Alter offers a useful local-first AI layer across Mac applications, but cloud routing, fair-use limits, permissions, local backups, and model quality need a deliberate test.

Use a non-sensitive workspace for ten days. Run 40 repeat tasks across selected text, document questions, meeting notes, and local versus cloud models. Measure accepted outputs, meaning-changing edits, latency, local resource use, provider calls, permission prompts, memory errors, backup and deletion behavior, and effective cost per accepted task.

Reusable trial worksheet
Turn this review’s buyer test into evidence. Your entries autosave only in this browser and are never added to shared shortlist links.
Confirm the tool meets every must-have workflow and stakeholder requirement.
Review starting point: Mac users working across many applications; Local-model and BYOK workflows; People who want voice, memory, and document context together
Run the same representative work you would use in production; do not score a polished demo.
Review starting point: Complete three to five representative tasks with known acceptable outcomes and compare them with your current process.
Calculate the effective cost per accepted result, including usage, review, corrections, and required add-ons.
Review starting point: Alter documents a free core app for local models or bring-your-own API keys, a seven-day trial, Local+, Pro, and a one-time Lifetime option. The public documentation explains plan boundaries but does not expose durable dollar prices for every paid option, so verify the in-app checkout. Pro uses a monthly fair-use budget; its API gateway allows 200 requests…
Define an acceptance threshold, test known answers and edge cases, and record every correction.
Review starting point: Editorial quality signals: features 4.2/5; AI quality 4.0/5. Validate these signals in your own work.
Verify what data enters the product, who can access it, how long it is retained, and whether it trains models.
Review starting point: Use approved low-risk data first. Check roles, consent, deletion, subprocessors, model-training settings, and the contract—not only the marketing page.
Test the real handoffs, permissions, failure states, and export path your team depends on.
Review starting point: macOS, Ollama, OpenAI-compatible APIs, Cloud model providers, API gateway
Record training, governance, reliability, accessibility, ownership, and change-management risks before rollout.
Review starting point: Mac-only workflow; Local data needs manual backup; Paid unlimited use has fair-use boundaries

Yes. Alter says core features remain free with local models or your own API keys, with no credit card required.
Yes. Its documentation says chats, transcripts, recordings, memory, and workspace data stay on the Mac by default and are not cloud-synced.
The app remains usable through the free BYOK/local path; paid plans add managed models, routers, remote tools, and support.
Not without boundaries. Alter documents a monthly fair-use budget, possible lower-cost routing, and API-gateway throttling after 200 daily requests.
