Use cases

Seven ways to start a hunt

Each kind of search starts from a different place: nothing yet, an app that already sells, a free engine, an idea, a market, your own product or one technical problem. The kind decides where the agent looks, what it checks and what you hold at the end.

Updated 26 October 2026

Choose

Which one fits

Start from what you have today. If you are not sure, start without picking one: the agent reads your message as one of the seven and asks before it searches.

Typical figures from the price list. A run sets its maximum aside first, takes only what it used, and returns everything if it fails.

1.1 Find something to build

From anywhere

For builders who would rather start from what people already pay for than from a guess. Give a direction, such as a kind of customer or a platform, or nothing at all, and up to three researched candidates come back.

You bring
Nothing, or a direction in your own words
You get back
Up to three candidates, each with a verdict
Typical cost
About 41 credits

What happens

  1. Turn your words into searchesAnything you pin, such as a field to stay in or a category to avoid, is held exactly as you wrote it.
  2. Search GitHub, a repository index and the webFor engines, products and the complaints around them.
  3. Group the findings into marketsThen look up who already sells in each, because a decision needs names and a count.
  4. Read what the leaders’ own users complain aboutWhere products charge and users complain, demand is proven and the complaints say what is missing.
  5. Go further, if you ask it toIt invents answers to the needs it found, borrowed from other fields, and checks each against what already exists. You choose how far to reach, in one to three rounds.
  6. Keep up to three and research eachWho serves it, what would set it apart and how it could win. The markets it passed on are kept with what it saw there.

What you get

  • Up to three candidates, each in one sentence: what to build and for whom.
  • Who already sells a fix, what they charge and what their users complain about, with a link to each source.
  • A verdict on each: start, narrow or stop.
  • The markets it passed on, and why.

Limits

  • It can end with every candidate passed. A hunt that finds nothing worth building says so, and you pay for the work it did.
  • Ideas from the go further step are marked as ideas and never count as evidence that a market exists.

Pick another when

A first hunt typically costs about 41 credits, and a kept candidate about 15 more to check. From a first hunt to a project and a build brief is typically about 110 credits. These are typical figures, not a promise.

1.2 Find something to build

From a proven app

For builders who prefer proven demand to a new idea. Find up to three apps worth rebuilding, or name one and get one verdict, each with a rebuild case written from the app’s public pages only.

You bring
Nothing, or the name of an app that already sells
You get back
Up to three apps with a rebuild case, or one verdict
Typical cost
About 65 credits

What happens

  1. Find apps with proof of demand, or the one you namedStore figures, extension stores, for-sale listings and “alternative to” threads. If a name fits several apps, it asks which one.
  2. Cut at the gatesA network, licensed content, certification, hardware or anything on your never list ends it, whatever the demand.
  3. Scan each survivor for weaknessThe date of the last version, complaints about price rises and paywalls, platforms it does not cover and what its own users ask for.
  4. Work out where the value livesLocal logic a rebuild can match, a wrapper around someone else’s service, or a server core that cannot be rebuilt.
  5. Size the rebuildThe core job in one sentence, and any open source parts that already do some of it, against your size limit.
  6. Write the case and the verdictFour factors, demand, weakness, feasibility and angle, each graded verified, observed, estimated or unknown, with the link that shows it.

What you get

  • Find mode: up to three apps, each with a rebuild case and a verdict.
  • Check mode: one app, one verdict and the evidence behind each factor.
  • A legal line in the brief: build from public behaviour, never from the app’s code, name, icon or text.
  • The unknowns, each with what would change the verdict.

Limits

  • It never downloads, installs, decompiles or runs the app. A server core that never reaches the client stays unknown.
  • The legal line is a rule for the work, not legal advice. Where it finds a terms clause on reverse engineering it quotes it, and the decision is yours.

Pick another when

Finding apps typically costs about 65 credits and checking one named app about 24. A check, a shaped plan, a project and a brief typically come to about 60. These are typical figures, not a promise.

1.3 Find something to build

From a GitHub engine

For builders who can make an interface people will pay for. It looks for free engines on GitHub that do something hard but need a terminal, then checks who already sells that interface.

