Dume vs Saner.AI: Which AI Executive Assistant Should You Use in 2026?

Search best AI executive assistant in 2026 and the results all promise the same thing — hand over your inbox, your calendar, and the follow-ups you keep forgetting. Two names that keep surfacing are Dume and Saner.AI. They overlap enough to look interchangeable. They aren't.

Saner.AI is a knowledge-first assistant built explicitly for people with ADHD. It pulls your notes, emails, files, and calendar into one searchable brain, then a task assistant called Skai turns that pile into a plan. Pricing starts free and runs to $16/month (saner.ai/pricing, 2026).

Dume comes at the same problem from the opposite end. Instead of building a second brain first, it starts with execution across the channels you already use — browser, WhatsApp, phone — and extends onto your desktop through Dume Cowork. This breakdown covers where each one earns its keep, using pricing and features published on each company's own site.

Key Takeaways

• Saner.AI's free plan caps you at 30 AI messages and 30 AI requests per month; Dume's free-forever plan gives 1,200 credits a year and 20 messages a day (saner.ai/pricing; dume.ai/pricing, 2026).
• Saner.AI does not include GPT, Claude, or Gemini in any plan price — external models are billed per token, or you supply your own API key (saner.ai/pricing, 2026).
• Saner.AI runs in the browser, a Chrome extension, and a mobile app; Dume adds two-way WhatsApp, Telegram, and Slack control plus phone calls on PRO and MAX.
• Saner.AI's genuine edge is proactive knowledge work — connecting notes, emails, and PDFs into answers you'd otherwise have to hunt for.
• Dume's edge is doing things off the screen: file organization, spreadsheets, and drafted reports through Dume Cowork.

What Saner.AI Does Well

Saner.AI built its product around a specific person: someone whose information is scattered and whose working memory won't hold it. One co-founder has ADHD, and the design follows from that — capture anywhere, distraction-free notes, and an assistant that resurfaces things before you've remembered to look (saner.ai, 2026).

The knowledge layer is the strongest part. Saner syncs Google Drive, email, Slack, and calendar, runs OCR on files, and lets you ask questions across everything you've saved even when you've forgotten the exact wording. Saner says some users have imported over 3,000 notes into it. If your real problem is “I wrote it down somewhere,” this is a good answer to it.

Skai, the task assistant, then closes the loop — turning emails into tasks, brain dumps into plans, and proactively suggesting what to work on next. That proactivity is the feature Saner's own featured customers highlight. It's a legitimate strength, and Dume doesn't do the second-brain synthesis part as deeply.

Two limits are worth knowing before you commit. First, the free tier is tight: 30 AI messages and 30 AI requests per month, 100 notes, 100MB of storage. Second — and this catches people — access to external models like GPT, Claude, and Gemini is availability, not inclusion. You pay per token on top of your subscription, or bring your own API key (saner.ai/pricing, 2026). Saner also still describes itself as a beta product.

Where Dume Takes a Different Approach

Dume assumes the bottleneck isn't recall — it's the fifty small actions sitting between you and a finished day. Dume Assistant triages email, drafts replies, and delivers a daily morning briefing, then connects into tools like Notion, Jira, Slack, and Google Workspace to actually move work forward.

The bigger difference is where you can reach it. Saner.AI lives in a browser tab, a Chrome extension, and a mobile app. Dume adds two-way messaging over WhatsApp, Telegram, and Slack on PRO and MAX, plus phone calls on those same plans — so you can hand off a task from a taxi without opening anything (dume.ai/pricing, 2026).

Dume Cowork extends the same assistant onto your desktop. Point it at a folder and it will sort the files, pull the numbers into a spreadsheet, and draft the report — the category of work most chat-based assistants stop short of.

On models, Dume takes the opposite position to Saner.AI. Model access is part of the plan rather than a metered add-on: Basic models on Free, Standard on GO, Premium on PRO, and all frontier models on MAX. And the free tier is a real product rather than a trial — 1,200 credits a year, 5 agents, 20 messages a day, no card required.

Side by Side

Choose Saner.AI if…

• Your core problem is scattered information — notes, PDFs, meeting transcripts — and you want one place that can answer questions across all of it.
• You have ADHD or similar executive-function challenges and want a tool designed around that from the ground up, not retrofitted.
• You mostly work at a desk, and browser plus a mobile app is enough reach for you.
• You already pay for GPT or Claude and are happy to plug in your own API key.

Choose Dume if…

• You want a free plan you can actually run on, rather than a 30-message-per-month sample.
• You need to control your assistant from WhatsApp or a phone call, away from a laptop.
• You want the model included in the price, from basic up to frontier, with no per-token billing on top.
• Your unfinished work lives in files and folders, not just notes — and you want reports and spreadsheets produced, not only found.

The Bottom Line

These two tools solve adjacent problems that feel like one problem. Saner.AI is the better second brain: if you're drowning in information you've already collected, its synthesis and proactive nudges earn the money, and the ADHD-first design is more than marketing. Dume is the better operator: broader channels, desktop file work, model choice inside the plan, and a free tier generous enough to judge the product on. If you can't tell which problem you have, start on both free plans — Dume's costs nothing indefinitely, and Saner's needs no card either.
