you type what you want done to the text.
Before and after
Type the instruction, in your own words
It is the escape hatch: the place to go when a preset is close but not exact.
You wrote
The sprint slipped because QA found a race condition in the payment retry logic, which took two days to reproduce, and the fix needed a schema change we had to coordinate with the data team.

The instruction is the interface, so you write things like “turn these notes into three bullets”, “make this sound less desperate” or “keep only the sentences with a date in them”.
What makes an instruction work
Every instruction that works has three parts:
- Operation. A verb the text can be acted on with: summarise, split, merge, extract, reorder, convert, rewrite as, keep only, remove every.
- Shape. What you want back: three bullets, one sentence, a two-column table, a subject line, a numbered checklist.
- Constraint. The boundary that makes the result checkable: under fifteen words each, no adjectives, keep the dates, do not change the names, formal register.
“Make it better” has none of the three, so nothing can be right or wrong against it. “Rewrite as three bullets, under fifteen words each, keep the dates” has all three: it either did that or it did not.
The four instructions that fail, and why
- Vague. “Improve this”, “make it nicer”, “professional please”. You get a coin flip you cannot evaluate; name which property changes instead.
- Three operations in one. “Translate this to German, shorten it and add hashtags.” Run them in sequence, so that when the third goes wrong you still have the second.
- Asking for facts the text does not contain. “Add the launch date.” If the date is not in the selection it is not available, so put it in the instruction: “add the launch date, 14 September”.
- Asking for judgement. “Is this good?” returns an opinion you cannot act on. Ask for the change you suspect it needs and compare the two versions instead.
The pattern under all four: an instruction you cannot check is an instruction you cannot rely on.
Instructions worth keeping
A working set, all of them things people run more than once:
- “Turn these notes into three bullets, one line each.”
- “Rewrite as a changelog entry: what changed, who it affects.”
- “Strip every hedge. Keep the facts.”
- “Make this sound less desperate.”
- “Turn this into a subject line under 60 characters.”
- “Rewrite this refusal so it reads as final, not open to negotiation.”
- “Convert this paragraph into a numbered checklist, imperative verbs.”
- “Keep only the sentences that contain a date or a number.”
- “Explain this to somebody who has not been in the project.”
- “Split this into two messages: the decision, then the detail.”
When a preset beats an instruction
The nine presets exist because their instruction is already written and already tuned. Correcting, translating and resizing each carry constraints you would otherwise restate every time: keep the meaning, keep the register, keep the facts, add nothing. Asking Magic Mode to “fix the grammar” is retyping a prompt that already has a button.
One note on cost: Magic Mode and Explanation stay metered on every plan below the top one, while the rest become unlimited earlier. The allowances are on the pricing page.

Step by step
How to give FixMeBot any instruction
Both platforms do the same thing in the same order.
-
Select the text the instruction applies to
Highlight it in any field in the browser or send it to the Telegram chatbot, remembering that Magic Mode acts on that text and nothing else, because it cannot open a link or look anything up.
-
Type the instruction
Say the operation, the output shape and the constraint in one sentence: “rewrite as three bullets, under fifteen words each, keep the dates”.
-
Chain it, do not stack it
Run one operation at a time and use the result as the input to the next, because translating and then shortening in two passes shows you what each step did and leaves you a version to fall back to.
What can I ask Magic Mode to do?
Anything that acts on the text you selected: restructure it, summarise it, extract parts of it, convert it to another format, change its register, or apply a rule you make up on the spot. It cannot browse the web, open a file or look up a fact, because the text you send is the entire material it has.
Can I write the instruction in my own language?
Yes. Write it in whichever language you think in; it applies to text in any of the 90+ languages FixMeBot supports, and the two do not have to match. When you want the result in a particular language, say so in the instruction. That removes the only real ambiguity in a two-language request.
How long can the text and the instruction be?
The text is bounded by the usual per-request limits: 15,000 characters in the browser extension, 4,096 per Telegram message. Keep the instruction itself to a sentence or two. Three stacked instructions is the most common reason a result quietly misses one of them.
How is this different from pasting the text into a chatbot?
The text is already selected and the result lands back in the field you were writing in. No tab switch, no paste out and paste back, no thread to scroll. That is the difference between a tool you use on the sentence in front of you and one you visit.
Write it once. Send it right.
