Greg Isenberg's eight-tool roundup is less about collecting GitHub stars than spotting a small job someone will pay to have done. His picks span a launch video, public customer research, local dubbing, editable slides, coordinated coding agents, free-tool planning, idea interrogation, and interface critique. This guide links the original maintainer repos, gives one first test for each, and separates a plausible business use from a promised outcome.
Start with a buyer and one repeated problem, then pick one tool that helps deliver or validate the solution. Brag and Agent Reach are Greg's top picks because one makes work easy to show and the other helps find the pain behind a market. A free repository does not make a free business: model usage, hardware, rights, permissions, maintenance, and human review still matter. His ten-clients-at-$1,000 example is $10,000 in monthly revenue before costs, not a forecast.

Which Tool Fits the Job?
| Tool | Use it for | First honest test | Business angle |
|---|---|---|---|
| Brag | A short project launch video and share copy. | Make a 20-second clip for your own project, then check every claim and asset. | Offer a reviewed launch-video package for a niche you know. |
| Agent Reach | Research public conversations across social and video sites. | Collect ten attributable complaints around one workflow; interview three people. | Customer-discovery brief, not an automated contact list. |
| VoiceStudio | Local speech, voice work, transcription, and dubbing. | Dub one tutorial using your own voice, then get a fluent review. | Multilingual help-video upkeep for a business with repeated questions. |
| PPT Master | Editable PowerPoint decks from notes or a template. | Rebuild a public or redacted proposal and inspect slides in PowerPoint. | Proposal or training-deck production with human fact-checking. |
| OpenRig | Coordinate Claude Code, Codex, or other coding sessions. | Use one disposable repo and two bounded roles: build, then review. | Internal delivery system for a service; not a client outcome by itself. |
| Free Tools | Plan a useful calculator, checker, or other lead magnet. | Show a rough tool to five likely buyers before polishing it. | Free-tool strategy and build for a specific industry. |
| Grill Me | Expose assumptions through a structured conversation. | Grill one product claim and write down what needs customer evidence. | Improve your own discovery work; do not sell the AI interview as proof. |
| Impeccable | Critique and refine an agent-built interface. | Run critique and audit on a live page, then check it with a person. | Focused design-and-usability review with before/after evidence. |
1-2. Show the Work, Then Find the Problem
Brag: a launch film as the first deliverable
Brag turns a project into a short video with motion, music, and post copy. The project's Brag Slim route accepts a project directory or website URL and is designed for Opus 5.5; the full route uses Hyperframes. Greg's suggestion is to make an example for someone whose product you understand, then start a conversation from actual work rather than an empty pitch. Review visual accuracy, licensing, music, and client approval before publishing. A compelling demo can open a door; it does not prove a retainer exists.
Agent Reach: research the workaround, not just the keyword
Agent Reach wires an agent to platform-specific research tools. Greg looks for phrases such as "I export it" and "I copy this into" to find manual steps that still cost people time. Keep source URLs, note the poster's context, and ask permission before turning a public complaint into outreach. Some platform paths use authenticated sessions or cookies; the maintainer warns about account and credential risks. Check terms of service and do not hand a primary account's session to a downloaded tool just to run a quick market scan.
3-5. Produce the Deliverable Without Losing Control
VoiceStudio: a consented dubbing service
VoiceStudio runs voice generation, transcription, and dubbing with local models. Greg's service idea is to translate tutorials that answer a company's three most common support questions, then maintain them as the product changes. Start with your own voice or explicit voice-owner consent, and have a fluent speaker check meaning, pronunciation, timing, and claims. The maintainer's install guide helps match engines to hardware; CPU-only machines can run slowly, and models require downloads and disk space.
PPT Master: make a deck that remains editable
PPT Master aims to export native PowerPoint elements, including shapes and charts, rather than a pile of flattened slide images. It also accepts a company template. A good first test is a proposal you already know well, with client details removed: compare its narrative, numbers, layout, and editability with the source. Do not upload confidential notes or represent unverified charts as research.
OpenRig: coordinate agents, then inspect the permissions
OpenRig manages persistent coding-agent sessions, roles, and shared work. This is an operations tool for someone already delivering software, not a shortcut to a finished product. Its setup documentation says rig setup can install missing tools and write tmux configuration; it offers a dry run. Review changes and each agent's effective permissions before running it near client code or secrets.
6-8. Pick the Right Idea and Improve the Result
Free Tools: a lead magnet with a real job
Corey Haines' Marketing Skills collection includes Free Tools, formerly called free-tool-strategy. It helps plan calculators, generators, and checkers that solve a small problem before asking for a sale. Choose a result a buyer can verify, such as a quote estimator or preparation checklist, rather than a generic AI widget. Track qualified use and follow-up conversations, not just visits.
Grill Me: useful questions are not customer evidence
Matt Pocock's Grill Me guide describes a stateless interview that presses on assumptions one round at a time. Greg uses it when excitement would otherwise hide a weak premise. Install from Matt's repository and check the current dependency notes: the grill-me entry point calls the underlying grilling skill. Record the claims it reveals, then ask a customer; a model's questions cannot validate demand alone.
Impeccable: critique before polishing
Paul Bakaus' Impeccable gives coding agents a design vocabulary: critique for hierarchy and clarity, audit for technical quality, then polish, bolder, or quieter when the direction is known. Tell it who the page serves and what action matters. A useful service is a measured design fix with before/after screenshots and a usability check, not a claim that an automated score proves conversion lift. Read the skill and any hooks before installing it in a client's workspace.
The Real Cost and Permission Check
- License and distribution: "free to download" is not the same as rights to resell outputs or redistribute a model. Read each repo's license, model license, and media-asset terms for your exact service.
- Usage cost: Count model/API calls, GPU or CPU time, downloads, storage, hosting, editing, and human review. For a local voice workflow, hardware and labor may matter more than token prices.
- Access: Skills and agents can run code, change settings, or see files. Inspect scripts and permissions in a test workspace. Use public or redacted examples before customer data.
- Evidence: A free video, research brief, deck, or design fix can create a conversation, but track qualified replies, paid pilots, retention, and delivery margin before calling the business repeatable.
Greg's example of ten clients paying $1,000 each is simple revenue arithmetic: $10,000 per month before expenses. It is a useful target for pricing a service, not evidence that a GitHub repo will acquire ten clients.

Turn One Repo Into a Buyer-First Pilot
The quickest useful experiment pairs one buyer problem with one or two tools. This prompt starts with the customer and makes the permissions, cost, and proof visible before you turn a demo into an offer.
Choose a tool, test a service
Three options, one seven-day pilot, no invented traction.
