Start here

Find the right tech buying path before comparing products.

Choose the situation that matches your budget pressure. Each path starts with a real buyer problem, then routes to the tools, reviews, comparisons, and cost checks that can change the decision.

PlanCapture role-based queries, answer with useful tools, route to review evidence, and convert serious readers to weekly test notes.

Onsite traffic plan

Turn high-intent searches into guided buyer paths.

01

Capture high-intent searches

Publish role and problem pages for founder stack, code review, procurement, local AI, and privacy queries.

02

Answer the first concern

Lead with the buying pressure, not a generic category intro, so visitors know the page is for them.

03

Route to proof

Send readers into tools, X vs Y pages, reviews, and cost checks that match the decision they are making.

04

Convert to test notes

Use the weekly notes signup after value is delivered, not as a gate before the answer.

Buyer tools

Quick checks before a shortlist

All 20 tools
AI Modelsai model cost calculator

AI model cost calculator

Use this before choosing a default model. The useful answer is not the cheapest token price; it is the cheapest solved task with acceptable latency and failure rate.

Founder, product lead, or engineering manager forecasting API spend before launch.
AI Modelsllm context window planner

LLM context window planner

Long context helps only when the model still follows instructions near the end of the prompt. This planner forces a fit check before a bigger context tier becomes the easy answer.

Team deciding whether long-context models, RAG, or smaller prompts fit a product workflow.
AI Modelsprompt routing savings estimator

Prompt routing savings estimator

Routing is useful when easy prompts are common and failure is observable. It is wasteful when every task is rare, expert, or hard to classify.

AI product owner trying to reduce spend without lowering output quality.
AI Modelsinference latency budget planner

Inference latency budget planner

A fast model can still feel slow if retrieval, tool calls, retries, and post-processing are not budgeted. This planner keeps the whole user path visible.

Product and infrastructure team designing an AI feature with strict response-time expectations.
AI Modelsmodel eval sample size planner

Model eval sample size planner

Small evals can still be useful if they are realistic and repeated. This tool makes the sample deliberate: enough cases to catch regression, not so many that no one maintains it.

Engineering team comparing models for code, research, support, extraction, or agents.
AI Toolsrag chunk size planner

RAG chunk size planner

Chunking is not a magic number. The right size depends on the shape of the source and whether the model needs local detail, full sections, or cross-document synthesis.

Builder designing retrieval for docs, support content, transcripts, policies, or code knowledge.
AI Toolsembedding storage cost estimator

Embedding storage cost estimator

Embedding cost is rarely just the first import. Refresh cycles, duplicate content, metadata, backups, and permission filters decide whether the system stays manageable.

Team sizing vector storage before importing docs, tickets, transcripts, or customer knowledge.
AI Toolsapi rate limit planner

API rate limit planner

Rate limits are product constraints. This planner helps choose batching, backoff, queueing, and multi-model fallback before launch traffic teaches the lesson.

Developer preparing production AI traffic across models, vendors, or internal apps.

Compare

Popular X vs Y decisions

AI Models vs GPUsCloud reasoning vs owned iteration

Frontier AI models vs Local GPU inference

Use frontier models for hard judgment; use local GPUs for private iteration and repeatable experiments.

Split the workload. Frontier models for correctness gates, local GPUs for iteration.
AI ToolsIndividual developer leverage vs repeatable team process

AI coding tools vs Prompt automation platforms

Coding tools give immediate developer leverage; prompt automation platforms matter once work becomes a repeatable process.

AI coding tools first, prompt automation after patterns stabilize.
Laptops vs WorkstationsMobility vs sustained local compute

AI laptops vs Desktop workstations

Buy the laptop for mobility and daily work; buy the workstation when sustained GPU load is the actual job.

Laptop for most builders, workstation for sustained local AI.
AI ModelsQuality escalation vs throughput

Frontier reasoning models vs Fast utility models

Use frontier reasoning for costly mistakes; use fast utility models for volume.

Frontier reasoning for review gates, fast utility models for routine production flow.
AI AppsPersonal recall vs governed company memory

AI notebook apps vs Team knowledge bases

Use AI notebooks for individual recall; use a governed knowledge base when the company depends on the answer.

AI notebook for personal productivity, team knowledge base for shared operating memory.
ServersRack density vs office tolerance

4U GPU servers vs Edge inference nodes

Buy 4U when operations owns the room; buy edge nodes when people have to work near the hardware.

4U servers for controlled racks, edge nodes for office-friendly inference.
GPUs vs ServersDesk-friendly iteration vs serviceable shared infrastructure

GPU workstations vs Rack inference servers

Buy the workstation for private eval loops; move to rack inference only when utilization, operators, and facilities are real.

Workstation first for discovery, rack server after recurring shared demand is proven.