You bring
A direction, or a kind of engine
You get back
Up to three candidates built on a named engine
Typical cost
About 41 credits

What happens

  1. Write searches for engines only programmers can runAnything you pin is held exactly as you wrote it.
  2. Search GitHub, a repository index and the webThe index is searched by meaning and by words, so an engine is found by what it does as well as by its name.
  3. Group what came back into marketsA free engine is not a market. What matters is whether people pay for the result, and who sells it today.
  4. Read what the leaders’ users complain aboutThat says what an interface on a free engine would have to do better.
  5. Keep up to three and research eachWho serves it, what would set it apart and how it could win.

What you get

  • Up to three candidates, each built on a named engine.
  • Who would pay for the interface, who sells one today and what they charge, with links.
  • The engine’s licence and when it was last updated.
  • A verdict on each: start, narrow or stop.

Limits

  • It reads repositories and web pages. It does not run the code.
  • It reports each engine’s licence. Whether that licence lets you sell a product built on it is for you to confirm.

Pick another when

A first hunt from an engine typically costs about 41 credits, the same as From anywhere, and a kept candidate about 15 more to check. These are typical figures, not a promise.

2.1 Check what you have

Check an idea

For anyone with a specific idea who wants to know whether it holds before spending weeks on it. It does not go looking for other ideas.

You bring
One idea: who it is for and the job it does
You get back
One verdict, with the evidence behind each part
Typical cost
About 32 credits

What happens

  1. State the idea back in one sentenceThe buyer, the job and how it would be paid for. If your message leaves the buyer or the job open, it asks one question and waits.
  2. Find who serves the need todayPaid products, free tools, open source projects, and the spreadsheet or manual routine people use instead.
  3. Read what they charge and who forFrom pricing pages. The price says whether this buyer pays for software at all.
  4. Look for people asking for itRequest boards, forums, review complaints and “is there a tool that” threads.
  5. Scan the closest products for gapsThe gap your idea would live in has to be one their own users name.
  6. Size the build and name what is unknownThe core job, the parts that already exist and what to find out before you build.

What you get

  • A verdict: worth building, worth building for a narrower buyer, a real need served the wrong way, or no evidence of a need.
  • Who serves the need now, what they charge, who is asking for it and what it would take to ship, each with evidence or marked unknown.
  • A table of who serves the need today: product, price, platform and buyer.
  • The unknowns, each with what would change the verdict and where to look.

Limits

  • It cannot measure demand for something nobody has built. It measures who serves the need today and who has asked for it in public.
  • An empty market is a finding to explain. It looks for the reason: nobody tried, people tried and stopped, or something other than software meets the need.

Pick another when

A check typically costs about 32 credits. A check, a shaped plan, a project and a brief together typically come to about 80. These are typical figures, not a promise.

2.2 Check what you have

Size up a market

For anyone who has a market in mind and wants the map before deciding anything. You get one table of products, the weaknesses their own users name, and where an idea of yours would sit.

You bring
A market or a kind of product
You get back
A market map: every product, its price and its weak spots
Typical cost
About 45 credits

What happens

  1. Find the products that serve the marketThe web, app stores, directories and open source alternatives, searched in the words a buyer would type.
  2. Read price, platform and buyer for eachFrom pricing and product pages.
  3. Scan the five leaders for weaknessesIn their users’ own requests, complaints and paywall grumbles.
  4. Write the map as a documentOne table you can sort and argue with, kept in your project when you name one.
  5. Place your idea on it, if you gave oneWhere it fits and who it competes with directly. A conclusion the evidence cannot carry is marked as inference.

What you get

  • One row per product: price, platform, buyer and weaknesses, each with the link that shows it.
  • The segments the market falls into, and the one least served.
  • What a newcomer would have to do better, according to the evidence.
  • Where your idea sits, if you described one.

Limits

  • It keeps no candidates. It maps a market and does not choose what you should build in it.
  • Private pricing, such as a quote on request, is marked unknown. Weaknesses are read for the five leaders only.

Pick another when

A market map typically costs about 45 credits. A broad market can cost more. These are typical figures, not a promise.

