Construa um rastreador de concorrentes

Add a competitor tracking section to this private internal app.

Create an entity called "Competitor" with these fields: name; website URL; what they sell, in one line; who they serve; location or service area; the reason I consider them a competitor, as long-form text; a "threat level" I choose from high, medium or watch-only; date added; and an "active" flag so I can retire one without deleting its history.

Build a page listing all competitors, sorted by threat level then name, showing name, what they sell, threat level and when I last recorded anything about them. Add a form to create and edit one.

Two things I want the form to push me on, because this is where a list like this usually goes wrong:
- The "reason" field is required. If I cannot say why someone is a competitor, they are not one.
- Show a warning, not a block, once I have more than eight active competitors: "A list this long usually means you are tracking your industry rather than your competitors."

Do not fetch anything from the internet in this step and do not pre-fill any competitor for me. I will enter them myself.

Add pricing and offer tracking to the Competitor section.

Create an entity called "Offer" linked to a Competitor, with: offer name; price; price unit (choose from per hour, per job, per month, per person, per item, from-price, or not published); what is included, as long-form text; what is explicitly excluded; any minimum; the URL the price came from; the date I recorded it; and a "still current" flag.

A competitor can have several offers. On the competitor's page, list their offers with the date each was recorded.

Build a comparison page showing all competitors' offers side by side, grouped by price unit so I am not comparing an hourly rate to a monthly one. Let me add my own prices as a special entry marked "us" so I appear in the comparison.

Important: "not published" is a real and common answer, and I want it recorded as a finding rather than left blank — a competitor who hides pricing is telling me something. When the price unit is "not published", let me record what they say instead, for example "call for a quote".

Do not estimate, infer or guess any price. Only store what I enter.

Add an observation log to the Competitor section.

Create an entity called "Observation" linked to a Competitor, with: date, defaulting to today; type, chosen from price change, new service, dropped service, marketing change, review or reputation, hiring, closure, or other; what I observed, as long-form text; where I saw it, as free text or a URL; and "what I think it means", as a separate long-form field.

Keep "what I observed" and "what I think it means" as two distinct fields, and label them clearly. I want to be able to read back what actually happened without my interpretation mixed into it.

Show observations newest first on each competitor's page, and build a combined timeline page across all competitors with a filter by type and by competitor.

Adding an observation should take one click from anywhere in the competitor section. Observations can be edited and archived but never hard-deleted.

Also add, to the app's existing Log Entry section, the ability to link an entry to a Competitor, so a decision I record there can point at what prompted it.

Add a positioning page to the competitor section.

It should take everything already stored — my Business Profile, my own prices, every competitor with their offers, and the observation log — and produce a written summary covering: where I sit on price against each competitor for comparable work; what I offer that none of them appear to; what they offer that I do not; and which competitors have moved recently and in which direction.

Rules for how it writes:
- Use only what is stored in this app. Do not add market knowledge, industry statistics or anything from the internet.
- When something is missing — no price recorded, no recent observation — say so plainly instead of filling the gap. "No price recorded for X since January" is a useful sentence.
- Quote my own stored numbers exactly. Do not round or convert them.
- Keep it under 500 words and write it as plain assessment, not marketing copy.

Let me save a generated summary with the date it was made, and keep past ones, so I can see how the picture changed over time.

Show clearly on the page how many competitors, offers and observations the summary was built from, so I can tell at a glance whether it is standing on real material or on three records.

Add an automated weekly check to the competitor section.

On each Competitor, let me nominate up to three URLs to watch, each with a label such as "pricing page" or "services page". Only pages I nominate — nothing else.

Create a backend function that fetches each nominated URL, extracts its readable text, and compares it to the text stored from the previous check. Store each check with its date, so there is a history.

When the text has changed, have it produce a short plain-language description of what changed — focusing on prices, services added or removed, and claims made — and ignore navigation, cookie banners, dates and other boilerplate that changes without meaning anything.

Run this once a week on a schedule and email me a digest containing only the competitors where something changed, with a one-line description each and a link to the page. If nothing changed anywhere, send nothing.

Give me a manual "check now" button as well, so I can test it without waiting a week.

Every detected change must also appear as a draft Observation linked to that competitor, with type "price change" or "other", which I then confirm or discard. Do not write a confirmed observation automatically — I decide what counts.

Be conservative about frequency: once a week per page, never more, and identify yourself honestly in the request.
