Buyer tools
20 lightweight tools for AI and hardware buyers.
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.
AI Modelsllm context window plannerLLM 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.
AI Modelsprompt routing savings estimatorPrompt 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 Modelsinference latency budget plannerInference 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.
AI Modelsmodel eval sample size plannerModel 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.
AI Toolsrag chunk size plannerRAG 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.
AI Toolsembedding storage cost estimatorEmbedding 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.
AI Toolsapi rate limit plannerAPI 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.
AI Toolsagent tool permission matrixAgent tool permission matrix
Agents are most useful when permissions are deliberate. This matrix separates safe read-only context from actions that need review, logging, or human approval.
AI Toolsbyok readiness checklistBYOK readiness checklist
BYOK can control cost and provider access, but it can also hide spend, leak credentials, and make vendor support unclear if ownership is sloppy.
AI Toolsai coding tool roi calculatorAI coding tool ROI calculator
Coding tools are valuable when they raise throughput without lowering ownership. This calculator keeps code review, testing, and onboarding cost in the equation.
AI Toolsprompt workflow automation scorecardPrompt workflow automation scorecard
Prompt automation should make repeated work more reviewable and reliable, not just faster. This scorecard makes the operational maturity visible.
AI Appsai meeting app privacy checklistAI meeting app privacy checklist
Meeting memory is useful precisely because it captures sensitive context. This checklist helps teams avoid turning private discussions into unmanaged company memory.
AI Appsai app export risk checkerAI app export risk checker
The more useful an AI app becomes, the more painful lock-in gets. This checker turns export claims into concrete tests.
GPUsvram fit checkerVRAM fit checker
VRAM decides whether a local GPU purchase works at all. Speed charts are secondary until the target workload fits reliably.
GPUslocal gpu break even calculatorLocal GPU break-even calculator
A local GPU is valuable when it is used often enough or unlocks privacy-sensitive work. Idle hardware is not cheaper than cloud because it feels owned.
Serversgpu cloud vs colocation calculatorGPU cloud vs colocation calculator
Colocation can lower unit cost for durable workloads, but it turns hardware into an operations commitment. This calculator makes that commitment explicit.
Laptopsai laptop thermal risk checkerAI laptop thermal risk checker
Launch specs rarely describe the daily pain. This checker focuses on simultaneous calls, browser work, compiling, external displays, and short local AI bursts.
Serversserver rack power calculatorServer rack power calculator
Server quotes often look clean until the facility cost appears. This calculator forces rack depth, circuit capacity, airflow, noise, and remote management into the decision.
Procurementai procurement red flag generatorAI procurement red flag generator
Most bad buys are not mysterious. They hide in vague exports, missing audit logs, weak tests, ignored power, unowned keys, and price assumptions that no one checks.
Quality score
How the pages are graded
Evidence quality
Scores need workflow tests, benchmark notes, practical constraints, and failure modes.
Fit guidance
Every page should say who the choice is for, who should avoid it, and when the answer changes.
Operating cost
AI and hardware reviews need price, time, power, maintenance, and switching-cost judgment.
Navigation value
Pages should route readers to the next useful review, comparison, or buying guide.