2.3 Check what you have

Improve my product

For builders with a product already in a project. It reads what the product does, finds the products your buyer compares it with, and judges each feature by whether it makes this buyer choose you.

You bring
A product, in a project that says who it is for
You get back
A feature plan written into your project
Typical cost
About 50 credits

What happens

  1. Read your projectIts candidates, documents, buyer and what the product already does.
  2. Find the products this buyer compares it withThey are what a feature has to win against.
  3. Read what each one offers and chargesFrom pricing and feature pages.
  4. Sort the featuresMost rivals have it: you need it to compete. Few have it and your buyer wants it: a wedge. Your buyer asks and nobody offers it: an opening.
  5. Check the effortWhether a free engine already does a feature, or it means new work.
  6. Write the plan into your projectBuild now, wedge, later or skip, with the evidence and effort beside each.

What you get

  • A document named Feature plan in your project.
  • A table of features against the competing products, with each product’s price.
  • Every feature sorted as must-have, wedge, opening or skip, then planned as build now, wedge, later or skip.

Limits

  • It needs a project. Without one it has no product to read.
  • It cannot see a competitor’s private roadmap or what customers say in private.

Pick another when

A feature plan typically costs about 50 credits. These are typical figures, not a promise.

3.1 Solve one part

Find a component

For builders who want to save time with open source. Describe the problem and its limits, such as the language, the licence and where it has to run, and get a ranked shortlist with one recommendation.

You bring
One technical problem and its limits
You get back
A ranked shortlist of repositories and one pick
Typical cost
About 20 credits

What happens

  1. Restate the problem and its limitsThe language, the licence and where it has to run decide what counts.
  2. Search the repository index and GitHubBy meaning and by words, so describing what the code does is enough.
  3. Read the strongest five to tenLicence, last activity, form (library, command line or API) and fit, read from the repository itself.
  4. Rank them and recommend oneWith what integrating it would take. Name a project and the shortlist is written into it.

What you get

  • A ranked shortlist of repositories.
  • For each: licence, last push, form, fit and what integrating it takes.
  • One recommendation.

Limits

  • It reads repositories. It does not run or test the code, so test your pick before you rely on it.
  • It runs no market research. It answers a technical question for the person building.

Pick another when

A component search typically costs about 20 credits, the cheapest of the seven. These are typical figures, not a promise.

Every kind

What holds for all seven

Every claim has a link
Each page the agent reads is saved to your library, and a result may only cite pages on file.
A stop is a result
When the evidence says nobody pays or the market is served, the verdict says so. See the sample verdict, which is a no.
Public pages only
It reads what anyone could read. Private sales, quotes on request and word of mouth leave no trace, and an empty search is never taken as proof.
You can steer it
Pin the buyer, rule out a field or ask why it kept something, in the chat beside the hunt, while it runs.
You pay for what it used
The maximum is set aside before a run, only what it used is taken, and a failed or cancelled run returns everything.

The full method, including where it goes wrong, is on how it works.

Questions

Do I need an idea to start a hunt?

No. From anywhere starts from a direction in your own words, or from nothing. You can name a field, a platform or a kind of customer, and say what to avoid.

What if I pick the wrong kind?

You can start without picking one. Describe what you are after, and the agent reads your message as one of the seven, says which and what you will get back, and asks you before it searches anything.

What happens if a hunt finds nothing worth building?

It reports the markets it looked at and why it passed on each. You pay for the work it did, and a stop is a normal result.

Does From a proven app reverse engineer the app?

No. It never downloads, installs, decompiles or runs the app. The case is written from public pages: the listing, pricing, documentation, changelogs, reviews and request boards. Every brief says to build from public behaviour only and never to copy the name, brand, icon, assets or text.

What if my idea has no competitors?

An empty market is a finding to explain. Check an idea looks for the reason, for example that nobody has tried, that people tried and stopped, or that something other than software already meets the need.

Are the credit figures fixed prices?

They are typical figures. Before a run, its maximum price is set aside. Afterwards only what it used is taken, and a run that fails or is cancelled returns everything. The billing page lists the range for each action.
